Abstract

BACKGROUND

The anatomy of the posterior wall of the acetabulum is important for the hip stability. We wanted to know whether differences can be observed.

MATERIAL AND METHODS

On lateral 3D pelvic CT reconstruction of the pelvis two types were identified. On axial CT-images acetabular angles were determined.

RESULTS

We observed 35 type I acetabular and 61 type II acetabular. Posterior acetabular sector angle was 114° in type I and 94° in type II acetabular (p < 0.01). At an cut-off angle of 100° we could predict the type of acetabulum.

CONCLUSIONS

We could describe reference values for the posterior wall to distinguish two morphological types.

摘要

背景

髋臼后壁的解剖结构对髋关节稳定性很重要。我们想知道是否能观察到差异。

材料与方法

在骨盆的外侧三维骨盆CT重建图像上识别出两种类型。在轴向CT图像上确定髋臼角。

结果

我们观察到35例I型髋臼和61例II型髋臼。I型髋臼的髋臼后扇区角为114°，II型髋臼为94°（p < 0.01）。以100°为临界角，我们可以预测髋臼类型。

结论

我们可以描述后壁的参考值以区分两种形态类型。
