Agee technique. A, U-shaped flap elevated in palmar direction. Synovium elevator prepares wrist for optimal endoscopic view by separating synovium from deep side of ligament. B, Safe zone of blade elevation is triangle defined by ulnar half of distal edge of transverse carpal ligament (a) ulnar border of median nerve, (b) median nerve common digital branch to long/ring web space, and (c) superficial palmar arch. C, Longitudinal cross section through carpal tunnel depicts blade elevation in triangular safe zone. D, Initial release facilitates accurate viewing and division of ligament. E, Inspection of incised transverse carpal ligament in which left view depicts incomplete release as V-shaped defect, with superficial fibers of transverse carpal ligament remaining intact. Center view depicts complete release of ligament after reinsertion of blade assembly. Fat and transverse fibers of palmar fascia that remain palmar to divided ligament can be noted. View on right shows that rotating blade assembly approximately 20 degrees in either direction causes separated cut edges of ligament to fall into window. F, Tenotomy scissors used to release forearm fascia proximal to skin incision. SEE TECHNIQUE 77.3.
