The benefits from the first shot only lasted 2 weeks. The second and third set of injections lasted about 90 days. In November, I was ready to have surgery. My EMG and nerve conduction tests proved that the nerves were "sleeping" before I was. After another MRI, the neurosurgeon said I was a candidate for surgery but I was not able to get the endoscopic type surgery that is less invasive. I would have an incision about 6-8" long. Along with removing the herniation, they would have to increase the size of the hole where the nerve roots were going through.
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.
