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.
A myotome is the group of muscles that a single spinal nerve innervates. [1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum). [2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.
The cysts may intrude into the spine, which may cause pain and dysesthesia in distant extremities. [ 20 ] Cystic adventitial disease , in which a cyst occurs within the popliteal artery near the knee, has been proposed recently to occur by an articular mechanism, with a conduit leading from the joint, similar to the development of ganglion ...
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]
Wrist drop is a medical condition in which the wrist and the fingers cannot extend at the metacarpophalangeal joints. The wrist remains partially flexed due to an opposing action of flexor muscles of the forearm. As a result, the extensor muscles in the posterior compartment remain paralyzed.
[10] [11] [12] Other underlying disorders include vasculitides such as polyarteritis nodosa. [8] Other causes of edema include heart failure, hypoalbuminemia, nephrotic syndrome and venous stasis. The key distinguishing feature is that these conditions don't tend to manifest with pitting edema at the back of the hands.
Humerus at the anterior of lateral epicondyle (common extensor tendon) [1] Insertion: Posterior base of the 3rd metacarpal [1] Artery: Radial artery: Nerve: Deep branch of the radial nerve: Actions: Extensor and abductor of the hand at the wrist joint [1] Antagonist: Flexor carpi ulnaris muscle: Identifiers; Latin: musculus extensor carpi ...
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.
