Aims We aimed to quantify the relative contributions of the medial femoral circumflex artery (MFCA) and lateral femoral circumflex artery (LFCA) to the arterial supply of the head and neck of the femur. Materials and Methods We acquired ten cadaveric pelvises. In each of these, one hip was randomly assigned as experimental and the other as a matched control. The MFCA and LFCA were cannulated bilaterally. The hips were designated LFCA-experimental or MFCA-experimental and underwent quantitative MRI using a 2 mm slice thickness before and after injection of MRI-contrast diluted 3:1 with saline (15 ml Gd-DTPA) into either the LFCA or MFCA. The contralateral control hips had 15 ml of contrast solution injected into the root of each artery. Next, the MFCA and LFCA were injected with a mixture of polyurethane and barium sulfate (33%) and their extra-and intra-arterial course identified by CT imaging and dissection. Results The MFCA made a greater contribution than the LFCA to the vascularity of the femoral head (MFCA 82%, LFCA 18%) and neck (MFCA 67%, LFCA 33%). However, the LFCA supplied 48% of the anteroinferior femoral neck overall. Conclusion This study clearly shows that the MFCA is the major arterial supply to the femoral head and neck. Despite this, the LFCA supplies almost half the anteroinferior aspect of the femoral neck. Cite this article: Bone Joint J 2016;98-B:1582–8.

Published: December 2016

AimsThe aim of the study was to develop a quantitative scoring system to predict whether a large-to-massive rotator cuff tear was arthroscopically reparable prior to surgery.Patients and MethodsWe conducted a retrospective review of the pre-operative MR imaging and surgical records of 87 patients (87 shoulders) who underwent arthroscopic repair of a large-to-massive rotator cuff tear. Patients were divided into two groups, based on the surgical outcome of the repair. Of the 87 patients, 53 underwent complete repair (Group I) and 34 an incomplete repair (Group II). Pre-operative MR images were reviewed to quantify several variables. Between-group differences were evaluated and multiple logistic regression analysis was used to calculate the predictive value of significant variables. The reparability index (RI) was constructed using the odds ratios of significant variables and a receiver operating characteristic curve analysis performed to identify the optimal RI cutoff to differentiate between the two groups.ResultsThe following variables were identified as independent predictors of arthroscopic reparability: the size of the defect with medial-lateral diameter (cutoff, 4.2 cm) and anterior-posterior diameter (cutoff, 3.7cm); Patte’s grade of muscle atrophy (cutoff, grade 3) and Goutallier grade of fatty degeneration (cutoff, grade 3). An RI cutoff value of 2.5 provided the highest differentiation between groups I and II, with an area under the curve of 0.964, and a sensitivity of 73.5% and specificity of 96.2%.ConclusionThe RI developed in our study may prove to be an efficient clinical scoring system to predict whether a large-to-massive rotator cuff tear is arthroscopically reparable.

Published: December 2016

Aims To evaluate whether an ultra-low-dose CT protocol can diagnose selected limb fractures as well as conventional CT (C-CT). Patients and Methods We prospectively studied 40 consecutive patients with a limb fracture in whom a CT scan was indicated. These were scanned using an ultra-low-dose CT Reduced Effective Dose Using Computed Tomography In Orthopaedic Injury (REDUCTION) protocol. Studies from 16 selected cases were compared with 16 C-CT scans matched for age, gender and type of fracture. Studies were assessed for diagnosis and image quality. Descriptive and reliability statistics were calculated. The total effective radiation dose for each scanned site was compared. Results The mean estimated effective dose (ED) for the REDUCTION protocol was 0.03 milliSieverts (mSv) and 0.43 mSv (p < 0.005) for C-CT. The sensitivity (Sn), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) of the REDUCTION protocol to detect fractures were 0.98, 0.89, 0.98 and 0.89 respectively when two occult fractures were excluded. Inter- and intra-observer reliability for diagnosis using the REDUCTION protocol (κ = 0.75, κ = 0.71) were similar to those of C-CT (κ = 0.85, κ = 0.82). Using the REDUCTION protocol, 3D CT reconstructions were equivalent in quality and diagnostic information to those generated by C-CT (κ = 0.87, κ = 0.94). Conclusion With a near 14-fold reduction in estimated ED compared with C-CT, the REDUCTION protocol reduces the amount of CT radiation substantially without significant diagnostic decay. It produces images that appear to be comparable with those of C-CT for evaluating fractures of the limbs. Cite this article: Bone Joint J 2016;98-B:1668-73.
Restoration of the centre of rotation in primary total hip arthroplasty
Authors: Meermans G. , Doorn J. Van , Kats J-J. 
Published: December 2016

