概括

较小的后动脉 (PTA) 和鼻动脉 (STA) 直径与较高的骨质突损伤发生率有关. 较大的OLT缺陷与较小的动脉直径相关.

科学领域:

整形外科整形外科整形外科
血管解剖学血管解剖学
放射学放射学是一门学科.

背景情况:

骨髓骨质中损伤 (OLT) 有多因素的原因,包括创伤,遗传和低血管性.
塔拉尔的血液供应主要来自后动脉 (PTA),次要来自鼻动脉 (STA).
低血管性在OLT发展中的具体作用尚不清楚.

研究的目的:

研究PTA (dPTA) 和STA (dSTA) 的直径与OLT的发生和特征之间的关系.
确定动脉直径缩小是否是OLT发展的危险因素.

主要方法:

这是一项回顾性研究,将77名患有OLT的患者与77名匹配的对照组 (年龄30-40岁) 进行了比较.
磁共振成像 (MRI) 用于测量dPTA在三个水平和dSTA在塔拉尔部.
记录的OLT特征包括面积,体积,深度,定位和需要手术干预的情况.

主要成果:

与对照组相比,OLT患者在所有测量水平上表现出明显较小的dPTA (P < .001).
在OLT组中,dSTA也明显较小 (P = .001).
平均dPTA切割值为1.1毫米预测了OLT的灵敏度为74%和特异性为75%,OLT大小与动脉直径相反相关 (P < .001).

结论:

缩小PTA和STA的直径与OLT的发病率增加有关.
骨质突缺陷的大小与这些动脉的直径具有反向相关性.

Ankle Joint

Ankle Joint

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...
