Intersection Syndrome of the Wrist

摘要

A right-hand-dominant elite golfer in her mid-twenties reported a 3-month history of left forearm pain; 2 months previously, she had undergone an injection of steroids for De Quervain's tenosynovitis. On examination 2 months following injection, swelling was observed on the radial side of the distal forearm proximal to the radial styloid. Finkelstein's test (ulnar deviation of the hand while the thumb is flexed) was mildly positive. Magnetic resonance imaging (MRI) of the wrist showed subcutaneous edema and tenosynovitis at the crossover point of the first and second dorsal extensor compartments (Figure 1).
