Symptomatic quadrilateral space syndrome is uncommon, but it can result in considerable pain, weakness, and decreased athletic performance in afflicted patients. Surgical intervention is occasionally required to reduce symptoms and avoid functional decline when non-surgical treatments fail. Surgeons have traditionally used open techniques to accomplish axillary nerve neurolysis, and they appear to provide satisfactory outcomes. Recent technical advances have allowed arthroscopic axillary nerve decompression techniques to be devised that may provide some benefits over open techniques. We describe the technique and early results of all-arthroscopic transcapsular axillary nerve decompression.
