An injury to the wrist involving roughening of the articular cartilage (a chondromalacia between the pisiform and triquetral bones (thepiso-triquetral joint). It is thought to be due to repeated torsional stresses on the piso-triquetral joint by sharp and powerful supination-pronation movements performed by racquet players. The condition appears to be more common among squash and badminton players, who use a lot of wrist action, than among tennis players who tend to make strokes using the shoulder. Golfers may also sustain a similar condition.
