Oblique Plane Deformities
The frontal (coronal) and sagittal planes are the standard reference planes. Radiographs that correspond with these planes are AP and lateral X-rays, respectively. If there is an angulation on both frontal and sagittal planes, it means the deformity is on the oblique plane. Deformities other than those on the frontal and sagittal planes are oblique plane deformities. These deformities were previously known as biplanar deformities. However, this description was wrong because they were uniplanar angular deformities in the oblique plane.
