概括
在部疼痛中常见的骨,不会显著影响脚下带 (plantar fascia).
科学领域:
- 生物力学 生物力学
- 整形外科 整形外科 整形外科
- 人体解剖学 解剖学 解剖学
背景情况:
- 卡尔卡纳斯棘越来越普遍,通常与脚跟和脚部疼痛有关.
- 它们在足部生物力学中的确切作用和对精力冲动力的贡献尚不清楚.
- 现有的假设将刺激形成与运动,长时间站立和肥胖有关.
研究的目的:
- 为了研究脚下神经结合带有和没有脚下刺的脱落性质.
- 为了确定马刺是否会影响足部带膜的中央带的拉出力.
主要方法:
- 分析了24个尸体的脚部,用X射线识别了骨.
- 脚下关节被切割并使用3D打印的紧固装置进行拉力测试.
- 测量了关键的突破参数,包括最大力 (Fmax) 和最大力 (εFmax) 的应变.
主要成果:
- 没有发现有和没有刺的脚之间的脱落特性具有统计学意义的差异.
- 刺激样本 (n=7) 的平均Fmax为1121 ± 358 N,而非刺激样本 (n=14) 的平均Fmax为953 ± 283 N.
- 刺激样本的平均eFmax为53±11%,非刺激样本为51±13%,可见高可变性.
结论:
- 脚部带中央带的拉出力与骨的存在没有显著的关系.
- 结果表明,形棘不太可能在足底带膜复合体内发挥生物机械功能.
- 需要进一步的研究来了解骨的临床意义和病因因素.

01:10Ankle Joint
2.7K
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...

01:28Muscles of the Leg that Move the Foot and Toes
3.9K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....
