Aims We compared implant and patient survival following intraoperative periprosthetic femoral fractures (IOPFFs) during primary total hip arthroplasty (THA) with matched controls. Patients and Methods This retrospective cohort study compared 4831 hips with IOPFF and 48 154 propensity score matched primary THAs without IOPFF implanted between 2004 and 2016, which had been recorded on a national joint registry. Implant and patient survival rates were compared between groups using Cox regression. Results Ten-year stem survival was worse in the IOPFF group (p < 0.001). Risk of revision for aseptic loosening increased 7.2-fold following shaft fracture and almost 2.8-fold after trochanteric fracture (p < 0.001). Risk of periprosthetic fracture of the femur revision increased 4.3-fold following calcar-crack and 3.6-fold after trochanteric fracture (p < 0.01). Risk of instability revision was 3.6-fold after trochanteric fracture and 2.4-fold after calcar crack (p < 0.001). Risk of 90-day mortality following IOPFF without revision was 1.7-fold and 4.0-fold after IOPFF with early revision surgery versus uncomplicated THA (p < 0.001). Conclusion IOPFF increases risk of stem revision and mortality up to ten years following surgery. The risk of revision depends on IOPFF subtype and mortality risk increases with subsequent revision surgery. Surgeons should carefully diagnose and treat IOPFF to minimize fracture progression and implant failure. Cite this article: Bone Joint J 2019;101-B:1199–1208

Aims The aim of this study was to conduct the largest low contact stress (LCS) retrieval study to elucidate the failure mechanisms of the Porocoat and Duofix femoral component. The latter design was voluntarily recalled by the manufacturer. Materials and Methods Uncemented LCS explants were divided into three groups: Duofix, Porocoat, and mixed. Demographics, polyethylene wear, tissue ingrowth, and metallurgical analyses were performed. Results In 104 implants, a decrease in the odds of loosening and an increase in metallosis and tissue staining in the Duofix group relative to Porocoat group was detected (p = 0.028). There was an increased presence of embedded metallic debris in the Duofix group (p < 0.001). Decreased tissue ingrowth was associated with the Duofix surface (p < 0.001). The attached beads had reduced microhardness, indicative of adverse thermal processing, which resulted in bead shedding, particulate debris, and metallosis. Conclusion Hydroxyapatite coating of the LCS femoral component produced unexpected results and led to its recall. The root cause was likely a combination of retained alumina grit and a reduction in bead microhardness (mechanical strength) resulting in increased particle debris, metallosis, and early revision. The Duofix LCS femoral component was not equivalent to the Porocoat version despite its approval through the Food and Drug Administration (FDA) 510(k) equivalance approval process. Regulation of the introduction of modified existing devices needs to be improved and the Duofix LCS should have been considered to be a new device for which equivalence had not been demonstrated at the point of introduction.

Published: September 2019

Aims To compare complication-related reoperation rates following primary arthroplasty for proximal humerus fractures (PHFs) versus secondary arthroplasty for failed open reduction and internal fixation (ORIF). Patients and Methods We identified patients aged 50 years and over, who sustained a PHF between 2004 and 2015, from linkable datasets. We used intervention codes to identify patients treated with initial ORIF or arthroplasty, and those treated with ORIF who returned for revision arthroplasty within two years. We used multilevel logistic regression to compare reoperations between groups. Results We identified 1624 patients who underwent initial arthroplasty for PHF, and 98 patients who underwent secondary arthroplasty following failed ORIF. In total, 72 patients (4.4%) in the primary arthroplasty group had a reoperation within two years following arthroplasty, compared with 19 patients (19.4%) in the revision arthroplasty group. This difference was significantly different (p < 0.001) after covariable adjustment. Conclusion The number of reoperations following arthroplasty for failed ORIF of PHF is significantly higher compared with primary arthroplasty. This suggests that primary arthroplasty may be a better choice for patients whose prognostic factors suggest a high reoperation rate following ORIF. Prospective clinical studies are required to confirm these findings. Cite this article: Bone Joint J 2019;101-B:1272–1279

