Authors: Demekaa Umbur , Demekaa Bridget
Published: June 2021

The purpose of this study is to investigate determinants of users’ level of satisfactions with circulation policies in academic libraries in the North Central Zone of Nigeria. A descriptive survey design was adopted for the study. The population comprised all the undergraduate registered users of the university libraries in the zone. The stratified random sampling technique was used to draw a sample of 600 registered library users for the study from four university libraries in the zone. A total of one research question were raised and one hypothesis formulated to guide the study. A self-constructed questionnaire entitled: “Determinants of Gender and Users’ level of Satisfaction with Circulation Policies in Academic Libraries Questionnaire (DGULSCPALQ)” was the instrument used for data collection. A reliability of the instrument was carried out using 100 registered users of the Delta State University Library, Abraka over a time lag of two weeks in order to determine its content and construct reliability. Data generated were analysed using Pearson’s Product Moment Correlation, which yielded an r of 0.80, which was considered adequate for the instrument. The data collected were analysed by using mean and standard deviation to answer the research question, while z-test statistical technique was used to test the formulated hypothesis at 0.05 level of significance. Findings revealed that Federal universities had moderate mean in the level of satisfaction with library opening hours than State owned Universities; The study also revealed that male library users had a high mean in the level of satisfaction with library opening hours on week days and a high mean score in level of satisfaction with the total number of cards issued for borrowing of items than female, there were no significant differences between federal and state universities in user’s level of satisfaction with library holdings, borrowers’ cards, loan period, fines and reservation. There was no significant difference between federal and state owned universities except in user’s level of satisfaction with library opening hours. Also, there was no significant difference between male and female users except in users’ level of satisfaction with library loan periods. Finally, it was recommended that public university libraries in the North Central Zone of Nigeria should extend their opening hours on Sundays to make the users more satisfied with opening hours on that day; that the libraries should ensure that their circulation policies on fines for damaged and lost borrowed materials should reflect the present realities/cost of the items.

The Mobile Learning Enhances the Quality of Learning: A Study
Authors: Vijayakumar S. , Ramesh Babu V.
Published: June 2021

The use of mobile phones and other portable devices is beginning to have an impact on how learning takes place in many disciplines and contexts, including language learning. Learners who are not dependent on access to fixed computers can engage in activities that relate more closely to their current surroundings, sometimes crossing the border between formal and informal learning. This creates the potential for significant change in teaching and learning practices. Taking the broader field of mobile learning as the setting within which developments in mobile-assisted language learning may be understood, the paper argues that an emphasis on mobility can lead to new perspectives and practices. With increased popular access to information and knowledge anywhere, anytime, the role of education, perhaps especially formal education, is challenged and the relationships between education, society, and technology are now more dynamic than ever .The present paper was based on secondary sources of data highlighting of concept, Features, values , Challenges and advantages of M-learning.

Authors: Pal Falguni , Hatua Sudip Ranjan
Published: June 2021

The study reveals that non-academic libraries are gradually becoming more important with specialized needs of the users. It also makes a call for library professionals to nurture the skillful activities with concern and commitments. However innovative ventures of professionalism could be effective to satisfy greater demands in a better way. Unfortunately professional courses don’t have any reflection in their curricula to cope with the services of non-academic libraries. LIS schools are not that much aware of designing of their syllabi at per with the demand of non-academic libraries. Enough scope is there to introduce specialized courses for multi-modal service generation via corporate librarianship, digital scholarship, technical writings, and cooperative information delivery – thus make the relevance of the study. An attempt has been made to evaluate the present scenario of non-academic libraries and to understand the professional requirements; so as to build-up the proficiency (competency, skill, expertise) in this sector by revitalizing the LIS courses in an Indian context.

