Abstract
Introduction The close proximity of the cutaneous and major nerves around the elbow have caused orthopaedic surgeons to feel uncomfortable about the prospect of performing basic and advanced elbow arthroscopy. The aim of this study was to review the proximity of the nerves with arthroscopic vision in a cadaveric model and selected clinical cases.
Methods Open exploration of the major nerves in the elbow was performed in alcohol preserved cadaveric specimens. Arthroscopic assessment of the elbow joint was performed before and after the capsule adjacent to the nerve was excised. The arthroscopic assessment of the major nerves in these specimens provided an excellent way to visualise the nerves.
Results The radial nerve was found to be in contact with the anterior capsule of the joint and was at great risk with portal placement, lateral sided procedures including synovectomy, radial head excision, capsulotmy and capsulectomy. The medial nerve was protected by the brachialis muscle. The ulnar nerve was also at risk in the medial gutter.
Conclusions The close proximity of the major nerves to the elbow joint places them at risk, with elbow arthroscopy. The radial and ulnar nerves are particularly close and their exact position can be dissected free with arthroscopic techniques.
