Proximal femoral fractures are relatively common during total hip arthroplasty. The purposes of this study were to identify risk factors associated with femoral fractures and determine their effect on femoral stem survivorship. A total of 2551 hips were examined with up to 16 years of follow-up (mean, 6.8 years). Seventy-five percent of the stems were cemented. The incidence of proximal femoral fracture was 2.3% (59 hips). Risk factors associated with fractures include anterolateral approach, uncemented femoral fixation, and female sex (P <.01). Cerclage wiring was the most common treatment. After a fracture, femoral component survivorship was 95.8% for uncemented stems and 91.7% for cemented stems. In the absence of fracture, stem survivorship was 98.6% for cemented stems and 100% for circumferentially coated tapered titanium uncemented stems.