AimsOne goal of total hip arthroplasty is to restore normal hip anatomy. The aim of this study was to compare displacement of the centre of rotation (COR) using a standard reaming technique with a technique in which the acetabulum was reamed immediately peripherally and referenced off the rim.Patients and MethodsIn the first cohort the acetabulum was reamed to the floor followed by sequentially larger reamers. In the second cohort the acetabulum was only reamed peripherally, starting with a reamer the same size as the native femoral head. Anteroposterior pelvic radiographs were analysed for acetabular floor depth and vertical and horizontal position of the COR.ResultsHorizontally, the mean medial displacement of the COR was 0.8 mm (standard deviation (sd) 1.4) in the peripheral remaing group and 5.0 mm (sd 3.30) in the standard reaming group (p < 0.001). Vertically, the mean superior displacement of the COR was 0.7 mm (sd 1.3) in the peripheral reaming group and 3.7 mm (sd 2.6) in the standard reaming group (p < 0.001). In the standard reaming group, there was a strong correlation between the pre-operative acetabular floor depth and displacement of the COR (p < 0.001).ConclusionReaming the acetabulum to the floor can lead to significant displacement of the COR medially and superiorly. This displacement is related to the pre-operative acetabular floor depth and cannot always be compensated by using a high offset stem. Cite this article: Bone Joint J 2016;98-B:1597–603.

Published: December 2016

AimsRisk of revision following total knee arthroplasty (TKA) is higher in patients under 55 years, but little data are reported regarding non-revision outcomes. This study aims to identify predictors of dissatisfaction in these patients.Patients and MethodsWe prospectively assessed 177 TKAs (157 consecutive patients, 99 women, mean age 50 years; 17 to 54) from 2008 to 2013. Age, gender, implant, indication, body mass index (BMI), social deprivation, range of movement, Kellgren-Lawrence (KL) grade of osteoarthritis (OA) and prior knee surgery were recorded. Pre- and post-operative Oxford Knee Score (OKS) as well as Short Form-12 physical (PCS) and mental component scores were obtained. Post-operative range of movement, complications and satisfaction were measured at one year.ResultsOverall, 44 patients with 44 TKAs (24.9%) under 55 years of age were unsure or dissatisfied with their knee. Significant predictors of dissatisfaction on univariate analysis included: KL grade 1/2 OA (59% dissatisfied), poor pre-operative OKS, complications, poor improvements in PCS and OKS and indication (primary OA 19% dissatisfied, previous meniscectomy 41%, multiply operated 42%, other surgery 29%, BMI > 40 kg/m231%, post-traumatic OA 45%, and inflammatory arthropathy 5%). Poor pre-operative OKS, poor improvement in OKS and post-operative stiffness independently predicted dissatisfaction on multivariate analysis.ConclusionPatients receiving TKA younger than 55 years old should be informed about the increased risks of dissatisfaction. Offering TKA in KL 1/2 is questionable, with a dissatisfaction rate of 59%. Cite this article: Bone Joint J 2016;98-B:1625–34.
The pathology and management of lesser toe deformities
Authors: Malhotra Karan , Davda Kinner , Singh Dishan 
Published: December 2016

Deformities of the lesser toes are common and can be associated with significant morbidity. These deformities are often multiple, and numerous treatment strategies have been described in the literature. The goal of surgical treatment is to improve symptoms by restoring alignment and function, and avoiding recurrence. In order to achieve this, it is essential for the treating surgeon to understand the normal anatomy and pathology of the various deformities. There is a paucity of prospective studies and randomised-controlled trials assessing the efficacy of specific interventions. We describe the normal anatomy and biomechanics of the lesser toes, and the pathology of commonly adult deformities. The rationale behind various treatment strategies is discussed and the results of published literature presented. Algorithms for the management of lesser toe deformities based on current literature are proposed. Cite this article: Malhotra K, Davda K, Singh D.

