Abstract
Between 1982 and 1986, 56 femoral fractures associated with cementless total hip arthroplasty (THA) were evaluated and compared to a randomly selected cementless THA control group without fractures. Depending upon the femoral shaft location, these fractures were classified as Types I, II or III. There were 45 (80%) Type I, 9 (16%) Type II, and 2 (4%) Type III fractures. Patient evaluations were quantified using a modified d'Aubigne-Harris scoring system. Nonparametric statistical methodology was used for fracture and control group comparisons. Treatment protocols were divided into various modalities, depending upon fracture classification. Type I and Type II fractures have no long-term prognostic hazards associated with them (P greater than 0.1), while Type III fractures appear to have analogous clinical results (sample size was too small for statistical analysis).
