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.
