What is Examination of the Peripheral Nerves in the Hand and Upper Limb about?

## A. History B. Clinical Examination Step1 Look Step 2 Quick screen of nerves ## Step 3 Feel Step 4 Move Step 5 (Provocation tests if necessary) After inspection, a quick screen for assessing the peripheral nerves to the hand may be useful. This might be especially so in children. It can also provide a further clue as to which peripheral nerve it will be best to examine first. Ask the patient to 'point your finger' (radial nerve), 'cross your fingers' (ulnar nerve), 'make an "O"' (median nerve). ## Provocation Tinel's sign Elbow flexion test Differentiation between high and low lesions can also be suspected on inspection. In lower lesions the clawing is much more pronounced than in high ulnar nerve lesions (due to the loss of the FDP to the little and ring fingers in the high lesion). This is called the ulnar paradox. In high ulnar nerve palsy, such as injury around the medial epicondyle, sensation in both areas is affected, whereas in low ulnar nerve problems, such as compression in Guyon's canal, the dorsal branch is preserved, resulting in no loss of sensation in the region of the fifth metacarpal. In a high ulnar nerve lesion the motor power in all muscle groups is affected an
