An elbow disorder characterized by direct trauma to the ulnar nerve in the cubital tunnel (a groove behind the elbow), repetitive elbow flexion, hypermobility of the ulnar nerve, and a loose body impingement of the ulnar nerve. The disorder is characterized by aching posteromedial elbow pain, a feeling of ‘pins and needles’ in the arm, weakness of the thumb-index finger pinch, pain with forced elbow flexion, and, in chronic cases, wasting of the intrinsic musculature of the hand. Treatment includes rest, anti-inflammatories, elbow protection, and (for golfers, weight-lifters and racket players who share the disorder) a change in technique. Severe cases may require surgical decompression and transposition of the ulnar nerve.
