PURPOSE: To analyze the results of surgical treatment for pathological fractures at the proximal femur. MATERIALS AND METHODS: Nineteen patients with a pathological fracture were included. The mean age was 65.7 years old. The patients comprised 8 males and 11 females. Primary tumors, types of pathological fractures, surgical procedures, and postoperative complications were recorded. Musculoskeletal Tumor Society (MSTS) functional score was used for functional evaluation. A Kaplan-Meier survival analysis was used to determine survival rate. RESULTS: The primary malignancies were 6 cases of breast cancer, 3 cases of lung cancer, 3 cases of renal cell carcinoma, 2 cases of cholangiocarcinoma, 2 cases of hepatocellular carcinoma, 1 case of esophageal cancer, 1 case of colon cancer, and 1 case of ovarian cancer. Pathological fractures included 8 cases of pertrochanteric fractures and 11 cases of subtrochanteric fractures. Intramedullary nailing was performed in 10 cases, and joint replacement surgery was performed in 9 cases. Postoperative complications included local recurrence in 1 case, infection in 1 case, and nail breakage in 1 case. The mean postoperative MSTS score was 21. The mean survival period was 10.6 months. Patient survival rates were 42.1% after 6 months, 26.3% after 12 months, and 10.5% after 24 months. CONCLUSION: Surgical treatment of pathological fractures at the proximal femur provided early ambulation, and excellent pain relief. The surgery was well tolerated emotionally. Surgery is necessary for improving the quality of life in such patients; however, more cases of pathological fractures in these regions should be subjected to detailed analysis.

BACKGROUND: We evaluated the clinical and radiologic results of impacted femoral neck fractures treated with multiple pinning and determined the influence of the progression of impaction at the fracture site on clinical outcome. METHODS: There were 34 patients with a mean age of 65.5 years. The mean follow-up period was 3.4 years. Progression of fracture site impaction was measured using an articulo-trochanteric distance index and the percentage decrease in the articulo-trochanteric distance index between follow-up intervals. The failure of treatment was clarified as non-union and avascular necrosis. Other characteristics of the patients, including mean waiting time for surgery, preoperative Singh index score, and body mass index, were also measured to evaluate the influence on the clinical outcome of surgery. RESULTS: There were 6 fractures which were not treated successfully (3 non-union, 8.8% and 3 avascular necrosis, 8.8%). The mean percentage decrease of the articulo-trochanteric distance index within the first 6 weeks after surgery was 4.5% in the successful group and 25.1% in the failure group (p < 0.001). There was also a significant mean percentage decrease in the articulo-trochanteric distance index between 6 weeks and 3 months (p < 0.001). CONCLUSIONS: Primary stabilization with Knowles pins for impacted femoral neck fractures had a reasonable clinical outcome with low morbidity. Despite a significant difference of a mean percentage decrease in the articulo-trochanteric distance index between the successful group and the failure group, we could not verify it as a risk factor for failure of treatment because the odds ratio was not statistically significant.
