Innominate osteotomy in the management of residual congenital subluxation of the hip in young adults

The application of innominate osteotomy (IO) to persistent subluxation of the hip in adults is limited. Indeed, a relatively small percentage of such adults, particularly those in the fourth and fifth decades of life, meet the precise indications and essential prerequisites for IO. Nevertheless, in most carefully selected young adults in up to and including the fifth decade of life, IO has proved successful. The objective of IO is to prevent degenerative processes in adults with only potential arthritis, seeking arrest or even reversal of the progression of degenerative disease. IO is applicable only to adults who have arthritis in its earliest stages. Achievement of these objectives is dependent on adherence to the exact indications, prerequisites, and contraindications as well as to the details of the surgical technique as described.
