Femoral Shaft Fracture After Hip Arthroplasty: A System for Classification and Treatment


ABSTRACT: Twenty-one consecutive cases of femoral shaft fracture after hip arthroplasty treated at the University of Illinois affiliated hospitals were reviewed. Adequate follow-up and radiographs were available for 19 patients. The length of follow-up after fracture ranged from 2 to 13 years, with a mean of 3.1 years. The time from index procedure to fracture averaged 2.6 years, with a range of 10 days to 11 years. The primary femoral stem was cemented in 11 hips  and cementless in 8 hips. Six patients were treated nonoperatively and 13 operatively. Three  had fracture fixation with retention of a well-fixed prosthesis and 10 had prosthetic revision. Cortical allograft was used in 5 cases. Sixteen of the 19 patients returned to their prefracture  level of function and ambulation. The factors important to treatment are fracture stability,  implant stability, and adequacy of bone stock. A classification system based on these factors  and recommendations for treatment are proposed.
