The ulnar artery and nerve are in immediate relation with the lateral side of the bone. Greater Multangular ( Trapezium).—The greater mult- angular is the most lateral bone of the distal row of the carpus. It may be readily recognised by the oval saddle-sb aped facet on its distal surface for articulation with the metacarpal bone of the thumb. From its volar aspect there rises a prominent ridge, medial to which is a groove along which the tendon of the flexor carpi radialis muscle passes. The ridge furnishes an attachment for the transverse carpal ligament, as well as for some of the short muscles of the thumb. The proximal surface has a half oval facet for the navicular, lateral to which it is rough, and becomes fig. 213—The Eight Naviculak Boke. continuous with the non-articular NOTK-The bone is; represented in the: centre of the figure M j , M h ^^ f m the position which it occupies in the right hand viewed r > , from the volar aspect.

The oshamatum dorsal surface, of irregular outline, is rough for the attach- ment of ligaments. The greater multangular articulates with four bones, the navicular, lesser multangular, and the first and second metacarpal bones. Lesser Multangular ( Trapezoid Bone).—With the exception of the pisiform, this is the smallest of the carpal bones. Its rough volar sur- face is small and pentagonal
