文题释义:
Viper脊柱微创系统:作为一套微创空心椎弓根固定系统,采用Ti6A14V钛合金材料,自身备有多种螺钉选择及棒的选择,具有直观、快速、肌肉创伤小的特点,由美国Depuy Spine Inc. 生产。
胸腰椎压缩性骨折:作为临床较为常见的脊柱骨折类型,往往出现因前屈应力造成椎体前柱压缩、后柱相对正常的改变,可伴有椎管内脊髓损伤等情况。对于此类疾病的治疗,早期多采用保守治疗,随诊解剖及生物力学的认识,当前多采用手术治疗。
 
摘要
背景:脊柱胸腰段作为应力的高度集中部位,往往容易出现椎体骨折。随着人们对脊柱生物力学及解剖结构知识的深入,脊柱后路切开复位椎弓根螺钉内固定已经获得临床医师的广泛接受。
目的:探讨Viper脊柱微创系统治疗胸腰椎压缩性骨折的临床疗效及安全性。
方法:收集2013年1月至2014年2月常州市中医医院骨科及解放军南京军区南京总医院收治胸腰椎压缩性骨折患者40例,根据患者植入物类型分为试验组(n=20)和对照组(n=20),分别采用Viper脊柱微创系统和单纯开放椎弓根螺钉内固定治疗。
结果与结论:两组患者病椎均获得骨性愈合;试验组在手术时间及骨愈合时间比对照组短,且术中出血量比对照组少。两组患者治疗前后Cobb’s角、前缘高度百分比和楔变角接近,但内固定后12个月时试验组患者伤椎前缘高度百分比较对照组低。2组患者内固定后目测类比评分和Oswestry功能障碍指数均较内固定前明显改善,但试验组患者内固定后即刻目测类比评分和Oswestry功能障碍指数比对照组低。结果说明,与单存开放椎弓根螺钉内固定相比,Viper脊柱微创系统治疗胸腰椎压缩性骨折由脊柱结构恢复稳定和功能恢复较好的特点且不增加围手术期并发症。

Abstract:

BACKGROUND: Thoracolumbar spine as highly concentrated stress, often prone to vertebral fractures. With the further development of the biomechanics and anatomical structure of the spine, posterior open reduction and internal fixation with pedicle screw has been widely accepted by clinicians.

OBJECTIVE: To explore the clinical results and safety of percutaneous pedicle screw fixation system (Viper system) used in thoracolumbar compression fractures.
METHODS: We retrospectively analyzed 40 patients with thoracolumbar compression fractures from Department of Orthopedics, Changzhou Traditional Chinese Medicine Hospital and Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA from January 2013 to February 2014. According to the type of graft, patients were randomly divided into experiment group and control group, with 20 patients in each group. They were respectively subjected to Viper percutaneous pedicle screw fixation system and open reduction and pedicle screw fixation.

RESULTS AND CONCLUSION: All vertebra got bone unions. Operative time and time to bone union were shorter in the experiment group than in the control group. Moreover, intraoperative blood loss was less in the experiment group than in the control group. Cobb’s angle, height percentage of leading edge and wedge angle were similar between the two groups. However, at 12 months after internal fixation, height percentage of leading edge was lower in the experiment group than in the control group. Visual Analogue Scale scores and Oswestry Disability Index were noticeably improved after fixation in both groups. Visual Analogue Scale scores and Oswestry Disability Index were lower in the experiment group than in the control group immediately after fixation. These results suggest that compared with open reduction and pedicle screw fixation, Viper percutaneous pedicle screw fixation system for thoracolumbar compression fractures can stably restore the structure and function of spine, and does not increase perioperative complications.
