Carpal Index: Definition And Clinical Significance

• Carpal bones were fist named by Lyser in 1683.
• Carpals are the bones in hand-wrist region.
• Carpals are the multiple small bones in hand-wrist region. Carplals follow a pattern in ossification along with union of epiphysis and diaphysis.
• For carpal index left hand-wrist region is used.
• PA view is taken to record the hand-wrist region.
• Each hand-wrist region has 8 carpals, 5 metacarpals, 14 phalanges which form total 27 bones.
• Carpal bones are arranged in distal and proximal rows. Distal row consists of trapezium, trapezoid, capitate, hamate; Proximal row consists of scaphoid, lunate, triquetral, pisiform.
• The above irregular bones lie between long bones of forearm and metacarpals.
• Each of the carpal bone ossifies from one primary center which appears in a particular predictable pattern.
