概括

膝盖扭曲是形形和反复发生的脱位的关键指标. 7°和12°的值可以预测J符号等级,有助于对骨不稳定的手术决定.

科学领域:

整形外科手术整形外科手术
生物机械工程生物机械工程
放射学放射学是一门学科.

背景情况:

经常出现的带脱位通常与潜在的骨异常有关.
评估膝关节的对齐和扭动对于理解形关节的不稳定性至关重要.
"J"标志是形形的临床指标,但其与特定扭矩值的相关性需要进一步阐明.

研究的目的:

在健康个体中确定膝盖扭曲的规范值.
确定膝盖扭曲的预测值,以不同级别的J标志在患有复发型带脱的患者.
为了研究膝盖扭曲和带不良跟踪的严重程度之间的关系.

主要方法:

这是一项前性研究,涉及健康的志愿者和患有复发性带脱的患者.
膝盖扭曲和骨异常被评估使用关节膝关节关节CT扫描.
基于视觉检查皮带错误跟踪,进行了J标志分级,并进行了统计分析,包括ROC曲线以确定预测值.

主要成果:

在健康的膝盖和不同的J标志等级 (p < 0.001) 中观察到平均膝盖扭曲的显著差异.
确定了J标志等级的值:< 5.5°对于健康/J标志1+,7.2°8.1°对于J标志2+,和10.2°12.8°对于J标志3+.
每增加1°的扭矩都会使J标志等级更高的概率增加25.4% (或1.254),ROC分析显示了在5.5°,7°和12°的优异差异.

结论:

膝关节扭转值为5°6°,与带不良追踪有关.
膝盖扭曲显著预测J标志的严重程度,每~4度扭曲增加1度.
术前值为7°和12°的J标志等级,需要进行常规CT扫描,以便在复发的骨脱中进行手术规划.

Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Bones of the Lower Limb: Femur and Patella

Bones of the Lower Limb: Femur and Patella

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...

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...