Anterior cruciate ligament reconstruction: principles of treatment
Authors: Paschos Nikolaos K. , Howell Stephen M. 
Published: December 2016

Anterior cruciate ligament (ACL) reconstruction is one of the most common procedures in sports medicine. Several areas of controversy exist in ACL tear management which have engaged surgeons and researchers in debates towards identifying an ideal approach for these patients. This instructional review discusses the principles of ACL reconstruction in an attempt to provide guidelines and initiate a critical thinking approach on the most common areas of controversy regarding ACL reconstruction. Using high-level evidence from the literature, as presented in randomised controlled trials, systematic reviews, and meta-analyses, operative versus conservative treatment, timing of surgery, and rehabilitation are discussed. Also, the advantages and disadvantages of the most common types of autografts, such as patellar tendon and hamstrings as well as allografts are presented. Key considerations for the anatomical, histological, biomechanical and clinical data (‘IDEAL’) graft positioning are reviewed.Cite this article: Paschos NK, Howell SM.

A New Closed Form Approximation for BER for Optical Wireless Systems in Weak Atmospheric Turbulence
Authors: Kaushik Rahul , Khandelwal Vineet , Jain R. C. 
Published: December 2016

Abstract
Weak atmospheric turbulence condition in an optical wireless communication (OWC) is captured by log-normal distribution. The analytical evaluation of average bit error rate (BER) of an OWC system under weak turbulence is intractable as it involves the statistical averaging of Gaussian Q-function over log-normal distribution. In this paper, a simple closed form approximation for BER of OWC system under weak turbulence is given. Computation of BER for various modulation schemes is carried out using proposed expression. The results obtained using proposed expression compare favorably with those obtained using Gauss-Hermite quadrature approximation and Monte Carlo Simulations.
Yiddish for Spies, or the Secret History of Jewish Literature, Lemberg 1814
Authors: Dynes Ofer 
Published: December 2016

AbstractThis article has two goals: first, it aims to solve a mystery in Yiddish studies by identifying the previously unknown author of one of the earliest Eastern European modern literary texts in Yiddish, and reconstructing the historical context in which he wrote the text. Second, it will show how this archival-biographical discovery sheds new light on the history of Eastern European Jews during the Napoleonic Wars (1799–1815) as well as on the rise of Haskalah literature. Finally, as the title of this article suggests, I will argue that there was a direct link between narration and denunciation, between the Austrian imperial interest in collecting insider information about the Jews and the turn to writing literature in Jewish languages.

Abstract
There are many factors that affect the well-being and health of employees and the productivity of organisations. The aim of this study was to determine the impact of the Metal Age training programme (MA®) on the well-being of office workers, including investigation of work ability, the stress-causing factors and role of leadership. The study was carried out using questions from four international questionnaires about stress, leadership, and work ability. The intervention group had a training course between the surveys using the ME® method. Several employee stress-causing factors were identified: bad relationship with their workmates was mentioned by 94% of workers; competitive and strenuous atmosphere — by more than 80%; psychological violence or bullying at the workplace by more than 80%, and more than 75% of employee’s could not relax after work. Wellness and microclimate in the workplaces were on a relatively high level: the average rating of seven Kiva questions was 7.5. The respondent attitude after ME® did not change significantly. Latvian office workers displayed moderate and good work ability (Work Ability Index, WAI 34.5–38.6). The best work ability was shown in the age group from 20 to 49 (WAI 34.8–39.4); work ability decreased with age. The best correlation was observed between Work Ability Index and “get into situations, that invoke negative feelings” (r = 0.26) and “carrying out ongoing tasks because of other intervening or more urgent matters” (r = −0.24). After ME® the reaction to some stress-causing factors was improved.
Constraints on aspectual complement ellipsis. The view from Romanian
Authors: Nicolae Alexandru 
Published: December 2016

AbstractRomanian aspectual complement ellipsis reveals the fact competing selection frames of verbs filter out potentially well-formed instances of deletion, this situation revealing yet another constraint on ellipsis with verbal licensers. Situations of this sort were dealt with in previous generative models by assuming “global derivational constraints” no longer available in the current minimalist architecture of the grammar. After delimiting the domain of ellipsis with verbal licensers in Romanian (the passive auxiliary
Culture and the Working Class: Lee Hall’s Billy Elliot and The Pitmen Painters
Authors: Paul Ronald 
Published: December 2016

