Methylmethacrylate As an Adjunct in Internal Fixation of Pathological Fractures. Experience with Three Hundred and Seventy-five Cases

In 323 patients with 375 pathological fractures or impending fractures, local tumor resection and internal fixation supplemented by intramedullary methylmethacrylate proved highly successful. One hundred and thirty-nine patients had metastases from breast carcinoma; 142, metastases from other tumors; and forty-two, myeloma or lymphoma. The mean survival for the 210 patients who had undergone operation two years or more before final evaluation was 15.4 months. Ninety-four per cent of the patients who were ambulatory before fracture regained the ability to walk. Eighty-five per cent had excellent or good pain relief and in only five was pain relief rated poor. There were four failures of fixation and six functionally poor results. Twenty patients died within four weeks of operation, but the remaining patients benefited from the procedure in terms of pain relief, improved mobility, and ease of nursing care.
