Endoprostheses last longer than intramedullary devices in proximal femur metastases.
The proximal femur is the most common site of surgery for bone metastases, and stabilization may be achieved through intramedullary fixation (IMN) or endoprosthetic reconstruction (EPR). Intramedullary devices are less expensive, less invasive, and may yield improved function over endoprostheses. However, it is unclear which, if either, has any advantages. ⋯ Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Partial tibial nerve transfer to the tibialis anterior motor branch to treat peroneal nerve injury after knee trauma.
Injuries to the deep peroneal nerve result in tibialis anterior muscle paralysis and associated loss of ankle dorsiflexion. Nerve grafting of peroneal nerve injuries has led to poor function; therefore, tendon transfers and ankle-foot orthotics have been the standard treatment for foot drop. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyA short tapered stem reduces intraoperative complications in primary total hip arthroplasty.
While short-stem design is not a new concept, interest has surged with increasing utilization of less invasive techniques. Short stems are easier to insert through small incisions. Reliable long-term results including functional improvement, pain relief, and implant survival have been reported with standard tapered stems, but will a short taper perform as well? ⋯ Level III, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Multicenter Study Comparative StudySimilar outcomes for nail versus plate fixation of three-part proximal humeral fractures.
There is a lack of consensus regarding optimal surgical management of displaced and unstable three-part proximal humeral fractures. ⋯ Level II, therapeutic study (prospective comparative study). See the Guidelines for Authors for a complete description of levels of evidence.

Intraarticular hip disease is commonly acknowledged as a cause of ipsilateral knee pain. However, this is based primarily on observational rather than high-quality evidence-based studies, and it is unclear whether ipsilateral knee pain improves when hip disease has been treated. ⋯ Level III, diagnostic study. See Guidelines for Authors for a complete description of levels of evidence.
