概括
骨关节炎 (OA) 显著改变了脚骨结构,增加了骨密度和厚度,同时减少了异型性. 个体椎细分显示了OA骨中更多的杆状和板状结构,特别是在表面附近.
科学领域:
- 整形外科和生物医学工程
- 骨生物学和疾病
背景情况:
- 晚期骨关节炎 (OA) 与子冠状腺骨微架构的显著变化有关.
- 脚关节这些骨变化的详细表征仍然未得到报道.
研究的目的:
- 与非患病 (ND) 对照组相比,全面描述OA关节骨样本中的带形态.
- 通过使用标准和个体状细分 (ITS) 分析,调查状骨微架构的深度依赖性变化.
主要方法:
- 微计算机断层扫描 (micro-CT) 扫描十个ND和五个OA脚骨样本.
- 使用BoneJ和3D ITS在1毫米深度增量时分析4毫米立方体体积.
- 测量形态参数,包括骨体积分数,状厚度和异质性.
主要成果:
- 与ND骨相比,OA骨表现出骨体积分数 (p<0.01) 和骨厚度 (p<0.001) 的增加,异质性降低 (p<0.05).
- ITS的分析显示,OA骨含有更多的杆状和板状骨干.
- 深度依赖性分析显示,杆状和板状轨道的厚度增加,杆子更长,底骨板附近的板面积增加.
结论:
- 这项研究证实了OA关节下丘脑骨中的显著微观结构变化,与其他下肢关节一致.
- 基于深度的分析为OA骨重塑机制提供了关键的见解.
- 了解底骨微型架构对于理解OA进展至关重要.

Ankle Joint
1.5K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Changes in the Appendicular Skeleton with Age

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...

Bones of the Lower Limb: Femur and Patella
2.4K
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...
