Open Carpal Tunnel Release

Ulnar nerve neuropathy is a rare complication following the carpal tunnel release. Above all, compression neuropathy is much rare. We report an acute ulnar nerve neuropathy following open carpal tunnel release due to the volar and ulnar displacement of the flexor tendons from the carpal tunnel and review the literature.

Tunnel Syndrome

Compression neuropathy of the ulnar nerve at the elbow is well-recognised as cubital tunnel syndrome (CuTS). Many causes of ulnar neuropathy at the elbow have been identified. A previously unreported finding of ulnar nerve compression in the cubital tunnel caused by a thrombosed proximal ulnar recurrent artery vena comitans is described.

Introduction: Aberrant positioning of the ulnar nerve volar to the transverse carpal ligament is a rare anatomic variation.Case Presentation: We present the case of a 55-year-old female with unique ulnar nerve anatomy that was discovered introperatively during carpal tunnel release.  The ulnar nerve was running directly adjacent to the median nerve in the distal forearm and as the median nerve traversed dorsal to the transverse carpal ligament (flexor retinaculum) to enter the carpal tunnel the ulnar nerve continued directly volar to this structure before angling towards Guyon’s Canal.  The unique ulnar nerve anatomy was successfully identified, carefully dissected and managed with a successful patient outcome.Conclusion: Variations of the anatomy at the level of the carpal tunnel are rare but do exist.  Awareness of these anatomic variations and adequate visualization of the ulnar nerve along with the surrounding structures is crucial to avoid iatrogenic injuries during carpal tunnel release.

Open Carpal Tunnel Release

We present a case of carpal tunnel syndrome involving wrist trigger caused by a hypertrophied lumbrical muscle with flexor synovitis. The case was a 40-year-old male heavy manual worker complaining of numbness and pain in the median nerve area. On active flexion of the fingers, snapping was observed at the carpal area, and forceful full grip was impossible. Tinel’s sign was positive and an electromyographic study revealed conduction disturbance of the median nerve at the carpal tunnel. Magnetic resonance imaging revealed edematous lumbrical muscle with synovial proliferation around the flexor tendons. Open carpal tunnel release was performed under local anesthesia. Synovial proliferation of the flexor tendons was found and when flexing the index and middle fingers, the lumbrical muscle was drawn into the carpal tunnel with a triggering phenomenon. After releasing the carpal tunnel, the triggering phenomenon and painful numbness improved.

Open Carpal Tunnel Release

ABSTRACTopen carpal tunnel release is the commonest surgical treatment of median nerve compression at the wrist. although successful in most cases, there are well described complications. we report a case of laceration of the deep motor branch of the ulnar nerve at the level of the hook of hamate following a complicated carpal tunnel decompression. good surgical technique and knowledge of wrist anatomy are essential for performing this apparently simple procedure safely.
