Abstract
The invention herein described is an endoprosthesis intended to replace a resected portion of bone and joint. The invention can be non-invasively, manually operated to lengthen a patient's limb both intraoperatively and postoperatively. It includes bone anchoring components for anchoring to a first and second long bone, a joint to replace the function of an orthopedic joint, and a purely mechanical lengthening mechanism which can be located and operated manually by an operator by pressing on skin of a patient without requiring a surgical incision. An alternative embodiment of the invention describes a similar extendable endoprosthesis which is unlocked by an operator by pressing on skin of a patient and the limb is subsequently pulled or pushed by the operator to change its length. The invention does not need or include any magnets, electric motors, electric current, application of heat or a fluid displacement (hydraulic) system.
