Meta AnalysisAbove- or below-elbow casts for distal third forearm fractures in children? A meta-analysis of the literature.
Fractures of the distal third forearm are common fractures in childhood. Most of these fractures can be treated non-operatively by means of closed reduction and immobilization. The purpose of this meta-analysis is to investigate whether above- or below-elbow cast should be considered the first-choice for conservative treatment. ⋯ Due to heterogeneity, the trials are not fully compared. Based on the presented meta-analysis, we conclude that BEC is not inferior to AEC so that this is a valid treatment option for distal third forearm fractures.

Rate of avascular necrosis following proximal humerus fractures treated with a lateral locking plate and endosteal implant.
Treatment of displaced proximal humerus fractures remains challenging. The introduction of locking plates has renewed interest in treating these fractures with joint-preserving techniques rather than hemiarthroplasty, but high complication rates are still reported. Avascular necrosis is not solely dependent on the initial fracture pattern, but can also result from intraoperative and postoperative vascular insults. ⋯ Use of the anterolateral approach and endosteal augment of a lateral locking plate can minimize avascular necrosis following proximal humerus fracture.

Cross-linked ultra-high-molecular weight polyethylene liner and ceramic femoral head in total hip arthroplasty: a prospective study at 5 years follow-up.
Recent data indicate that enhanced wear resistance can be obtained with new cross-linked ultra-high-molecular weight polyethylene (CL-UHMWPE) liners, in comparison with previous-generation liners. The current prospective, cohort study was undertaken to analyse whether the use of a new CL-UHMWPE (Rexpol) results in a lower wear rate than ultra-high-molecular weight polyethylene (UHMWPE) in a group of similar patients undergoing total hip arthroplasty (THA). This study provides the first clinical data with this particular CL-UHMWPE. ⋯ The use of CL-UHMWPE significantly reduced the risk of polyethylene wear in patients undergoing THA with biconical threaded cups and ceramic femoral heads. Further follow-up is needed to determine how this will influence long-term outcomes.

Case ReportsInsufficiency femoral intertrochanteric fractures associated with greater trochanteric avulsion fractures.
Insufficiency fractures are often overlooked, particularly when associated with greater trochanteric avulsion fractures. Here, we report magnetic resonance imaging (MRI) findings of insufficiency femoral intertrochanteric fractures associated with greater trochanteric avulsion fractures treated by internal fixation. We identified 8 patients (3 men and 5 women; age range, 58-92 years old). ⋯ There were no complications regarding the operation itself. Insufficiency femoral intertrochanteric fractures associated with greater trochanteric avulsion fractures were often overlooked. We successfully treated these fractures by internal fixation.
