Ligaments Intercarpal Interosseous

Intercarpal interosseous ligaments (lat. l. intercarpea interossea) - a group of short ligaments in the wrist area connecting adjacent tarsal bones. There are dorsal and palmar intercarpal interosseous ligaments.

The dorsal intercarpal interosseous ligaments are located on the dorsum of the hand and connect the scaphoid, lunate, triquetrum and pisiform bones.

The palmar intercarpal interosseous ligaments are located on the palmar surface of the hand and connect the trapezius, trapezoid, capitate and hamate bones.

The intercarpal interosseous ligaments stabilize the joints of the hand, limit the mobility of individual tarsal bones, strengthening it as a whole and preventing excessive movement in the joints. Damage to these ligaments can lead to instability and pain in the wrist.

The ligaments between the intercarpal and interosseous are located behind the scaphoid, lunate, triquetrum and pisiform bones, through which it extends in both directions.

The distribution of ligaments from the hand and forearm runs from front to back between the pisiform, triquetral and navicular bones. From the forearm, first between the pisiform-triquetral ligament, and then between the three-layer ligament to the pisiform bone, in which it is located in the thickness of the body of the ligament. Next, between the extensors of the thumb and ring finger, the tendons to the scaphoid bone and passes to the dorsal surface of this bone to the flattened transverse ligament. Laterally - posterior interosseous, then to the bases of the metacarpal bones. Between these bones, ligaments appear:

Ligaments of the metacarpus (a. carpea, mm. flexores carpi): Dorsal interosseous (to the bases of the proximal metacarpal bones, often the lateral ones), two collateral (to the base of the ulnar scrotum and radial bases of the scaphoid bones). Proximal ray of the hand: biceps, hamate, large manifold, palm of five fingers, muscles from wrist to fingers.
