Intrinsic and extrinsic risk factors for nonunion after nonoperative treatment of midshaft clavicle fractures.
The optimal treatment of midshaft clavicle fractures remains controversial. Nonunion is usually considered to be an uncommon complication following a nonoperatively treated clavicle fracture. ⋯ Level III, case-control study.

Clinical TrialTitanium-titanium modular neck for primary THA. Result of a prospective series of 170 cemented THA with a minimum follow-up of 5 years.
Although they have been in use since the end of the 1980s, modular titanium neck components are associated with a risk of wear or fracture, and their safety has recently become a subject of debate and has never been evaluated in a consecutive series of patients. The goal of this study was to evaluate: revision-free survival of these implants after a minimum follow-up of 5 years; clinical and radiographic results; and the potential complications associated with the use of modular titanium neck components. ⋯ IV: prospective, non-comparative study.

Evaluation of a new baseplate in reverse total shoulder arthroplasty - comparison of biomechanical testing of stability with roentgenological follow up criteria.
To minimize notching problem associated with reversed prostheses, inferior positioning of base plate is recommended. This reduces the risk of notching, but does not eliminate it completely. Both polyethylene/PE-induced osteolysis and implant-to-bone or implant-to-implant contact may still occur, contributing to the risk of screw-breakage and resulting long-term failure. Therefore, the stability and integration of a newly developed base plate without inferior screw and inversion of bearing materials was investigated. ⋯ Level III, case-control study.

Critical analysis of olecranon fracture management by pre-contoured locking plates.
Fractures of the proximal ulna are rare and usually managed surgically. Strong fixation of the harware is essential to obtain good outcomes. We report our experience with pre-contoured locking plate fixation of complex olecranon fractures and present a critical appraisal of the outcomes. ⋯ Level IV, retrospective study.

The Asia proximal femoral nail antirotation versus the standard proximal femoral antirotation nail for unstable intertrochanteric fractures in elderly Chinese patients.
The best options of internal fixation for unstable intertrochanteric fractures in elderly Chinese patients remain controversial. The Asia proximal femoral nail antirotation (PFNA-II) was specifically designed for Asian patients, which could be more effective than the regular proximal femoral nail antirotation (PFNA). Compared to PFNA, whether PFNA-II is associated with shorter operative time and lower rates of complications is unknown. ⋯ Level III, case control study.
