Any of the dorsal compartments of the wrist can develop tenosynovial inflammation. [3] The first compartment is the most frequently affected site, called De Quervain's disease (syndrome or tenosynovitis). The other two most commonly injured are the sixth (extensor carpi ulnaris) and second (intersection syndrome) compartments.
The extensor indicis proprius usually runs and inserts onto the ulnar side of the extensor digitorum communis of the index finger. [4] The fifth compartment is occupied by the extensor digiti minimi, the extensor of the little finger. The extensor carpi ulnaris passes through the sixth compartment to insert to the base of the fifth metacarpal bone.

The mobile wad (or mobile wad of Henry) is a group of the following three muscles found in the lateral compartment of the forearm: [1] brachioradialis; extensor carpi radialis brevis; extensor carpi radialis longus; It is also sometimes known as the "wad of three", [2] "lateral compartment", [3] or "radial group" [4] of the forearm.
Moving distally, there are the abductor pollicis longus (APL), extensor pollicis brevis (EPB), extensor pollicis longus (EPL), and extensor indicis (EI). The APL originates from the lateral part of the dorsal surface of the body of the ulna below the insertion of the anconeus and from the middle third of the dorsal surface of the body of the ...
Between the dorsal carpal ligament and the bones six compartments are formed for the passage of tendons, each compartment having a separate mucous sheath. One is found in each of the following positions: on the lateral side of the radial styloid process, for the tendons of the Abductor pollicis longus and Extensor pollicis brevis;
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 most important signs and symptoms of compartment syndrome are observable before actual contracture. What is known as the five Ps of compartment syndrome include: pain, generally the initial symptom, accompanied by pulselessness, pallor, paralysis, and paraesthesias. Pain will likely also increase upon extension of the affected limbs hands ...
