Abstract
We investigated the mechanism of Foucher's sign, the change in pressure in the Baker's cyst with extension and flexion of the knee, by echography, arthrography, and computed tomography. With extension the gastrocnemius and the semimembranosus muscles approximate each other and the joint capsule compressing the cyst against the deep fascia. Opposite effects in flexion allow the cyst to relax.
摘要
我们通过超声检查、关节造影和计算机断层扫描研究了福谢征（Foucher's sign）的机制，即随着膝关节屈伸，腘窝囊肿内压力的变化。膝关节伸直时，腓肠肌和半膜肌相互靠近，关节囊将囊肿压向深筋膜。膝关节屈曲时则产生相反的效果，使囊肿得以松弛。
