A pooled quantitative literature search concerning the treatment of de Quervain’s tenosynovitis compared 7 studies (a total of 459 wrists) with identical diagnostic and success criteria. 4 Average follow-up was months (range, 1 week to 7 years). There were no control groups in the studies, and none of the studies were randomized. Of the 226 cases treated with steroid injection alone, 83% were cured, though 30 of these needed a second injection. Sixty-one percent of those treated with injection and splint were cured, while 14% treated with splint alone reported cure.
