Summary
Revision anterior subcutaneous transposition effectively treated recurrent ulnar nerve compression. Patients experienced significant improvements in symptoms, grip strength, and nerve conduction after this revision surgery.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Nerve Compression Syndromes
Background:
- Recurrent ulnar nerve compression post-anterior subcutaneous transposition is uncommon.
- Revision surgery for this condition presents unique challenges.
Purpose of the Study:
- To evaluate the clinical outcomes of revision anterior subcutaneous transposition for recurrent ulnar nerve compression.
Main Methods:
- Retrospective study of eight patients undergoing revision surgery.
- Assessment of preoperative and postoperative symptoms, physical examination, and electromyography.
Main Results:
- Significant improvements in numbness, grip strength (48% to 80%), and McGowan grade (III to I).
- Enhanced motor and sensory nerve conduction velocities and amplitudes post-revision.
- Ulnar nerve enlargement noted preoperatively in all patients.
Conclusions:
- Revision anterior subcutaneous transposition is an effective treatment for recurrent ulnar nerve compression.
- The procedure successfully addressed compression from prior failed surgeries.
