| 摘要 |
A prosthetic joint for the replacement of the ankle joint comprising a tibial member and a talar member each having three distinct complementary bearing surfaces which allow plantar and dorsal flexion and some rotation approximating the movement of the natural ankle joint. The talar member has three adjacent bearing surfaces which are each longitudinally and laterally convexly shaped and the tibial member is provided with three substantially complementary longitudinally and laterally concavely shaped bearing surfaces that provide medial-lateral support while allowing about 5 DEG rotation between the members.
