[i] The femoral head ligament was typical, extending from the femoral head fovea to the acetabular fossa [24,25]. (24. König, H.E.; Liebich, H.G.; Maierl, J. Hindlimbs or pelvic limbs (membra pelvina). In Veterinary Anatomy of Domestic Animals: Textbook and Colour Atlas, 7th ed.; König, H.E., Liebich H.G., Eds.; Thieme: Sttutgart, Germany, 2021; pp. 243–303.  ;  25.

[ii] In addition to the capsule and labrum, there are multiple other contributing factors to the suction seal including the surrounding joint fluid, ligamentum teres, and extra-capsular muscle tone.

 

[iii]   … ligamentum teres tear all aided in establishing a diagnosis of symptomatic hip instability.

 

[iv] The choice of treatment tactics was carried out taking into account the type of fracture according to the Pipkin classification and clinical data. Systematized according to the following types: – I — dislocation of the hip with a fracture of the head of the femur below the point of attachment of the round ligament (pit of the head); – II — dislocation of the hip with a fracture of the head of the femur above the point of attachment of the round ligament; – III — type I or II in combination with a femoral neck fracture; – IV — type I or II together with a fracture of the acetabulum.

  

[v] The ligament of the femoral head, also known as ligamentum teres, originates from the obturator crest and inserts into fibrous capsule of the hip joint.

  

[vi] Recent research suggests that the development of cam morphology is related to the repetitive shear stresses experienced at the hip joint during adolescence from skating. This condition likely increases the potential for intra-articular and extra-articular injuries in these athletes later in their careers. Research also indicates that the hip joint mechanics during forward skating substantially increase the possibility of sustaining a labral tear compared to other sports. Such an injury can increase femoral head movement within the joint, potentially causing secondary damage to the iliofemoral ligament, ligamentum teres and joint capsule. These injuries and the high density of nociceptors in the affected structures may explain the high prevalence of hip and groin pain in hockey athletes.

The most common hip pathologies observed in elite hockey athletes include: femoroacetabular impingement (FAI), injuries to the non-contractile tissues including the labrum, iliofemoral ligament (IFL), and ligamentum teres (LT), as well as muscular injuries, such as core muscle injuries (CMI), hip flexor, and adductor injuries.

  

[vii] Introduction. This study aims to evaluate the histology of the ligamentum teres and its relationship with matrix metalloproteinases (MMPs) and a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS), which are involved in the destruction of extracellular matrix proteins in patients with developmental dysplasia of the hip (DDH).

Conclusions. The histological structure of ligamentum teres in patients with DDH shows moderate inflammation, fibrosis, neovascularization, hyalinization, and fatty infiltration regardless of age and radiological stage. ADAMTS-7, MMP-2, and MMP-9 correlate positively with the histological parameters of the ligamentum teres in patients with DDH.

  

[viii] The femoral head is approximately rounded and features a shallow pit known as the capital ligament fossa (as shown in Fig. 4I).

 

[ix] [There is an] … oblique ligament groove on the femoral head…

 

[x] The hip is further stabilized by static and dynamic stabilizers, including the fibrocartilaginous labrum, ligamentous hip capsule, ligamentum teres, and the musculature that courses across the hip joint.

[xii] At 6 weeks of age (mean weight = 10.6 ± 1.8 kg, range = 8.1–14.5 kg), piglets underwent surgery to induce complete (100%) ischemia of the epiphysis of the femoral head by placement of a ligature around the femoral neck and transection of the ligamentum teres.

Complete femoral head ischemia was confirmed in 10/11 piglets as determined by the complete absence of signal enhancement on subtracted CE-MRI. One piglet had partial femoral head ischemia and thus was excluded from the data analysis. In all cases, femoral head ischemia was limited to the epiphysis of the femoral head, whereas the metaphysis was perfused.

  

[xiii] The head of the femur is oriented medially and slightly ventrally in anterior view (Fig. 2A1). It has a rounded, semicircular outline, but poor preservation makes interpretation of other features difficult. For example, there appears to be a distinct ligament groove on the anterior surface extending parallel to the medial margin of the process, but this could be the result of erosion or damage as there is no cortical bone in this area.


[xiv] Abstract. In the past, the ligamentum teres of the hip joint was considered as a vestigial structure and its removal during surgical procedures was deemed acceptable. However, with the recent advancements in hip arthroscopy, there has been an increased interest in ligamentum teres injuries. This has led to various studies revealing notable characteristics of this ligament. The purpose of this review article is to describe the role of the ligamentum teres as a stabilizing factor in the hip joint, focusing on its anatomical and biomechanical characteristics. In addition, by identifying the causes of ligamentum teres injuries, we aim to present appropriate diagnostic methods and treatment approaches. Ultimately, we intend to provide comprehensive guidelines for the ligamentum teres injuries.

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 ).

50 TABLES OF EVIDENCE

  Ancient Egypt is the birthplace of the Book of Genesis Arkhipov S.V. 50 Tables of Evidence for the Composition of Genesis in Late Second Intermediate Period Egypt: The Protograph Before the Oral Tradition. Joensuu : Author's Edition, 2026. GGKEY: ZPYTRNR69CB  https://play.google.com/store/books/details?id=Dw7PEQAAQBAJ http://books.google.com/books/about?id=Dw7PEQAAQBAJ ASIN: B0GXWTLSLK https://www.amazon.com/dp/B0GXWTLSLK Synopsis This monograph presents a fundamental revision of the dating and origin of the Book of Genesis , challenging the dominant hypothesis, which dates the text to the mid-first millennium BCE. Through a systematic analysis presented in 50 comparative tables, the author argues that the protograph of Genesis was a deliberate literary compilation created in Egypt during the late Second Intermediate Period (ca. 17th–16th centuries BCE), shortly after the Minoan eruption. The core of the research concerns the non-oral origin of the text. By ident...
