Abstract
An arthrodesis surgical method and apparatus. After a guide pin is inserted into the joint to be fused, a core saw creates a cored-out cavity in the joint to be fixated. An autograft bone core is harvested with a core saw and is inserted into the cored-out cavity. The joint is then immobilized for the healing process.
Claims8
Apparatus to facilitate fusion of bone joints, the apparatus comprising:
- an elongated, cannulated core saw device having saw teeth at one end, said core saw device being open ended and hollow throughout its length, the opposite end of said core saw device being engageable by a drill bit of a power drill;
- an elongated, cannulated plunger which has a stem configured to extend through and is longer than said hollow core saw device, said plunger being sized to fit within the end of said core saw device within said saw teeth;
- and
- an elongated guide pin which is configured to extend through and is longer than said plunger;
- said guide pin, said plunger, and said core saw device being coaxial;
- after said guide pin is inserted into a joint to be fused, said plunger is inserted over said guide pin and said core saw device is inserted over said plunger and said core saw device is rotated to core out adjacent bones and cartilage to form a core opening configured to receive an autograft core.

A method for facilitating bone joint fusion, comprising:
- inserting a K-wire diagonally through a joint to be fused to stabilize the joint;
- inserting an elongated guide pin in a joint at the location of the fusing;
- inserting an elongated, cannulated plunger over the guide pin;
- inserting an elongated core saw device over the plunger, a core saw device having a first core saw head of a first diameter and a second core saw head of a second, larger diameter;
- rotating the first core saw head of the core saw device to remove bone and cartilage material to form a cylindrical hole in the joint to be fused;
- removing thus cored out material;
- removing the core saw device, guide pin, and plunger from the joint to be fused;
- harvesting an autograft bone core from the patient;
- and
- inserting the autograft bone core into the cored out hole created by removing the bone and cartilage material.
