Abstrakt:	Objective: To investigate the effectiveness of limited middle and posterior column osteotomy via transvertebral space approach in treatment of old thoracolumbar compression fracture. Methods: A clinical data of 47 patients with old thoracolumbar compression fractures, who met the selection criteria between January 2010 and March 2018, was retrospectively analyzed. Twenty-five patients (group A) underwent the limited middle and posterior column osteotomy via transvertebral space approach, and 22 patients (group B) underwent the pedicle subtraction osteotomy (PSO). There was no significant difference in gender, age, cause of injury, time from injury to operation, fracture segment, and preoperative Cobb angle, sagittal vertical axis (SVA), visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and Oswestry disability index (ODI) between the two groups ( P >0.05). The operation time, intraoperative blood loss, and postoperative complications, as well as postoperative Cobb angle, SVA, VAS score, JOA score, ODI and the differences of all indexes between pre- and post-operation were recorded and compared between the two groups. The neurological function was evaluated by Frankel scale. Results: The operations of both groups were successfully completed. The operation time and intraoperative blood loss in group A were significant lower than those in group B ( P <0.05). All incisions healed by first intetion. All patients were followed up 23-27 months (mean, 24.2 months) in group A and 24-28 months (mean, 24.8 months) in group B. At last follow-up, the VAS score, JOA score, ODI, Cobb angle, and SVA of the two groups were compared with those before operation, and the differences were significant ( P <0.05). There was no significant difference between the two groups ( P >0.05) in the indexes at last follow-up and the difference between pre- and post-operation. The lower extremity neurological symptoms (Frankel grade D) in 3 patients of group A before operation relieved (Frankel grade E) at last follow-up. The other patients were Frankel grade E. At last follow-up, CT showed bony fusion in the grafted area without any complications such as failure of internal fixation or pseudarthrosis. Conclusion: For patients with old thoracolumbar compression fractures, the limited middle and posterior column osteotomy via transvertebral space approach has a satisfactory effectiveness. Compared with PSO, it can reduce surgical trauma on the basis of achieving the same degree of deformity correction.