Published: September 2019

AimsThe primary aim of this study was to develop a reliable, effective radiological score to assess the healing of humeral shaft fractures, the Radiographic Union Score for HUmeral fractures (RUSHU). The secondary aim was to assess whether the six-week RUSHU was predictive of nonunion at six months after the injury.Patients and MethodsInitially, 20 patients with radiographs six weeks following a humeral shaft fracture were selected at random from a trauma database and scored by three observers, based on the Radiographic Union Scale for Tibial fractures system. After refinement of the RUSHU criteria, a second group of 60 patients with radiographs six weeks after injury, 40 with fractures that united and 20 with fractures that developed nonunion, were scored by two blinded observers.ResultsAfter refinement, the interobserver intraclass correlation coefficient (ICC) was 0.79 (95% confidence interval (CI) 0.67 to 0.87), indicating substantial agreement. At six weeks after injury, patients whose fractures united had a significantly higher median score than those who developed nonunion (10 vs 7; p < 0.001). A receiver operating characteristic curve determined that a RUSHU cut-off of < 8 was predictive of nonunion (area under the curve = 0.84, 95% CI 0.74 to 0.94). The sensitivity was 75% and specificity 80% with a positive predictive value (PPV) of 65% and a negative predictive value of 86%. Patients with a RUSHU < 8 (n = 23) were more likely to develop nonunion than those with a RUSHU ≥ 8 (n = 37, odds ratio 12.0, 95% CI 3.4 to 42.9). Based on a PPV of 65%, if all patients with a RUSHU < 8 underwent fixation, the number of procedures needed to avoid one nonunion would be 1.5.ConclusionThe RUSHU is reliable and effective in identifying patients at risk of nonunion of a humeral shaft fracture at six weeks after injury. This tool requires external validation but could potentially reduce the morbidity associated with delayed treatment of an established nonunion. Cite this article: Bone Joint J 2019;101-B:1300–1306

Cessar a reprodução dos atuais problemas sociais, ambientais e econômicos exige uma transformação da maneira de abordar a educação e a vida, o que evidencia a importância da Educação para a Sustentabilidade (EpS). Ao analisar a formação de profissionais de gestão, a importância da EpS fica ainda mais manifesta, considerando os impactos das decisões destes profissionais sobre o meio ambiente e sociedade. Assim, para que objetivos da EpS sejam alcançados, novas propostas pedagógicas são necessárias, a EpS encontra oportunidades nas abordagens de aprendizagem de epistemologia construtivista, como a Aprendizagem Experiencial (AE). Assim, a presente pesquisa tem como objetivo analisar a capacidade contributiva da Aprendizagem Experiencial para a Educação para a sustentabilidade em uma iniciativa interdisciplinar desenvolvida no ensino de gestão. A partir da realização de entrevistas e aplicação de questionário, levantou-se dados a respeito de iniciativa interdisciplinar, composta por duas disciplinas (Projeto Interdisciplinar 1 e 2) e sua relação com a AE. Os resultados indicam que ao adotar a AE como pano de fundo para o desenvolvimento da iniciativa é possível alcançar os resultados almejados pela EpS, podendo contribuir com o desenvolvimento discente no que tange ao pensamento crítico, visão sistêmica, perspectiva de futuro, entre outros.
Coaching the Power Clean: A Constraints-Led Approach

Published: September 2019

ABSTRACT
Traditionally, strength and conditioning coaches have used explicit instructions when changing movement behavior. Recent work has questioned the efficacy of this approach. Whether explicit instruction is best for facilitating movement change is discussed along with an alternative approach. A brief review of traditional coaching methods is undertaken, highlighting differences between the traditional “coach-centered approach” and an “athlete-centered, constraints-led approach.” The constraints-led approach is applied to coaching the power clean. This provides an example of how strength and conditioning practitioners may approach the coaching of movement using methods that align with contemporary coaching as well as skill acquisition theory.

It has long been thought that severe chronic pain conditions, such as complex regional pain syndrome (CRPS), are not only associated with, but even maintained by a reorganization of the somatotopic representation of the affected limb in primary somatosensory cortex (S1). This notion has driven treatments that aim to restore S1 representations in CRPS patients, such as sensory discrimination training and mirror therapy. However, this notion is based on both indirect and incomplete evidence obtained with imaging methods with low spatial resolution. Here, we used fMRI to characterize the S1 representation of the affected and unaffected hand in humans (of either sex) with unilateral CRPS. The cortical area, location, and geometry of the S1 representation of the CRPS hand were largely comparable with those of both the unaffected hand and healthy controls. We found no differential relation between affected versus unaffected hand map measures and clinical measures (pain severity, upper limb disability, disease duration). Thus, if any map reorganization occurs, it does not appear to be directly related to pain and disease severity. These findings compel us to reconsider the cortical mechanisms underlying CRPS and the rationale for interventions that aim to “restore” somatotopic representations to treat pain.SIGNIFICANCE STATEMENTThis study shows that the spatial map of the fingers in somatosensory cortex is largely preserved in chronic complex regional pain syndrome (CRPS). These findings challenge the treatment rationale for restoring somatotopic representations in complex regional pain syndrome patients.

