概要

Background: Three dimensional (3D) digital pre-operative planning software for osteosynthesis of fractures was developed. To assess the usefulness of the 3D planning, we evaluated the accuracy of the reduction shapes and selected implants in the patients with distal radius fractures. Methods: Thirty wrists of 30 distal radius fracture patients who underwent osteosynthesis using volar locking plates were evaluated. Fifteen wrists were treated with 3D preoperative planning as the plan group. The other fifteen wrists were treated with conventional preoperative planning as the control group. Volar tilt and radial inclination were measured after operation and compared with the healthy side wrist. In addition, preoperative planning and postoperative reductions were compared by measuring the volar tilt and radial inclination of the 3D images in the plan group. The intra-class correlation coefficient (ICC) values of the radiological parameters between healthy side wrists and injured side wrists, between preoperative planning and postoperative reductions were evaluated. For the accuracy of the implant choices, the ICCs for the screw lengths between the preoperative plan and the actual choices were evaluated in the plan group.
