Abstract

A guide for a bone cut comprises a guide base having an inner wall defining an opening. The inner wall has a plurality of detents distributed around the opening. The guide base has a proximal surface adapted to contact a skin of a person. An inner collar has one or more spring loaded devices extending outward from the inner collar in opposite directions. The inner collar is mountable with the spring loaded devices fitting within one or more of the plurality of detents. The inner collar has an inner wall defining a bore for receiving a cutting tool. The inner collar is configured to pivot the cutting tool about an axis, for cutting a bone. The axis lies along or parallel to a line along which the spring loaded devices lie.

First claim

What is claimed is:

1. A guide for cutting a bone, comprising:
a cylindrical body having:
a proximal surface adapted to contact a skin of a person, the proximal surface having a proximal chamfer at a center thereof,
a distal surface opposite the proximal surface, the distal surface having a distal chamfer at a center thereof,
the cylindrical body having an inner wall defining a central longitudinal bore extending through the body from the proximal chamfer to the distal chamfer, the central bore adapted to receive a drilling or cutting tool therethrough, and
the cylindrical body having a circumferential surface with a plurality of radial bores extending inward from the circumferential edge, the radial bores adapted to receive fixation elements therein.

2. The guide of claim 1 , wherein each of the plurality of radial bores is adapted to receive a k-wire.

3. The guide of claim 1 , wherein the body comprises a radiolucent material.

4. The guide of claim 1 , wherein the body comprises a pressure-sensitive adhesive on a peripheral portion of the proximal surface.

5. The guide of claim 4 , wherein the pressure-sensitive adhesive is applied in an annular ring adjacent to a circumference of a peripheral surface of the body.

6. The guide of claim 5 , wherein the pressure-sensitive adhesive is applied in a plurality of discrete areas of the body.

7. The guide of claim 1 , comprising ten radial bores evenly spaced 36° apart.

8. The guide of claim 1 , comprising a plurality of radial bores evenly spaced 36° apart and a plurality of adjacent radial bores evenly spaced 18° apart.