Impact of Overemphasis of Technology on Information Literacy Program: A Study
Authors: Singh Bibhuti Kumar
Published: June 2021

The Literature on Information Literacy often assume that there is some inherent relation between Information Literacy and Information Technology and the concept of information literacy has been developed to meet the challenges generated by Information Technology in the form of Information Explosion. Such assumption also reflected in Information Literacy programs which are offered in the academic institutions. This paper argues that the concept of Information Literacy has been in use before the Information Explosion and it should be treated as an ability to understand the intricacies of information, as a tool for lifelong learning and a skill to use information effectively rather than giving more emphasis on technology,which can only make a computer literate who may be expert in using computer, but may not be able to evaluate and use the available information effectively.
Maker Space: A Beginner Way to Imparting Library for Adani Institute of Infrastructure Engineering
Authors: Makwana Prakash
Published: June 2021

Adani Institute of Infrastructure Engineering (AIIE) is established to equip the students to become modern-day engineers and managers primarily for the infrastructure and allied sectors. The Institute is presently conducting three Bachelor Programmes in Engineering. 1. BE- Civil & Infrastructure Engineering, 2.BE-Electrical Engineering, 3.BE -Information & Communication Technology. Adani Institute of Infrastructure Library embarked on a change journey in 2008 for services in support of the education. The concept for creating a maker space for engineering students within the library to foster activity -based learning. Maker spaces are over just places to create things; a maker space may be a physical location wherever people gather to share resources and knowledge, work on projects, network, and build. The NMC Horizon Report: 2015 higher education the paper examines the awareness and importance of library maker spaces. A questionnaire was used for collection of data. Around 50 questionnaires were distributed among the students. A total of 30 stuffed in questionnaires were selected for analysis of the data. While there is a push to include maker spaces in universities, very little is understood regarding the expertise of establishing maker spaces on engineering campuses. Typically, these maker spaces contain 3D printers and laser cutters, and offer facilities to conduct work, personal and collaborative projects. The idea for creating a maker space for engineering library is promotional activity-based learning. Maker spaces are over just places to make things; a maker space may be a physical location wherever people gather to share resources and knowledge, work practical projects, network, and build. Libraries that have lengthy been substitutable with peace and tranquillity are currently thought of as a part in which there have to be a stability between quiet surroundings and social dynamic mood. The intention of this study is to observe the importance of maker space of engineering libraries that is tremendously needed in technological advancements and alteration of ancient systems with new ones. This analysis consists of reviewing the domestic samples, conforming examples to library maker space and inspecting numerous libraries over a duration of time. The outcomes of this find out about indicate that generally, modern libraries have fewer areas for paper books and publications and individual study, instead, bigger spaces are committed to locations for cluster studies and the use of computer and maker space etc. This trade has influenced the function of the library space and maker space.
Vanishing Rice Fields - The Quest for Wealth and Belief in (Post-)Socialist Vietnam
Authors: Wehrli Angelica Laura Lucia
Published: June 2021

The book delineates how the quest for wealth and belief manifests itself in contemporary Vietnam. Based on multi-local and longitudinal ethnographic research, the author examines how wealth is pursued by household members and entrepreneurs. The quest for belief is brought into relief through inquiry into how norms and values have been re-evaluated, altered, subverted or restored. Focusing on the taboo topic of female feticide, The study elucidates why some parents ultimately decide to commit feticide, and why others, especially entrepreneurs, refrain from it. The case of the entrepreneurs shows a possible way out of the "vicious circle" that leads to female feticide and perpetuates gender inequality.

