Authors: Suthar Dipak , Vegad Tushar
Published: June 2017

Background: The present study was carried out with the objective to assess the influence of morbid obesity on the outcome after TKR and with the aim to compare the outcome following TKR in a consecutive series of morbidly obese patients (BMI >40 kg/m2), and matched it with group of non-obese patients (BMI <30 kg/m2).

Methods: The study period planned was of two years. The totals of 100 patients undergoing total knee replacement were selected for the study period. On the basis of body mass index inclusion criteria for the two groups were decided. Of the total 100 patients, they were divided into two groups. One group 1 consisted of obese patients with total of 50 patients and group 2 consisted of non-obese patient with total of 50 patients.

Results: At the end of two years when the data was compared with the preoperative assessment, it was found to significantly better where value of p was <0.001.  However when the comparison was done between the two groups, it was found that scores were lower in the group 1 patients which included the obese patients.

Conclusions: Total knee arthroplasty is a safe and efficacious operation in obese patients with no significantly greater risk of complications. However, post-operative clinical scores and absolute improvement in the scores are statistically superior in non-obese patients at one year follow-up. Obese patients should be started on weight loss programs and counselled about possible inferior results for total knee replacement.

Authors: Kulambi Vijaykumar , Shetty Subodh , Ghantasala Venkatesh , Bhagavati Vishwanath
Published: June 2017

Background: From long time clubfoot has been a clinical challenge to orthopaedic surgeons. It is one of the commonest congenital deformity of the musculoskeletal system in children. Each year more than 1,00,000 babies are born with congenital clubfoot. 80% of which occur in developing countries.

Methods: 60 feet in 40 children were treated by the Ponseti method from September 2014 to august 2016. Prospective follow up for a mean duration of 18 months was undertaken. The deformity was evaluated by Pirani score before and after the treatment. At the end of treatment all feet were functionally classified into good, fair and poor.

Results: The average number of casts applied before full correction was 8. 21.66% of the feets needed tenotomy before full correction. 90% of the patients showed good results, 3.3% had fair results and 6.6% of patients had poor results. There was a significant difference in the pre-treatment and post-treatment pirani score values.

Conclusions: Ponseti method of manipulation and plaster casting is very effective to correct club foot deformity.

Published: June 2017

Background: Intracapsular fracture neck of femur has always presented great challenges to every Orthopaedic surgeons and it is remain a mystery whether to fix or to replace the fracture in the elderly. The aim of the study was to analyze the functional outcome of two widely used and accepted modalities of treatment in the age group 57-75 years, in Garden’s type I and II fractures, namely (a) cannulated cancellous screw fixation(internal fixation) and (b) modular bipolar prosthetic replacement of the femoral head (hemiarthroplasty).

Methods: The total 110 patients were including in the study from age groups 57-75 (mean age 66). The Garden classification of fracture neck of femur was used to evaluate the displacement of femoral neck fractures. Only grade 1 and 2 was included in the study. 55 patients were included in each group A and B. Osteosynthesis (fracture fixation) was carried out by closed reduction and insertion of cannulated cancellous screw and in other group hemiarthroplasty was done.

Results: In group A 55 patient with fracture neck of femur was treated by osteosynthesis i.e. fixation using 02 or 03 cannulated cancellous screw and in group B, 55 patients with fracture neck of femur was treated by modular bipolar replacement hemiarthroplasty. In Group A out of 55, 41 patients union was achieved between 08 to 14 months (mean 11.5 month), 09 patients developed non-union even after 16 months and 05 patients develop collapse of head with AVN with shortening at end of 02 year, however in Group B out of 55 patients 51 patients started walking after 2nd postoperative days, 02 patients developed infection, and 02 patients developed posterior dislocation.

Conclusions: The fracture fixation may be tempting for fracture neck femur in age group 57-75 especially of Garden Type I but internal fixation put risk of non-union and AVN and second surgery may be required after few months or years  if patients survive. Based on results in our study we therefore can conclude that in Garden Type I and II femur neck fractures in the patients between 57-75 years of age, hemiarthroplasty is the better modality of treatment.

Published: June 2017

Background: Postextraction alveolar bone loss, mostly affecting the buccal plate, occurs despite regenerative procedures. To better understand possible determinants, this prospective case series assesses gingival blood perfusion and tissue molecular responses in relation to postextraction regenerative outcomes.

