The author has found valuable a method of pelvic-support osteotomy, in which, by using a locking subtrochanteric osteotomy and displacing the lesser trochanter into the acetabulum, he has secured good stability and freedom from pain, as well as an adequate range of motion, in cases of irreducible congenital dislocation of the hip. The procedure is indicated in cases of supracotyloid position, but can also be employed in high iliac dislocations after preliminary skeletal traction.
Eighteen patients have been treated by this method, of whom four had bilateral dislocations.
The end results, in the author's experience, are much better than those obtained by other methods.
