Homo naledi

 

HOMO NALEDI

The species Homo naledi inhabited southern Africa from 335,000 to 236,000 years ago (2017DirksPH_BergerLR).

Among the preserved remains of Homo naledi there is a femoral head (UW 101-1300) without a lateral surface. On it, the fossa of the femoral head is clearly visible, measuring 8.6 by 6.6 mm. It is deeply pitted with several holes inside. (2016MarchiD_DeSilvaJM:Fig.9). This observation provides clear evidence for the presence of a ligamentum capitis femoris (LCF) in Homo naledi, specifically the distal attachment site.

Homo naledi pelvic remains are small fragments of the ilium, ischium, pubis, and sacrum (2018VanSickleC_HawksJ). None of the parts contain an acetabulum, which could be used to differentiate the proximal attachment site of the LCF.

ChatGPT. Scientific Review On the Article: “Why Acetabular Labrum Repair May Be Ineffective”

  At our request, the language model ChatGPT, prepared to assist in the analysis and editing of texts by OpenAI, 2025, wrote a review of the article by  Arkhipov SV.   Why Acetabular Labrum Repair May Be Ineffective: A Note on the Mysterious ‘Dark Matter’ in the Hip Joint   ([Ru]  Архипов СВ .  Почему восстановление вертлужной губы может быть неэффективно?: Заметка о таинственной «темной материи» в тазобедренном суставе.  06.04.2025 ).  The original article was reviewed and edited based on the recommendations of Grok , an artificial intelligence developed by xAI. In accordance with the comments of both reviewers, the article was corrected and published.

1836WeberW_WeberE

  We present fragments from the book that laid the foundation of biomechanics of the hip joint considering the ligamentum capitis femoris (LCF). The authors experimentally proved that this structure is situated in the frontal plane when the body is in a vertical position. Analysis of observations showed that when standing on one leg, the LCF and the anterior portion of the iliofemoral ligament (pars descendens lig. iliofemoralis) are stretched and hold the pelvis. These ligaments counteract the weight of the body along with the head of the femur on the same side. The insight of the Weber brothers was later developed in the works of H. von Meyer (1856) , W. Turner (1857) , and W. Savory(1874) . Weber W, Weber E. Mechanik der menschlichen Gehwerkzeuge: eine anatomisch-physiologische Untersuchung. Gottingen: Dietrichsche Buchhandlung, 1836.

1922LeeserI

  A fragment of the Book of Genesis tells about the journey of the family of Patriarch Jacob from Charan to Canaan (Gen. 31:1 – 33:20). The translation into English from of the Masoretic Hebrew text of the Torah was done by Isaac Leeser ( 1922 LeeserI ). «Most scholars agree that the texts now found in Genesis began to be written down sometime after the establishment of the monarchy in Israel in the tenth century BCE» (1992SuggsMJ_MuellerJR). A selected passage from an ancient work mentions for the first time in history the injury of the ligamentum capitis femoris (LCF) of a person is mentioned (Gen. 32:26,33). In the original Hebrew source this anatomical element is referred to as «גיד» (gheed, gid)  ( Bereshit 32:33 ;  1923, 2004PreussJ;  2019ArkhipovSV_SkvortsovDV ;  2020ArkhipovSV_ProlyginaIV ).  This term was recorded in writing long before Hippocrates of Kos (V-IV cent. BCE) who used the concept «νεῦρον» to designate LCF (1844LittréÉ). It is not known...

ILIOTIBIAL TRACT & LCF

  ILIOTIBIAL TRACT & LCF There is an opinion that the iliotibial tract, like the ligamentum capitis femoris (LCF), provides pressing of the acetabulum to the lower surface of the femoral head. I think that this is not true. The tract is located above and lateral to the center of rotation of the hip joint. Its force vector, like the force vector of the abductor group of muscles, presses the acetabulum to the upper part of the femoral head, which increases the load on it. The ligamentum capitis femoris acts in the opposite direction. Below is a diagram for a single-support position. #ligamentum_teres   #hip   #biomechanics   #ligamentum_capitis_femoris Publication in the facebook group 04/12/2025.                                                                              ...
