摘要：
The invention concerns an alignment device for carrying out a periacetabular osteotomy operation on a predefined patient. The device comprises: - a patient-specific acetabular unit, to be fixed in a univocal position on the iliac bone, in proximity of the acetabulum of the femur； - 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. When the acetabular unit and the iliac unit are fixed on the bone, these assume a first mutual position incompatible with the bridge； when osteotomy is carried out and the bridge is connected both to the acetabular unit and to the iliac unit, these assume, the one with respect to the other, 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.
