Curved Arthroscopic Burr and Measurement Instrumentation

A talar bone burr, the burr comprising:

• a drive shaft;
• a housing extending between proximal and distal ends, a portion of the housing extending along a curved path forming a curved casing portion, the housing comprising a housing window;
• a plurality of bushings fitted into the housing;
• and
• a plurality of cutting inserts coupled together in a sequence extending along the curved path and partially received in the housing window, a proximal-most cutting insert coupled to the drive shaft, wherein each cutting insert comprises at least one cutting edge and wherein each cutting insert is differently shaped than each of the other cutting inserts.

A method for resecting a talar bone to receive an implant, the method comprising:

• inserting a portion of a talar bone resection device into the patient's body;
• engaging the talar bone with the talar bone resection device, the talar bone resection device comprising a drive shaft, a housing extending between proximal and distal ends, and a cutting assembly, a portion of the housing extending along an arcuate path forming an arcuate housing portion, the housing comprising a housing window,
• wherein the cutting assembly further comprises a plurality of cutting inserts coupled together in a sequence extending along the arcuate path and partially received in the housing window, wherein the plurality of cutting inserts comprises a cutting profile wherein the cutting profile comprises a first straight portion, a curved portion and a second straight portion;
• powering the talar bone resection device;
• and
• moving the cutting assembly of the device in a medial-lateral direction over the bone surface.
