Case of a wrist laceration after a fall while holding a glass. Patient came to ER with loss of feeling to her thumb and index finger. She could not move thumb, index and third finger. Closer examination revealed a lacerated median nerve along with several flexor tendons. Tendons and the median nerve were sutured (the cut median nerve is seen being held with forceps).
The median nerve is the main nerve of the front of the forearm. It innervates all of the flexors in the forearm except flexor carpi ulnaris and that part of flexor digitorum profundus that supplies the fourth and fifth digits. The latter two muscles are supplied by the ulnar nerve. The median nerve innervates the skin of the palmar (volar) side of the index finger, thumb, middle finger, and half the ring finger, and the nail bed.
Injury of median nerve at different levels causes different syndromes with varying motor and sensory deficits. Injury at the wrist level- Motor deficit:
-Weakness in flexion of radial half of digits and thumb, loss of abduction and opposition of thumb
-Presence of an ape hand deformity when the hand is at rest may be likely, due to an hyperextension of index finger and thumb, and an adducted thumb. Nevertheless, an ape hand deformity is not a requirement for a carpal tunnel syndrome diagnosis.
-Presence of a benediction sign when attempting to form a fist, due to weakness in flexion of radial half of digits
Sensory deficit:
- Loss of sensation in lateral 3 1/2 digits including their nail beds, and the thenar area.
