What is first dorsal compartment release?
First dorsal compartment release is a surgical procedure that involves releasing the tendon sheath to relieve the constriction of the tendons as they pass though the sheath. During the procedure, an incision is made just below the tip of the radial styloid, and the first dorsal compartment is opened.
Where is the first dorsal compartment?
wrist
The first dorsal compartment of the wrist includes the tendon sheath that encloses the abductor pollicis longus and the extensor pollicis brevis tendons at the lateral border of the anatomic snuffbox. The Finkelstein test is performed by having the patient make a fist with the thumb inside the fingers.
What is the first extensor compartment?
Structure
| Compartment | Component(s) |
|---|---|
| 1 | Abductor pollicis longus tendon Extensor pollicis brevis tendon |
| 2 | Extensor carpi radialis longus tendon Extensor carpi radialis brevis tendon |
| 3 | Extensor pollicis longus tendon |
| 4 | Extensor digitorum tendons Extensor indicis tendon |
What is the first dorsal?
The first dorsal interosseous muscle is larger than the others. Between its two heads, the radial artery passes from the back of the hand into the palm. Between the heads of dorsal interossei two, three, and four, a perforating branch from the deep palmar arch is transmitted.
What is positive Finkelstein test?
This test is positive if the patient reports pain aggravation at the tip of the radial styloid process. If this step does not elicit pain, the examiner can gently apply an ulnar deviation force to the hand which results in an increased passive stretch across the first dorsal compartment.
What are the 6 extensor tunnels?
Radial wrist abductor (abductor pollicis longus tendon) and thumb extensor (extensor pollicis brevis tendon) dorsal to the trapezium bone. Radial wrist extensors (extensor carpi radialis longus and ECRB tendons) dorsal and radial to the trapezoid bone. Extensor pollicis longus tendon.
What is extensor compartment release?
Surgery to correct De Quervain’s tenosynovitis is called a 1st Extensor Compartment Release. This involves a small incision over the thumb side of the wrist to access and release the 1st Extensor Compartment that is entrapped the EPB and APL tendons, causing pain and difficulty with movement.
What is the second extensor compartment?
The second dorsal compartment of the wrist is comprised of the extensor carpi radialis brevis (ECRB) and extensor carpi radialis longus (ECRL).[1][2][4]
What is 1st dorsal interosseous?
The first dorsal interosseous muscle has its origin on the adjacent surfaces of the first and second metacarpal bones and inserts into the lateral base of the second phalanx and extensor hood of the second digit.
When is release of the first dorsal compartment indicated?
Release of the First Dorsal Compartment. Surgical release of the first dorsal compartment is indicated following failure of conservative treatment of de Quervain disease. Initially, patients are treated by a trial of splinting and corticosteroid injection of the first dorsal compartment.
What are the anesthesia options for dorsal compartment release surgery?
Anesthesia Options. First dorsal compartment release surgery can be performed with or without sedation: Awake during surgery (no sedation): About 20-30 minutes prior to the procedure, local anesthesia will be injected into the affected hand. This provides adequate time for the surrounded area to absorb the anesthetic.
What are the treatment options for first dorsal compression syndrome (DRS)?
Initially, patients are treated by a trial of splinting and corticosteroid injection of the first dorsal compartment. Repeat trials of nonoperative treatment, including up to three injections, are occasionally indicated.
What does the first dorsal extensor compartment contain?
The first dorsal extensor compartment contains the abductor pollicis longus (APL) and the extensor pollicis brevis (EPB) tendons.