Methods: Adults scheduled to receive bone grafting in maxillary, non‐molar, single‐tooth extraction sites were recruited. Clinical documentation included the following: 1) probing depth (PD); 2) keratinized tissue width (KT); 3) tissue biotype (TB); and 4) plaque level. Wound closure was clinically evaluated. Gingival blood perfusion was measured by laser Doppler flowmetry (LDF). Wound fluid (WF) and gingival biopsies were analyzed for protein levels and gene expression, respectively, of relevant molecular markers. Bone healing outcomes were determined radiographically (cone‐beam computed tomography). Healing was followed for 4 months.

Results: Data from 15 patients are reported. Postoperatively, neither complications nor changes in PD, KT, or TB were observed. LDF revealed decreased perfusion followed by hyperemia that persisted for 1 month (P ≤0.05). WF levels of angiopoietin‐2, interleukin‐8 (IL‐8), tumor necrosis factor‐alpha (TNF‐α), and vascular endothelial growth factor peaked on day 6 (P ≤0.05) and decreased thereafter. Only IL‐8 and TNF‐α exhibited increased gene expression. Linear bone changes were negligible. Volumetric bone changes were minimal but statistically significant, with more bone loss when membrane was used (P = 0.05).

Conclusions: Gingival blood perfusion after postextraction bone regenerative procedures follows an ischemia‐reperfusion model. Transient increases in angiogenic factor levels and prolonged hyperemia characterize the soft tissue response. These soft tissue responses do not determine radiographic bone changes.
Koiné y aticismo en el tratado de Galeno Sobre los procedimientos anatómicos
Authors: Redondo Jordi
Published: June 2017

El tratado Sobre los procedimientos anatómicos ofrece un extenso corpus para el estudio de la lengua literaria de Galeno. La naturaleza de ésta ha sido alineada tanto en las filas de un aticismo moderado como en las del antiaticismo. Frente a esta segunda opción, que abunda en la definición de la obra desde una óptica que excluye todo fin literario de la misma, los frecuentes recursos retóricos muestran un buen conocimiento de la prosa artística por parte de nuestro autor. Ahora bien, el análisis de la lengua demuestra que está basada en la koiné no literaria.

Revealing the Phenomena of Heat and Photon Energy on Dealing Matter at Atomic level
Authors: Ali Mubarak
Published: June 2017

Technology is in the way to reach in its climax but the basic understanding of science in many phenomena is still awaited despite the fact that nature justifies all those. Scientific research reveals strong analogy between electron and photon. Atoms that execute suitable electronic transitions, on absorbing heat energy at shunt level, excite their electrons. De-excitation of an electron under the gravitational force of its nucleus, where inertia is involved, results into depicting energy in the shape like Gaussian distribution. The wavelength of photon remains in inter-state electron’s gap where the source of generating energy in wave-like fashion is due to confined electron-dynamics of that atom eligible to execute electronic transition; energy configures under electron’s trajectory while excitation period is due to inertia-levitation-inertia behaviours and energy configures under electron’s trajectory while de-excitation period is due to inertia-gravitation-inertia behaviours. Silicon atom is a model system of it. Uninterrupted confined inter-state electron’s motion results into configure force energy that can travel immeasurable length where interruption from the point of generation termed it a photon. Such photons increase wavelength under decreasing energy. Here, I discuss that heat energy is due to merged photons or squeezed photons and photonic current is due to the configuring energy in inter-state electron’s gap under confined electron-dynamics of the atom. Force of repulsion or attraction in certain materials engages the phenomenon of levitism or gravitism where inertia is exempted. Structural motifs and dynamics are subjected to characteristic photons as long as atoms are dealing neutral behavior of field forces. A structural design delivers straight-forward application on dealing photons of certain wavelengths. Here, heat energy and photon energy explore matter at electron level. Thus, devise science to describe.
Fabrication of novel thermal-expandable microcapsules and their applications in intumescent flame-retardant water-based coatings
Authors: Yuan Teng , Zhang Chaoqun , Zhou Chuang , Tu Weiping , Hu Jianqing , Yang Zhuohong
Published: June 2017

