ABSTRACT:
An osteotomy procedure for adjusting the conformation of a long-bone is described. Illustratively, a proximal tibial osteotomy procedure produces two relatively rotatable long-bone segments. A jig including a body and having two pins extending therefrom in the same direction in a plane containing the long axis of the jig preferably is used to adjustably fix the two segments relative to one another with each pin securely fixed within a corresponding one of the segments. Importantly, at least the distal pin is bendable such that a desired rotation with two degrees of freedom is achievable between the two to-be-fixed segments. By bending the distal pin in a region thereof extending between the jig body and the distal segment, any desired relative rotation may be achieved between the segments. Correction of any and all conditions including varus, valgus, internal and external rotation may be accomplished in a single osteotomy procedure.
