Homo neanderthalensis

HOMO NEANDERTHALENSIS

Homo neanderthalensis flourished 500-30 thousand years ago in Europe and Asia. It is assumed that its ancestor could have been Homo ergaster or Homo heidelbergensis (2005KleinR).

A reconstruction of the pelvis of the Neanderthal "Kebara 2" (Israel), whose remains are dated to 64-59 Kya (2021AdegboyegaMT_WeaverTD), is known. The well-preserved right pelvic bone (Fig. 1) has a large acetabulum with fossa and acetabular notch, indicating the presence of ligamentum capitis femoris (LCF).

The configuration of the acetabulum of Homo neanderthalensis leaves no doubt about the presence of LCF in this species. Additional evidence is the fossa of the femoral head. We were unable to personally examine the femoral head of Homo neanderthalensis with a fovea for LCF. The presence of the said structure in Homo neanderthalensis is confirmed in the dissertation of K.H. Tamvada (2015), which examines in detail the biomechanics of the femur of this species. In particular, the author, modeling the proximal femur and its movements, identifies the fovea capitis node «to imitate the ligamentum teres».

According to the author, the ligamentum capitis femoris (LCF) reduces shocks and impacts of the articular surfaces. In addition, P. Lesshaft states an anatomical fact: the LCF is located vertically under the part of the acetabulum, which mainly bears the weight of the body. The text is prepared for machine translation using a service built into the blog from Google or your web browser. In some cases, we have added links to quotations about LCF available on our resource, as well as to publications posted on the Internet.

Fragment from the book Drake J. Anthropologia nova: or, a new system of anatomy. … The Third Edition Corrected. (1750). The author does not name the ligamentum capitis femoris (LCF), but accurately describes its appearance (short, thick, and round), and indicates the attachment points. Quote p. 432 CHAP. VIII. Of the Bones and Muscles of the Thigh, Leg and Foot … The first of these is the largest and most prominent, and has a large round Head, capp’d with a Cartilage, which is receiv’d into the Acetabulum or Socket, at the Ischium or Os Coxendicis; to which it is fastned by two Ligaments: One broad, thick, and membranous, surrounding the whole Edge of the Acetabulum, and Head of the Bone: The other short, thick, and round, springing from the bottom of the Acetabulum, by the side of the Mucilaginous Gland, (which is here the most considerable of the whole Body) and is inserted into the middle of the Cartilaginous Head.

1851HyrtlJ

The author expresses a classic view on the functions of the ligamentum capitis femoris (LCF): a conductor of blood vessels and a limiter of adduction of the femur. J. Hyrtl believed that it was impossible to completely dislocate the hip without tearing the LCF. Hyrtl J. Lehrbuch der Anatomie des Menschen, mit Rücksicht auf physiologische Begründung und praktische Anwendung. Wien: W. Braumüller, 1851. [fragment] Quote p. 265 In der Höhle des Gelenks liegt das runde Band des Schenkelkopfes (Lig. teres), welches an der Incisura acetabuli entspringt, und bei richtiger Neigung des Beckens, senkrecht zur Grube des Schenkelkopfes aufsteigt. Es beschränkt dieses Band die Zuziehung des Schenkels, und schreibt zugleich den durch die Incisura acetabuli eindringenden Blutgefässen den Weg vor, den sie zum Oberschenkelkopfe zu nehmen haben. Da das Band, wenn es in die Höhle des Gelenkes vorragen würde, durch Reibung viel zu leiden hätte, so...

1877MorrisH

An excerpt from the article by Morris H. Dislocations of the Thigh: their mode of occurrence as indicated by experiments, and the Anatomy of the Hip-joint (1877, pp. 161-170). The author noted that the ligamentum capitis femoris (LCF) is stretched during flexion, adduction, and external rotation. It was found that the LCF is always damaged in hip dislocations, is more often torn from the femur, and is rarely ruptured. Discussion of article see article 1877BrookeC . DISLOCATIONS OF THE THIGH: THEIR MODE OF OCCURRENCE AS INDICATED BY EXPERIMENTS AND THE ANATOMY OF THE HIP-JOINT.

RECENTLY, whilst making various dissections of the hip-joint, the usually accepted doctrine that dorsal and ischiatic dislocations of the femur occur when the thigh is in a position of adduction appeared to me as very improbable, on anatomi...