Thermal-expandable microcapsules (TEMs) for water-based coatings were synthesized with co-polymer of Acrylonitrile (AN) - Methyl methacrylate (MMA) - Ethylhexyl acrylate (EHA) - Divinylbenzene (DVB) as shell and toluene-p-sulfonyl hydrazide as core by suspension polymerization method. It was found that the microcapsules with desirable thermal expansion property and good heat stability could be obtained with a shell monomers composition of 70% AN /20% MMA /9% EHA /1% DVB. When 2% styrene-maleic acid copolymer (SMC) as emulsifier and 3% poly (vinyl pyrrolidone) (PVP) as dispersing agent were used, well defined spherical and more uniform microcapsules could be prepared. It was also found that when the shell/core mass ratio was 3:1, an encapsulation efficiency of ca. 94.5% could be achieved. Beyond this ratio, the increase of encapsulation efficiency reached a plateau. The 100 μm thickness film of water-based coating containing 5% microcapsules could be expanded to the thickness of 450 μm after exposed at 150 °C for 2 minutes. TG analysis revealed the mass loss start temperature of coating increased by more than 30 °C when 5% microcapsules were added to water-based coatings, which demonstrated the flame-retardant function of the coatings.
Influence of Income on Shopping Behavior of Residents and Feasibility of Neighborhood Shops: A Study of Selected South Delhi Localities
Authors: Mazumdar Gargi Kar
Published: June 2017

Metro cities of India are going through rapid phase of socio-economic development accompanied with changing standards of living and a rise in purchasing power of population. This increasing expenditure pattern calls for increase in business and commercial outlets in the cities. This is more so noticeable in  NCT of Delhi where due to  limited availability of urban land for multi functional land use, both  planned and unplanned commercial areas are emerging fast to cater to the needs and demands of local population. However, the impact of income as well as other socio-economic factors play an important role in defining the spatial pattern of movement of shoppers which in a way define the survival of neighborhood (both planned and unplanned) shopping centers/ shops. The aim of this research paper is to understand the impact of income in defining the spatial pattern of shopping behavior of the consumer in patronizing the neighborhood shops or markets for various food and non food items. Thus, the present study focuses primarily on identification of shopping patterns / behavior of residents of selected localities in South Delhi. This study is conducted over  two economic categories of localities: lower and middle income category locality consisting of areas like Gobind Puri, Gobind Puri Extension and Kalkaji DDA Flat localities; and upper middle and higher income locality consisting of areas like C.R.Park, Kalkaji Main area (excluding DDA LIG, Janta, Slum category flats) and Alakananda. The rationale behind the selection of these two separate socio- economic areas for the survey is to analyze the inter locality and intra locality comparison of shopping behavior of various income class of population. 

The findings of the study favors the feasibility of the local shops in the surveyed localities, since nearness to the market and ease of shopping has encouraged the survival of the local shops/ markets operating in the residential colonies especially for food items. However apart from income levels, standard of living is also influencing the shoppers behavior and growing trend of shopping from Malls and Plazas is also noticed showing changing preference of shoppers for well established market areas than local shops especially for non food items. Through GIS based mapping, the movement of shoppers for both food and non food items is traced and specific suggestion are given regarding the changing land use under commercial activities in the survey areas. Area specific suggestions are given in the light of Master Plan of Delhi 2021.

Published: June 2017

Steel is one of the most important pillars to the Infrastructural development of any nation. The rate of production and consumption of steel is treated as an important index of the level of socioeconomic development and standard of living of the people in any country. India stands at the 3rd position as a producer of crude steel in the world and this Industry is an important Foreign exchange Contributor to the economy. Since Iron  and  steel  products  are  Imported and Exported  liberally  as  per  the existing   policy and therefore it becomes necessary  to  analyse and evaluate the export potentials and competitiveness of the Indian Iron and steel industry in relation to the steel exports of the world as a whole. This study analyses the competitiveness and the pattern of trade flows/trade specialisation from India to world, particularly for Iron and Steel industry. Our research is mainly based on the measures of Revealed Comparative Advantage (RCA) measures or Balassa Index.
FIBROSA PRZECIW FAIRBAIRN - POLSKA SPÓŁKA, IZBA LORDÓW I PRAWO RZYMSKIE

