【摘要】 股骨近端髓腔不规则的解剖形态与目前规则的假体杆柄不完全匹配,是引起术后假体松动的主要原因之一。新设计的分叉内锁式人工关节把现有假体规则性杆柄变为不规则,适应了股骨近端不规则性髓腔。并呈多平面、多点位锚固,多方向防止术后假体在髓腔内的早期蠕动和晚期的松动,给人工关节置换带来一个新的方法和新的希望。更多还原

【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.更多还原
