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.
One uncommon location of the cysts are in the muscle tendons of the hand, such as the extensor digitorum superficialis. [ 22 ] Cysts that were compressing one or more nerves and causing bone erosions have been reported to occur near the shoulder joint .
Extensor tendons pass through the extensor retinaculum at wrist joint in 6 synovial sheaths, also referred to compartments. [3] The supinator and the anconeus are the two extensor muscles in the posterior compartment of the forearm that do not pass through wrist extensor compartments. [3]
The chief complaint of this disease is usually pain in the dorsal aspect of the upper forearm, and any weakness described is secondary to the pain. Tenderness to palpation occurs over the area of the radial neck. Also, the disease can be diagnosed by a positive "middle finger test", where resisted middle finger extension produces pain.
The anterior interosseous nerve is a branch of the median nerve, with a large sensory branch to the wrist bones, which arises just below the elbow. It passes distally, anteriorly along the interosseous membrane and innervates flexor pollicis longus, flexor digitorum profundus to index and middle finger as well as pronator quadratus, and supplies sensory feedback from the wrist bones, i.e. the ...
A dorsal tilt of 10 to 15 degrees is considered normal. [18] Wrist pain has a number of causes, including carpal tunnel syndrome, [16] ganglion cyst, [19] tendinitis, [20] and osteoarthritis. Tests such as Phalen's test involve palmarflexion at the wrist. The hand may deviate at the wrist in some conditions, such as rheumatoid arthritis.
The mechanism of injury is usually repetitive resisted extension, as with rowing, weight lifting, or pulling. [citation needed] Intersection syndrome is often confused with another condition called DeQuervain's syndrome, which is an irritation of the thumb-sided set of tendons at the wrist, called the first dorsal compartment.
An illustration of wrist pain. Wrist pain or open wrist is a syndrome inhibiting use of a hand due to pain in anatomical structures of the wrist. [1] It most commonly results from an injury to a ligament. [1] The pain may be sharp from a traumatic injury or from chronic repetitive wrist activities. [1]
