FACEBOOK GROUP

The LIGAMENTUM CAPITIS FEMORIS group

has been created on the social network facebook.

This is a community for discussing Ligamentum capitis femoris (Ligament of head of femur, Ligamentum teres; Ligaments of the head of the femur). It is supposed to exchange opinions, observations, research results. The knowledge gained will help to improve diagnostics, treatment and prevention of injuries, as well as diseases of the hip joint. The administrator believes that ligamentum capitis femoris, still ligamentum incognitum, will finally leave the "gray zone" of science.

Welcome to the group!

Who, When, and Where Wrote the Book of Genesis?

Who, When, and Where Wrote the Book of Genesis? A Medical Hypothesis By Sergey V. Arkhipov, MD, PhD & Lyudmila N. Arkhipova, BSN CONTENT [i] Abstract [ii] Introduction [iii] Egyptian physician [iv] Asian diviner [v] Conclusion [vi] References [vii] Application [i] Abstract The Book of Genesis is an example of an ancient literary text that contains important medical insights. We propose that it was written in northern Egypt in the late 17th century BCE, approximately ten years after the Minoan eruption. The protograph likely emerged from the collaboration between an Asiatic seer, who rose to the rank of an Egyptian official, and an Egyptian physician-encyclopedist. By refining its dating and authorship, this hypothesis positions Genesis as a credible source of medical and historical data, thereby enhancing its value for interdisciplinary research. [ii] Introduction According to Rabbinic Judais...

Test catalog of the LCF pathology

Test catalog of the ligamentum capitis femoris pathology By Sergey V. Arkhipov, MD, PhD CONTENT [i] Abstract [ii] Introduction [iii] Testing in the supine position [iv] Testing in a standing position [v] Gait study [vi] References [vii] Application [i] Abstract A description of tests for the detection and differential diagnosis of ligamentum capitis femoris (LCF) pathology is presented. [ii] Introduction One of the first studies devoted to the diagnosis of LCF injury demonstrated a variety of symptoms: groin pain, hip stiffness, sometimes long-standing minimal clinical findings, or signs similar to osteoarthritis (1997GrayA_VillarRN). More than a decade later, researchers concluded: "Unfortunately, there is no specific test for detecting LCF tears." The signs known at that time were nonspecific and were also observed in other intra-articular pathologies of the hip joint (2010CerezalL_Pérez-CarroL). The a...

Key Role of the LCF

In the experiments conducted on the pelvis-femur-muscle-ligaments model, we found that when the contralateral pelvic drop occurs, the ligament of the head of femur become maximally tense; simultaneously, there is relaxation and lengthening of the gluteus medius muscle; the pelvis spontaneously rotates towards the stance limb (forward), and the load on the hip joint decreases. Thanks to the functioning of the ligament of the head of femur the walking is smooth, rhythmic, and energy-efficient.
