Functional evaluation in distal femoral endoprosthetic replacement for bone sarcoma.

A multicenter study of successfully treated patients (mean age, 36.7 years) with a minimum 1-year followup (average, 35.4 months) after distal femoral endoprosthetic replacement for bone sarcoma was done using the 1987 and 1993 versions of the Musculoskeletal Tumor Society, the Short Form-36, and the Toronto Extremity Salvage Score functional evaluation criteria. Fifty-six patients (28 women and 28 men) fulfilled the criteria. Thirty-one Kotz prostheses (fixed hinge, uncemented) and 25 Modular Replacement System Prostheses (rotating hinge, cemented) were used. Thirty-five patients walked without aids, 19 used a cane, and two used crutches or a walker. The Musculoskeletal Tumor Society 1987 mean score was 28.1. The Musculoskeletal Tumor Society 1993 mean score was 80.4. The Toronto Extremity Salvage Score mean was 81.6. The Short Form-36 Physical Component Score had a mean of 43.2 and Mental Component Score mean of 54.2. The two groups of implants were comparable, except for the length of bone resection. Multivariate regression analysis revealed that patient age, existence of a pathologic fracture, and type of prosthesis all significantly accounted for differences in functional outcome as measured by the Musculoskeletal Tumor Society 1993, the Toronto Extremity Salvage Score, and the Short Form-36 Physical Component Score scales. Although both implants provided satisfactory function, the Musculoskeletal Tumor Society 1993 and the Toronto Extremity Salvage Score results were significantly better with the Modular Replacement System prosthesis. The effect of possible differences among surgeons or institutions was not addressed.

Chondroblastoma.

Chondroblastoma of the bone is a benign tumor that has well-characterized radiographic and histologic features. It tends to affect the epiphyseal ends of long bones in men during the second and third decades of life. The tumor is located more frequently at other sites in older patients. The treatment of choice is complete curettage with bone grafting, which in our series provided local control in 82% of patients at 2 years' follow-up. Recurrent tumors usually can be treated in the same manner.

Unstable intertrochanteric fracture of the femur. A prospective randomised study comparing anatomical reduction and medial displacement osteotomy.

We conducted a prospective randomised trial to compare the results of anatomical reduction and medial displacement osteotomy in 127 consecutive patients with unstable intertrochanteric fractures, of whom 109 completed the study. After an average follow-up of 11 months, we found no significant differences in walking ability, social status or failure of fixation in the two groups. Postoperative complication rates and the early mortality rate were not significantly different, but operating time and blood loss were significantly higher in the osteotomy group. With the use of modern sliding hip screws, medial displacement osteotomy is rarely indicated for unstable intertrochanteric fractures.

Malignant fibrous histiocytoma of the soft tissues of the trunk and extremities.

Malignant fibrous histiocytoma (MFH) is the most commonly diagnosed soft-tissue sarcoma. Of 408 retrospectively reviewed patients with MFH, 220 patients had primary, localized, previously untreated tumors involving the extremities or limb girdles. Univariate statistical analysis of results revealed five prognostic factors that were significantly related to poor outcome: old age, deeply seated lesions, surgical grade, large size, and marginal or intralesional surgery. Multivariate analysis revealed only three factors that were significantly related to poor prognosis: old age, deeply seated lesions, and inadequate surgery.

Giant cell tumor of the sacrum.

Twenty-six patients (18 women and eight men) with giant cell tumors of the sacrum were treated from 1960 through 1986. The mean age of the patients was 29 years. The follow-up duration averaged 7.8 years. A neurologic deficit was present in 88%. Sixteen patients had not had a previous operation. Ten patients were referred for local recurrence. Twenty-one patients had radiation therapy; malignant transformation later occurred in three. Three benign giant cell tumors metastasized to the lungs. The local recurrence rate for patients treated by curettage was 33%. Three patients died of tumor-related complications. At the completion of this study, two patients were alive with disease. The suggested initial treatment is complete curettage. Radiation therapy should be reserved for incomplete resection and local recurrence. Occasionally, patients may require wide resection, which may cause a severe neurologic deficit and compromise spinal stability.
