Adjustable cut guide
First Claim
1. An adjustable cut guide for use in resecting the end of a bone, the bone having an anterior side and a posterior side, the cut guide comprising:
- a base adapted to attach to the end of the bone, said base including an anterior end and an opposite posterior end;
first and second guide housings coupled to said base and disposed adjacent said opposing anterior and posterior ends, respectively, of said base;
anterior and posterior guide members rotatably coupled to said first and second guide housings, respectively, each of said anterior and posterior guide members rotatable about a guide axis and having an elongate guide slot extending along said guide axis and extending through said guide member in a direction transverse to said guide axis, whereby a cutting device guided through said elongate guide slot extends transverse to said guide axis, said anterior and said posterior guide members being rotatable about said guide axis to a first position in which said elongate guide slots are positioned in a first orientation and a second position in which said elongate guide slots are positioned in a second orientation, said first orientation of said elongate guide slots angled relative to said second orientation of said elongate guide slots, said first orientation of said elongate guide slots and said second orientation of said elongate guide slots being non-coincident;
wherein when said base is attached to the end of the bone said anterior guide member is positioned proximal the anterior side of the bone and said posterior guide member is positioned proximal the posterior side of the bone.

Abstract
An adjustable cut guide for use in resecting the end of a bone. The cut guide of the includes guide slots, the position of which may be adjusted to one of multiple guiding positions that guide a saw in making the anterior, posterior and/or chamfer cuts in the bone. The cut guide includes a base adapted to attach to the end of a bone and including an anterior end and a posterior end. First and second guide housings are coupled to the base and disposed adjacent the opposing anterior and posterior ends, respectively. Anterior and posterior guide members are rotatably coupled to the first and second guide housings, respectively. Each of the anterior and posterior guide members are rotatable about a guide axis and have a guide slot extending therethrough along the guide axis.
