概括
脚外的步态会增加骨骨关节的负荷和膝盖的硬. 这种步态修改虽然旨在减少膝盖的其他负荷,但会增加膝盖上的力量,这表明临床医生应该谨慎.
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 运动医学 运动医学
背景情况:
- 脚外行走是一种建议的保守治疗方法,以减少中间骨骨关节的压力.
- 脚外的步态对腿骨关节负荷的影响尚不清楚.
研究的目的:
- 为了研究脚外的步态修改对健康成年人腿骨关节负荷的影响.
主要方法:
- 十六名健康成年人接受了3D运动分析和力量板测量,这些测量是在自然和脚外的步态中进行的.
- 计算了膝盖曲角度,膝盖曲时刻和动态膝关节硬度.
- 使用肌肉骨模拟来确定峰值的骨骨压力.
主要成果:

Bones of the Lower Limb: Femur and Patella
2.6K
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...

Knee Joint
2.0K
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...

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...
