概括
延伸器幻觉长 (EHL) 肌可靠地表明阿卡吉在全膝关节整形术 (TKA) 中为部件对齐的线. 这提供了一个实用的外关节里程碑,当在手术期间内关节引用被掩盖时.
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:
- 部部件的精确旋转对齐对于成功的全膝关节整形术 (TKA) 是至关重要的.
- 阿卡吉的线是公认的前后线参考,但如果后十字带 (PCL) 在切割后看不到,其在手术内使用是有限的.
- 延伸器长 (EHL) 肌提供了一个一致的,外关节的标志,用于骨对齐.
研究的目的:
- 用计算机断层扫描 (CT) 来评估Akagi的线和EHL肌之间的解剖关系.
- 分析这种关系与TKA规划的部形态参数之间的关联.
主要方法:
- 一项描述性相关性研究分析了100个正常骨的CT扫描.
- 阿卡吉的直线 (PCL中心到状肌中枢边界) 的远距离投影与EHL肌中心进行了比较.
- 测量了骨的长度,形态,后部斜率,斜距离,以及阿卡吉与大腿横轴 (TEA) 的直角.
主要成果:
- 阿卡吉线在60%的病例中穿过EHL肌中心,在40%的病例中穿过肌中心,没有横向偏差.
- 阿卡吉-EHL距离与骨长度 (ρ = 0.71) 和骨距离 (ρ = 0.70) 有着强烈的相关性.
- 在Akagi-femoralTEA角度和骨形态参数之间没有发现显著的关联.
结论:
- 阿卡吉线的远距离投射始终与EHL肌中心对齐或略微中间.
- 在TKA中,EHL作为可靠的,关节外远距离地标,用于骨旋转对齐,特别是当关节内参考被掩盖时.
- 这种可预测的关系有助于在全膝关节整形术期间精确地放置组件.

Muscles of the Leg that Move the Foot and Toes
4.5K
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....
