Multicenter StudyAre there risk factors for complications of perforator-based propeller flaps for lower-extremity reconstruction?
Conventional pedicled flaps for soft tissue reconstruction of lower extremities have shortcomings, including donor-site morbidity, restricted arc of rotation, and poor cosmetic results. Propeller flaps offer several potential advantages, including no need for microvascular anastomosis and low impact on donor sites, but their drawbacks have not been fully characterized. ⋯ Level IV, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.

The effect of resident participation on short-term outcomes after orthopaedic surgery.
The influence of resident involvement on short-term outcomes after orthopaedic surgery is mostly unknown. ⋯ Level II, prognostic study. See the Instructions for Authors for a complete description of levels of evidence.

Sonication of antibiotic spacers predicts failure during two-stage revision for prosthetic knee and hip infections.
Periprosthetic joint infection is a leading cause of failure after two-stage reimplantation. One cause of relapse may be persistent subclinical infection. Difficulty exists in detecting biofilm-forming infections. Sonication disrupts biofilm and has led to higher rates of positive intraoperative cultures. ⋯ Level III, diagnostic study. See the Instructions for Authors for a complete description of levels of evidence.

Comparative StudyRadial head reconstruction in elbow fracture-dislocation: monopolar or bipolar prosthesis?
Monopolar and bipolar radial head prosthetic arthroplasties have been used successfully to treat elbow fracture-dislocation with unsalvageable radial head fractures. The relative stability of these two designs in different clinical situations is a topic of ongoing investigation. ⋯ The data from our cadaveric model support the use of either implant type in terrible triad injuries if the collateral ligaments are intact or reconstructed.

Heterotopic ossification of the elbow treated with surgical resection: risk factors, bony ankylosis, and complications.
Heterotopic ossification is the most common extrinsic cause of elbow contracture and may lead to clinically important stiffness, and rarely, complete bony ankylosis. Surgery sometimes is performed to treat this problem, and published reports differ regarding the factors that are associated with success or failure after this operation and whether the procedure is effective for patients with elbow ankylosis. ⋯ Level IV, therapeutic study. See the Instructions for Authors for a complete description of levels of evidence.
