Modes of failure of hip hemiarthroplasty for femoral neck fracture.

Background: Hemiarthroplasty is a common treatment for displaced femoral neck fractures, but limited Canadian data are available about hemiarthroplasty failure. We evaluated the frequency and predictors of hemiarthroplasty failure in Manitoba.

Methods: In this retrospective multicentre province-wide study, billing and joint registry databases showed 4693 patients who had hemiarthroplasty for treatment of femoral neck fracture in Manitoba over an 11-year period (2005-2015), including 155 hips with subsequent reoperations (open or closed) for treatment of hemiarthroplasty failure.

Metatarsal Shaft Fracture with Associated Metatarsophalangeal Joint Dislocation.

Metatarsophalangeal joint dislocations of lesser toes are often seen in the setting of severe claw toes. Traumatic irreducible dislocations have been reported in rare cases following both low-energy and high-energy injuries to the forefoot. In this case report, I present a previously unreported association of a metatarsal shaft fracture with metatarsophalangeal joint dislocation of a lesser toe.

The cortical step sign fails to prevent malrotation of a nailed femoral shaft fracture: a case report.

Intramedullary nailing has become the treatment of choice for diaphyseal femur fractures. Malrotation is a well-recognized complication of femoral nailing. Various techniques including the cortical step sign (CSS) have been described to minimize iatrogenic rotational deformity during femoral nailing.

Double Hill-Sachs lesion: a report of two cases.

Hill-Sachs lesions are common after anterior dislocation of the shoulder. We present two cases of uncommon double Hill-Sachs lesions composed of a typical Hill-Sachs lesion and an atypical extra compression fracture with a rim of normal cartilage in between. Both patients had two anterior shoulder dislocations before surgery.
