Synopsis

Causes / typical injury mechanism: Pain at the second dorsal compartment of the wrist. The involved tendons include the extensor carpi radialis brevis and the extensor carpi radialis longus.

Classic history and presentation: Common in athletes, particularly rowers and skiers. It is more common in athletes starting a new sport.

Prevalence: Prevalence is approximately 0.2% to 0.37%. The dominant hand is more commonly affected.

Pathophysiology: The disease is characterized by rubbing of the first dorsal compartment muscles on the second compartment tendon sheaths in the region where the compartments intersect. There is debate as to whether this condition is predominantly degenerative versus inflammatory in nature.
