Human LCF intersection

HUMAN LCF INTERSECTION In the south of China, in the Guangxi Zhuang Autonomous Region, the archaeological Neolithic site of Dingsishan was investigated. Burials of 355 people were found in this place. The authors of the article (2024YeZ_LiFJ) identified 91 skeletons with traces of manipulations with the remains. They are attributed to burials of the Dingsishan III-IV phase, aged 8.0-4.5 thousand years. 13 notches were found on the proximal part of various femurs. « Cutmarks on the femoral head, neck and intertrochanteric line, as well as along the medial linea aspera of the femoral shaft, suggest that soft tissue around the hip, including the iliofemoral ligament and the iliacus and adductor muscles, was severed to disarticulate the joint.» This and other postmortem bone injuries «... suggests that corpse treatment at Dingsishan included disarticulation » (2024YeZ_LiFJ). Figure 4 of the cited article shows the distribution and direction of cutmarks on human skeletons from Dingx...

Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

1869BigelowHJ

Fragments from the book Bigelow HJ. The mechanism of dislocation and fracture of the hip (1869). The author discusses broken of the ligamentum capitis femoris (LCF) in hip dislocations. Quote p. 10 In the spring of 1861, having been led to expose a joint, the luxation of which had been the subject of a lecture, I was agreeably surprised to observe the simple action of the ligament, - a simplicity which subsequent experience has confirmed, and which strikingly explains the phenomena observed in the living subject (1). The dislocated joint alluded to presented on examination the following appearances. 1. Great laceration of the muscles about the joint. 2. The ligamentum teres broken . 3. Laceration of the inner, outer, and lower parts of the capsule. 4. The anterior and upper parts of the capsule uninjured, and presenting a strong fibrous band, fan-shaped and forked. Quote p. 18 FIG. 1. — The Y ligament, showing its inner and outer fasciculi. The form...

Inferior Portal. Part 1.

Original in Russian is available at the link: Нижний портал. Часть 1. below is a machine translation edited by a non-native speaker ( version dated 03/02/2025 ) . INFERIOR PORTAL FOR HIP ARTHROSCOPY: A PILOT STUDY PART 1. Background and Hypothesis Arkhipov S.V., Independent Researcher, Joensuu, Finland Abstract: The article presents, theoretically and graphically substantiates the technique of a new arthroscopic approach to the central compartment of the hip joint. It is proposed to introduce the optical system of the arthroscope from below through the acetabular notch without traction. Similar approaches were used for puncture, arthroscopy, arthrography, and arthrotomy of the hip joint. Diagnostics using the described lower portal will exclude complications caused by distraction of the leg and compression of the perineal support during surgery. CONTENTS PART 1.
