title: A modular endoprosthetic system for tumor and non-tumor reconstruction: preliminary experience.
abstract: Though originally designed to facilitate the management of primary malignant bone tumors, the indications for the Howmedica Oncology modular endoprostheses have expanded to include the reconstruction of metastatic lesions, failed internal fixation of difficult trauma problems, and failed conventional and custom tumor endoprostheses. Between July 1989 and August 1992, 24 patients underwent 25 procedures, either proximal humeral replacement (7), proximal femoral replacement (5), distal femoral replacement (9), or total femoral replacement (4). Diagnoses included primary bone tumor (6), metastases (5), and failed previous orthopedic intervention (14). Two early and four late complications in five patients were all treated successfully with surgical or nonoperative treatment. Preliminary functional results indicate very satisfactory results. Modular endoprostheses appear to be effective in the treatment of a wide range of diagnoses, not limited to the reconstruction following primary malignant bone tumor resections.
