Objective: To evaluate the surgical safety and clinical efficacy of Subpedicle Subtraction Osteotomy (SPSO) for treatment of posttraumatic thoracolumbar kyphosis. Methods: A total of 43 patients diagnosed with posttraumatic thoracolumbar kyphosis were treated by SPSO. The mean follow-up period was 31.72 ± 6.43 months. Visual Analog Scale (VAS), Oswestry Disability Index (ODI) and general complications were recorded. The sagittal Cobb angle, Pelvic Incidence (PI), Pelvic Tilt (PT), Sacral Slope (SS) and Sagittal Vertical Axis (SVA) of the thoracolumbar kyphosis were measured to evaluate the sagittal balance preoperatively, 3 months postoperatively and the final follow-up. Results: The average surgical time was 176 ± 19.56 min (range from 148 to 219 min). The mean intraoperative blood loss of 624.52 ± 139.16 ml (range from 380 ml to 840 ml). The VAS score of back pain was 6.86 ± 1.57 before operation, which improved to 1.36 ± 0.55 at final follow-up, with a significantly improved (P<0.01). The mean ODI was 64.82 ± 4.73% preoperatively to 27.83 ± 1.49% at the final follow-up (P<0.01). Compared with preoperative, the Cobb angle, PT and SS at three months postoperative and last follow-up were corrected significantly (P<0.01). The SVA were improved from 10.86 ± 3.24 cm at preoperative to 3.86 ± 1.37 cm at final follow-up (P<0.01). Conclusion: It could be safely and efficacy of the treatment of posttraumatic thoracolumbar kyphosis with SPSO.
