Lesions of Ligamentum capitis femoris as a cause of the necrotic changes in Articulatio coxae

Abstract

Aim of the research There is more and more research on one rather underestimated object, which is a part of the hip joint - namely Ligamentum capitis femoris. Many doctors still believe that it plays a minor role in joint trophism, but a number of studies disprove this. The present study aims to demonstrate the lesions that occur in the hip joint when the Ligamentum capitis femoris (also known in literature as Ligamentum teres) is found damaged, with a focus on the blood vessels going alongside the ligament and supplying the head of the hip joint. The aim of the study is to demonstrate the pathological changes that occur in the hip joint due to obstruction of the arterial vessel entering the joint together with the ligament. This vascular change can be a result of many factors - traumatic, septic and aseptic. Materials and Methods To achieve our goals we set the following main tasks: to examine the structure of Ligamentum capitis femoris with an optical microscope after staining the samples with Hematoxylin Eosin and AZAN and to make a comparative complex analysis of the morphological characteristics of Ligamentum capitis femoris in humans. Results The examination of ligaments from cadavers - which have pathological changes in the hip joint - clearly shows the damage of the Ligamentum capitis femoris. Conclusions From the histological examination we conducted, we found that Ligamentum capitis femoris has a biological, mechanical and trophic role in the hip joint and its preservation is important in preventing future complications.
