The hand is broad with short metacarpals and phalanges, and a trident configuration. Blunted metacarpals (particularly the fourth metacarpal) are a symptom of Nevoid basal cell carcinoma syndrome. As metapodials, the metacarpals and metatarsals are analogous to each other. Among themselves, the four ulnar metacarpals also articulates with their neighbours at the intermetacarpal articulations. Each human hand has five metacarpals and eight carpal bones. The most common sites for fractures are the nose, carpal bones, metacarpals, digits, and ribs. No wrist bones existed, with the four palm bones (metacarpals) attaching directly to the forearm. First, the proximal row is removed and the distal row is fastened to the metacarpals. As these two metacarpals approach each other, the palmar gutter deepens. Wrist bones and the metacarpals are fused into a carpometacarpus. She fractured her radius, two metacarpals and two fingers in her right arm and hand. When standing, pterosaurs probably rested on their metacarpals, with the outer wing folded to behind. Its more typical "rhamphorhynchoid" characters include its elongated fifth toe and short metacarpals and neck. In this position, the "anterior" sides of the metacarpals were rotated to the rear. The base is significantly different from the bases of the other metacarpals.
