The dorsal radiocarpal ligament (posterior ligament) is less thick and strong than its volar counterpart, and has a proximal attachment to the posterior border of the distal radius. Its fibers run medially and inferiorly to form a distal attachment at the dorsal surfaces of the scaphoid (navicular bone of the hand), lunate, and triquetral.
Dorsal rotation injury, such as when a drill binds and rotates the wrist instead of the bit, can also cause traumatic injuries. Injury may also occur from a distraction force applied to the volar forearm or wrist. Finally, tears of the TFCC are frequently found by patients with distal radius fractures. [7]
The articular joint's surface must be smooth for it to function properly. Irregularity may result in radiocarpal arthritis, pain, and stiffness. More than 1 mm of incongruity places the patient at a high risk for post-traumatic arthritis. Significant articular incongruity typically occurs in young patients after high energy injuries.
Wrist arthroscopy can be used to look inside the joint of the wrist. It is a minimally invasive technique which can be utilized for diagnostic purposes as well as for therapeutic interventions. Wrist arthroscopy has been used for diagnostic purposes since it was first introduced in 1979. However, it only became accepted as diagnostic tool ...
The interosseous intercarpal ligaments are two narrow bundles, one connecting the lunate with the scaphoid, the other joining it to the triangular. They are on a level with the superior surfaces of these bones, and their upper surfaces are smooth, and form part of the convex articular surface of the wrist-joint. The ligaments connecting the ...

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 ]
The dorsal intercarpal ligament consists of a series of fibrous bands that extend transversely across the dorsal surfaces of the carpal bones, connecting them to each other. v t
