Twenty years ago, the first mechanical model of the hip joint was made for experimental research. At first, it contained analogues of the acetabular labrum and external ligaments: https://kruglayasvyazka.blogspot.com/2024/05/blog-post_66.html , https://kruglayasvyazka.blogspot.com/2024/05/blog-post_31.html , https://kruglayasvyazka.blogspot.com/2024/05/blog-post_48.html #hip #biomechanics

Original in Russian is available at the link: Нижний портал , below is a machine translation edited by a non-native speaker. Inferior portal FOR HIP ARTHROSCOPY: A PILOT STUDY Arkhipov S.V., Independent Researcher, Joensuu, Finland Introduction Hip arthroscopy is considered a complex and expensive surgical procedure (2015SalasAP). However, it provides a dynamic and accurate assessment of the hip joint, and is recognized as the gold standard for diagnostics (2018JamilM_WittJ). Hip arthroscopy may be one of the last frontiers in sports medicine (2019MaldonadoDR_DombBG). Fig. 1. Compartments of the hip joint (schematic); the central compartment is highlighted in red, the peripheral compartment is highlighted in blue (from 1892PoirierPJ , unchanged). Traditionally, arthroscopic surgeons of the hip joint distinguish three compartments: the central compartment, the peripheral compartment, and the lateral compartment outside the joint, also known as the peritro...

Invention (Patent Application Publication): Mansmann KA. Tendon-sparing implants for arthroscopic replacement of hip cartilage. WO2012162571A1 (2012). The original text of the document contained defects. WO2012162571A1S US Inventor: Kevin A. Mansmann Worldwide applications 2012 WO Application PCT/US2012/039481 events: 2012-05-24 Application filed by Mansmann Kevin A 2012-11-29 Publication of WO2012162571A1 Tendon-sparing implants for arthroscopic replacement of hip cartilage Kevin A. Mansmann Abstract Surgical implant devices are disclosed which will allow completely arthroscopic resurfacing of the acetabular socket, and the femoral head, in hip joints, in both humans, and in animals such as dogs. Such devices, made of flexible polymers with smooth articulating surfaces and porous anchoring surfaces, can be provided with centered openings, to allow a surgeon to spare the major ligament (the ligamentum teres) which connects the femoral head to the pelv...

Abstract of the article Alkalay D, Kollender Y, Mozes M, Meller I. Transarticular tumor invasion via ligamentum teres: A clinical-pathologic study of 12 patients (1998). The authors suggest that ligamentum capitis femoris (LCF) is a potential route for potential route for transarticular spread of a tumor. Quote 1. Abstract We studied 12 patients who were operated on for malignant tumors in and around the hip joint. A correlative study, including preoperative staging studies and anatomical-pathologic aspects of the hip joint, was performed. in 4 of the 12 patients, we found direct histologic evidence of tumor invasion from the head of the femur through the ligamentum teres to the acetabular fovea and vice versa. It seems that the ligamentum teres is a potential route for transarticular spread of a tumor. External links Alkalay D, Kollender Y, Mozes M, Meller I.

Fragments from the book Gray H. Anatomy, descriptive and surgical (1858, first edition ). The selected passages of the "classical" anatomy of the ligamentum capitis femoris (LCF) and original illustrations of Henry Carter. Quote p. 8 1 The cotyloid cavity or acetabulum, is a deep cup-shaped hemispherical depression; formed internally by the pubes, above by the ilium, behind and below by the ischium, a little less than two-fifths being formed by the ilium, a little more than two-fifths by the ischium, and the remaining fifth by the pubes. It is bounded by a prominent uneven rim, which is thick and strong above, and serves for the attachment of a fibro-cartilaginous structure, which contracts its orifice and deepens the surface for articulation. It presents on its inner side a deep notch, the cotyloid notch, which transmits the nutrient vessels into the interior of the joint, and is continuous with a deep circular depression at the bottom of the cavity: this depression...

1844CruveilhierJ

Fragments from the book Cruveilhier J. The Anatomy of the Human Body (1844). The author discusses the anatomy and role of the ligamentum capitis femoris (LCF). Quote p. 94 The head (i, figs. 49 and 50) is the most regularly spheroidal of all the eminences in the skeleton, and forms nearly two thirds of a sphere. In the middle of it we observe a rough depression (k) of variable dimensions, which gives attachment to the round ligament. Quote pp. 159-162 COXO-FEMORAL ARTICULATION (fig. 76). Preparation. Remove with care all the muscles that surround the joint, preserving the reflected tendon of the rectus femoris. The psoas and iliacus muscles, the synovial capsule of which so often communicates with the articular synovial membrane, must be removed with particular care. After the fibrous capsule has been studied upon its external surface, a circular division should be made round its middle portion, for the purpose of uncovering the deep-situated parts. This articulation is the ...

2016ArkhipovaAS Classification of Joints with Flexible Elements.

Classification of Joints with Flexible Elements The classification of joints with flexible elements was first proposed by A.S. Arkhipova in 2016 and presented at conferences in 2016-2017 ( 2017АрхиповаАС ). Joints with flexible elements are divided by the author into detachable and non-detachable, three-axis, two-axis, and single-axis. Each can contain in various combinations one or more external and internal flexible elements - analogs of joint ligaments, including the ligamentum capitis femoris (LCF). Conditional designations of joints with flexible elements using the example of a ball joint: Detachable ball joint with an internal flexible element Non-detachable ball joint with an internal flexible element Detachable ball joint with an external flexible element Non-detachable ball joint with an external flexible element Detachable ball joint with both internal and external flexible elements Non-detachable ball joint with both internal and external flexible elements Flexib...
