PURPOSE: The aim of this review is to systematically screen the literature for clinical and biomechanical studies dealing with posterior stabilization of acute traumatic mid-thoracic vertebral fractures in patients with normal bone quality. METHODS: This review is based on articles retrieved by a systematic search in the PubMed and Web of Science database for publications up to December 2018 dealing with the posterior stabilization of fractures of the mid-thoracic spine. RESULTS: Altogether, 1012 articles were retrieved from the literature search. A total of 960 articles were excluded. A total of 16 articles were dealing with the timing of surgery in polytraumatized patients, patients suffering of neurologic deficits after midthoracic fractures, and the impact of concomitant thoracic injuries and were excluded. Thus, 36 remaining original articles were included in this systematic review depicting the topics biomechanics, screw insertion, and outcome after posterior stabilization. The overall level of evidence of the vast majority of studies is low. CONCLUSION: High quality studies are lacking. Long-segmental stabilization is indicated in unstable midthoracic fractures with concomitant sternal fractures. Generally, long-segmental constructs seem to be the safer treatment strategy considering the relative high penetration rate of pedicle screws in this region. Thereby, navigated insertion techniques and intraoperative 3D-imaging help to improve pedicle screw placement accuracy.
目的:本综述的目的是系统地筛选文献,寻找关于正常骨质量患者急性创伤性胸中段脊柱骨折的后向稳定的临床和生物力学研究。
方法:本综述基于在 PubMed 和 Web of Science 数据库中进行的系统搜索,检索截至 2018 年 12 月的关于胸中段脊柱骨折后向稳定的文献。
结果:共从文献检索中检索到 1012 篇文章。共有 960 篇文章被排除。共有 16 篇文章涉及多发伤患者的手术时机、胸中段骨折后神经功能缺损患者以及合并性胸伤的影响,这些文章被排除在外。因此,36 篇剩余的原始文章被纳入本系统综述,内容涉及生物力学、螺钉插入和后路稳定后的结果。大多数研究的总体证据水平较低。
结论:高质量的研究缺乏。不稳定的胸中段骨折伴胸骨骨折需行长节段稳定。一般来说,考虑到该区域椎弓根螺钉的相对高穿透率,长节段结构似乎是更安全的治疗策略。因此,导航插入技术和术中 3D 成像有助于提高椎弓根螺钉放置的准确性。
