Revision Carpal Tunnel Release in a Case of Proximal Median Nerve Hematoma Injury and Mild Compression
Extended Version (7.120301.120229)

Complications following carpal tunnel release are uncommon with patients experiencing persistent, recurrent, or new symptoms in the post-operative period. There are multiple etiologies for recurrent carpal tunnel syndrome, which can include traction neuropathy. This is when the epineurium of the median nerve adheres to the surrounding scar tissue and prevents normal nerve gliding leading to traction neuritis. This patient lost median nerve function due to a hematoma compression that developed from a peripherally inserted central catheter in the arm. While this patient did not have sensory function, he was recovering pronator teres and flexor carpi radialis function. For any possibility of sensory recovery, a revision carpal tunnel release was performed to ensure a complete release and mild compression of the median nerve was observed. The median motor function was augmented with a reverse end-to-side nerve transfer. This case is also a demonstration of bifid median nerve in the hand.
