Abstract:Summary. Hip dysplasia is the most common orthopedic problem in the practice of pediatric orthopedists. A significant problem with hip dysplasia is the divergence of nomenclature units, which is related to different points of view on the pathophysiology of the process. Contemporary conception defines hip dysplasia as a dynamic condition – “developmental dysplasia of the hip (DDH)”, which (in the absence of treatment) worsens with age and leads to the development of early hip osteoarthritis and requires hip rep… Show more

Relevance. Specific hip joint pathologies in children are characterized by insufficiency of the femoral head (FH) coverage by the acetabulum. This is reflected in the contact area reduction between the FH and acetabulum. In order to correct these acetabular deformities properly, the pediatric orthopedist must know in which direction develops a deficit of contact area between the FH and acetabulum and be able to assess the level of this deficit.
Objective: to create an algorithm for the contact area assessment between the FH and acetabulum in children taking into account triradiate cartilage.
Materials and Methods. Pelvic CT scans of a 6-year-old male child without hip joint pathologies were selected. A digital model of the pelvis was created using these CT scans. The pelvic model was transferred to a custom-made software, where the contact area between the FH and acetabulum was assessed in an indirect way.
Results. The algorithm of the contact area assessment between the FH and acetabulum in children that takes into account triradiate cartilage was developed. Using the abovementioned algorithm, the contact area between the FH and acetabulum from both sides was assessed in a 6-year-old male child.
Conclusions. Assessment of the normal contact area between the FH and acetabulum and in various pathological conditions in children will help pediatric orthopedists to understand better different hip joint pathologies and improve preoperative planning.

“…Developmental dysplasia of the hip (DDH) is one of the commonest hip joint pathologies in pediatric orthopedist practice [1]; without treatment, it leads to early hip arthritis [2]. In younger patients, treatment is usually nonsurgical, but in older patients (who began to walk), surgical treatment is preferable [3].…”
Introduction. Developmental dysplasia of the hip (DDH) is one of the commonest hip joint pathologies in children; to treat it properly, hip surgeons should know the normal femoral head (FH) coverage by the acetabulum. This paper aims to assess the femoral head coverage in healthy children younger than 6 years. Methods. 270 hip joint CT scans were selected, and digital pelvic models were created according to these scans. FH coverage by the five acetabular regions was assessed according to patient’s age and sex. Results. Normal reference values of FH coverage by different acetabular regions were obtained. It was found that the growth process of different acetabular regions occurs nonlinearly with the periods of acceleration. Anterior and superior-anterior acetabular regions grow more intensively in boys up to 3 years old and between 4 and 5 years old both in boys and girls; superior-posterior, posterior-superior, and posterior-inferior acetabular regions grow more intensively in boys and girls up to 3 years old and between 4 and 5 years old (
