Bufferable Femoral Implant

摘要

A bufferable femoral implant includes a metallic main body, and an elastomer member integrally formed or connected to a lower portion of the metallic main body, whereby when an external force acts upon the femoral implant as implanted in a patient's femur, the elastomer member as packed within the medullary cavity in the femur will bufferably dampen such an external force for safely protecting the patient's femur, the femoral implant and the related hip bones.

1. A bufferable femoral implant comprising:
a femoral stem adapted to be implanted into a medullary cavity of a patient's femur; said femoral stem including: a metal main body adapted to be inserted into said medullary cavity of said femur, said metal main body including a plug member, which is connected with a coupling rod as longitudinally protruded downwardly; and an elastomer member integrally formed or connected with said coupling rod of said main body, and adapted to be inserted into said medullary cavity below said main body; whereby upon impacting by an external force on said femoral stem, said elastomer member will dampen or buffer a stress caused by the external force for protecting said femoral implant and the patient's femur.
