A broken cervical nerve paralyzes the whole body, if it is partially broken there is a possibility of recovery, if it is completely broken, then it is usually difficult to recover. Cervical spine nerve severance includes two types of nerve partial severance and complete severance, which may lead to general paralysis, paraplegia and so on. If the nerve is partially severed, active and regular treatment can promote nerve repair, which may lead to gradual repair of the severed nerve and normal contraction of the innervated muscles, and the patient has the possibility of recovery. If the cervical nerve is completely broken, it is generally difficult to recover. Because nerve cells are non-renewable cells, even if the severed nerve is successfully sutured through regular treatment, only part of the nerve function can be restored, and it is difficult to fully recover from total body paralysis.
