Abstract：Objective To study the clinical effect of transverse process on the crest of pedicle screw placement in the fracture of thoracic spine. Methods This study used the retrospective method. 73 patients with thoracic spine fracture atre admitted in the Department of Orthopedics from 2012 February to 2014 December. Their fracture treatment and follow-up data were analyzed, and according to the operation method were divided into the study group (39 cases, using the transverse process on the crest of pedicle screw implantation therapy) and control group (34 cases, using the traditional planting nail implantation therapy). The results of follow-up 12 months after operation in the two groups were comparatively analyzed. Results In study group, operative time (189.5±27.9) min, blood loss (420.4±61.5) ml were significantly lower than in control group (P＜0.05). In study group vertebral height immediately after surgery and last follow-up (36.1±1.5) mm, edge height of vertebral body (36.2±1.5) mm were significantly higher (P＜0.05). Cobb angle immediately after surgery in the study group (4.1±0.7)° was significantly less than in the control group (6.2±0.8)° Lost Cobb angle(P＜0.05). after termination of the follow-up in study group (2.3±0.5)° was significantly less than in the control group (3.9±0.8)°(P＜0.05). Postoperative complication rate in study group was 10.25%, lower than the 14.71% in the control group but the difference was not statistically significant. Conclusions Using the transverse process on the pedicle screw implantation in the treatment of thoracic vertebral fracture crest, compared with the traditional method of nail implantation, can significantly shorten operation time, reduce intraoperative hemorrhage, be conducive to postoperative patients recovery, and the curative effect is reliable.
