概括
后腰椎间体融合 (PLIF) 在患有腰椎脊髓溶解症的患者中显著增加脊柱通道和持续囊的截面面积 (CSA). 这种手术减压提供了显著的形态改善,如MRI术后测量所证明的那样.
科学领域:
- 神经外科 神经外科
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
背景情况:
- 腰椎脊髓缩是一种退行性脊柱状况,通常需要手术干预.
- 带有仪器的后腰间体融合 (PLIF) 是腰部不稳定的标准治疗方法.
- 脊柱通道和持续囊的横截面积 (CSA) 是评估神经性损害的关键指标.
研究的目的:
- 在PLIF手术后评估脊柱通道和持续囊CSA的放射性变化.
- 建立客观的形态参数来评估外科手术的结果.
- 为了将PLIF与脊髓和长度囊尺寸的显著增加相关联.
主要方法:
- 74名接受PLIF的患者 (24名男性,50名女性;平均年龄66.49岁) 的回顾性分析.
- 获得了手术前和手术后 (1周内) 的T2加权轴向MRI扫描.
- 在L4-L5椎间盘水平上测量脊柱通道CSA和持续囊CSA.
主要成果:
- 脊柱通道的平均CSA从手术前的70.28mm2增加到手术后的149.59mm2.
- 平均持久囊CSA从手术前的42.46 mm2增加到手术后的98.93 mm2.
- 观察到显著的增加:脊柱通道CSA增加了112.84% (P < .001) 和持续囊CSA增加了132.99% (P < .001).
结论:
- PLIF手术导致脊柱通道和持续囊CSA的实质性和统计学上显著增加.
- 这些形态变化表明神经元件的有效解压.
- 医生应告知患者PLIF后显著的维度增加.

Vertebral Column: Regions and Curvature
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 the...

General Structure of a Vertebra
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.
