Ulnar Nerve Microsurgical Repair/Transplantation

The surgery is performed under a microscope, with options including end-to-end suture, nerve grafting (autograft/allograft), or artificial conduit bridging if necessary. The usual practice is to fully expose the affected nerve, clean up scar tissue and neuroma, mark the proximal and distal ends, and perform epineurial/perineurial alignment sutures under acceptable tension. Defects are bridged with grafts, and intraoperative electrophysiological stimulation is used for evaluation as appropriate. Subsequently, the layers are closed and external fixation is used for protection. In the early postoperative period, the focus is on monitoring limb perfusion, sensation, and muscle strength changes, maintaining wound cleanliness and appropriate immobilization, followed by gradual functional training under rehabilitation guidance, with the goal of creating a stable environment for axonal regeneration.
