摘要

背景先前的研究报告称，患有骨质疏松性胸腰椎骨折（OVF）并伴有延迟性神经功能缺损的患者的手术通常具有侵袭性，并且由于涉及老年患者，因此会增加围手术期并发症和仪器故障。病例介绍本报告描述了一名70岁女性患有神经系统缺陷的OVF的动态稳定。影像学显示L3骨折，椎管狭窄伴L3-L4椎间盘突出。我们使用cosmicMIA对后部短节段进行了后部动态稳定™ 系统和减压。术后腰痛和腿痛减轻，术后影像学显示L2–L3小关节和L3–L4椎间体骨融合。结论我们的报告对使用cosmicMIA系统进行短节段后固定减压手术治疗老年OVFs具有指导意义。

A novel pedicle screw system for dynamic stabilization of osteoporotic vertebral fractures: A case report

Background

Previous research has reported that surgery for patients suffering from osteoporotic thoracolumbar vertebral fractures (OVFs) with delayed neurological deficits is often invasive and associated with increased perioperative complications and instrumental failure because they involve elderly patients.

Case presentation

This report describes the dynamic stabilization of an OVF with neurological deficits in a 70-year-old woman. Imaging showed a fracture of L3 and spinal canal stenosis with disc herniation at L3-L4. We performed a posterior dynamic stabilization with a posterior short segment using the cosmicMIA™ system and decompression. Low back and leg pain decreased after surgery, and postoperative imaging showed bone fusion of the L2–L3 facet joint and L3–L4 intervertebral body.

Conclusions

Our report is instructive for short-segment posterior fixation and decompression surgery using the cosmicMIA system to treat OVFs in elderly patients.
