The recovery time of radial nerve injury is related to the degree of injury, location, and injury factors, and the recovery time varies from case to case and cannot be generalized. The radial nerve is one of the most vulnerable peripheral nerves in the brachial plexus nerve to trauma. There are more injury factors, such as inflammation, trauma, mid-humeral fracture, lead, arsenic, alcohol poisoning, and pressure during sleep or axillary crutches. If the distance of injury is short, it can be treated by taking nerve-nourishing drugs under the guidance of a doctor, and the nerve extends at a rate of about 1 mm per day; remove the factors that caused the injury. If it is completely broken and the injury is severe, the nerve damage needs to be repaired first, and the recovery time will be prolonged, which may be about 6-8 weeks for the fast ones and 2-3 months for some. It is important to note that traumatic radial nerve injury requires prompt surgical intervention, preferably within 6-8 hours of suture fixation of the nerve.
