DESCRIPTION: These can be divided into two groups- the first consist of the proximal intercarpal joints which is between the bones of the proximal row of carpus- scaphoid, lunate and triquetral. And the second being the articulations between the distal row of carpal bones, which are trapezium, trapezoid, capitate and hamate.
· Extension: All the extensor tendons that cross the wrist joint participate in extending that joint. The main extensors are the extensor carpi radialis longus, extensor carpi radialis brevis and the extensor carpi ulnaris, assisted by extensor digitorum, extensor indicis, extensor digiti minimi and extensor pollicis longus.