Collaborative writing ‘betwixt and between’ sits jaggedly against traditional regimes of authorship
Authors: Crimmins Gail , Black Ali , Jones Janice K , Loch Sarah , Impiccini Julianne
Published: June 2021

In the context of academic financialisation where writing is ‘repurposed’ as an outcome designed to maximise financial profit, and to resist the pressure to be ‘careless’ (Lynch 2010) ‘ideal functionaries’ (Pereira 2012), we – a group of five women academics – come together to share stories of our accrued wisdom about living in the afternoon of our lives. We also share our creative writing and theorising about collaborative writing processes in papers, chapters, and conference presentations. As we do so, we encounter a conflict between our practice of inter-personal collaboration and the traditions and pressures of academic authorship where we are expected to publish in a vertical hierarchy of

(first author,

nameless et al.s,

We therefore reflect on the paradoxes and tensions involved in collaborative writing within the academy. In particular, we explore how co-operative practice congruent with the philosophical framework of new materialism sits jaggedly against an academic culture of individualism, surveillance, audit, and the pressure for academics to (be seen to) publish. We offer no conclusion or easy resolution, but like Socratic ‘gadflies’ we seek to trouble the structural impediments to collaborative writing in the academy
Exegesis and artefact as a woven work: Problems of examination
Authors: Krauth Nigel
Published: June 2021

The idea that the exegesis and the creative work are kept separate in a research degree submission dates back to early non-traditional doctorates in the Australian context. But, while an increasing number of research publications worldwide use fragmented structures and strategies which blend scholarly and non-scholarly approaches, what are the chances of honours, masters and doctoral students succeeding under examination with submissions that weave together exegetical and creative components? This paper examines the expectations universities have for their creative writing research submissions, and the strategies examiners may use in examining exegeses woven into the subject artefact they talk about. Exploring how examiners might read woven works, this paper surveys, especially, reader-response theory as developed by Wolfgang Iser and others.
Highways, activism and solastalgia: Poetic responses to Roe 8
Authors: Bartlett Alison , Chinna Nandi
Published: June 2021

This paper is a response to activism in the summer of 2016/17 when bulldozers pushed a 5km highway footprint, known as the Roe 8 extension, through urban wetlands and woodlands in Perth’s southern suburbs. We argue that the impact of the community campaign to halt Roe 8, and the clearing of this land evoked a form of cultural mourning and loss that can be thought of as solastalgia (Albrecht 2008). As an increasingly common experience in the Anthropocene, we are interested in how solastalgia can be expressed. In our need to comprehend and articulate solastalgia, we propose that a poetic response to the Roe 8 bulldozing offers a complex and intense a form of mourning which is not restricted to that summer of activism but connects with broader experiences of environmental loss. Poetry has long been a form of writing that unsettles, that gives voice to the un-namable, to the currents and sinews that run beneath the surface of an often alienating and incomprehensible society. As part of a tradition of activist poetics, this article includes poetry written in response to the physical affect of witnessing radical ecological destruction.

Authors: Morales Deborah Cecilia Navarro , Palenque Eduardo , Justiniano Jorge Deheza
Published: June 2021

Back somersault is a basic element of gymnastics; its performance is strongly influenced by the take-off phase. The present work aimed to study how hip extension in the take-off of the tucked back somersault influences the velocity of rotation and the height of t h e somersault. To this end, we recorded a total of 60 somersaults by 4 gymnasts (i.e., 15 somersaults each). There were three groups of somersaults based on the instructions that were given to the gymnasts: no specific instruction, somersault as high as possible and rotate as fast as possible. The records were then analyzed in order to quantify the following variables: maximal height of the mass center and maximal body angular velocity during somersault, the hip angle and the knee angle at the take-off. Gymnasts seemed to be inclined to bend their knees rather than extend their hips in order to carry out the instruction.
La diffusion des cours universitaires en direct : retour sur une ancienne nouveauté
Authors: Peltier Claire
Published: June 2021

