«Prof. Partridge in his lectures on anatomy at King's College was accustomed to compare the Ligamentum Teres, in its function, to the leathern straps by which the body of a carriage is suspended on springs » ( 1874SavoryWS ). Perhaps Nikolai Pirogov listened to these lectures ( 1859PirogoffN ). The analogy that Richard Partridge used could have arisen after reading the monograph Bell J. The Principles of Surgery (1801) . In it, the author depicted a cart and a pelvis resting on the head of one and two femurs. However, there is no mention of ligamentum capitis femoris (LCF) in the chart descriptions.

Prolygina KEYWORDS: ancient medicine; ancient traumatology; Galen; Hippocrates; hip joint; ligamentum capitis femoris; ligament of head of femur; ligamentum teres. SUMMARY Background. One of the least researched anatomical structures of the human body is the ligament of head of femur, most often referred to as ligamentum teres.
