The Hand & Wrist
The hand and wrist are important and complex areas of the body used frequently in our day-to-day activities. Hands are the main structures for physically manipulating the environment, used for both gross motor skills (such as grasping a large object) and fine motor skills (such as picking up a small coin). The fingertips contain some of the densest areas of nerve endings on the body, are the richest source of tactile feedback, and have the greatest positioning capability of the body; thus the sense of touch is intimately associated with hands. Injuries to the hands and wrists are common and at OSC, our specialists are experts at identifying treatments and conducting procedures that allow patients to regain mobility and get back to activity.
Hand: The human hand has 27 bones, not including the sesamoid bones which number varies between people. 14 of which are the phalanges which make up the fingers. There are 5 metacarpals, or bones that connect the fingers and the wrist and 8 carpal bones.
Wrist: In human anatomy, the wrist is variously defined as 1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus; and (3) the anatomical region surrounding the carpus including the distal parts of the bones of the forearm and the proximal parts of the metacarpus or five metacarpal bones and the series of joints between these bones, thus referred to as wrist joints.
