Ligaments of wrist. Posterior view. (Dorsal intercarpal ligaments labeled at center left.) ... The dorsal intercarpal ligament consists of a series of fibrous bands ...
There are four groups of ligaments in the region of the wrist: [8] The ligaments of the wrist proper which unite the ulna and radius with the carpus: the ulnar and radial collateral ligaments; the palmar and dorsal radiocarpal ligaments; and the palmar ulnocarpal ligament. (Shown in blue in the figure.)
The dorsal intercarpal ligament are two in number and placed transversely behind the bones of the first row; they connect the scaphoid and lunate, and the lunate and triquetrum. The palmar intercarpal ligaments are also two, connect the scaphoid and lunate, and the lunate and triangular; they are less strong than the dorsal, and placed very ...
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 .
On the dorsal side of the hand, the palmar carpal ligament corresponds in location and structure to the extensor retinaculum, both being formations of the antebrachial fascia and therefore continuous. Consequently, the flexor retinaculum is commonly referred to as the transverse carpal ligament to avoid confusion. [4]
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.

The joints in the hand are joints found at the distal end of the upper limb.. The joints are: In the wrist there is the radiocarpal joint between the radius and carpus.Between the carpal bones are the intercarpal articulations and the midcarpal joint.
