OBJECTIVES: To predict the final result of intertrochanteric osteotomy.
MATERIALS AND METHODS: 56 hips in 53 patients after intertrochanteric osteotomy without any change in neck-shaft angle were enrolled into the analysis. 26 hips with a good result of intertrochanteric osteotomy were included into A group and 26 hips with a poor result were included into B group. The follow up was 5 to 11 years. Such preoperative parameters as: age and body weight of patients, severity of arthritis, sphericity of the head, joint space width, center-edge angle, pain severity, walking capacity, range of motion- were analyzed in both groups of patients. Survival of the hips was estimated with a Kaplan-Meyer survival curve.
RESULTS: At last follow up 27 hips (26 patients) were converted into hip prosthesis. The mean operative age of the patients in group A was 37.8 years and in group B 43.4 years. The severity of hip arthritis was similar in both groups of patients. Regular spherical head was found in 10 hips of group A and in 12 of B group. The center-edge angle was 15 degrees in group A and 18 degrees in group B. The joint space width was 2.6 mm in group A, and 2.5 mm in B group. Walking capacity, pain severity, range of motion of the affected hip was very similar in both groups of patients. Patients of group B had hip prosthesis already implanted 2.8 years after osteotomy.
CONCLUSIONS: No statistically significant difference was found between analyzed preoperative parameters in patients with good and poor results of intertrochanteric osteotomy. The final result of intertrochanteric osteotomy is not predictable.
