旋前方肌在解剖学和功能学文献中很大程度上被忽视。本研究证实了肌肉中两个不同头部的一致存在，并定义了大体和显微解剖结构。这些头的功能意义已经研究了使用在体外和体内的技术，以证明，浅头是前臂旋前的原动力，而深头是一个动态稳定的远端桡尺关节。
The pronator quadratus muscle has been neglected to a great extent in the anatomical and functional literature. This study confirms the consistent presence of two distinct heads to the muscle, and defines the gross and microscopic anatomy. The functional significance of these heads has been studied using in vitro and in vivo techniques to demonstrate that the superficial head is the prime mover in forearm pronation, and that the deep head is a dynamic stabilizer of the distal radioulnar joint.
