Abstract：Objective To explore the effect of modified posterior unilateral vertebral column resection(PUVCR) through unilateral approach for the treatment of thoracolumbar kyphosis caused by wedged vertebrae.Methods From Jan. 2010 to May 2013, 29 cases of spinal kyphosis caused by wedged vertebrae were treated in the third hospital of Hebei Medical University and enrolled in this study, 14 patients received PUVCR as experimental group with six males and eight females, the average age was(26.7±4.7)years (17-33 years), the preoperative kyphotic angle was 62.3°±7.6°. Fifteen patients received posterior vertebral column resection (PVCR) as control group with seven males and eight females, the average age was (24.3±3.8) years (18-32 years), the preoperative kyphotic angle was 58.3°±8.7°. The clinical records were reviewed and compared for operating time, operative and postoperative blood loss, correction of kyphotic deformity, functional improvement (Oswestry disability index, ODI), pain (visual analog scale, VAS) and complications.Results The two groups were compatible in age, sex composition and preoperative kyphotic(all P values＞0.05). There was no difference between PVCR and PUVCR groups in terms of correction of kyphotic angle two weeks postoperatively, loss of correction in one-year follow up, improvement of ODI and decrease of VAS in one-year follow up(all P values＞0.05). The operating time in PUVCR group was shorter than that in PVCR group. The blood loss and postoperative loss in PUVCR group was less than that in PVCR group(all P values＜0.05). The rate of intraoperative unintentional impingement was 13.3%(2/15) in PVCR group and 7.1%(1/14)in PUVCR group. All patients achieved bony fusion in one-year follow up.Conclusions Satisfactory correction of sagittal deformity, functional improvement and pain relief can be achieved with PUVCR, Which can shorten the operating time, lessen blood loss and lower rates of nerve root impingement compared to PVCR.
