Nerves transmit the impulses from brain and spinal cord to peripheral organs and entrapment or compression of the nerves, often at tunnel regions, may cause nerve compression syndrome. Nerves often susceptible for compression include the median nerve in the wrist, ulnar nerve at elbow, and radial nerve in proximal forearm. Compression of these nerved cause carpal tunnel syndrome, cubital tunnel syndrome, and radial tunnel syndrome, respectively.
Cubital tunnel syndrome: It is the condition often caused by more pressure on elbow or by prolonged and excessive flexion of elbow and the risk is more in individuals who play basketball. Cubital tunnel syndrome causes numbness and tingling sensation in the ring finger and little finger and severe elbow pain. If the condition is severe, patient may suffer weakness of muscles of hand and may experience pinch between thumb and index finger and poor hand grip.
Radial tunnel syndrome: Radial tunnel syndrome can be caused by trauma, ganglia, lipomas, bone tumors, or elbow synovitis. Radial tunnel syndrome may cause lancinating pain in forearm and elbow which may be aggravated when wrist and fingers are extended.
Compression syndromes can be diagnosed by patient history, medical history, imaging techniques and nerve conduction studies.
Nerve compression syndromes are treated by non-steroidal anti-inflammatory drugs, corticosteroids or with neurosurgery.
