Meta AnalysisTuberosity healing after reverse shoulder arthroplasty for complex proximal humeral fractures in elderly patients-does it improve outcomes? A systematic review and meta-analysis.
Reverse shoulder arthroplasty (RSA) is being increasingly used for complex, displaced fractures of the proximal humerus in older patients. Anatomic tuberosity healing in RSA has been recognized to restore better shoulder function. We compared the reported clinical and functional outcomes of RSA in proximal humeral fractures with and without tuberosity healing. ⋯ The RSA group with healed greater tuberosity showed better range of motion, especially forward flexion and external rotation and Constant scores, compared with the nonhealed greater tuberosity group. Tuberosity healing may influence overall shoulder function after RSA for proximal humeral fractures in the elderly, and this needs verification with future prospective studies.

Reverse shoulder arthroplasty for acute fractures in the elderly: is it worth reattaching the tuberosities?
Reverse Shoulder Arthroplasty (RSA) may be indicated in displaced proximal humerus fractures in elderly patients. We hypothesized that tuberosity fixation and healing around the prosthesis would result in better outcomes and patient satisfaction. ⋯ Despite the advanced age of the patients, tuberosity reattachment and use of bone graft results in a high rate of tuberosity healing. Tuberosity reconstruction and healing in reverse shoulder arthroplasty for fractures improves active forward elevation, external rotation, and patient satisfaction.

Fragility of randomized clinical trials of treatment of clavicular fractures.
Statistical significance, as reported by the P value, has traditionally been the most commonly reported way to determine whether a difference exists between clinical interventions. Unfortunately, P values alone confer little about the robustness of a study's conclusions. An emerging metric, the fragility index (FI), helps to address this challenge by quantifying the number of events per outcome group that would need to be reversed to the alternative outcome in order to raise the P value above the 0.05 threshold. ⋯ The median FI reported in the recent literature on clavicular fractures is only 2. The FI is a useful metric to analyze the robustness of study conclusions that should complement other methods of critical data evaluation, including the P value or effect sizes. Future efforts are needed to increase institutional collaboration and patient recruitment to strengthen the robustness of RCT conclusions, especially in the realm of clavicular fracture management.
