Extra-articular mini-open proximal phalanx osteotomy with retrograde intramedullary headless screw under WALANT - Surgical technical.

We report on the surgical technique for mini-open derotation osteotomy using retrograde osteosynthesis by headless compression screw under WALANT anesthesia (video attached). Preoperative CT showed the feasibility of this technique, with a 2.2 mm headless compression screw. The mechanical stability of the resulting constructs combined with intraoperative active motion testing under WALANT authorized immediate rehabilitation without immobilization, thus preventing stiffness. Joint range of motion recovered by day 4 and bone consolidation was achieved at 30 days.