Fibrosa v. Fairbairn. Polish Company, House of Lords and the Roman LawSummaryThis paper deals w ith the development of the British doctrine of unjust enrichm ent, influenced to some extent by condictiones of the Rom an law. At the beginning of the XXth century the common law recognized two contradictory views on the restitution of „solutio indebiti”. According to „coronation” cases losses arising from performance of a contract up to the moment of a frustration - should lie where they fall, which was unjust and did not meet the needs o f trade. This attitude was changed by the House of Lords when two very similar cases: Cantiere and Fibrosa were heard. Fibrosa S.A. was a Polish com pany that sued Fairbairn for the money paid in advance for machine parts that were finally not delivered. The reason why the contract was frustrated was the outbreak of the war. The case was decided on the basis of the Rom an law condictio causa data causa non secuta and became a precedent for the modern com m on law world. The paper also discusses the suitability of using the causa data causa non secuta, where causa fm ita seems to be a better solution, and the question whether causa data causa non secuta could be used outside contracts.

An Organisational Form of a Joint Stock CompanySummaryA joint stock company constitutes the most organised and formalised type of a commercial partnership in the Polish law. Its economic significance results from the aim of such a legal construction to conduct huge business ventures requiring an engagement of considerable financial and human resources. Thus, the legislator regulated the topic of a joint stock company in a much detailed manner than in case of other commercial partnerships, including a limited liability company. Hence, a joint stock company is a pure type of an association of capital, without personal elements, which causes that its functioning is subjected to the formalised rules specified by the provisions of the law. These rules not only describe the precise manner of actions during the formation of the joint stock company but also assign three basic stages of the legal being of the company. These stages are described in the legal study as organisational forms of a joint stock company and they include: (i) the stage of organisation, so-called joint stock company in organisation, in which actions aimed at the formation of the company and obtaining of the status of a legal person are being undertaken. At this stage, the company in organisation already has the status of a legal person, therefore it may participate in the legal trade as its participant with full rights; (ii) stage of the proper company, which begins with the moment of registering the company in the court register, which means obtaining the legal personality by the company. From that moment, the joint stock company begins its statutory activity; (iii) stage of the company in liquidation, in which the actions aiming at the termination of the legal being of a joint stock company and its removal from the court register are undertaken.

A P e r m a n e n t P r o h ib it io n t o D r iv e V e h ic l e sSummaryTaking into consideration present needs of security in communication, the legislator has significantly modified the regulations concerning prohibition to drive vehicles. In art. 42 § 3 and § 4 of the Penal Code (hereinafter referred to as „PC”) the prerequisites of facultative (§ 3) and obligatory (§ 4) application of this measure are defined. From the beginning of the validity of this regulation it has been a subject of discussions in the legal doctrine. As far as discussed regulation seems to be coherent with demands of everyday users of law and is fully justified by increasing traffic offence, especially connected with perpetrator’s state of insobriety, the text of some of the provisions cause many interpretative problems. This study tries to determine some of the aspects concerning facultative and obligatory grounds for adjudicating the measure. The main doubts are caused by a wide definition of the persons, who may be punished with this measure (art. 42 § 3 PC). It provides that, this measure may be applied to the „person participating in a street traffic”, but not only to a driver of a vehicle but also to a pedestrian, if on conditions described in the regulation, he would commit one of the mentioned offences. In case of a graded form of the prohibition, viz. to be applied for a lifetime, described in art. 42 § 4 PC, special severity results from its obligatory adjudication, which brought out objections connected with restricting the court’s discretion. A permanent prohibition of driving any vehicle is a very repressive sanction, especially when applied to professional drivers. It may turn out that the most severe sanction adjudicated for a traffic offence from art. 42 § 3 or § 4 PC, is connected with lasting for life stigma, because, in accordance with Polish Penal Code, a person to whom it was adjudicated, will be regarded as a man with a criminal record.

