摘要： Various implementations include an alignment device for carrying out a periacetabular osteotomy operation on a patient that includes
a patient-specific acetabular unit, to be fixed in a univocal position on the iliac bone, in proximity of the acetabulum;
a patient-specific iliac unit, to be fixed in a univocal position on the iliac bone, in a lateral position with respect to the acetabular unit; and
a patient-specific bridge, to be connected in a rigid and univocal manner to the acetabular unit and to the iliac unit.
The acetabular unit and the iliac unit assume a first mutual position incompatible with the bridge. When osteotomy is carried out and the bridge is connected to the acetabular unit and the iliac unit, they assume a second position, different from the first position and corresponding to a bio-mechanically correct position of the acetabulum with respect to the remaining portion of the iliac bone.-
