A new device for nerve approximation in traumatic injuries of extremities

Background Precise approximation of two nerve endings is a major determinant of outcomes following nerve repairs. Despite technical and instrumental advances, approximation of nerve endings remains a challenge in reconstructive surgeries. We designed a new nerve approximator device for precise approximation of nerve endings and evaluated its utility in surgeries of peripheral nerves. Methods We conducted a longitudinal study comparing postoperative functional outcomes between patients with peripheral nerve injury undergoing surgical repair by the new approximator device and conventional technique. Results A total of 204 nerve trunks were repaired by the new approximator device and 91 nerves by conventional technique. Patients were followed for a median of 30 months. Time required for nerve approximation was significantly reduced with the approximator device (4.5 min vs. 7 min, p