Published: September 2019

Mata pelajaran Antropologi di SMA tergabung dalam kelompok IPS (Ilmu Pengetahuan Sosial). Meskipun telah menjadi salah satu bagian mata pelajaran di SMA, Â keberadaan mata pelajaran Antropologi tidak pernah berdiri menjadi mata pelajaran sendiri, melainkan menjadi bagian mata pelajaran Sejarah dan Sosiologi. Tujuan artikel ini adalah untuk membahas bagaimanakah keberadaan mata pelajaran antropologi di SMA setelah merger ini dan bagaimana kendala-kendala pembelajaran antropologi di SMA. Metode penelitian yang digunakan adalah pendekatan kualitatif, pengumpulan data dilakukan dengan observasi, wawancara dan dokumentasi. Hasil penelitian menunjukkan bahwa dalam tahun terakhir yang sibuk dengan penyempurnaan kurikulum, mata pelajaran Antropologi justru semakin termarjinalisasi. Antropologi hanya menjadi sub-bahasan Â saja dalam mata pelajaran lain. Antropologi juga semakin dianggap kurang penting, padahal antropologi sangat penting dalam konteks masyarakat multikultural seperti Indonesia. Hal tersebut menyebabkan terjadinya kendala-kendala dalam proses pembelajaran di antaranya kendala struktural, kultural, dan keterbatasan sumber daya manusia.Anthropology in high school subjects is incorporated in IPS batch (Social Sciences). Although it has become one of the subjects at the high school, Anthropology is a not an independent subject. Â It isonly part of History and Sociology subjects. The objective of this article is to study the existence of anthropological subjects in high school. The research method used is Â qualitative approach, data collection was done by observation, interview and documentation. The results show that over the years of curriculum improvement, anthropology subjects are becoming more and more marginalised. Â Anthropology is only a sub topics of other school subjects. Many regards anthropology no longer important though in fact anthropology is an important subject in a multicultural society like Indonesia. This maginalization of anthropology subject leads to other constraints in the learning process, which include structural, cultural, and human resource constraints.

Keberadaan Kelenteng Ban Eng Bio yang terletak di tengah-tengah pemukiman penduduk Tionghoa dan non Tionghoa yang berbeda agama banyak membawa pengaruh. Salah satunya adalah dalam pelaksanaan ritual yang dilakukan di Kelenteng. Pelaksanaan ritual di Kelenteng tidak hanya melibatkan masyarakat Tionghoa yang berada di sekitar Kelenteng, tetapi juga masyarakat non Tionghoa yang berada di sekitarnya. Tujuan penelitian ini adalah mengkaji bagaimana pelaksanaan ritual yang dilakukan di Kelenteng Ban Eng Bio dalam membentuk solidaritas sosial, serta bagaimana partisipasi masyarakat Tionghoa dan non Tionghoa sekitar Kelenteng dalam ritual di Kelenteng Ban Eng Bio terhadap upaya pengembangan integrasi sosial. Metode penelitian menggunakan pendekatan kualitatif. Pengumpulan data dilakukan dengan observasi, wawancara dan dokumentasi. Hasil penelitian menunjukkan bahwa pelaksanaan ritual yang dilakukan di Kelenteng melibatkan masyarakat Tionghoa dan non Tionghoa baik sebagai pendukung, pengaman maupun penonton, sehingga terjadi suatu solidaritas sosial diantara mereka. Partisipasi masyarakat non Tionghoa dan Tionghoa dapat meningkatkan integrasi sosial masyarakat khususnya di Desa Adiwerna. Keterlibatan masyarakat sekitar kelenteng khususnya masyarakat non Tionghoa dalam ritual masyarakat Tionghoa diupayakan tidak mengarah pada terjadinya percampuran agama yang dianggap bisa menumbuhkan masalah baru dalam hubungan antar umat beragama.The location of Ban Eng Bio temple in the middle of the Chinese and non-Chinese residences , with different religious backgrounds, brings many influences. One of them is the influence on the rituals performed in the temple. The implementation of the ritual in the temple does not only involve the Chinese community around the temple, but also non-Chinese communities in the surrounding areas. The objective of this reasearch is to study how rituals performed at the Ban Eng Bio templeÂ and the participation of non-Chinese and Chinese communities around the temple forms solidarity and social integration. The methods of research is a qualitative approach and data was collected through observation, interview and documentation. The research reveals that the rituals done in the temple involve non-Chinese and Chinese communities either as supporters, workers, or viewers, resulting in the strengthening of social solidarity among them. The participation of non-Chinese and Chinese society also improves the social integration of people, especially in the VillageÂ of Adiwerna. The involvement of communities around the temples, especially non-Chinese people in Chinese society ritual does not lead into the mixing of religion because it can grow a new problem in inter-religious relations.
