Abstract

This invention is a method and tool for measuring and correcting deformities during osteotomy and treatment of fractures. The tool designed to restoring, alignment and correcting deformities of bone and joints is based on preoperative imaging and calculation of the deformity angle and planning for the deformity correction, the tool has a mechanism and power to force the bone to move according to the planning trajectory aiming at normal alignment during osteotomy and treatment of fracture and dislocation, it has a gauge to measure the degree of correction and the value of the bone displacement needed to overcome the bone overlapping and deformity angle in the fracture zone.