La diffusion des cours en direct est une tendance qui se dessine depuis quelques années dans l’enseignement supérieur et a constitué une solution de choix pour la mise à distance des cours universitaires durant la pandémie de COVID-19. Présentée comme une innovation, la diffusion des cours en direct est pourtant loin d’être une nouveauté. Cet article se propose d’aborder l’usage pédagogique de la captation vidéo à des fins de transmission et de diffusion des savoirs, sous l’angle de l’histoire de la formation à distance et des technologies éducatives, ainsi que sous celui de l’innovation pédagogique. L’exemple de la mise en place, à travers trois cours pilotes, d’un dispositif de diffusion des cours en direct à l’Université de Genève sera analysé à l’aune des changements potentiels engendrés par l’introduction d’une nouveauté dans la routine des pratiques.
Pérennité et mutations en formation à distance à l’université : Retour sur le vécu des vingt années d’existence du campus numérique FORSE
Authors: Verquin Savarieau Béatrice , Simonian Stéphane , Béziat Jacques
Published: June 2021

Les appels à projets « campus numériques français » au début des années 2000 soulignent une volonté politique d’impulser le développement de la formation à distance en enseignement supérieur. Après un bref retour historique sur les faits marquants de cette époque, les auteurs reviennent sur le destin singulier du premier campus numérique francophone en Sciences de l’éducation FORSE (Formations et ressources en Sciences de l'éducation), qui fêtera ses vingt ans en 2021. Cette vision rétroactive conduit à retenir tout d’abord l’idée d’un passage de la notion de « paysage », qui implique une approche verticale du changement en éducation et en formation, à celle « d’écosystème » du numérique, dans lequel dominent des interrelations fortes et constantes entre l’ensemble des membres d’un groupe projet et le politique. À partir de ce cadre d’analyse, les auteurs explorent divers aspects de l’intégration de la formation à distance jusqu’à l’assimilation dans les pratiques ordinaires universitaires : le rapport entre l’humain et les objets techniques; les relations asymétriques et les intérêts partagés entre acteurs à des postes complémentaires qui favorisent une collaboration fructueuse; enfin le développement des activités technopédagogiques qui se jouent également dans l’expérimentation et la recherche-action. Ainsi, l’importance de la prise en compte du réel de l’activité et de ses dimensions contextuelles comme conditions essentielles des rapports stabilisés entre les pratiques humaines et les objets techniques.

PENGARUH TEMPERATUR PREHEAT TERHADAP DISTORSI DAN STRUKTUR MIKRO SAMBUNGAN LAS TAK SEJENIS ANTARA BAJA KARBON ASTM A36 DAN BAJA TAHAN KARAT AUSTENITIK AISI 304 MENGGUNAKAN GMAW
Authors: Wicaksono Danny , Ilman Mochammad Noer
Published: June 2021

Sambungan las pada umumnya adalah titik lemah dari suatu struktur dan sering menjadi lokasi kegagalan pada pengelasan logam tidak sejenis. Berbagai upaya telah dilakukan untuk meningkatkan kualitas dan performa dari sambungan las, salah satunya adalah pemanasan awal (preheat). Penelitian ini bertujuan mempelajari pengaruh temperatur preheat terhadap sambungan las logam tak sejenis antara baja paduan rendah dan baja tahan karat austenitik. Proses pengelasan dilakukan menggunakan las busur logamgas atau gas metal arc welding (GMAW) dengan elektrode ER70s-6 dan selama proses pengelasan dilakukan preheat pada temperatur 100oC, 150oC, dan 200oC. Temperatur selama proses pengelasan diukur menggunakan termokopel pada jarak 10 mm dari garis las. Setelah proses pengelasan dilakukan, pengukuran distorsi dilakukan menggunakan dial indicator. Pengamatan struktur mikro dilakukan pada daerah terpengaruh panas (HAZ), daerah las, dan daerah logam induk dari masing-masing pelat yang dilas menggunakan mikroskop optik. Berdasarkan hasil pengukuran siklus termal, dapat disimpulkan bahwa peningkatan temperatur preheat meningkatkan temperatur puncak dan memperlambat laju pendinginan las. Perubahan siklus termal ini berpengaruh terhadap struktur mikro. Berdasarkan hasil pengukuran distorsi, pelat yang dilas mengalai penurunan distorsi pada arah longitudinal dan transversal terhadap garis las seiring dengan meningkatnya temperatur preheat
Bailar en San Antonio

