Preservation of lower extremity function followed by pelvic tumor resection

In 192 operated patients with tumors and tumorlike diseases functional results were analyzed. In 162 patients radical sparing operations were performed according to oncologic demands and with preservation of static-dynamic function of pelvic girdle and lower extremity. High efficacy of those operations was confirmed by clinical and biomechanical data. Long term results showed the necessity to perfect reconstructive surgery on pelvic posterior semi-ring. Elaborated variants of plastic operations for the substitution of acetabular zone allow to restore the hip joint function after resection of pubic, iliac and ischium bones. When the anterior pelvic ring is disturbed bone defects should not be repaired as static-dynamic function is preserved due to compensatory mechanism of sacroiliac ligaments.
