[Endoscopic release of the carpal tunnel using the Agee technique modified by Neumann].

OBJECTIVE

Decompression of the median nerve by complete endoscopic release of the transverse carpal ligament (TCL) and the distal antebrachial fascia. Minimization of surgical trauma results in decreased postoperative morbidity and earlier return to work and daily activities.

INDICATIONS

Symptomatic carpal tunnel syndrome.

CONTRAINDICATIONS

Revision surgery after open or endoscopic procedure, rheumatic diseases.

SURGICAL TECHNIQUE

Small transverse incision at the ulnar border of the palmaris longus tendon, and proximal to the distal wrist flexion crease. Exposure and incision of the antebrachial fascia, dilatation of the carpal tunnel and dissection of synovial tissue from the undersurface of the TCL. With the wrist in extension, the endoscopic blade assembly with integrated camera is inserted into the canal. Exposure of TCL and short incision in the middle portion. Gradually, dissection of the distal portion of the TCL then completion by retraction of the blade distally to proximally.

POSTOPERATIVE MANAGEMENT

Slightly compressive dressing, selfcare on day 1 after procedure.

RESULTS

More than 25 years of experience, more than 8000 treated patients, and 3 documented cases with intraoperative lesions of the median nerve requiring revision. High acceptance and patient satisfaction in AQS1 patient-reported surveillance.
