In which cases is surgery necessary?

Surgery is necessary in most brachial plexus injuries, although the extent of the injury varies depending on each case. Despite being a common treatment for this condition, surgery is not immediate and is rarely recommended within three months of the injury.

The reason for not performing surgery until three months after the injury is that in a small number of cases, recovery occurs spontaneously and surgery is not necessary to improve nerve function. Therefore, surgery is performed in cases where recovery is slow, or in patients who recover incompletely or do not recover at all; it is often performed between three and six months after the injury.

It is important to perform the surgery at the right time, since, after the accident, the muscle may begin to degenerate due to lack of movement and the results of the surgery will not be as expected.