Recuerdo claramente la primera vez que tuve oportunidad de conversar con el Negro Valdivia. Fue en su casa de Mayu Sumaj una tarde esplendorosa de mayo. Fuimos con Gabriel Bendersky y charlamos largamente bajos los árboles del patio. De esa charla recuerdo dos cosas que se fueron haciendo más y más importantes para mí. Por una parte, esa fue la primera vez que escuchaba hablar del Encuentro de San Antonio. Gabriel y yo formamos parte de un equipo de investigación que venía estudiando las músicas populares desde la perspectiva de la sociología de la cultura. En esos días andábamos indagando sobre el circuito de las peñas, y preguntándonos por el tipo de música que prefería la gente que asistía y por las razones de esa preferencia. En esa búsqueda muchas personas nos habían hablado de Valdivia por diversas razones, entre ellas por ser durante mucho tiempo el maestro de ceremonias de las peñas del Dúo Coplanacu. Pero la charla con el Negro nos fue llevando de a poco para el lado del Encuentro. Un poco sorprendido, y ansiosamente, le empecé a preguntar por las características que tenía y el Negro, con ese hablar pausado que lo caracteriza me dijo: “tenés que ir, no te lo puedo explicar. Tenés que participar para ver cómo es”. En ese momento estaba muy lejos de entender lo que me estaba diciendo. Y estaba lejos de saber la importancia que tenía esa idea de participar, en la lógica del Encuentro

Differential diagnosis of acute traumatic hip pain in the elderly
Authors: Hampton Matthew , Stevens Richard , Highland Adrian , Gibson Richard , Davies Mark B
Published: June 2021

Elderly patients who present with an inability to weight bear following a fall, with normal radiographs, should be appropriately investigated to rule out an occult hip fracture (OHF). We aim to identify both the range and incidence of the differential diagnosis of acute traumatic hip pain in a large series of patients investigated for OHF.

A retrospective analysis of consecutive patients investigated for an OHF with magnetic resonance imaging (MRI) was performed. Dedicated musculo- skeletal radiologists reported the MRI scans. All diagnoses including hip fractures, other fractures and soft tissue injuries were recorded. Case notes were reviewed for all patients to identify subsequent complications, management and outcomes.

A total of 157 patients fulfilled the inclusion criteria. 52 (33%) patients had a fracture of the proximal femur. The majority of patients with proximal femoral fractures required surgical intervention. 9 patients who had fractures of the greater trochanter of the femur without fracture extension across the femoral neck were managed non-operatively.

40 (25%) patients had fractures of the pelvis, with a combined pubic rami and sacral fracture occurring frequently. The most common diagnosis was a soft tissue injury alone that was seen in 60 (38%) patients imaged. Injuries to the gluteal muscle group, iliopsaos complex and trochanteric bursa were most prevalent. All patients with soft tissue injuries or fractures of the pelvis were successfully managed non-operatively.

This study highlights a wide range of differential diagnoses in elderly patients presenting with acute traumatic hip pain. The proximal femur was frac- tured in 33% of patients imaged for OHFs in our series. The most common diagnosis was a soft tissue injury around the hip and pelvis ; these injuries can be successfully managed without surgery.
Dual mobility versus unipolar total hip arthroplasty for neck of femur fractures: a single centre study
Authors: Sadozai Zain , Limb Richard , Awais Bokhari Syed , Ng Aaron , Bhamra Manjit
Published: June 2021

Current national guidelines (NICE) recommends that all medically fit, independently-mobile patients without cognitive impairment receive a total hip arTHAoplasty(THA) for displaced intracapsular neck of femur (NOF) fractures. Dislocation is a concern(2-10%). Dual mobility cups have been suggested to address this complication. Our study sets out to compare dislocation rates between dual mobility cups versus unipolar cups.

