Upper extremity fusion devices and methods
First Claim
1. A surgical instrument for use in obtaining bone fusion in an upper extremity of a patient, the instrument comprising:
- a fusion implant including a first end, a second end and a body extending longitudinally therebetween defining a first axis, the body including at least one aperture extending laterally therein defining a second axis;
a targeting member including at least one arm, at least one bone fusion member aperture configured to receive a bone anchor therethrough, and at least one clamp member configured to securely couple with a bone anchor member clamp, the at least one clamp member defining a first side surface, a second slotted side surface and an aperture extending through the clamp member from the first side surface to the second slotted side surface, said second slotted side surface including at least one slot which includes a section that is spaced apart from said aperture of said at least one clamp member;
at least one guide member coupled to the at least one arm of the targeting member and including an aperture extending through the at least one guide member defining a third axis; and
an outrigger member coupled to the at least one arm of the targeting member and securely removably coupled to the first end of the fusion implant in a first orientation of the fusion implant,wherein the outrigger member and the at least one guide member are configured such that the second axis of the bone fusion member aperture of the fusion implant and the third axis of the aperture of the at least one guide member are substantially aligned in the first orientation of the fusion implant.

Abstract
A fusion implant and fusion members for fusing target bones of an upper extremity. The fusion implant including internally threaded apertures of a first thread lead, and the fusion members including threading of the first thread lead and threading of a second thread lead that is less than the first thread lead. The fusion implant and a targeting instrument being configured to couple to one another in a predefined orientation. The predetermined orientation resulting in alignment of aspects of the fusion implant with aspects of the targeting instrument. A guide clamp for facilitating forming of an implant cavity in adjacent bones for implantation of the fusion implant therein. A surgical method for facilitating fusion of adjacent target bones utilizing a fusion implant, fusion members, a targeting instrument and a guide clamp to reduce space between the adjacent bones such that they at least abut one another.