Abstract
In his work as a playwright, Lee Hall not only explores dramatically the troubled relationship between culture and the working class in Britain. He also seeks to challenge the stereotyped images of the working class in the media as being feckless, inarticulate and incapable of engaging in any cultural production on their own terms. In this paper I examine the ways in which this encounter between the working class and ‘high art’ is depicted in the film Billy Elliot (2000) and the play The Pitmen Painters (2008), both written by Lee Hall. In these portrayals of a working-class boy’s struggle to become a ballet dancer and of the collective efforts of a group of coal miners to express themselves as fine artists, I discuss how far Hall has succeeded in subverting received working-class stereotypes and what are the broader political and aesthetic implications of his cultural depictions of these coal-mining communities.
Imaginación geopolítica y modernismo desde las crónicas parisinas de Rubén Darío
Authors: Delgado Arbuto Leonel 
Published: December 2016

La base argumental de este artículo es que existe una preocupación geopolítica en el modernismo hispanoamericano, y que en algunas crónicas de Rubén Darío esta preocupación es abordada en su carácter global y capitalista, enfatizando el destino decadente de la cultura detradición greco-latina. Asimismo, esto muestra una línea de desarrollo dentro de la obra de Darío que se remonta a su visión de la modernidad chilena en Azul (“La canción del oro”). Se considera, además, la coyuntura crítica actual de los estudios sobre Darío en los que se acentúa el carácter transatlántico e hispanista de su obra por sobre la inscripción latinoamericanista que dominó a partir de los años 1960, ante todo por medio de la obra de Ángel Rama.

Published: December 2016

ABSTRACTThe main purpose of this research was to establish the effectiveness of the V844 corrosion inhibitor for seawater on various metallic materials: carbon steel, aluminum and copper alloy at different concentrations via colloid formation. The changes in both physical and chemical properties of seawater, including pH, total hardness, alkalinity, total dissolved solids (TDS) and conductivity at different concentrations of V844 were assessed, too. The test procedure involves dissolving the V844 corrosion inhibitor powder provided by Magna International Private Limited in seawater to obtain a stock solution of 4% V844 in seawater, which was further diluted to obtain the remaining concentrations. The analysis of parameters begun when various metal species, polished beforehand, were placed into the solutions. The analysis was observed over a period of 26 days and a total of 9 sets of readings were obtained. From our observation and analysis, it was concluded that the inhibitor worked best at 0.05% concentration for carbon steel.
Reactive oxygen species in BCR-ABL1-expressing cells – relevance to chronic myeloid leukemia
Authors: Antoszewska-Smith Joanna , Pawlowska Elzbieta , Błasiak Janusz 
Published: December 2016

Chronic myeloid leukemia (CML) results from the t(9;22) reciprocal chromosomal translocation producing the BCR-ABL1 gene, conferring growth and proliferation advantages in the CML cells. CML progresses from chronic, often syndrome-free, to blast phase, fatal if not treated. Although the involvement of BCR-ABL1 in some signaling pathways is considered as the cause of CML, the mechanisms resulting in its progression are not completely known. However, BCR-ABL1 stimulates the production of reactive oxygen species (ROS), which levels increase with CML progression and induce BCR-ABL1 self-mutagenesis. Introducing imatinib and other tyrosine kinase inhibitors (TKIs) to CML therapy radically improved its outcome, but TKIs-resistance became an emerging problem. TKI-resistance can be associated with even higher ROS production than in TKI-sensitive cells. Therefore, ROS-induced self-mutagenesis of BCR-ABL1 can be crucial for CML progression and TKI resistance and in this way should be taken into account in therapeutic strategies. As a continuous production of ROS by BCR-ABL1 would lead to its self-destruction and death of CML cells, there must be mechanisms controlling this phenomenon. These can be dependent on DNA repair, which is modulated by BCR-ABL1 and can be different in CML stem and progenitor cells. Altogether, the mechanisms of the involvement of BCR-ABL1 in ROS signaling can be involved in CML progression and TKI-resistance and warrant further study.
