Case Discussion

Intersection syndrome is a painful "friction" condition that affects the thumb side of the forearm when inflammation occurs at the intersection of the musclo-tendinous junctions of the abductor pollicis longus and extensor pollicis brevis as they cross over the extensor carpi radialis longus and the extensor carpi radialis brevis tendons. The mechanism of injury is usually repetitive resisted extension, as with rowing, weight lifting, or pulling. Intersection syndrome is often confused with DeQuervain's tenosynovitis that occurs more distally at the wrist rather than forearm.
