Ulnar Nerve Transposition (Cadaver)
Irene Kalbian; Asif M. Ilyas, MD, MBA, FACS
Ulnar nerve transposition is a surgical procedure performed to treat ulnar nerve compression of the elbow, also known as cubital tunnel syndrome. This procedure is utilized after both non-operative management and in situ decompression fails, or if these procedures are deemed inappropriate based on patient pathology or ulnar nerve instability.
Transposition of the ulnar nerve involves not only decompression of the nerve but also its anterior repositioning to reduce compression and irritation while maintaining nerve integrity. This video demonstrates, on a cadaver arm, the operative technique for performing an ulnar nerve transposition using either a subcutaneous or a submuscular technique.

Sagittal band rupture leads to subluxation of the EDC tendon at the MCP joint. The common presentation involves pain and swelling at the MCP joint, visualization of extensor tendon subluxation during flexion, and inability to actively extend the MCP joint from a flexed position.
The treatment for chronic rupture, as in this case, involves surgical repair followed by six weeks in a relative motion splint, in which the injured MCP joint is placed in greater extension relative to adjacent joints. The video here demonstrates direct repair of a chronic degenerative sagittal band rupture of the right ring finger.
