概括

这项研究量化了手臂下部曲率,发现飞行表面比背部更曲. 这些曲率半径 (ROC) 的差异为手骨生物力学和骨折固定技术提供了信息.

科学领域:

整形外科手术整形外科手术
人类解剖学人类解剖学
生物机械工程生物机械工程

背景情况:

甲手腕的形态,特别是它的曲率,还不太清楚.
了解曲率半径 (ROC) 对于评估手部生物力学,关节对齐和稳定性至关重要.

研究的目的:

为了量化背部和飞行曲率半径 (ROC) 的手臂下部.
测量甲手腕管道和地峡直径.
为了比较这些测量在五个手指甲骨.

主要方法:

使用了105张尸体手部的计算机断层扫描.
测量了所有手指甲骨的飞行和背部ROC,通道直径和地峡尺寸.
证实了高的interrater和intrarater可靠性 (ICCs> 0.95).

主要成果:

与背部ROC相比,所有手指甲骨都表现出较小,更曲的飞行ROC.
指甲手指有最大的ROC,而小指甲手指有最小的ROC.
大指的甲手腕表现出最大的内直径;第四个是最小的.

结论:

大指和小指的小飞行器ROC可能与抓取和对立功能有关.
背部表面相对直,具有较大的ROC.
外科医生可以使用背皮作为指导肌内固定;飞行ROC变化需要考虑骨折固定.

Muscles of the Forearm that Move the Hand and Fingers

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Bones of the Upper Limb: Radius

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...
