Abstract:
The infra-acetabular channel is a channel parallel to the quadrilateral body of the pelvis that passes through the anterior and posterior columns at the medial side of the hip joint. With the widespread use of infra-acetabular channel screws, the acetabular frame screw fixation technique has been proposed to provide stronger fixation for acetabular fractures. There are gender differences in the anatomical parameters of the infra-acetabular channel screws (the length and diameter of the infra-acetabular channel in males are larger than those in females, and the angle between the long axis of the channel and the sagittal plane is smaller). Due to the narrow infra-acetabular channel, it may increase the risks of screw insertion into the hip joint and iatrogenic injury. 3D navigation system-guided placement of infra-acetabular channel screws improves the precision of nail placement. The application of infra-acetabular screws in the fixation of anterior and posterior column fractures has been proved by biomechanical experiments, however, in bicolumnar fractures and T-shaped fractures is still controversial. In order to standardize the placement of infra-acetabular channel screws and to clarify their indications, many studies have been conducted to observe the anatomical parameters of the infra-acetabular channel screws, the surgical technique of placement, biomechanics, and clinical efficacy. This article reviews these studies in order to provide theoretical basis and guidance for the application of infra-acetabular channel screws in acetabular fractures.
