Reconstruction of Upper Extremity Peripheral Nerve Injuries Using an Epineurial-Like Collagen Device—A Prospective Clinical Study

Background Epineurium acts as a barrier to protect nerves from injury and maintains its structural and functional integrity. A device was developed to mimic the native structure of epineurium. The aim of this study was to evaluate its biological characteristics and clinical performance in the reconstruction of upper extremity peripheral nerves.
