Method and apparatus for coupling soft tissue to a bone
First Claim
1. A method for attaching a fixation device to a bone, the method comprising:
- bringing a bone cutting tool that extends along a longitudinal axis into engagement with an outer surface of the bone;
rotating the bone cutting tool about the longitudinal axis while driving the bone cutting tool from the outer surface of the bone to a predetermined depth in the bone to form a bore;
continuously rotating the bone cutting tool at the predetermined depth while maintaining the bone cutting tool in a substantially stationary position to establish an enlarged bone pocket at a distal end of the bore, the bone pocket defining a shoulder extending around a circumference between the bone pocket and the bore;
removing the bone cutting tool from the bone pocket and the bore;
inserting the fixation device into the bone pocket through the bore; and
positioning the fixation device against the shoulder of the bone pocket.

Abstract
A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The method includes bringing a bone cutting tool extending along a longitudinal axis into engagement with an outer surface of the bone. The bone cutting tool is rotated about the longitudinal axis while driving it from the outer surface of the bone to a predetermined depth in the bone to form a bore. The bone cutting tool is then continuously rotated at the predetermined depth to establish an enlarged bone pocket at a distal end of the bore. The bone pocket defines a shoulder extending around a circumference between the bone pocket and bore. The bone cutting tool is removed from the bone pocket and bore. The fixation device is then inserted into the bone pocket through the bore, where it is seated against the bone pocket shoulder.

8. A method for attaching a fixation device to a bone, the method comprising:
-
bringing a bone cutting tool having a helical flute into engagement with an outer surface of the bone; rotating the bone cutting tool about a longitudinal axis to form a first bore having a helical flute groove extending from the outer surface of the bone to a depth within the bone; continuously rotating the bone cutting tool at the depth to establish a second bore having a shoulder and a continuous sidewall, the shoulder extending around a circumference between the second bore and the first bore; aligning the bone cutting tool with the first bore; drawing the bone cutting tool out of the second and first bores; inserting the fixation device into the second bore through the first bore; and positioning the fixation device against the shoulder of the second bore. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for attaching a fixation device to a bone, the method comprising:
-
advancing a bone cutting tool through cortical bone about a longitudinal axis of the tool to a predetermined depth in cancellous bone to form a bore having a helical groove, the bone cutting tool including a body portion extending from a proximal end to a distal end along the longitudinal axis, a first member extending radially outwardly from the distal end of the body portion, the first member having a first diameter defined by at least one transverse cutting flute, and a second member extending radially outwardly from the body portion proximal the first member and having a second diameter greater than the first diameter; and continuously rotating the bone cutting tool at a substantially stationary position at the predetermined depth to establish an enlarged bone pocket having a cylindrical sidewall at a distal end of the bore, the bone pocket defining a shoulder extending around a circumference between the bone pocket and the bore. - View Dependent Claims (15, 16, 17, 18, 19, 20)
