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.
By using a high frequency ultrasound probe the wrist is imaged by placing the probe transverse across dorsiflexed wrist. The median nerve and ulnar artery is identified. At the level of the distal wrist crease, the needle is passed into the skin superficial to the ulnar artery, penetrating the flexor retinaculum. The needle is advanced toward the median nerve. The steroid solution is injected just under the flexor retinaculum then retracted and redirected deeper to the ulnar side of the median nerve. This allows the median nerve to be completely surrounded with the steroid solution. [ 3 ]
