椎弓根置钉固定联合填充材料修复腰椎骨折

背景：传统的跨节段椎弓根螺钉内固定会引发后凸畸形和丢失矫正角度等并发症，而伤椎椎弓根置钉固定改善了传统后路置钉技术的不足，联合填充材料治疗腰椎骨折取得较为理想的恢复效果。 目的：探讨椎弓根置钉联合填充材料在腰椎骨折治疗中的临床应用价值。 方法：回顾性分析椎弓根置钉联合填充材料修复腰椎骨折患者的临床资料，分别实施椎弓根置钉联合植骨/骨水泥进行修复。观察患者术后伤椎椎体前后缘高度比值及后凸Cobb角变化情况，并进行随访比较。 结果与结论：椎弓根置钉联合填充材料具有很多优点，在治疗腰椎骨折上取得了不错的效果，但随着更广泛的应用也呈现出一些问题及争论，临床医生应更加重视手术适应证的选择、围手术期和远期并发症的防治，以及术后骨质疏松症的治疗。伤椎椎弓根置钉固定技术联合磷酸钙骨水泥有广阔的应用前景，能够维护脊柱复位效果，值得在腰椎骨折的临床治疗中大力推广。中国组织工程研究杂志出版内容重点：人工关节；骨植入物；脊柱；骨折；内固定；数字化骨科；组织工程 

Pedicle screw placement combined with filler for lumbar vertebra fractures

BACKGROUND:Conventional cross-segment pedicle screw fixation will cause some complications such as kyphosis and loss of corrective angle. Fixation of pedicle screw placement of the injured vertebral body improves the disadvantages of conventional posterior screw placement, and obtains ideal outcomes. OBJECTIVE:To investigate the clinical application value of pedicle screw placement combined with filler for lumbar vertebra fracture. METHODS:Clinical data of patients with pedicle screw placement combined with filler for lumbar vertebra fracture were retrospectively analyzed. They were repaired with pedicle screw placement combined with bone graft as well as pedicle screw placement combined with bone cement. The ratio of anterior border to posterior border of the injured vertebral body after surgery and changes in Cobb angle were observed. Patients were followed up and results were compared. RESULTS AND CONCLUSION:Pedicle screw placement combined with filler has many advantages, and obtained good outcomes in the treatment of lumbar vertebral fracture. However, the extensive application has some problems and disputes. Clinical physicians should pay more attention on choice of surgical indications, prevention and treatment of perioperative and long-term complications and postoperative treatment of osteoporosis. The pedicle screw fixation combined with calcium phosphate bone cement has a broad prospect, can maintain the effect of spine reduction, and is worth to spread in the clinical treatment of lumbar fractures.
