1833GerdyPN

P.N. Gerdy, in his experiment, discovered tensioning of the ligamentum capitis femoris (LCF) during thigh adduction. At the same time, it was noted for the first time that the consequence of LCF tension during hip adduction is a downward and lateral displacement of the femoral head. Normally, this mechanism provides unloading of the upper articular surfaces when supporting one leg (see 1874SavoryWS ). The translation from French was done in collaboration with ChatGPT 3.5. Gerdy PN. Physiologie médicale, didactique et critique. T. 1. Paris: Librairie de Crochard, 1833. [fragment] Quote pp. 551-554 L'inclinaison de la cuisse en dehors, que l'on nomme son abduction, est un mouvement assez étendu, mais qui pourtant ne permet pas à la cuisse de se placer perpendiculairement à sa direction verticale. Les batteleurs peuvent se reposer sur un plan horizontal, les cuisses écartées en sens opposé. Dans l'inclinaison ...
