Endoscopic Ganglionectomy of the Volar Radial Wrist Ganglion

Arthroscopic Tenovaginotomy and Ganglion Excision of the Flexor Carpi Radialis Fibro-Osseous Tendon Sheath

The treatment of flexor carpi radialis (FCR) tendon stenosing tenosynovitis recalcitrant to nonsurgical intervention has been open or blind tenovaginotomy of the volar trapezial fibro-osseous sheath of the FCR tendon. The surgical literature has not reported arthroscopic tenovaginotomy of the FCR fibro-osseous tendon sheath with or without associated ganglia. This report describes a technique of arthroscopic tenovaginotomy for stenosing tenosynovitis of the FCR tendon at the trapezial fibro-osseous sheath with or without excision of any associated ganglion through a not previously described new volar radial trapezial arthroscopic portal.

Endoscopically Assisted Myectomy for Intramuscular Lipoma of Pronator Quadratus

Intramuscular lipoma is usually growing infiltratively and can affect any muscle, although the proximal muscles of the extremities are mostly commonly involved. This lesion can occur in the pronator quadratus. Because of muscle is small and deep seated, the intramuscular lipoma usually involves the whole muscle and even has an extramuscular component before it presents clinically. In this Technical Note, we report the technique of endoscopically assisted myectomy of the pronator quadratus for infiltrating intramuscular lipoma of the muscle. This has the advantage of minimally invasive surgery of minimal soft tissue dissection and fewer soft tissue complications.

Endoscopic Release of the Guyon Canal and Pisohamate Hiatus

The ulnar nerve runs in more than 1 tunnel in the wrist. Ulnar nerve entrapment in the wrist can occur at the Guyon canal and the pisohamate hiatus. Open release of these 2 tunnels requires a lengthy incision and extensive soft-tissue dissection. The purpose of this technical note was to describe the details of endoscopic release of the Guyon canal and the pisohamate hiatus. This minimally invasive approach allows release of the ulnar nerve and its motor branch at the wrist level.

Endoscopic Ganglionectomy and Release of the Sixth Extensor Compartment

Stenosing tenosynovitis of the extensor carpi ulnaris is one of the causes of dorsoulnar wrist pain. Conservative treatment is usually effective to alleviate the pain. Surgical release of the retinaculum of the sixth extensor compartment is indicated if conservative treatment cannot alleviate the pain. The purpose of this Technical Note is to describe the technical details of endoscopic release of the sixth extensor compartment via a 2-portal approach. Endoscopic resection of a ganglion over the sixth compartment can also be performed via the same approach.
