概括

某些部定位系统和较高的患者在全关节整形术期间增加了部部件位的风险. 适当的骨盆方向对于最佳的骨绑架结果至关重要.

科学领域:

整形外科手术整形外科手术
放射学放射学是一门学科.
生物医学工程生物医学工程

背景情况:

在关节整体整形术 (THA) 中,关节部分的错位是一个重大问题.
实现正确的手术内骨盆方向 (PPO) 对于准确的部件放置至关重要.
侧面腰位置在保持骨盆对齐方面提出了独特的挑战.

研究的目的:

为了确定与增加的风险相关的因素,在THA.期间,在侧面位中出现形部件错位的风险.
为了评估手术内骨盆定向对骨绑架的影响.
为了比较不同部定位系统在实现PPO方面的有效性.

主要方法:

从后部THA手术中进行的813张X射线的回顾性审查.
在手术前和手术内X射线上测量骨盆倾斜和旋转.
在术后的X射线上评估骨绑架.

主要成果:

在69%的病例中,正确的手术内骨盆方向 (PPO) 得到了实现.
更矮的患者更有可能达到PPO (1.68m vs 1.72m).
与De Mayo定位器 (60%) 相比,Capello或Wixson部定位器导致更高的PPO率 (76%).
PPO与更高的实现目标acetabular绑架率 (88%与80%相比) 相关.

结论:

使用特定的部定位系统和患者身高是影响THA期间骨盆错位的重要因素.
骨盆位置不当会对骨部件的移除产生负面影响.
优化手术期间的骨盆方向对于成功的THA结果至关重要.

Anatomical Positions

Anatomical Positions

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...

Abdominal Regions and Quadrants

Abdominal 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...
