Retrospective cohort.
The aim of this study is to evaluate the effectiveness of percutaneous short fixation (PSFx) plus kyphoplasty (BP) for thoracolumbar fractures.
Thirty-six consecutive selected patients, aged 59 ± 17 years, with fresh single thoracolumbar A, A, and B AO-type fracture, received PSFx plus BP. The primary outcomes pain, and vertebral body deformity; and the secondary outcomes screw malposition, facet violation, PMMA leakage, adjacent segment degeneration (ASD) and loss of correction were evaluated. The f/up was 31 ± 7 months.
Pain and kyphosis decreased and vertebral body heights increased significantly postoperation. PMMA leakage occurred in five cases; 6 (4 %) screws were grades III malpositioned in relation to pedicle; facet violation occurred in 8 (5.5 %) facets; loss of kyphosis correction was 3.68°; ASD occurred in two cases; interfacet fusion in ten (28 %) patients; Three patients were reoperated for different reasons.
PSFx plus BP for thoracolumbar fractures reduces significantly spinal deformity and pain with few complications.
回顾性队列研究。
本研究旨在评估经皮短节段固定（PSFx）联合椎体后凸成形术（BP）治疗胸腰椎骨折的有效性。
连续选取36例年龄为59±17岁的新鲜单节段胸腰椎AO A、A和B型骨折患者，接受PSFx联合BP治疗。评估主要结局指标疼痛和椎体畸形，以及次要结局指标螺钉位置不当、关节突侵犯、骨水泥渗漏、邻近节段退变（ASD）和矫正丢失情况。随访时间为31±7个月。
术后疼痛和后凸畸形减轻，椎体高度显著增加。发生5例骨水泥渗漏；6枚（4%）螺钉相对于椎弓根位置为III级不当；8个（5.5%）关节突发生关节突侵犯；后凸畸形矫正丢失3.68°；发生2例ASD；10例（28%）患者关节突间融合；3例患者因不同原因再次手术。
PSFx联合BP治疗胸腰椎骨折可显著减轻脊柱畸形和疼痛，并发症较少。
