概括
超声波可以评估慢性脚不稳定性 (CAI) 中的下关节不稳定性. 在CAI患者中,较大的下关节外流 (STJE) 表明不稳定性,与主观不稳定性得分相关.
科学领域:
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
- 诊断成像 诊断成像 诊断成像
背景情况:
- 慢性脚不稳定性 (CAI) 通常涉及亚关节功能障碍.
- 目前对下关节不稳定的评估方法可能是主观的.
- 超声波为联合评估提供了一个潜在的客观措施.
研究的目的:
- 开发和验证超声波,以评估CAI患者的下关节不稳定性.
- 为了将超声波测量与脚不稳定的主观测量相关联.
主要方法:
- 46名CAI患者和26名对照患者进行了超声波评估.
- 在休息状态和最大反转过程中测量了下关节外流 (STJE).
- 在使用ANOVA的CAI,无症状和对照组之间进行了STJE比较.
- 斯皮尔曼相关性评估了STJE和主观不稳定性得分 (CAIT,AIIT) 之间的关系.
主要成果:
- 与无症状 (1.0 mm) 和对照 (0.8 mm) 组相比,在CAI组 (2.3 mm) 中STJE显著增加 (p < 0.001).
- STJE与CAIT (r = -0.71) 呈现强烈的负相关性,与AIIT (r = 0.74) 呈现正相关性.
- 截止STJE值为1.7毫米,通过ROC分析有效区分CAI与无症状组.
结论:
- 超声波提供了一种可靠的方法,以评估CAI的下关节不稳定性.
- 通过超声波测量STJE的增加是CAI的重要指标.
- 这种成像技术可以客观地区分不稳定和稳定的脚.

Ankle Joint
1.6K
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...

Ultrasonography
4.6K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
