Each year, there are approximately 5 million new vertebral fractures worldwide. Being a mobile flexible segment that is prone to severe stresses and loads, thoracolumbar fractures are considered one of the most controversial and challenging fracture types to manage. The aim of this study is to explore the technique and to evaluate feasibility, safety, and outcome of percutaneous transpedicular fixation in the management of thoracolumbar fractures. This study was carried out in the period between May 2016 and June 2017, where 20 consecutive patients with thoracolumbar fractures, based on TLICS scoring and neurological status, underwent a posterior percutaneous transpedicular fixation. The mean age was 33.85 years, range 20–49 years. Patients were followed up for 12 months. Patients had their clinical outcomes reviewed and evaluated in terms of cosmesis by visual analog scale (VAS) and in terms of Cobb angle correction. The length of the procedure varied from 120 to 180 min with mean time of 154.50 min. There was no significant blood loss in all cases. The volume of blood loss ranged from 150 to 200 cc with mean loss of 174.25 cc. No major intraoperative complications happened in our study cases. Six cases had only one laterally malpositioned screw each. All cases returned to their previous activity without limitations (E5). Those who were completely pain free (F5) were 15 patients. Only five patients were suffering from moderate pain (F4). The Prolo scale was either 9 or 10 with mean of 9.60. By comparing our results with other studies, we found more or less equivalence in terms of neurological recovery, functional outcome, fusion rate, and maintenance of correction gain. However, the cosmesis scores for patients in the study were great.

微创经皮固定在胸腰椎骨折中的作用：一项前瞻性研究

每年，全世界大约有500万新的椎骨骨折。胸腰椎骨折是易受严重压力和负荷的活动性柔性节段，被认为是最有争议和最具挑战性的骨折类型之一。这项研究的目的是探索技术，并评估经胸椎椎弓根内固定治疗胸腰椎骨折的可行性，安全性和结果。这项研究于2016年5月至2017年6月进行，根据TLICS评分和神经系统状况，连续20例胸腰椎骨折患者接受了后经皮椎弓根固定。平均年龄为33.85岁，范围为20-49岁。对患者进行了12个月的随访。根据视觉模拟量表（VAS）的美容效果和Cobb角矫正对患者的临床结局进行了评估。该过程的时间从120到180分钟不等，平均时间为154.50分钟。所有病例均无明显失血。失血量在150至200 cc之间，平均失血量为174.25 cc。在我们的研究病例中，没有发生重大的术中并发症。六个病例每个仅含一个错位的螺钉。所有案例均不受限制地返回到其先前的活动（E5）。那些完全没有疼痛（F5）的患者为15例。仅五名患者患有中度疼痛（F4）。Prolo量表为9或10，平均值为9.60。通过将我们的研究结果与其他研究进行比较，我们发现神经功能恢复的等效性，功能结果，融合率和校正增益的维持。但是，研究中患者的美容评分很高。
