Three-dimensional digital design of orthopedic surgery for idiopathic scoliosis deformity: A case series.

Abstract

ObjectiveTo establish a new method of three-dimensional digital design for orthopedic surgery of idiopathic scoliosis deformity and evaluate its application value in surgical treatment.MethodsThe clinical data of 11 patients with idiopathic scoliosis who underwent three-dimensional digital design and three-dimensional printing from January 2021 to December 2023 were retrospectively analyzed. Patients underwent computed tomography at admission, and three-dimensional reconstruction of a spinal anatomy model was conducted. Three-dimensional digital design of deformity correction surgery was conducted before the operation, including computer simulation of the correction and internal fixation process and three-dimensional digital design of a pedicle screw-assisted positioning template and internal fixation rod template. Surgical procedures were performed accurately under template guidance.ResultsThe average preoperative Cobb angle in 11 patients with idiopathic scoliosis was 50.2°. The pedicle screws were implanted accurately and quickly. The average operation time was 4.2 h, and the average blood loss was 810 mL. The postoperative deformity correction was very satisfactory. The average Cobb angle of the lateral process was 4.2° (correction rate: 91.7%), with an excellent rate of screw placement (100%).ConclusionThis computer-assisted orthopedic surgery method has the potential to improve the safety and accuracy of surgical procedures for idiopathic scoliosis and reduce the operation time.
