概括
最佳的腰部侧侧体间融合 (LLIF) 高度与触觉反和测量压力有关. 120N的适当的提取力可以防止端板损坏,这种损坏在压力≥127N时会发生.
科学领域:
- 脊柱外科手术 脊柱外科手术
- 骨科生物力学 骨科生物力学
- 外科手术仪器仪表的使用.
背景情况:
- 外科医生在腰部侧侧体间融合 (LLIF) 取过程中依赖触觉反,但其与测量的手术内压力相关性尚不清楚.
- 了解这种关系对于优化子选择和预防手术并发症至关重要.
研究的目的:
- 测量在插入和提取过程中对LLIF子施加的压力.
- 为了将拉出强度的触觉反与测量的子压力相关联.
- 为了确定最佳的子高度,并识别端板损坏的风险.
主要方法:
- 一项涉及四具尸体和12个脊椎间空间 (L2/3到L4/5) 的尸体研究.
- 使用斜腰横向方法插入不钢压力测量 (8,10,12毫米).
- 测量椎间盘高度 (IDH) 和手术内压力.
- 由四名脊椎外科医生进行的提取强度的定性评估和对端板损伤 (ED) 和前纵带带损伤 (ALLI) 的评估.
主要成果:
- 子压力与触觉反有显著的相关性:45N (松散),120N (适当),191N (难以提取).
- 端板损伤 (ED) 发生在平均最大压力为127N时;没有观察到前沿带损伤 (ALLI).
- 对于ED的主要危险因素是插入子高度和本地IDH之间的差异>4.5毫米.
结论:
- 适当的子提取力相当于120N,表明最佳的适合性和稳定性.
- 子压力为127N或更高,增加了端板损坏的风险.
- 避免LLIF子和本地椎间盘高度之间的过度高度差异对于防止端板损伤至关重要.

Assessment of the Abdomen III: Palpation
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...
Assessment of the Abdomen II: Percussion
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.
