Currently, the main factors thought to be associated with outcomes after the repair of peripheral nerve injuries are the age of the patient, mechanism of injury, nerve injured, injury location, defect length, repair time, repair method, operation technique, and repair materials. However, despite numerous studies of outcomes after the repair of peripheral nerve injuries, there is no agreement regarding the independent predictors of a good prognosis, and the dose-effect relationship of the predictors has not been quantified. A study by Dr. Bo He and co-workers from the First Affiliated Hospital of Sun Yat-sen University in China showed that predictors of outcome after the repair of peripheral nerve injuries include age, gender, repair time, repair materials, nerve injured, defect length, and duration of follow-up, and the nerve injured is the main factor affecting the rate of good to excellent recovery. The impact of these predictors on the outcome varies. Functional recovery of peripheral nerve injuries is multifaceted, and different factors may affect outcome in different patients. This study has been reported in the Neural Regeneration Research.
