Titanium-Polyethylene Implant to Prevent Terminal Osseous Overgrowth

ERNST MARQUARDT, MD*


Stump-capping using an autogenous cartilage-covered cap has been successful since 1974, except for a few well analyzed cases. Some children are unsuited for the procedure, where it is impossible to take an autogenous transplant from the amputated part. In such cases, we use MECRON-Endo-Stump Cap consisting of a titanium plate, screws for fixation to the bone, and a polyethylene outer cap with a catch spring inside for its fixation to the plate, and with drill holes outside for fixation of muscles to the cap. Indications, contraindications, surgical technique, and first results are described.
