概括
下关节偏移 (SJO) 是一种可靠的负重计算断层扫描 (WBCT) 测量方法,用于评估下关节对齐. 这种新的度量有助于区分,中性和 varus 后脚对齐 (HA).
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.
- 生物力学 生物力学
背景情况:
- 脚和脚偏移 (FAO) 是一个3D WBCT测量后脚对齐 (HA).
- 粮农组织提供了一个整体的观点,但并没有孤立下关节 (SJ) 的对齐.
- 介绍SJO作为SJ对齐的新型3DWBCT度量.
研究的目的:
- 引入和评估SJO作为3DWBCT测量的可靠性.
- 为了评估SJO在中性,和的后脚对齐 (HA) 中区分分别的潜对齐的能力.
- 为了将SJO与脚和脚偏移 (FAO) 测量进行比较.
主要方法:
- 对于204英尺的回顾性研究,粮农组织将其分类为中性,状或状.
- 使用WBCT软件计算SJO,通过识别相对于脚三脚架的SJ骨中侧面位置.
- 通过使用类内相关系数 (ICC) 评估观察者内部和观察者间的可靠性.
主要成果:
- 对于SJO (分别为0.98和0.92),观察者内部和观察者间的ICC非常出色.
- 在中性,瓦尔古斯和瓦鲁斯群体中,粮农组织和SJO的显著差异 (P < .001).
- 粮农组织和SJO之间的相关性在瓦鲁斯和瓦尔古斯组中适度,在中性组中低.
结论:
- SJO是一种可靠的WBCT指标,用于区分各种后脚对齐 (HA) 中的亚位对齐.
- SJO-FAO的差异可以量化亚对整体HA的贡献.
- 需要进一步的前性多中心研究来验证SJO在手术规划中的临床实用性.

Ankle Joint
2.8K
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...

Bones of the Lower Limb: Tibia and Fibula
8.8K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
