Ankle Joint01:10

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...

概括

下关节不稳定 (STJI) 可以通过侧侧脚带的角度来诊断. 与对照组相比,大多数STJI患者的ATFL-PTFL-CFL角度显著更高,这表明其具有诊断效用.

科学领域:

  • 整形外科的研究研究.
  • 医学成像分析分析 医学成像分析
  • 人体解剖学 解剖学 解剖学

背景情况:

  • 关节的稳定性依赖于侧侧带,包括前足带 (ATFL),足带 (CFL) 和后足带 (PTFL).
  • 有限的研究存在于患有下关节不稳定 (STJI) 患者的ATFL,CFL和PTFL角度的变化.

研究的目的:

  • 调查ATFL-CFL-PTFL角度和STJI之间的相关性.
  • 探索这些角度作为有效的STJI评估的新指标的潜力.

主要方法:

  • 采用了一个追溯案例系列设计.
  • 磁共振成像 (MRI) 用于比较110名STJI患者和110名对照者的关节带角度.
  • 在STJI和对照组之间测量和比较了ATFL-CFL-PTFL角度.

主要成果:

  • 在STJI和对照组之间观察到ATFL-PTFL,ATFL-CFL和PTFL-CFL角度的显著差异 (p <0.01).
  • 在STJI组中,平均角度较高:ATFL-PTFL (86.3° ± 3.6°),ATFL-CFL (131.4° ± 4.7°) 和PTFL-CFL (96.5° ± 4.0°).
  • 对照组显示较低的平均角度:ATFL-PTFL (79.5°±3.8°),ATFL-CFL (126.8°±3.5°) 和PTFL-CFL (86.3°±2.9°).对照组显示较低的平均角度:ATFL-PTFL (79.5°±3.8°),ATFL-CFL (126.8°±3.5°) 和PTFL-CFL (86.3°±2.9°).

结论:

  • 虽然ATFL-PTFL-CFL角分布显示STJI和对照组之间的重叠,但STJI患者的价值较高.
  • 这些带角度显示希望作为二级诊断指数,用于识别下关节不稳定.
