Morphologic and Morphometric Evaluation of the Acetabulum

Abstract

Objective: The aim of this study is to reveal the morphological and morphometric features of the acetabulum and to compare them with the current literature. Materials and Methods: A total of 57 coxae (29 left, 28 right) were examined. The anterior ridge of the acetabulum was classified as curved, straight, angular, and irregular according to its morphological features and the transverse diameter of the acetabulum (TD), the vertical diameter of the acetabulum (VD), the anteroposterior diameter of the acetabulum (APD), acetabular depth (AD), acetabular notch width (ANW) and os coxae height (CH) were measured. Results: The types of the anterior ridge of the acetabulum were found as 19 (33.3%) straight, 18 (31.6%) curved, 14 (24.6%) angular, and 6 (10.5%) irregular in shape. The mean values of the TD, VD, APD, ANW, AD and CH were 50.67±3.12 mm, 52.21±3.52 mm, 52.66±3.73 mm, 22.64±2.67 mm, 29.75±2.28 mm and 206.33±11.70 mm respectively. No significant difference was found between the right and left coxae in terms of the measured parameters (p>0.05). There was only a difference between the shapes and the depth of the acetabulum (p<0.05). Conclusion: Knowing the normal anatomy of the acetabulum is important in preventing complications during surgical procedures of this area.

Acetabulum’un Morfolojik ve Morfometrik Olarak Değerlendirilmesi

Öz

Amaç: Bu çalışmanın amacı acetabulum’un morfolojik ve morfometrik özelliklerini ortaya koymak ve literatürde yapılan benzer çalışmalar ile karşılaştırmaktır. Materyal ve Metod: Toplam 57 os coxae (29 sol, 28 sağ) incelendi. Acetabulum’un ön kenarı morfolojik özelliklerine göre kavisli, düz, açılı ve düzensiz olarak sınıflandırıldı ve acetabulum’un transvers çapı (TÇ), acetabulum’un vertikal çapı (VÇ), acetabulum’un ön-arka çapı (ÖAÇ), incisura acetabuli genişliği (İAG), acetabulum derinliği (AD) ve os coxa (os coxae olarak yazılacak) yüksekliği (CY) ölçüldü. Bulgular: Acetabulum ön kenarı coxa’ların 19’unda (%33,3) düz, 18’inde (%31,6) eğri (kavisli olarak yazılacak), 14’ünde (%24,6) köşeli (açılı olarak yazılacak), 6’sında (%10,5) düzensiz şekilli olarak bulundu. TÇ, VÇ, ÖAÇ, İAG, AD ve CY'nin ortalama değerleri sırasıyla 50,67±3,12 mm, 52,21±3,52 mm, 52,66±3,73 mm, 22,64±2,67 mm, 29,75±2,28 mm ve 206,33±11,70 mm idi. Sağ ve sol acetabulum ölçümleri arasında anlamlı fark bulunamazken(p>0,05), acetabulum derinliği ile acetabulum ön kenar şekli arasında anlamlı fark bulundu (p<0,05). Sonuç: Acetabulum’un normal anatomisinin bilinmesi bu bölgenin cerrahi işlemleri sırasında komplikasyonları önlemede önemlidir.
