The extensor retinaculum (dorsal carpal ligament, or posterior annular ligament) is a thickened portion of the antebrachial fascia that holds the tendons of the extensor muscles in place. [1] It is located on the back of the forearm , just proximal to the hand . [ 2 ]
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.
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 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 ...
A retinaculum (pl.: retinacula) is a band of thickened deep fascia around tendons that holds them in place. [1] It is not part of any muscle. Its function is mostly to stabilize a tendon. The term retinaculum is Neo-Latin, [2] derived from the Latin verb retinere (to retain). Specific retinacula include: In the wrist: Flexor retinaculum of the hand
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.
Confusingly, the PCL actually corresponds in location and structure to the extensor retinaculum of the hand (located on the opposite side of the wrist) with which the PCL is continuous as both are formations of the antebrachial fascia. Consequently, the flexor retinaculum is commonly referred to as the transverse carpal ligament to avoid confusion.
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.
