Fast and accurate distal locking of interlocked intramedullary nails using computer-vision and a 3D printed device.

Introduction: Distal locking is a challenging and time-consuming step in interlocked intramedullary nailing of long bone fractures. Current methods have limitations in terms of simplicity, universality, accuracy, speed, and safety. We propose a novel device and software for distal locking using computer vision.
