Transgluteal posterior column screw stabilization for fractures of the acetabulum: a technical trick

The traditional exposure of high posterior column or transverse acetabular fractures can pose a challenge for lag screw stabilization. The authors describe an adjunctive percutaneous transgluteal lag screw technique for the internal fixation of the high posterior column. In the senior author's experience, this technique has been helpful to achieve the optimal trajectory for a stable perpendicular lag screw to maintain an anatomical reduction. In our experience, this technique has been used in conjunction with the standard Kocher-Langenbeck exposure and posterior column plating techniques.
