Distal Intersection Syndrome Combined With Partial Attritional Changes of the Extensor Carpi Radialis Brevis in Tennis Players

The purpose of this study is to report the cases of 2 tennis players with distal intersection syndrome, a rare pathological condition, combined with partial attritional changes of the extensor carpi radialis brevis tendon. Both individuals were able to return to their original level of performance after surgical intervention consisting of synovectomy within the distal intersection and release of the distal part of the extensor retinaculum. Physicians should familiarize themselves with distal intersection syndrome, which can cause dorsoradial wrist pain in tennis players. If pain is prolonged, tendon attrition may occur, and surgical treatment may be indicated.
