How long it takes to recover from a finger nerve break varies from person to person and is closely related to the extent of the break and the outcome of the treatment. Normally, if there is no defect at the end of the severed nerve, it can be sutured end-to-end directly and fixed in a cast for about 3-4 weeks after surgery, with recovery occurring in about 4-5 weeks. If the severely contaminated nerve of the severed finger, or if there is a defect due to old injury, etc., a nerve graft is usually required and the recovery time will be relatively longer, about 3 months. It should be noted that the recovery time after nerve rupture is somewhat uncertain, even if the surgeon does a good job of nerve suturing or nerve release, the exact recovery time of nerve function or whether it can be fully restored depends on the growth of the nerve, the atrophy of the hand muscles, etc. After hand nerve rupture surgery, if the patient has local skin numbness and motor incompetence, he/she should follow up with the hand surgery or surgery department of the hospital in a timely manner, and carry out hand rehabilitation training at the right time and in the right amount according to medical advice, together with the use of nerve-nourishing drugs for comprehensive treatment.
