概括
M6-CTM椎全盘置换 (CTDR) 显示骨解 (44%) 和异型骨化 (34%) 的高率,在12%的患者中植入物失败. 建议进行持续监测,特别是在C5/6.6的男性身上.
科学领域:
- 脊柱外科手术 脊柱外科手术
- 整形外科的植入物.
- 生物材料是一种生物材料.
背景情况:
- 之前的一项研究报告说,由于与磨损相关的骨质溶解,M6-CTM椎全盘置换 (CTDR) 的修订率为34%.
- 本研究调查了与M6-CTM人造磁盘相关的周围假肢骨变化和植入失败的流行率,风险因素和放射性特征.
研究的目的:
- 为了确定在M6-CTM CTDR后周围假肢骨变化和植入物失败的发生率.
- 确定与这些并发症相关的风险因素和放射特征.
- 将发现与之前关于M6-CTM植入物结果的报告进行比较.
主要方法:
- 从2011-2015年间接受M6-CTM CTDR的患者的放射 (X射线,CT) 和临床数据 (EQ-5D-5L,NDI,VAS) 的回顾性分析.
- 在43名患者中对50个植入物的评估,平均随访时间为8.1年.
主要成果:
- 由于严重的骨质溶解而导致的植入失败发生在5名患者 (12%),所有男性和植入C5/6,需要修复手术.
- 整体骨质溶解的发生率为44% (22/50植入物),异型骨化为34% (17/50植入物).
- 高度骨解与增加的VAS手臂疼痛和较低的EQ-5D-VAS分数相关.
结论:
- 在这个队列中,M6-CTM植入物的重新操作率低于之前报告的水平.
- 在M6-CTM CTDR后,骨解和异型骨化是常见的,并且可能无症状.
- 建议在M6-CTM CTDR后继续进行临床和放射性监测,特别是在C5/6水平的男性患者中.

Herniated Intervertebral Disc l: Introduction
44
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Degenerative Disc Disease I: Introduction
29
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology
34
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
