First claim

What is claimed is:

1. A method of attaching a jig to a bone during a surgery, the method comprising the steps of:

providing a cutting jig with a bore;
driving the surgical orthopedic pin into the bone from a first, inoperative position outside the bone, at which the restraining device is disposed within a bore of the jig, and compressing the restraining device in a radial direction at the first position, to a second, operative position in the bone spaced from the first position, in which the pin holds the jig to the bone; and
retracting the surgical orthopedic pin out of the bone from the second, operative position in the bone so as to loosen the jig.

2. The method of claim 1 , including the step of releasably securing the pin within the bore defined by the jig using the restraining device associated with the pin at a location removed from the bone.

3. The method of claim 1 , including the step of releasably locking the pin in the bore.

4. The method of claim 1 , including the step of using the pin in conjunction with a surgical navigation system.

5. The method of claim 1 , wherein the step of providing the pin includes providing the restraining device as an adhesive carried by the pin.

6. The method of claim 1 , wherein the step of providing the pin includes providing the resilient member as a tension ring.

7. The method of claim 1 , wherein the step of providing the pin includes providing the restraining device as a ball plunger.
