Milling system and methods for resecting a joint articulation surface
First Claim
1. A milling system for use in resecting at least a portion of a joint articulation surface of a bone, the system comprising:
- a template comprising;
a base having a top surface and an opposing bottom surface both extending from a first end to a spaced apart second end, the base including an opening extending between the top and bottom surfaces, at least two support legs projecting from the base so as to project below the bottom surface, the at least two support legs being interposed between the bottom surface of the base and a bone when the template is mounted to the bone;
a bracket upwardly projecting from the base, the bracket having an elongated guide slot extending from the first end to the second end of the base;
means for removably mounting the template on the bone when the at least two support legs are resting on the bone so as to suspend the bottom surface of the base of the template above the bone;
an elongated guide mounted to the bracket and projecting across at least a portion of the opening of the template, the guide being mounted to the bracket so that the guide can be selectively moved along the guide slot and can be rigidly fixed to the bracket at different locations along the guide slot, anda rotatable mill movably engaged with the guide so as to be selectively movable within the opening of the template.

Abstract
A milling system for use in resecting at least a portion of a joint articulation surface of a bone includes a template having a base with a top surface, an opposing bottom surface, and an opening extending therebetween. One or more fasteners are used to removably mount the template on a bone. A guide is movably mounted on the template and projecting across at least a portion of the opening of the template. The guide is selectively movable across at least a portion of the opening of the template. A rotatable mill is mounted on the guide. The mill is selectively movable along at least a portion of the length of the guide.

12. A milling system for use in resecting at least a portion of a joint articulation surface of a bone, the system comprising:
-
a template comprising a base having a top surface and an opposing bottom surface both extending from a first end to a spaced apart second end and from a first side to a spaced apart second side, the base including an opening extending between the top and bottom surfaces; means for removably mounting the template on a bone; a guide extending between a first end and a spaced apart second end, the guide being mounted on the template and projecting between the first and second sides of the template across the opening of the template, the entire guide being movable between the first end of the template and the second end of the template while the guide is coupled to the template; and a rotatable mill mounted on the guide, the mill being selectively movable at least substantially between the first and second sides of the template while mounted on the guide. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A milling system for use in resecting at least a portion of a joint articulation surface of a bone, the system comprising:
-
a template comprising a base having a top surface and an opposing bottom surface with an opening extending therebetween, the base also having a first end and an opposing second end with the opening positioned therebetween; means for removably mounting the template on a bone; a guide mounted to the template and projecting across the opening of the template, the entire guide being movable from the first end of the base to the second end of the base while the guide is mounted to the template; a brace movably mounted on the template so as to extend over a portion of the opening of the template, the brace being spaced apart from the guide; and a rotatable mill supported by the brace and the guide, at least a portion of the mill being disposed within the opening of the template. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A system for use in resecting at least a portion of a joint articulation surface of a bone, the system comprising:
-
a mill comprising an elongated shaft having a burr mounted on an end thereof; a tubular sleeve having a passage extending therethrough, the mill being rotatably disposed within the tubular sleeve; a retainer having a passage extending therethrough, the tubular sleeve being at least partially disposed within the passage, the retainer being releasably lockable to the tubular sleeve at at least two spaced apart locations along the length of the tubular sleeve, the retainer being moved along the length of the tubular sleeve when the retainer is moved to lock with the tubular sleeve at each of the at least two spaced apart locations; and an elongated guide, the retainer being movably coupled with the guide so as to be movable in a direction substantially normal to the elongated shaft of the mill, the guide allowing the mill to move in three dimensions so as to form a substantially continuous non-planar resected surface on a bone. - View Dependent Claims (33, 34, 35, 36, 37)