The Philosophy of Law in Ulpian’s Life and TeachingSummaryThe purpose of this article, is to show, taking into account Ulpian’s life and teaching, that the Roman jurisprudence was interwoven with some elements of philosophy. The first part of the article illustrates the influence of Ulpian’s life history on his philosophical and legislative views, whereas the second part presents the latter.His knowledge of law, the posts which he occupied, and numerous works prove that Ulpian was preoccupied with studying „law through its first causes”. He asked about the essence of the law, about what the natural law is, and what justice is. He described the juridical reality using the language of law and philosophy. His concept of lawfulness can be perceived as integral, combining material and formal legality He did not depart from the ethical dimension of law although he respected the rigours of the formalised norms. Referring to aequitas did not disturb him in paying attention to certitudo legalis. In his concept of lawfulness one can see a reference to Cyceron’s ideas and in his concept of natural law one can observe a reference to the Stoics. In the field of the penal lawfulness one can perceive Ulpian as a precursor of the ability to perceive the human equality in the sphere of natural law, the concept elaborated as late as several centuries afterwards. Perceiving the equality of people, approximates him to the Christian’s philosophical idea.

Removal of Organic Matter and Etodolac from Pharmaceutical Industry Wastewater by PAC Adsorption
Authors: Vergili Ilda , Gencdal Sezin
Published: June 2017

The removal of organic matter and etodolac (an anti‐inflammatory pharmaceutical) from a real process wastewater by using powdered activated carbon (PAC) adsorption before and after Fenton oxidation has been studied. The wastewater sample is collected from the final stage of chemical synthesis of a pharmaceutical (etodolac). Fenton oxidation resulted with decrease in chemical oxygen demand (84% removal) and etodolac concentration was reduced to 0.7 mg L−1. Optimum adsorption equilibrium conditions were found as t = 16 hours, and m = 10 g L−1. The Freundlich model showed the best fit for the adsorption of both wastewater with R2 values of 0.89 and 0.99. Lower pseudo‐second‐order rate constant (k2) (0.067 < 2.62) obtained from the adsorption of raw wastewater with higher organic matter concentration confirms the chemisorption of the adsorbates onto the PAC. Pore surface mass diffusion with R2 value of 0.92 was found as rate‐controlling step for adsorption process with Fenton pre‐treated wastewater.

Background. Clubfoot is the most common deformity in arthrogryposis and is characterized by a high degree of rigidity and a tendency to relapse. At present, no consensus exists on the issue of treatment of this pathology. The aim of this study was to demonstrate the possibilities of Ponseti method for the treatment of clubfoot in the younger children with arthrogryposis. Material and methods. The study was based on an analysis of treatment outcomes in 64 children (124 feet) under 3 years. 50 patients (78%) had a congenital multiple arthrogryposis, 14 children (22%) had a distal form of the disease. All the children underwent conservative treatment using Ponseti method. Results. After phased plastering by Ponseti method, the children with congenital multiple arthrogryposis aged under 1 year demonstrated correction of deformity components in 25 (48%) feet and the children from 1 to 3 years in 4 (8.7%) feet. Phased plastering in the children under 1 year with the distal form of the disease resulted in the correction in all 7 (100%) feet. In the patients with a similar form of the disease aged from 1 to 3 years, correction was achieved in 3 (23%) feet. In the cases of incomplete correction of deformity elements, when the possibilities of phased plastering were exhausted, different surgical interventions were performed. However, in neither case the surgery to remove talus was required. Conclusion. Ponseti method is most effective for the treatment of clubfoot in the children of the first year. Application of this method allows for elimination of clubfoot or significant reduction of the volume of subsequent surgery.

Authors: Sapogovkiy A. V. , Kenis V. M. , Khusainov R. H.
Published: June 2017

Tarsal coalition - is an abnormal fusion between two or more tarsal bones which can lead to foot pain, progressive foot deformity, and frequent ankle sprains. Radiological diagnosis of tarsal coalitions on the standard plain radiographs is difficult because of indirect visualization of the fusion zone. Computed tomography is helpful for confirmation of the diagnosis. Purpose: to determine diagnostic value of indirect radiological signs of tarsal coalitions. Material and methods. The analysis of the radiographs of 25 patients with confirmed tarsal coalitions and the radiographs of 37 patients with valgus deformities of feet without tarsal coalitions. Results. The sensitivity and specificity of tarsal coalitions radiological signs were determined. Sensitivity of the "anteater nose" in our study was 92,3%, specificity - 94,31%; C-sign had sensitivity 88,89% and specificity - 77,08%; “talar beak” symptom had sensitivity 36,36 percent and specificity - 97,14%. Conclusion. Sensitivity and specificity of indirect radiological signs of tarsal coalitions determined in our study have sufficient diagnostic value, and computed tomography of the foot should be done for confirmation of diagnosis.

