[i]  Ligamentum teres may play a role in hip stability in cases of mild dysplasia.

 

Similar to this, intraoperative causes [instability] may include ligamentum teres debridement, iliopsoas tenotomy, labral debridement, over-resection of the acetabular rim, and unrepaired capsulotomy.

  

[ii]  Impingement between the cam lesion and the lateral acetabular rim restricts hip abduction, a condition known as hinge abduction. This restriction is often accompanied by associated pathologies, such as synovial proliferation, ligamentum teres tears, loose bodies, labral tears, and cartilage damage, ultimately leading to early-onset osteoarthritis [8–12].

 

[iii] Femoral head osteochondral allograft transplantation …

During the procedure, the patient is placed in a lateral decubitus position under general anesthesia. A lateral approach facilitates exposure of the peri-trochanteric space, and a trochanteric osteotomy is performed with an oscillating saw. In cases where the patient exhibits increased soft tissue laxity and hypermobility, a trochanteric osteotomy is not required to facilitate joint exposure. Careful elevation of the abductor and iliocapsularis permits visualization of the capsule, which is cut in a Z-fashion. Once the femoral head is exposed, the ligamentum teres is cut, and the femoral head is dislocated anteriorly.

  

[iv] MRI can provide high-resolution imaging of the labrum, articular cartilage, and ligamentum teres, …

 

[v] The function of the ligamentum teres in the mature adult has previously   not been well defended, but the ligamentum teres is felt to provide some stability to the hip.

 

The treatment of ligamentum teres rupturesis generally arthroscopic debridement and local synovectomy.

  

[vi] … slipped capital femoral epiphysis … [Two joints]

 

[One side The other side.] The ligamentum teres was functionally absent. 

[Other side] The ligamentum teres was again absent.

 

[vii] The femoral head sits in the acetabulum of the pelvis, within the anterior and posterior columns and is secured by fibrocartilage and ligamentous structures, including the acetabular labrum and the ligamentum teres.

  

[viii] While labrum repair in addition to osteoplasty remains the standard of treatment for FAIS, there is a subset of FAIS patients that present with labral tears that are not amenable to repair, such as in the case of large segmental defects or severe labral degeneration. To address these issues, labral reconstruction was introduced in 2009 by Sierra and Trousdale. Their initial report used a resected ligamentum teres capitis autograft to reconstruct five patients with relatively favorable results [2]. This technique has since been adopted and modified to produce reliably favorable outcomes [3-7].

[xi] … the transverse acetabular ligament adherent here to the ligamentum teres (aka the ligament of the head of the femur). The other end attaches to the pit in the head of the femur (fovea femoris).

 

There is a small branch from the lateral branch of the obturator artery that travels into the ligamentum teres into the hip joint and which typically obliterates in adolescence. This is important since it limits the blood supply to the head of the femur…

   Palmerani Á , drawing Jacob wrestling with the angel (1802 ).  Depicting the circumstances and mechanism of the ligamentum capitis femoris (LCF) injury based on the description in the Book of Genesis: 25 And Ja cob was left alone; and there wrestled a man with him until the breaking of the day. 26 And when he saw that he could not prevail against him, he struck against the hollow of his thigh ; and the hollow of Jacob's thigh was put out of joint, as he was wrestling with him. … 33 Therefore do the children of Israel not eat the sinew which shrank, which is upon the hollow of the thigh, unto this day; because he struck against the hollow of Jacob's thigh on the sinew that shrank.  ( 1922LeeserI , Genesis (Bereshit) 32:25-26,33) More about the plot in our work:  Ninth month, eleventh day   ( 2024 АрхиповСВ.

The First Animals

  THE FIRST ANIMALS According to molecular clock data, the separation of the Animal Kingdom from the Plant Kingdom occurred 1609±60 Ma (2004HedgesSB_ShoeJL). Molecular estimates indicate that the last common ancestor of multicellular representatives of the fauna (Metazoa) was Neoproterozoic, most likely younger than 800 million years (2015PisaniD_LiuAG). Biomarkers of metazoan living systems identified in sedimentary deposits indicate their presence in the seas since the Cryogenian period (2018ZumbergeJA_SummonsRE), which began around approximately 720 Ma (2023CohenKM_CarN). Multicellular animals were part of early Ediacaran ecosystems and are found below layers dated to 632.5 ± 0.5 Ma (2007Yin_LHuJ). The oldest fossil of a multicellular organism resembling a sponge (Porifera) is about 600 Ma (2015YinZ_TafforeauP). The last Neoproterozoic glaciation (about 582 Ma) coincides with the appearance of complex organisms in the fossil record (2007BowringSA_AllenPA). Ev...

Homo floresiensis

  HOMO FLORESIENSIS Homo floresiensis lived on the island of Flores (Indonesia) 190-50 Kya (2016SutiknaT_RobertsRG). The ancestor of this species is «suspected» to be the Asian subtype Homo erectus, which arrived from the mainland about 800 Kya (2009LyrasGA_DeVosJ). The anatomy of Homo floresiensis is less similar to Homo habilis (2008Gordon_WoodB). Homo floresiensis Author: Cicero Moraes et al.  (Arc-Team)  ; source: wikimedia.org   collection (license CC BY 4.0, no changes). Among the discovered remains of a female Homo floresiensis  ( humanorigins . si . edu )  there is a relatively well-preserved left pelvic bone (LB1/7). It has a « typically human » acetabulum (2009JungersWL_DjubiantonoT:Fig.3). The acetabulum has a complete fusion of the three bones that form it and is not hypoplastic (2012BrownP:Fig.4). The acetabular fossa is rounded and deep, continuing downwards and forwards as a wide acetabular notch. This area is the site of attachment and func...

Human Children. Retelling of Chapter 10

      Short retelling of chapter 10 of the essay: Arkhipov S.V. Human Children: The Origins of Biblical Legends from a Physician's Perspective. Joensuu: Author's Edition, 2025. [In Russian]  Chapter 10. THE ARK AND THE CAVE The Book of Genesis does not specify where Noah lived before the flood, but it is plausible his home was in the "land of Nod." To save his family and terrestrial animals, Noah builds an ark measuring "three hundred cubits" long, "fifty cubits" wide, and "thirty cubits" high, coated with pitch inside and out. The vessel has three decks, a pyramidal roof, a side door, and a window, likely at the top. Noah loads his wife, three sons with their wives, and representatives of birds, reptiles, and "clean and unclean cattle." The text lists some "passengers": Noah’s sons, Shem, Ham, and Japheth, and mentions "beasts," "cattle," "creeping things," "flying creatures,"...