We performed a retrospective single centre multiple surgeon study of all THAs performed for NOFs between January 2012 and May 2018. A total of 322 total hip replacements (127 dual mobility and 195 unipolar ; Age range of patients, 29 to 91, mean 70 years) were identified for analysis using a database. Data was obtained from electronic patient records and radiographs.

12 patients sustained a dislocation of their THA out of our 322 patients. Of these, 10 dislocations occurred in the unipolar group (5.13%). From the dual mobility cups, 2 had dislocations(1.57%), both with a 28mm head. Both of these dislocations were in alcohol dependent patients with increased susceptibility to falls. Statistical analysis of our data was performed using chi-squared test (p value = 0.0723)

In ‘Getting It Right First Time’ (GIRFT), the authors recommend that all patients that sustain a NOF fracture meeting the criteria of a THA to be offered a dual mobility acetabular cup to reduce the risk of dislocation. The cost of the dual mobility acetabular cup is offset from the cost of overall revision surgery. Limitations of our study are its retrospective nature and selection bias.

The concern of extensive fracturing and bone damage during implant removal has been reported for ingrowing stems, in particular in extended porous coated stems, potentially impeding successful re- implantation of a femoral revision implant and con- sequently debilitating patients for life.

The aim of the present study is to describe this particular complication and comparing the occurrence in porous coated and hydroxyapatite (HA) coated femoral implants.

62 consecutive revision hip replacements were per- formed between January 2010 and December 2016 at a single academic institution. Only revisions of a primary total hip replacement were included. All surgeries were performed by the same senior surgeon. Clinical follow-up involved examination with the Harris hip score (HHS) at 2 years post surgical intervention. Fracture occurrence and severity were compared between groups by means of the Vancouver classification for intraoperative fractures.

Overall, significant higher rates of fracturing were observed in the porous coated group (81.8%, p<0.05) compared to the HA coated group (43.5%, p<0.05). Of these fractures, the majority (72,7%) were B3 fractures. There was a significant difference between the mean HHS in the porous-coated group versus the group with HA coating (mean Harris Hip Scores of 68,45 vs 86,17, p = .004).

Surgeons have to be wary with implanting porous coated stems in primary hip arthroplasty, especially in younger patients who have a high likelihood of future revision surgery, due to the catastrophic peri-operative fractures associated with the removal of these stems.

Plain radiographic assessment of primary total hip arthroplasty following surgery remains to be the commonest radiological assessment. The current paper, studies the accuracy and concordance between observers reviewing these radiographs.

A prospective radiographic and medical note review of ten patients who underwent total hip replacement for primary osteoarthritis, with a mean age of 69 years. Early and 6 weeks postoperative x-rays were assessed for hip profile and version profile using computer aided design (CAD) by two observers on two different occasions. The observers were Orthopaedic surgeons who perform arthroplasty of the hip. The results were analyzed statistically.

Dimensions, including Femoral offset, medial offset and ilioischial offset showed a high degree of inter- film and intra-film correlation, with inter-class correlation (ICC) over 0.8. Except of the intra-film correlation of ilioischial offset measured on the post- operative films (p=0.067) by the first rater, all the intra and inter film correlation were significantly over the benchmark of 0.6. In terms of stem alignment, cup inclination and cup version, the intra-film correlation by rater n°2 ranges from 0.574 to 0.975 and were significantly over the benchmark of 0.6, except in the case of cup inclination measured on the 6 th? week follow-up ; meanwhile the intra-film correlation by rater n°1 ranges from 0.581 to 0.819 and none were significantly over the benchmark of 0.6.

The inter-rater reliability and inter-film correlation showed a dichotomy of results among different dimensions of the measurement. Dimensions of femo- ral offset, medial offset and ilioischial offset showed a substantial degree of reliability in terms of inter-rater reliability, inter-film correlation, and intra-rater/film reliability.