In histopathologic SLIM diagnostic (synovial-like interface membrane, SLIM) apart from diagnosing periprosthetic infection particle identification has an important role to play. The differences in particle pathogenesis and variability of materials in endoprosthetics explain the particle heterogeneity that hampers the diagnostic identification of particles. For this reason, a histopathological particle algorithm has been developed. With minimal methodical complexity this histopathological particle algorithm offers a guide to prosthesis material-particle identification. Light microscopic-morphological as well as enzyme-histochemical characteristics and polarization-optical proporties have set and particles are defined by size (microparticles, macroparticles and supra- macroparticles) and definitely characterized in accordance with a dichotomous principle. Based on these criteria, identification and validation of the particles was carried out in 120 joint endoprosthesis pathological cases. A histopathological particle score (HPS) is proposed that summarizes the most important information for the orthopedist, material scientist and histopathologist concerning particle identification in the SLIM.

The aim - to compare the results of simultaneous bilateral and unilateral surgical correction of hallux valgus and to create recommendations for treatment of the patients with this pathology. Material and methods. The authorse analyzed the data of 40 patients (60 feet) who carried out an operative treatment of hallux valgus in SPb multiprofile city hospital N 2 since 2011 to 2013. Functional (AOFAS score) and X-ray results were compared between groups with bilateral and unilateral correction. Mean AOFAS score in these 2 groups after 12 months after surgery was 85,6±6,2 and 85,5±6,9 (p>0,05), mean intermetatarsal angle - 8,4±0,5° and 8,8±0,8° (p>0,05) respectively. No statistically significant difference between these two groups was found. Conclusion. A bigger surgical trauma in case of simultaneous bilateral correction neither worsens functional and x-ray results nor increases a complication rate.

Objective - to study the effect of tunnelization and apparatus hip decompression on the state of proximal femur growing plate. Material and methods. A pattern of changes in proximal femur growing plate of the affected and intact extremities was investigated in 46 children with III degree Perthes disease. The follow-up was 3 years. To unload the affected joint, an external fixator (most often, the Ilizarov apparatus) was placed on pelvic and femoral bones, which was used in a mode of non-articulating arthrodiastasis. The measurements of width of proximal femur growing zone were performed on pelvic bones rentgenograms in anteroposterior projection with internal hip rotation achieved with 1 meter focal length and their subsequent transfer to a digital format. Results. In the study group wire tunneling and apparatus fixation were shown not to result in growing plate locking, providing conditions for recovery of the shape and structure of the femoral head, which was accompanied by a slowdown in its width decrease in the affected extremity and led to the compliance of this parameter between the intact and affected extremities. No correlation was revealed between the degree of structural metaphyseal damage and the state of proximal growing zone.

Full-thickness rotator cuff tears - is abundant injury which leads to the expressed pain syndrome and functional violation of the top extremity. At making decision about necessary of surgery, MRI is the important source of information about the injury The purpose: to determine the qualitative and quantitative indicators of degenerative-dystrophic changes in muscular and tendinous parts of the rotator cuff. based on a combined MRI, arthroscopic and histological diagnostics of full-thickness rupture of shoulder cuff Methods: We have examined 28 patients with full-thickness rotator cuff tears. MRI of damaged joint to all patients before an operation was performed. Thereafter an arthroscopy was performed and intraoperative biopsy of the muscular and tendinous parts of the rotator cuff, with following histological examination. Results: It was found that at small full-thickness rotator cuff tears the intensity of degenerative changes in muscular and tendinous tissue was lower, so these tears are the most promising for all kinds of treatment. At medium and big tears intensity of degenerative changes in the tissues begins to prevail over productive inflammation and it limits to the ability of conservative treatment and increases the risk of unsuccessful outcomes of arthroscopic reconstruction. Conclusions: In this regard, it is necessary to search biological decisions, which complement the stage of arthroscopic reconstruction of the rotator cuff.

Comparative analysis of patient treatment results with extensive and deep posttraumatic defects of different segments of lower limbs has been done in this article. Early (n=71) and late (n=127) microsurgical reconstructive operations with using island flaps and free axial skin flaps have been performed to all these patients. According to authors, early microsurgical reconstructive operations have significant opportunities due to similar but later done operations. In particular, operative treatment makes necessary conditions for reliably more frequent using of less difficult operations with island flaps and creates statistically reliable reduce of additional operations demand. This treatment also provides the best long-term results and a more complete functional recovery of the damaged lower extremities in terms from two to six years.

