Ulnar carpal tunnel syndrome refers to the symptoms and signs of sensory and motor dysfunction caused by the compression of the ulnar nerve in the ulnar bone fiber canal of the wrist due to various factors. For patients with mild simple sensory disturbance, they can be treated conservatively for the time being, and given local blocking and oral neurotrophic drugs, such as vitamin B1, vitamin B12, mecobalamin tablets, and voltarin tablets. Other cases of ulnar carpal tunnel syndrome should be treated as soon as possible after diagnosis. The shorter the course of the disease, the faster the recovery of nerve function. The operation relieved the fibrous scar and mechanical compression around the nerve, improved the local blood flow barrier of the nerve, promoted nerve fiber regeneration, and restored its normal conduction function. Pay attention to the light diet, eat more fruits and vegetables, and reasonably match the diet.
