概括
腰部融合手术后面内真空现象 (VP) 的变化表明机械并发症的风险更高,功能结果更差. 然而,内VP变化与这些结果没有显著的相关性.
科学领域:
- 脊柱外科手术 脊柱外科手术
- 放射学 放射学是指放射学
- 生物机械工程 生物机械工程
背景情况:
- 真空现象 (VP) 是脊髓成像中的一个公认的放射学标志.
- 它的临床意义,特别是对于腰部融合后的术后结果,需要进一步阐明.
- 传统观点将VP与细分不稳定性联系在一起,但其对融合成功的预测价值仍在争论中.
研究的目的:
- 为了研究内部和内部真空现象 (VP) 的动态变化对腰椎融合后的临床和机械结果的影响.
- 确定手术后VP进化是否是并发症和功能恢复的预测因素.
- 在融合的背景下重新评估VP作为脊柱不稳定性指标的作用.
主要方法:
- 对于患有退行性脊髓疾病的腰部融合患者进行了回顾性队列研究.
- 对手术前和最后的后续腰部CT扫描进行分析,以评估内和面内VP的存在/不存在.
- VP动态与机械并发症 (相邻细分病,伪关节炎) 和患者报告的功能结果 (奥斯韦斯特里残疾指数) 的相关性.
主要成果:
- 新发病或已消失的面内VP与增加的机械故障 (73.3%) 和相邻细分疾病 (53.3%) 有显著的相关性.
- 静脉内VP变化与机械并发症没有显著的关联.
- 新开发的面内VP与较差的功能结果有关 (奥斯韦斯特里残疾指数). 身体间融合与VP变化和功能结果比后侧融合更相关.
结论:
- 术后的面内VP的变化,而不仅仅是它的存在,更多地表明腰部融合后的机械并发症和功能衰退.
- 这些发现挑战了传统的观点,认为内性VP是主要的不稳定性标志物.
- 身体间融合可能与改善的结果有关,这表明手术前规划和患者咨询的潜在好处.

01:16Vertebral Column: Regions and Curvature
4.1K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

2.7K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
