APPARATUS AND METHOD FOR REPLACEMENT OF A METATARSOPHALANGEAL JOINT WITH INTERPHALANGEAL FUSION

摘要

An apparatus and method for partial replacement of a metatarsophalangeal joint defined by a proximal face of a phalanx and a distal face of a metatarsal. The apparatus and method include a joint surface element and an elongated fusing element. The elongated fusing element has an end configured for tool engagement. The joint surface element has a generally concave surface configured to serve as the proximal face of the phalanx and a socket configured to engage the end of the elongated fusing element. The elongated fusing element fuses an interphalangeal joint when the apparatus is surgically implanted to prevent the deterioration of the interphalangeal joint.
