Abstract
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.
