Long term results of fixed-hinge megaprostheses in limb salvage for malignancy.

We retrospectively studied the files of 669 patients with musculoskeletal tumors treated with limb salvage and reconstruction using fixed-hinge knee megaprostheses. We used the KMFTR® prosthesis from 1983 to 1989 in 126 patients, and the HMRS® prosthesis thereafter in 543 patients because of the anatomical femoral stem with one lateral flange for improved stress-shielding, the new hinge design and new generation polyethylene placed centrally in the metallic hinge, and the improved function compared to the former prosthesis. Distal femoral reconstructions were done in 474, proximal tibia in 163, extrarticular knee joint in nine, and total femoral in 23 patients.

Malignant bone tumors in Kuwait: a 10-year clinicopathological study.

Between 1995 and 2004, 142 malignant bone tumours comprising 76 primary and 66 secondary tumours were identified in the Pathology Department of Al-Sabah Hospital, Kuwait. Pathological fracture was the presenting sign in 35% of the cases. The mean incidence of primary tumours/year was 3.

Growth arrest resulting from unicameral bone cyst.

Growth arrest complicating unicameral bone cyst of the proximal humerus is reported in five patients. These patients represented 10% of 51 consecutive patients treated by the senior author at our hospital from 1988 through 1995. The youngest patient at first clinical presentation was aged 6 years, and the oldest was 14 years 9 months.
