Intersection Syndrome

Excerpt

Intersection syndrome is a condition that affects the first and second compartments of the dorsal wrist extensors. The condition is thought to occur due to repetitive friction at the junction in which the tendons of the first dorsal compartment cross over the second, creating tenosynovitis. The patient experiences pain just proximal and dorsal to the radial styloid or 4 to 6 cm proximally to the Lister tubercle.
