Comparative StudySurgical treatment for avulsion injuries of the humeral lesser tuberosity apophysis in adolescents.
There is little published information regarding avulsion fractures of the humeral lesser tuberosity in adolescents, and no consensus exists on optimal treatment. The purpose of this study was to investigate the demographics, injury mechanisms, and results of operative treatment of lesser tuberosity avulsion fractures in skeletally immature patients. ⋯ Humeral lesser tuberosity avulsion fractures do occur in adolescents, typically from high-energy sports injuries. Careful physical examination and magnetic resonance imaging (MRI) evaluation aid in achieving a timely diagnosis. Surgical reduction and suture fixation is safe and effective in restoring subscapularis function and return to sports, even in cases of delayed treatment. Full recovery of shoulder external rotation may not be seen until six months postoperatively.

Randomized Controlled Trial Comparative StudyThe effect of weekly risedronate on periprosthetic bone resorption following total hip arthroplasty: a randomized, double-blind, placebo-controlled trial.
Bone loss leading to late-occurring periprosthetic femoral fracture is a mode of failure in cementless total hip arthroplasty. The aim of this trial was to investigate the effect of a bisphosphonate, risedronate, on femoral periprosthetic bone resorption following total hip arthroplasty in patients with osteoarthritis of the hip. ⋯ Risedronate taken once weekly for six months following total hip arthroplasty was effective in reducing periprosthetic bone resorption around an uncemented femoral stem up to one year after surgery but had no discernible effect on implant migration or clinical outcome. Future studies of bisphosphonate treatment following total hip arthroplasty should focus on clinically relevant end points such as the risks of fracture and revision arthroplasty.

Comparative StudyFixation of the coronoid process in elbow fracture-dislocations.
Terrible triad injuries consist of a posterior dislocation of the elbow, a coronoid fracture, and a radial head fracture. The coronoid plays a pivotal role as an anterior buttress, yet the optimal management of the coronoid fracture remains unknown. We hypothesize that suture lasso fixation of the coronoid fracture leads to fewer complications and improved outcomes compared with screw or suture anchor fixation techniques. ⋯ For terrible triad injuries, greater stability with fewer complications was achieved with use of the suture lasso technique for coronoid fracture fixation.
