Paradox. The necessary is needed by no one

Post in a community for patients after arthroplasty.

A question for the patient community from an implant designer (if the Admin allows it).

Hello everyone, I have a question regarding Total Hip Replacement (THR). As many of you know, dislocations remain a serious risk after surgery. This often happens because a prosthesis lacks the natural ligament that stabilizes a healthy joint. I have developed an experimental prosthesis designed for significantly higher stability. This anti-dislocation effect is achieved by creating an "internal ligament" within the construct. Theoretically, this would allow patients to bring their legs together or sleep on their side without the constant fear of dislocation. In this design, a dislocation would only be possible during extreme leg abduction — but at that point, the muscles are naturally tense, pressing the moving parts of the joint together and providing additional protection.

I would love to hear your thoughts: Is this something patients actually want and need? Or are you generally satisfied with current designs, and feel that nothing needs to change?

Result: deleted, ignored.

The experiments were conducted on a specially designed mechatronic testing rig. The concept of the important role of the ligamentous apparatus is further illustrated by a set of demonstrative mechanical models. The...

Content [i] Annotation [ii] Original text [iii] References [iv] Source & links [v] Notes [vi] Authors & Affiliations [vii] Keywords [i] Annotation Abstract of the article: Michaels G, Matles AL. The role of the ligamentum teres in congenital dislocation of the hip (1970). The authors proposed an analogy for the role of the ligamentum capitis femoris (LCF) as a “ball and chain control” and noted that it can spontaneously reduce congenital hip dislocation. The text in Russian is available at the following link: 1970MichaelsG_MatlesAL . [ii] Original text Quote p. 199 Many papers in the literature have implicated the ligamentum teres as a hindrance to the late open reduction of a congenitally dislocated hip. Occasionally the ligamentum teres has been reported to be absent. However, in most cases it is hypertrophied and elongated. Our present knowledge confirms the fact that congenital dislocation of t...

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. [ii] Introduction According to Rabbinic Judais...

Catalog. Classifications of LCF Pathology

The classifications are intended to systematize of ligamentum capitis femoris pathology and assist in the development of general approaches to its description, registration, analysis and treatment. Keywords ligamentum capitis femoris, ligamentum teres, ligament of head of femur, hip joint, histology, pathological anatomy, pathology, trauma INTRODUCTION In Russia, the initial attempts to classify pathology of the ligamentum capitis femoris (LCF) were made by morphologists. The development of arthroscopic surgery has made it possible to identify various, previously undescribed types of LCF pathology, which prompted the development of various modern classifications based on intraoperative observations. Analysis of literature data and our own morphological observations allowed us to propose a General Classification of the Ligamentum Teres Pathology, which has the form of a collection of classifiers, as well as a Classification of Functions of the Ligamentum Teres. The ...
