Abstract:

BACKGROUND: For severe rigid kyphoscoliosis patients, due to severe spinal deformity, and high risk for orthopedic surgery, designing an individualized and precise placement and osteotomy scheme preoperatively is needed to reduce surgery risk.

OBJECTIVE: To evaluate the clinical effect of three-dimensional (3D) printing applied in the orthopedic surgery for severe rigid kyphoscoliosis.
METHODS: Thirty-two patients with severe rigid kyphoscoliosis from January 2015 to June 2017 were included. Sixteen cases underwent 3D-assisted osteotomy (preoperative spinal reconstruction by 3D printing, and designing rational osteotomy scheme, trial group), and other 16 cases received orthopedic surgery under X-ray (control group). The perioperative indexes, postoperative correction effect, accuracy of pedicle screw placement and incidence of complications were recorded.
RESULTS AND CONCLUSION: The operation time, intraoperative blood loss, intraoperative fluoroscopy time, postoperative drainage, postoperative incidence of complications, postoperative scoliosis and kyphosis Cobb angle in the trial group were significantly lower than those in the control group, but the accuracy of pedicle screw placement, scoliosis and kyphosis corrective rate were significantly higher than those in the control group (P < 0.05). To conclude, based on 3D printing, an individualized and precise placement and osteotomy scheme is designed for severe rigid kyphoscoliosis, can improve the operation safety, reduce the trauma, and obtain satisfactory clinical outcomes.
