Determination of the acetabular morphology and orientation is important for the total hip arthroplasty applications. In general, preoperative planning for these patients is done on true hip X-rays in orthopedics clinics. But those evaluations may not represent the acetabular architecture in detail, because of 2 dimensional images. The aim of this study is to determine the acetabular morphology of a healthy Turkish adult population sample through examination of acetabular parameters on 3-dimensional computed tomography (CT)-based images according to side and gender. A retrospective evaluation was made of acetabulum CT scans taken for various reasons in a healthy Turkish population sample. The examination parameters were defined as measurements of the acetabular anteversion angle, acetabular abduction angle, lateral center edge angle, acetabular width, acetabular depth, sagittal acetabular angle, and medial wall thickness values. The CT scans including the bone structure were examined of a total of 252 hips of 126 patients. The acetabular index was calculated as depth/width × 100. Lateral center edge angle of < 20° with medial wall thickness > 5 mm was accepted as a criterion of dysplasia of the acetabulum. Evaluation was made of the acetabular CT scans of 73 females and 53 males with a mean age of 44.64 ± 12.31 (19-68) years. A statistically significant difference was determined between the sides in respect of acetabular anteversion angle (P = .007) and between the genders in respect of acetabular depth and acetabular width (P = .001, P = .001). The prevalence of dysplasia was determined to be 1.6% for the whole study group, as 1.9% in males and 1.4% in females. In the current study sample there were parametric differences between sides and genders in terms of acetabulum morphology and orientation. Further studies of larger series will be able to provide a better representation of the Turkish population.
确定髋臼形态和方向对于全髋关节置换术非常重要。一般来说，这些患者的术前规划是在骨科诊所的真实髋关节 X 光片上进行的。但由于二维图像，这些评估可能无法详细反映髋臼结构。本研究旨在通过对三维 CT（CT）图像上的髋臼参数进行检查，根据性别和侧别确定健康土耳其成年人群样本的髋臼形态。回顾性评估了健康土耳其人群样本中因各种原因拍摄的髋臼 CT 扫描。检查参数定义为髋臼前倾角、髋臼外展角、外侧中心边缘角、髋臼宽度、髋臼深度、矢状髋臼角和内侧壁厚度值的测量值。共检查了 126 名患者的 252 个髋关节的 CT 扫描，包括骨骼结构。髋臼指数计算为深度/宽度×100。髋臼指数<20°，内侧壁厚度>5mm 被认为是髋臼发育不良的标准。评估了 73 名女性和 53 名男性的髋臼 CT 扫描，平均年龄为 44.64±12.31（19-68）岁。髋臼前倾角在侧别之间（P=0.007），髋臼深度和髋臼宽度在性别之间（P=0.001，P=0.001）存在统计学差异。整个研究组髋臼发育不良的患病率为 1.6%，男性为 1.9%，女性为 1.4%。在当前的研究样本中，髋臼形态和方位在性别和侧别之间存在参数差异。进一步的更大系列研究将能够更好地代表土耳其人群。
