The instrument further includes a first gear coupled to the first end of the shaft. The instrument further includes a second gear enmeshed with the first gear. The instrument further includes a reamer coupled to the second gear. Rotation of the shaft about the first axis causes rotation of the reamer about a second axis that is non-parallel with the first axis. The distractor includes a first arm defining a first passage and a second arm defining a second passage, each configured to receive a pin. The distractor further includes a retainer configured to engage the instrument to retain the instrument in position. The distance between the first passage and the second passage is adjustable.

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.

Abstract: A system and method for use when forming an osteotomy that rely upon an arrangement of surgical instruments with a targeting guide having a handle extending substantially along a longitudinal axis, with one or more burr holes extending from a first side of the handle to a second side of the handle. A head is coupled to a distal end of the longitudinal handle. The head defines a plurality of guide holes sized and configured to receive a k-wire therethrough. The arrangement allows accurate adjustment of the surgical instruments in relation to the bones targeted for the osteotomy.

Abstract: A system and method for performing a percutaneous bunionectomy. The system including a jig, which subsequent to attachment and performance of an osteotomy on the bone, uses a rack and pinion mechanism to translate the separated portion of the bone to a surgeon determined displacement ?. A locking mechanism maintains the desired displacement of the bone portions and allows the surgeon, with use of an attached visual guide, to insert a k-wire through the bone portions to serve as a guide wire for the internal fixation that maintains the displacement during the healing. The system removes the requirement that the surgeon manually maintain the desired displacement while inserting the guide wire.
