Cubital Tunnel Syndrome  And Nerve Injuries - Teaching Video

This film presents injuries of the various nerves, damage palsy including radial and ulnar nerve, cubital and tarsal tunnel syndromes. The nerves takes onset from the spinal cord providing motor and sensory function. If the injury occurs to the long thoracic nerve, that causes medial winging of the scapula. If the axillary nerve is damaged due to dislocation of the shoulder, it results in weakness of abduction of the shoulder. If the anterior interosseus nerve is injured, the patient is not able to do the O.K. gesture. Extension of the finger is not possible in posterior interosseus nerve injury, in the case of Montaggia fractures. However, the patient can still extend the wrist. The wrist drop appears in cases of patients with radial nerve palsy, in the distal third of humeral fractures. In the case of median nerve compression, the patients can have stiffness in the lateral three digits with positive Phalen's and Tinel test. The patients with ulnar nerve injury or squezze in cubital tunnel syndrome shows positive Froment's test. In low ulnar nerve injury, the clawing of the hand appears. Release or transposition of the ulnar nerve may be needed to relieve impingement. The quadiceps muscle, which extends the knee is supplied by the femoral nerve. The ischiatic nerve is divided into the common peroneal nerve, which when injured leads to foot drop. The other branch is called a tibial nerve, which if damaged leads to a numbness of the foot. Observation, surgery, decompression or repair are treatment methods of peripheral nerve injury, carpal tunnel syndrome, cubital and tarsal tunnel.
