概括
骨盆位置在站立和侧 (LD) 位置之间发生显著的变化,影响骨方向. 在LD中进行全关节整形术 (THA) 的外科医生必须考虑这些脊骨膜参数的变化,以实现最佳的植入物放置.
科学领域:
- 整形外科 整形外科 整形外科
- 放射学 放射学是一门学科.
- 生物机械工程 生物机械工程
背景情况:
- 在关节整形术 (THA) 中,脊椎骨盆参数 (SPPs) 对于骨杯的放置至关重要.
- 了解SPP的位置变化对于准确的手术规划和植入物定位至关重要.
- 侧面部 (LD) 位置经常用于THA,但其对SPPs的影响尚未完全表征.
研究的目的:
- 在站立,坐着和侧卧 (LD) 位置之间过渡时调查脊骨盆参数 (神经斜率,骨盆倾斜,前倾斜) 的变化.
- 为优化关节整形手术 (THA) 时,在LD位置进行关节整形手术时,提供关于优化关节杯位置的见解.
主要方法:
- 对140名接受初级THA.治疗的患者进行了回顾性研究.
- 在站立,坐着和LD姿势下获得了侧侧脊骨放射.
- 使用mediCAD®软件进行了十字斜率 (SS),骨盆倾斜 (PT),骨盆发生率 (PI) 和前倾斜 (AI) 的测量.
主要成果:
- 在三个位置 (P < 0.001) 中观察到SS,PT和AI的显著差异.
- 在从站立过渡到LD时,SS在51.4%的患者下降,而AI在47.9%增加.
- 在AI的变化与SS (P=0.02) 和PT (P=0.001) 有显著的相关性.
结论:
- 与站立相比,骨盆位置和骨方向在LD位置上可能会发生显著变化.
- 在站立状态下测量的脊椎皮质参数不能直接推断为LD位置.
- 对于THA外科医生来说,意识到这些手术内骨盆转移对于确保精确的植入物定位和潜在地改善术后结果至关重要.

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:19Abdominal Regions and Quadrants

To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...
