[Stenosing tendovaginitis of the flexor carpi radialis tendon].

Pain at the radial side of the wrist may be caused by stenosing tenosynovitis of the flexor carpi radialis tendon. Typical in these cases is a tenderness over the tendon at the wrist. Pain is most often produced by pronation and especially by palmar flexion against resistance. The condition is caused by narrowing of the canal of flexor carpi radialis tendon within the wrist by nonspecific synovitis. In some cases osteoarthritis of the joint between the scaphoid and trapezium can compress the tendon and cause its attrition. If the pain is not relieved by conservative methods it can usually be cured by operative decompression of the canal.
