Objective: Clinical application of 3D printing implant in bone defect treatment.
Study design: multicenter randomized controlled study . Methods:patients randomly grouped according to register number into internal fixation and bone graft group and 3D printing group. Reconstruct 3D models ,evaluate models preoperatively , simulate surgery in computer,design 3D implant, and 3D print implants,perform surgery with 3D implants to achieve the greatest degree of physiological reconstruction.Evaluate surgical efficacy .
