Rotatory malunion following antegrade intramedullary femoral nailing for femoral shaft fractures: incidence and risk factors.

Design: Retrospective study.

Setting: Level I academic Trauma Center.

Patient Selection Criteria: Adult patients with femoral shaft fractures in which a bilateral computed-tomography (CT) scan of both femurs was performed, with a two years minimal follow-up.

Femoral malrotation from diaphyseal fractures results in changes in patellofemoral alignment and higher patellofemoral stress from a finite element model study.

Background: Malrotation of the femur is a frequent complication in the management of a diaphyseal fracture. It is often responsible for pain and adverse functional results. Among these complications, contact stress effects on the patellofemoral joint are recognized as predictive factors of impaired results.

Early intraprosthetic dislocation of a total hip replacement with dual mobility socket: clinical presentation and update review.

Intraprosthetic dislocation is a rare complication in dual mobility hip prostheses, which usually occurs after the third postoperative year due to wear of the polyethylene retentive rim. We report a rare and non-described case of a patient who presented disassembly of the polyethylene insert from his dual mobility socket at nine postoperative months, secondary to several reduction attempts of a posterior dislocation of his prosthesis.
