Treatment depends on several factors, including the severity of the injury, the type of injury, the length of time since the injury and other existing conditions.
Nerves that have only been stretched may recover without further treatment.
Your provider may recommend physical therapy to keep the joints and muscles working properly, maintain range of motion, and prevent stiff joints.
Surgery to repair brachial plexus nerves should generally occur within six months after the injury. Surgeries that occur later than that have lower success rates.
Nerve tissue grows slowly, so it can take several years to know the full benefit of surgery. During the recovery period, you must keep your joints flexible with a program of exercises. Splints may be used to keep the hand from curling inward.
