Ossification of the LCF

Illustration:

Left: X-ray of the hip joint (1); our designations: brown arrow – ossification of ligamentum capitis femoris (LCF); yellow arrow – thin articular cartilage in the lower sector of the femoral head and acetabulum; lig.IF – ligamentum iliofemorale; lig.teres – LCF.

In the center: cross-section of the hip joint (2); our designations: black arrow – the space of the acetabulum notch, and the thin layer of cartilage of the head of the femur; lig.IF – ligamentum iliofemorale; lig.teres – LCF.

Right: MRI of the hip joint (2); our designations: white arrow – the space of the acetabulum notch, and the thin layer of cartilage of the head of the femur; lig.IF – ligamentum iliofemorale; lig.teres – LCF.

A comment:

There is a thin layer of cartilage of the femoral head and acetabulum in the lower hemisphere of the hip joint. In our opinion, this is a consequence of the greater force of pressing the articular surfaces against each other. Ossification of part of the LCF is an extremely rare occurrence and indirectly indicates its damage. The rigid, continuous LCF cannot move with the head of the femur.

Eryops megacephalus

ERYOPS MEGACEPHALUS Eryops megacephalus Cope 1877 is an early tetrapod from the Permian (298 .9-251.9 Ma ), apparently showing strong similarities to salamanders (2022HerbstEC_HutchinsonJR; 2023CohenKM_C arN). Adults reached an advanced degree of terrestrial habitation and a size of about three meters from head to tail (2002SchochRR). Eryops megacephalus (Lower Permian); top – reconstruction of the skeleton; bottom – appearance of the animal, sculptor Ya.M. Eglon; exposition of the Orlov Paleontological Museum (Moscow); photo by the author. Anatomical evidences of the ligamentum capitis femoris (LCF) in Eryops megacephalus is suggested by certain features in fossilized pelvic and femoral bones. Notable LCF indicators on the femur include the fovea capitis, the groove on the femoral head, and the femoral head’s tuberosity. In the pelvic bone, signs of LCF presence include acetabular notches, an acetabular fossa, perforations, and irregularities on the acetabular surface. We used th...

A depiction of the circumstances surrounding a hip joint injury—possibly involving the ligamentum capitis femoris (LCF) – which served as the basis for the description of a wrestling match 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.

Homo antecessor. Hip disarticulation

HOMO ANTECESSOR. Hip disarticulation Postmortem separation of the leg from the pelvis in individuals of own species was performed by our evolutionary predecessors. In particular, this was done in the Homo antecessor community, which practiced cannibalism (2003TuttC). Ferna Y. et al. (1999) described evidence of intentional crushing of the femur diaphysis in a young individual (ATD6-76), presumably to extract bone marrow. The bone retained traces of not only several impacts by a striker, but also of an anvil on which the bone lay. The age of the said find in the Gran Dolina cave (Spain) is estimated at about 780 thousand years (1999FernaY_RosellJ). The above features indicate that the femur was initially separated from the soft tissues. In the second stage, the butcher had to use a stone tool to cut the muscles and strong external ligaments of the hip joint. In the next stage, he tore, or perhaps cut off, the ligamentum capitis femoris (LCF) to mobilize the hip and further manipul...

MEDICAL RECORD. Chapter 2

Book manuscript: Arkhipov S.V. Medical Record: The Contribution of a Middle Bronze Age Egyptian Physician to the Book of Genesis. Kyrö: Author’s Edition, 2026. – 312 pp. – 2 tables. – Bibliographical references: 856 entries. play.google.com , books.google.com Introduction Chapter 2 Chronology of the Medical Record CONTENT [i] Text [ii] Navigation [iii] Application [i] Text When reading the Book of Genesis , we learn that the first recorded patient with an injury to the ligament of the head of femur was a man named Ya'akov (Gen. 32:25, 33). In adapted usage, the name is rendered as Jacob. According to the narrative, he was born near the well of Beer-Lahai-Roi, between Kadesh and Bered in the Negev Desert, which is in the south of the "Canaanite" land (Gen. 16:14, 23:19, 24:62). As is clear from the text, the "Canaanite land" is the western part of the current State of Israel, excluding the vicinity of the Jordan River (Gen. 13:11–12). Jacob's father ...
