Alignment device for acetabular osteotomy

摘要

The present invention relates to an alignment device for performing acetabular osteotomy surgery on a given patient. The device is a patient-specific iliac unit that is fixed in a unique position on the ilium near the ostomy of the femoral bone and on the ilium in a lateral position with respect to the iliac unit. It comprises a patient-specific iliac unit that is fixed in a unique position and a patient-specific bridge that is firmly and uniquely connected to the ostomy and iliac unit. If the acetabular and iliac units are anchored to the bone, they take a first reciprocal position that is incompatible with the bridge and an osteotomy is performed and the bridge is of the acetabular and iliac units. When connected to both, they are in a second position, one with respect to the other, which is different from the first position and corresponds to the biodynamically correct position of the acetabulum with respect to the rest of the acetabulum.
