Bone graft and preliminary fixation
Once the articular surface has been reconstructed, the distraction can be adjusted. It is helpful to have comparative x-rays from the uninjured side. This allows one to judge the proper length and morphology.
Any remaining defects, if necessary, are filled with either a bone graft or a substitute.
While reconstructing the joint surface, check frequently to make sure no malreduction ensues.
While the opposing surface serves well as a template, if one secures the assembled fragments to it with K-wires, the verification of joint congruency becomes very difficult.
