Abstract:
The irregular anatomic morphology of proximal femoral medullary cavity does not match the current regular prosthetic stem,which is a primary cause of prosthesis loosening post-surgery. The newly designed artificial furcal interior locking joint features irregular prosthetic stem, which adapts to the irregular medullary cavity in the proximal femur. The artificial furcal interior locking joint is anchored in a multi-plane and multi-point manner. Together it can prevent prothetic early peristalsis and late loosening in the medullary cavity post-surgery. Therefore, artificial furcal interior locking joint is promising for prosthetic replacement.
