Upper Extremity Tendinopathies (trigger digits, deQuervains, Lateral epicondylitis)-Hand Surgery Update IV: First Dorsal Extensor Compartment Release

Hand Surgery Update IV: First Dorsal Extensor Compartment Release

Video Transcription

Video Summary

In this video, the surgeon demonstrates a technique to release the tendons in the first dorsal extensor compartment of the hand to treat stenosing tenosynovitis, commonly known as trigger thumb. The surgeon makes a longitudinal incision just below the radial styloid, ensuring to avoid the superficial radial nerve. The tendons are identified and protected, and a release is performed using tenotomy scissors on the dorsal side of the sheath to prevent subluxation. Multiple slips of the abductor pollicis longus tendon may be present, so it is important to verify complete release. After verifying, the wound is closed, and a splint is used for postoperative care.
