Anatomical Positions

10.3K
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...

Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

2.6K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Changes in the Appendicular Skeleton with Age

2.1K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

科学领域:

  • 整形外科 整形外科 整形外科
  • 生物力学 生物力学
  • 脊柱外科手术 脊柱外科手术

背景情况:

  • 成年脊柱形 (ASD) 与盆腔逆转有关.
  • 盆腔逆转可能会增加部负荷,导致部脊柱综合征.

研究的目的:

  • 为了研究骨盆逆转如何在走路时改变ASD患者的骨方向.
  • 为了探索动态的acetabular方向和关节骨关节炎在ASD之间的关系.

主要方法:

  • 89名自闭症患者和37名对照人接受了3D步态分析和全身双平面X射线.
  • 在行走过程中计算出静态和动态的脊椎骨盆和骨参数.
  • 根据高的骨盆倾斜 (PT) 进行对比,将ASD患者分组为组.

主要成果:

  • 患有高PT的ASD患者表现出明显更严重的姿势不对齐.
  • 高PT组在步行过程中表现出更大的动态骨盆逆转.
  • 在走路期间,在ASD-高PT中观察到增加的acetabular anteversion,外部覆盖和前部覆盖的减少.

结论:

  • 在ASD中严重的骨盆逆转会改变步行过程中动态的acetabular方向.
  • 这些与步态相关的acetabular变化与ASD患者的关节骨关节炎有关.
