Reimer's migration index can be used to indicate hip dislocation. The migration index (MI) is normally less than 33%. An anterior-posterior (AP) X-ray of the pelvis and a cross-table lateral X-ray of the effected hip are ordered for diagnosis. The size of the head of the femur is then compared across both sides of the pelvis. The affected femoral head will appear larger if the dislocation is anterior, and smaller if posterior. A CT scan may also be ordered to clarify the fracture pattern. Dislocation of the left hip, secondary to developmental hip dysplasia. Closed arrow marks the acetabulum, open arrow the femoral head.
