Porous spacers, instruments, and methods for foot and ankle fusion

摘要

A method for implanting porous spacers (100) for foot and ankle fusion between separate bones of a joint or between two segments of a single bone following an osteotomy procedure. Such spacers may be used in conjunction with an ankle resection system which includes a resection frame (150 and a resection guide (1780). The resection frame can be anchored to the distal tibia and/or the talus and provides an opening (155) through which a bone cutting element can pass for cutting underlying bone. The resection guide can include one or more cutting slots (160,171,172) and the resection guide can be coupled to the resection frame with the one or more cutting slots positioned over the opening in the resection frame so that the bone cutting element can pass through the one or more cutting slots and through the opening in the resection frame for cutting the distal tibia and/or the talus.

主权项

1. A method for resecting bone, comprising:
positioning a resection frame over bone, the resection frame including an opening through which a bone cutting element can pass for cutting underlying bone; locking a resection guide including one or more cutting slots to the resection frame to position the one or more cutting slots in a first position over the opening in the resection frame, such that the bone cutting element can pass through the one or more cutting slots; and passing a bone cutting element through the one or more cutting slots in the resection guide and through the opening in the resection frame to make one or more resection cuts in underlying bone that each extend in an elongate fashion along an exterior surface of the underlying bone; wherein the resection guide and resection frame are unlockable from one another to permit translation of one of the resection guide and the resection frame from the other of the resection guide and the resection frame in a longitudinal direction for repositioning the one or more cutting slots from the first position to a second position over the opening in the resection frame; wherein the resection guide is relockable to the resection frame to fix the one or more cutting slots in the second position over the opening in the resection frame.