Objective - based on the analysis of remote results of total hip arthroplasty in patients with complex deformities of the femur to compare the effectiveness of operations with standard cases and identify the factors that determine the surgery effectiveness. Material and methods. in Vreden clinic 73 patients with complex deformities of the femur underwent surgical treatment between 2001 and 2013 by various surgical interventions: arthroplasty without femoral osteotomy (23); arthroplasty accompanied by great trochanteric slide osteotomy or Paavilainen technigue (37), arthroplasty with femoral osteotomy below the lesser trochanter (13), including 4 - at the level of deformation, 4 - with double two-stage osteotomy and 5 - with one-stage double osteotomy. all patients were assessed with Harris scale before and after surgery. the results obtained in the course of the study data were processed using statistical methods, including correlation analysis using Pearson's coefficients and Gamma. Results. in assessing the long-term results the Harris hip score improved from a preoperative average of 40.2 (95% Ci 38.2 to 45.6) to 78.4 (95% Ci 76.7 to 83.5). the analysis of various factors influencing on operation efficiency showed that maximum results are achieved with good initial function and a small level of pain (Harris score of 40-45 points), residual femoral deformation should not exceed 5 degrees, the rotation center displacement - no more than 30 mm, the offset increasing - no more than 20 mm and of limb length increasing - no more than 25-30 mm. Conclusion. Hip arthroplasty in patients with coxarthrosis associated with complex femoral deformities is technically challenging, but the using the algorithm presented by authors allows achieve the best possible results.
Current principles and trends of using axial pattern flaps in reconstructive surgery of the extremities
Authors: Kutyanov D. I. , Rodomanova L. A.
Published: June 2017

On the basis of published data, we identified and analyzed current principles and trends of using axial pattern tissue complexes in patients with limb defects, depending on the nature and localization of the defect, and also objectives of reconstructive surgery. Today, there are three closely related trends. The most important one is to reduce injury caused by intervention; this results in using non-free island flaps instead of the widespread use of free perfused tissue complexes. The second trend is aimed at obtaining the most favorable functional results in treating defects of the covering structures relative to similar defects of bones and muscle-tendon units. The third trend is minimizing the negative aesthetic results.

Purpose: to evaluate correlation between generalized joint hypermobility, forefoot deformities and elasticity of the first ray of the foot. Material and methods. We examined 138 patients with complaints related with deformities at the forefoot level. During this study the medical history was obtained, the elasticity type of the feet was defined and the degree of motion of the medial metatarsal-cuneiform joint was evaluated. Forefoot elasticity was identified by bringing together the heads I and V metatarsal bones with fingers. If convergence occurred with little resistance, those feet were called hyperelastic. The convergence of the heads I and V metatarsal bones of the foot with an average type of elasticity occurred with resistance. It was impossible to converge the heads of I and V metatarsal bones. Due to the results of weight-bearing and non-weight bearing X-ray, analysis of the main radiographic angles of the foot was performed: between I and V metatarsal bones, between the first and second metatarsal bones and between the first metatarsal bone and proximal phalanx of the great toe. Calculation formula of the forefoot flatness index, showing the average ratios of basic radiographic angles of the foot on the x-ray images (weight-bearing and non-weight bearing) was created. An assessment of total joint hypermobility using Beighton scale and evaluation of first ray deformity using DuPont scale were performed. Statistical analysis of obtained data was performed, as a result of which significantly strong correlation between total joint hypermobility, forefoot elasticity and valgus deviation of the great toe were revealed. Results. 11% of the feet were hyperelastic. Calculation of the index of forefoot flatness showed that forefoot flatness wasn’t significant for a rigid foot - 5.6 %, for the feet with an average degree of mobility it was 6.0% and it was expressed for hypemobile feet - 12.3 %. Strong correlation relation between the forefeet mobility degree, the number of points on a DuPont scale and the degree of sagittal mobility of the medial metatarsal-cuneiform joint were revealed. Conclusion. Our study demonstrates that generalized joint hypermobility, horizontal and sagittal first ray mobility and forefoot deformities are directly proportional.
