Evaluation of the morphological and morphometric characteristics of the acetabulum in the Anatolian population

Abstract

Objectives: The aim of our study was to investigate the shape, variations and dimensions of the acetabulum, which has an important place in the structure of the hip joint and is of great importance in terms of surgical interventions and compliance with hip joint prostheses, in the Anatolian population. Methods: A total of 45 coxal bones, 24 right-sided and 21 left-sided, were evaluated. The anterior ridge of the acetabulum was classified into four types: straight, curved, angular and irregular. The transverse diameter (TD), posteroinferior-vertical diameter (VD), acetabular depth (AD) and width of the acetabular notch (WAN) were measured using a digital caliper. Results: Seven (15.6%) acetabula had straight, 23 (51.1%) had curved, 9 (20%) had angular and 6 (13.3%) had an irregular anterior ridge. The measurements were as follows; TD: 52.3±4.7 mm; VD: 54±4.4 mm; WAN: 26.3±3.6 mm; and AD: 25.3±3 mm. There was no significant difference between the right and left sides for any of the morphometric measurements. Conclusion: Our study revealed that the most common anterior acetabular ridge shape was curved on both sides of the coxal bone and showed that acetabular morphometry did not vary by side.
