How to treat carpal tunnel syndrome

If carpal tunnel syndrome occurs, the only way is to quickly control the development of the disease through some treatment methods. Many patients will use surgical treatment measures to relieve the disease when it just begins to develop, but in fact, many times the use of non-surgical methods can achieve the same effect and will not cause serious harm. Many surgical methods will leave very serious sequelae to the patient's body after the operation.

Disease treatment

Nonsurgical treatment

There are many non-surgical treatments for carpal tunnel syndrome, including bracing and corticosteroid injections.

Doctors often recommend that patients use braces to control the progression of the disease and relieve symptoms. Commonly used are prefabricated braces, which control the wrist joint in a 30-degree dorsiflexion position after wearing. However, this dorsiflexion angle will increase the pressure in the carpal tunnel. Studies have shown that patients with carpal tunnel syndrome have increased pressure in the carpal tunnel, and the pressure increases further when the wrist joint is extended. The most effective position for controlling symptoms is neutral. Fixing the wrist joint in a neutral position can reduce the pressure in the carpal tunnel, but the wrist joint position that is most conducive to the function of the hand is 30 degrees of dorsiflexion. Considering that the neutral position is not conducive to the performance of manual functions, the general recommendation is not to fix the wrist in the neutral position during the day and to use a brace to fix the wrist joint in the neutral position at night.

Oral anti-inflammatory drugs and local injection of corticosteroids are also commonly used methods, with varying success rates reported in the literature. Celiker et al. compared the efficacy of corticosteroid injection and nonsteroidal anti-inflammatory drugs combined with brace immobilization through a randomized controlled study. The results showed that the symptoms of both groups of patients were significantly improved. However, since the follow-up was only 8 weeks, the conclusion is not convincing enough. Edgell et al. and Green both believe that if local injection can temporarily relieve symptoms, the success rate of surgery is high. There are also literature reports that hormone injections have complications, such as damage to the median nerve. Studies in rodent experimental models have shown that even if dexamethasone is injected directly into the nerves, it will not damage the nerves. All other steroid drugs damaged the nerve when injected into the rats' sciatic nerve. Therefore, although corticosteroid injections may provide temporary relief of symptoms, they are not recommended for routine use [7].

Surgery

If conservative treatment options fail to relieve the patient's symptoms, surgical treatment should be considered. In 1924, Herbert Galloway performed the first carpal tunnel release surgery. After that, a variety of surgical methods emerged, including various incision surgeries, small incision decompression and endoscopic surgery. Although the goal of surgery is to release the median nerve, it is possible that one or even several median nerves may be injured due to iatrogenic causes. Therefore, no matter which surgical method is preferred, it should be based on the premise that the median nerve can be fully exposed to avoid nerve injury. For patients with damaged wrist structures, space-occupying lesions, synovial lesions, and those who need secondary release and decompression, it is best to perform open release and decompression, and the incision should be long so that additional surgery can be performed. When problems arise when using a short incision, such as difficulty in operation or difficulty in seeing directly, the incision should be extended, changing the short incision into a long incision to avoid accidents.
