Aim: The acetabulum is a pit located on the outer surface of the hip bone and articulates with the femur head. It consists of three bones: Os Ilium, Os Ischii, Os Pubis. The joining of these three bones starts at 14-16 years and continues until the age of 23. The purpose of this study is to assist clinicians in hip operations by performing morphometric measurements of the acetabulum.
Methods: In this observational study, Os Coxae in the bone collection were measured in the anatomy laboratory. 96 Os Coxa (50 right, 46 left) were used in the Anatomy Department of Erciyes University. With the help of a digital caliper, the following nine parameters were measured on the left and right dry bones separately and evaluated: The mean length between Corpus Ischii acetabulum edge and the acetabulum anterior edge (CIAE-AAE), transverse diameter of Incisura Acetabulum (IATD), Incisura Acetabulum length (IAU), mean acetabulum depth (AD), mean length between the edge of the acetabulum on the inferior side of Spina Iliaca Anterior and the posterior edge of the acetabulum (SIAIAK-AKU), facies lunata area, Limbus Acetabuli length, mean length between the midpoints of Incisura Acetabuli and limbus, and the shape of the acetabulum. The images obtained from the dry bones were transferred to the computer and the area of Facies Lunata and the length of Limbus Acetabuli were calculated with ImageJ program.
Results: The parameters measured on the right and left sides, respectively, were as follows: CIAE-AAE: 53.04-54.67 mm, IATD: 50.57-51.44 mm, IAU:18.08-20.25 mm, AD: 24.87-22.85 mm, SIAIAK-AKU: 52.38-45.63 mm, mean Facies Lunata area 13.25-13.65 cm2, Limbus Acetabuli length 13.65-3.61 cm (mean 13.63 cm), mean distance between the midpoints of Incisura Acetabuli and limbus: 56.45-57.12 mm. The acetabulum was straight in 41 bones, irregular in 8, inclined in 27 and angular in 20.
Conclusion: We think that these index values of acetabulum we obtained will contribute to clinicians and the literature in hip dislocation and total hip surgeries.
