«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.

Fragment from the book Platter F. Observationum (1614). The author notes the role of the ligamentum capitis femoris (LCF) in fixing the femur in the acetabulum and the possibility of its lengthening (synovitis) . Quote pp. 141-142 [Lat] Cruris dextri astrictio & contractio, post coxendicum dolorem. Cùm enim ligamentum illud articulum circumd ás, omnium totius corporis ligamentorum, quae articulos ambiunt, sit amplissimum; fieri potest, ut adeò cedat, ut (sicuti saepe sit) femoris caput, è suo sinu devoluatur, & in membranae illius (quae cùm erassissima sit, prae omnibus totius corporis ligamentis, nunquam vi qualicunque disrumpi potest) amplitudine seu capacitate subsistat, elongato simul & vehementer attracto, tereti illo & crasso, quod caput aliàs in suo sinu retinere solet, ligamento.
