INNOMINATE OSTEOTOMY
First Claim
1. A method of treating a disease of a hip, said hip comprising an ilium having a proximal section and a distal section, an iliac crest, and a subpraacetabular ilium having a medial and a lateral surface, comprising:
- surgically accessing the hip;
making a transverse cut that extends from a first location at the medial surface of the supraacetabular ilium to a second location up to halfway between the medial surface and the lateral surface the supraacetabular ilium;
making an oblique cut extending from the transverse cut towards the iliac crest, such that the oblique cut and the transverse cut define an opening between the proximal section and the distal section;
rotating the distal section of the hip anteriorly, laterally and inferiorly;
obtaining a bone graft;
enlarging the opening defined by the transverse cut and the oblique cut;
inserting the bone graft into the opening defined by the transverse cut and the oblique cut; and
surgically closing access to the hip.

Abstract
This invention provides a surgical method to treat hip diseases, including Legg-Calve-Perthes disease or developmental hip dysplasia. This method includes several surgical techniques: a transverse osteotomy of the posterior portion of supraacetabular portion, an oblique and inclined osteotomy of the anterior portion of the supraacetabulum, detachment of a bone block from iliac crest, anterolateral displacement of the distal fragment, and insertion of the bone block into the distracted space of the osteotomy site.
