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.

We evaluated 108 endoscopically assisted carpal tunnel releases in 90 patients in a retrospective study to determine the efficiency and safety of a modified Okutsu endoscopic carpal tunnel release (ECTR) technique. The modification consisted of the use of glass tubes 5, 7, and 9 mm in diameter and a sharp tipped hook knife. The results were evaluated using a patient questionnaire, time off from work, grip strength, and two point discrimination. Symptoms were resolved in 71% of the patients, improved in 19.4%, and not improved in 9.3%. In this series, 59 patients were gainfully employed: 84.7% returned to work, half within 2 weeks of surgery. Severe complications included one laceration of the ulnar nerve, and one neuroma in continuity of the median nerve. ECTR using this modification of Okutsu's technique is effective in the relief of symptoms and returning patients to work quickly.

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.
