Examination of the Wrist and Hand
The attitude of the hand is noticed when the normal hand is held in slight flexion at the metacarpophalangeal and interphalangeal joints. One finger may be extended when the flexor tendon is damaged or cut in that finger. It is important to count the number of the fingers initially as it may be increased in congenital anomalies. Normal movements of the hand are smooth and synchronous. Sometimes these may be jerky and in some cases may be compensated by movements of the elbow and the shoulder joint.
