Hand & Wrist Anatomy
The hand and wrist are comprised of twenty seven bones. There are eight carpal (wrist) bones and nineteen metacarpal and phalanges (bones of the fingers) (Fig.1).
As with all the synovial joints in the body, the carpal, metacarpal and phalanges are covered with hyaline cartilage (Fig.2). This material cushions and provides a smooth surface which permits movement with minimal friction.
