Upper Extremity Tendinopathies (trigger digits, deQuervains, Lateral epicondylitis)-Hand Surgery Update IV: Trigger Thumb

Video Transcription

Video Summary

In this video, the treatment of trigger thumb, also known as stenosing tenosynovitis of the flexor pollicis longus, is demonstrated. The procedure involves making a transverse incision at the base of the thumb MCP joint flexion crease while ensuring the protection of the radial digital nerve. The use of a ragnell retractor safeguards the nerves and the ulnar nerve vascular bundle. The A1 pulley is then released using a 15 blade and tenotomy scissors, up to the limits of the oblique pulley. By assessing the tension on the flexor pollicis longus, it is confirmed that the pulley has been completely released, resulting in the elimination of triggering. The surgery also helped the patient achieve full extension. No credits were granted.
