Morphometric parameters of the human radial bone head - the basis of an individual approach of its prosthetics

The morphometric parameters of the head of the radial bone are relevant for the manufacture of its prostheses, often in the relevant literature only average sizes are given without taking into account the individual characteristics of their ratios. With insufficiently accurate selection of the sizes of the used prosthesis of the head of the radius, complications arise. To prevent the development of complications, the size of the implant must exactly match the anatomical shape and size of the proximal epiphysis of the radius and the articular surfaces of the ulna and humerus. The purpose of the study is to systematize the data presented in the scientific literature on the anatomical shape, quantitative and qualitative parameters of the head of the human radius for their possible use in the manufacture of prostheses of the radius. The materials and methods of the study consisted in searching for articles and scientific literature in various databases, using the following keywords in Russian and English: elbow joint, radius, head, neck, prosthetics. As a result of the analysis of the literature, it was found that in the study of the elbow joint and the proximal radius, only a few of them are generally accepted indicators used in both anthropometric and clinical studies. The analysis of the literature showed that when characterizing the elbow joint and the proximal radius, the generally accepted indicators used in both anthropometric and clinical studies are three parameters: the maximum and minimum diameters of the head of the radius and the depth of the articular fossa. However, for a more accurate description of the proximal radius, in our opinion, it is necessary to take into account the length of the tuberosity of the radius, the width of the tuberosity of the radius, the sagittal diameter in the area of the tuberosity, the distance between the head and the tuberosity, the width of the head, the depth of the articular fossa, the frontal diameter of the neck, the circumference heads, head diameter in two mutually perpendicular planes, neck circumference, head height in four mutually perpendicular points.
