  • Effectiveness of trans-intervertebral space osteotomy combined with cage implantation for old thoracolumbar compression fracture with kyphosis

    Objective To investigate the effectiveness of trans-intervertebral space osteotomy (TIO) combined with cage implantation in treatment of old thoracolumbar compression fracture with kyphosis. Methods A clinical data of 59 patients with old thoracolumbar compression fracture and kyphosis, who met the selection criteria between January 2010 and August 2020, was retrospectively analyzed. Among them, 20 cases underwent TIO combined with cage implantation (group A), 21 patients underwent TIO (group B), and 18 patients underwent pedicle subtraction osteotomy (PSO; group C). There was no significant difference in gender, age, time from injury to operation, fracture segment, and preoperative Cobb angle, average height of functional spinal unit (FSU), sagittal vertical axis (SVA), visual analogue scale (VAS) score, Japanese Orthopedic Association (JOA) score, and Oswestry disability index (ODI) between groups (P>0.05). The operation time, intraoperative blood loss, and postoperative complications were recorded. Imaging review was performed to observe the fusion of the bone graft. Cobb angle, average height of FSU, and SVA were measured. VAS score, JOA score, and ODI were used to evaluate the degree of low back pain and lumbar function. Frankel grading was used to evaluate neurological function. Results The operations of 3 groups were successfully completed. The operation time and intraoperative blood loss were significantly lower in groups A and B than in group C (P<0.05); there was no significant difference between group A and group B (P>0.05). All incisions healed by first intention. Patients in all groups were followed up 23-27 months, with an average of 24.8 months. There was no significant difference in follow-up time between groups (P>0.05). At last follow-up, VAS score, JOA score, ODI, and SVA of 3 groups significantly improved when compared with those before operation (P<0.05), there was no significant difference in the differences of pre- and post-operation between groups (P>0.05). The neurological function grading of 3 groups was Frankel grade E. The Cobb angle and the average height of FSU in 3 groups at immediate and last follow-up significantly improved when compared with preoperative ones (P<0.05), there was no significant difference between immediately after operation and last follow-up (P>0.05). And there were significant differences in above indexes between groups at each time point (P<0.05). At last follow-up, the osteotomy site fused without internal fixation failure or pseudarthrosis formation were observed in 3 groups. ConclusionFor patients with old thoracolumbar compression fractures with kyphosis, the effectiveness of TIO combined with cage implantation is satisfactory. Compared with TIO and PSO, it can obtain more deformity correction degree and less invasive.

  • Effectiveness of limited middle and posterior column osteotomy via transvertebral space approach for old thoracolumbar compression fracture

    ObjectiveTo investigate the effectiveness of limited middle and posterior column osteotomy via transvertebral space approach in treatment of old thoracolumbar compression fracture.MethodsA 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.ResultsThe 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.ConclusionFor 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.
