1823GerdyPN

The author mentions their observation of the displacement of the femoral head from the acetabulum outwards when the ligamentum capitis femoris (LCF) is stretched. Continuing experimental research, P.N. Gerdy discovered that the LCF, when stretched during adduction, also displaces the femur in the caudal direction (see 1833GerdyPN).

PROPOSITIONS

La luxation du fémur en haut et en dehors est plus facile que celle en bas et en dedans, surtout parce que le ligament interarticulaire tend à s enrouler autour de la tête du femur, dans une violente adduction et qu il tire l os en dehors. Je m en suis assuré par l observation directe.

ASSUMPTIONS

Dislocating the femur upwards and outwards is easier than downwards and inwards, especially because the intra-articular ligament tends to spiral around the femoral head during strong adduction and pulls the bone outwards. I confirmed this through direct observation. [see: 1801BellJ !]

Fragment from the book Mondino de Luzzi, Dryander J. Anatomia Mundini (1541). An early description of the anatomy and role of the ligamentum capitis femoris (LCF) is presented. The pathogenesis of lameness and soft tissue atrophy in LCF pathology is discussed. For more details, see the commentary in 1541MondinoL_DryanderJ [Rus] . Quote p. 62.

Localization of LCF Pathology

Version : 20240418 Localization of LCF pathology is classified based on the anatomical-topographical principle. It is assumed that the LCF does not end near the attachment site but penetrates into it. LOCALIZATION OF LCF PATHOLOGY 1. Middle part 2. Distal end 3. Proximal end 4. Distal attachment area 5. Proximal attachment area 6. Medial surface 7. Lateral surface 8. Anterior edge 9. Posterior edge 10. Transsynovial 11. Subsynovial 12. Total Lesion The medial surface faces the bottom of the acetabulum. The lateral surface faces the femoral head. Transsynovial pathology implies changes including or only involving the synovial membrane. Subsynovial pathology is localized exclusively beneath the synovial membrane of LCF. Pathology can involve multiple parts of LCF, for example, damage to the distal end and proximal attachment area in a transacetabular fracture. The distal part of LCF attaches directly to the bone of fovea capitis femoris. Along...

Depicting the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not pre vail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.
