Any movement of the thumb and wrist causes the patient pain, inflammation and swelling. The presence of anomalous or variant muscles in the fourth compartment may result in chronic dorsal wrist pain, a condition known as the fourth compartment syndrome. [4] Intersection syndrome can be caused by direct trauma to the second extensor compartment.
Dorsal Radial portals The portals lay between the dorsal extensor compartments. [17] 1-2 portal: Between the 1st and 2nd extensor compartments; Located in the Anatomical snuff box; not often utilized; 3-4 portal: between the 3rd and 4th extensor compartments; Located distal to Lister's tubercle; primary viewing portal; 4-5 portal:
The second compartment is occupied by the two radial wrist extensors, the extensor carpi radialis longus and the extensor carpi radialis brevis. The third compartment exclusively accommodates the extensor pollicis longus, which hooks around Lister's tubercle of radius and inserts to the thumb. The fourth compartment is the largest of all.
Extensor digitorum brevis manus is an extra or accessory muscle on the backside (dorsum) of the hand. It was first described by Albinus in 1758. [1] The muscles lies in the fourth extensor compartment of the wrist, and is relatively rare. [2] It has a prevalence of 4% in the general population according to a meta-analysis. [3]
Extensor compartments of wrist (back of hand) The fingers have two long flexors, located on the underside of the forearm. They insert by tendons to the phalanges of the fingers. The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx. The flexors allow for the actual bending of the fingers.
The first dorsal interosseous, the most consistent, is inserted entirely into the base of its proximal phalanx and the extensor hood there. The second, third, and fourth dorsal interossei have insertions both proximally on the base of the metacarpal and hood, and distally on the lateral bands and central tendon of the extensor mechanism.
Here’s how to get rid of chest congestion medically and naturally, according to experts.
There are six separate synovial sheaths run beneath the extensor retinaculum: (1st) abductor pollicis longus and extensor pollicis brevis tendons, (2nd) extensor carpi radialis longus and brevis tendons, (3rd) extensor pollicis longus tendon, (4th) extensor digitorium communis and extensor indicis proprius tendons, (5th) extensor digiti minimi tendon and (6th) extensor carpi ulnaris tendon.