Purpose : distal femoral periprosthetic fracture (DFPPF) is a serious complication following total knee arthroplasty (TKA). Recently, treatment of DFPPF with distal femoral arthroplasty (DFA) has gained popularity because of its posited benefits for both patients and the medical system. Short-term follow-up trials investigating DFA have demonstrated acceptable results with regards to function, pain relief and lower postoperative complications than ORIF in elderly patients. The purpose of the current study was to evaluate a consecutive series of DFPPF treated with DFA, with a minimum 2- year follow-up.

Methods : We performed a retrospective study asses- sing the outcomes of distal femoral arthroplasty (DFA) for patients diagnosed with DFPPF.

Results : Twenty patients were identified. The mean age of patients was 76.3 (SD, 9.41), the average time from the fracture to revision surgery was 6.7 days (SD, 11.35), The average operative time was 93.5 minutes (SD,16.6). The average follow-up time was 50.15 months (SD, 20.87). During this time, two patients (10%) had complications. One patient experienced a knee dislocation and the second patient had recurrent periprosthetic infections. At final follow up, the mean knee society score was 86.25 (SD, 9.44), the mean Forgotten joint score was 62.16(SD, 23.45) and 93.7 percent of patients were ambulatory.

Conclusion : DFA following DFPPF is associated with high success rates and provides patients with the opportunity for return of function in a safe and reliable manner.

Published: June 2021

The purpose is to determine if ligament reconstruction with tendon interposition (LRTI) is a recommendable salvage option for failed total joint prosthesis of the first carpometacarpal joint.

Twenty-two patients in our database met the in- clusion criteria for this retrospective study, with at least 6 months follow-up. Fourteen participated and were invited for a clinical examination and asked to fill out two questionnaires. They were evaluated for pain (VAS), impairment (NHS), disability (Quick DASH), opposition (Kapandji test) and grip strength (hydraulic dynamometer). Results of the questionnaires were compared to a cohort study of primary LRTI’s. Kapandji test and grip strength were compared to the contralateral side.

Compared to primary LRTI’s, revision surgery showed mild deterioration of impairment and disability. The average VAS score was 2.9 out of 10. Twelve patients mentioned a sense of strength loss, which could be quantified with the dynamometer : a mean of 15.1 kg (operated thumb) versus 20.5 kg (contralateral). There was a relatively small decline of opposition with Kapandji 8.6 versus 9.9. The overall satisfaction was good for 8 patients, fair for 3 and poor for the remaining 3 (mainly based on strength loss). One patient needed a second revision.

Failed first carpometacarpal joint replacement can be salvaged by ligament reconstruction with tendon interposition, providing an acceptable functional outcome in 79% of cases studied. However, compared to the functional outcome of primary LRTI’s, mild aggravation of impairment and disability should be taken into account.

Children with attention deficit hyperactivity disorder (ADHD) have an increased risk of sustaining fractures during their preschool years. Supracondylar humerus fractures (SHFs) comprise the majority of fracture surgeries in the pediatric age range. We hypothesized that ADHD symptoms would be present in children with SHFs, and this characteristic trauma may be associated with an ADHD diagnosis. Thus, we compared the ADHD symptoms of children with and without SHFs. Further, we compared the trauma characteristics, gender, proneness to injury, and presence of prior trauma history of children diagnosed with and without ADHD. We recruited 41 children who were admitted to emergency service with an SHF and 41 age- and gender-matched children without a fracture history. A semi-structured diagnostic inter- view and a Swanson Nolan Pelham questionnaire were used to obtain data about ADHD symptoms. A clinical intake form was utilized for further clinical data. ADHD symptoms were significantly higher in the fracture group ; male gender, parent- reported proneness to injury, and prior history of trauma were significantly associated with ADHD. Orthopedic surgeons may provide early detection of ADHD by using screening tools or asking questions to caregivers and making referrals when needed. This may lead to prevention of further injuries.
