Use of the Giliberty bipolar endoprosthesis in femoral neck fractures

Thirty-three patients (average age, 78.9 years) with femoral neck fractures were treated with Giliberty bipolar prosthesis inserted through a posterior approach. There were four procedure-related deaths. Nine patients required readmission for treatment of complications including five patients with a dislocated prosthesis and two with a disassembled prosthesis. The average hospital stay was 30.2 days. Varus position of the cup is a possible cause of component disassembly. This prosthesis is probably unsuitable in the elderly patient with a femoral neck fracture.
