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...

«Prof. Partridge in his lectures on anatomy at King's College was accustomed to compare the Ligamentum Teres, in its function, to the leathern straps by which the body of a carriage is suspended on springs » ( 1874SavoryWS ). Perhaps Nikolai Pirogov listened to these lectures ( 1859PirogoffN ). The analogy that Richard Partridge used could have arisen after reading the monograph Bell J. The Principles of Surgery (1801) . In it, the author depicted a cart and a pelvis resting on the head of one and two femurs. However, there is no mention of ligamentum capitis femoris (LCF) in the chart descriptions.

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.

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.

Abstract of the article Chen HH, Li AF, Li KC, Wu JJ, Chen TS, Lee MC. Adaptations of ligamentum teres in ischemic necrosis of human femoral head (1996). The authors investigate the strength of the ligamentum capitis femoris (LCF) in avascular necrosis and femoral neck fracture. The text in Russian is available at the following link: 1996ChenHH_LeeMC . Annotation Little is known about the biomechanical properties of human ligamentum teres. To more fully understand the ligamentum teres, its dimensions and mechanical properties were measured in 22 cases of acute fracture of the femoral neck and 21 cases of ischemic necrosis of the femoral head. The specimens first were preconditioned and then loaded to failure with a testing machine at a fast strain rate of 100% s(-1). The ischemic necrosis group had a significantly larger volume (3.09 +/- 1.81 ml versus 1.30 +/- 0.62 ml) and cross section area (65.3 +/- 59.1 mm2 versus 30.6 +/- 27.2 mm2) than did the acute f...
