Why the study?
What are the clinical and radiological outcomes of surgical treatment for subluxation of the hip presenting for the first time in children over the age of four years?
What are the clinical and radiological outcomes of surgical treatment for subluxation of the hip presenting for the first time in children over the age of four years?
Surgical treatment of late-presenting hip subluxation in children over four yields good clinical outcomes, though radiological abnormalities like avascular necrosis may persist.
May support surgical correction for late hip subluxation; leaves open long-term implications of radiological changes.
Subluxation of the hip presenting for the first time in a child over the age of four years is rare. We report ten cases treated over nearly 11 years by the senior author (JAF). We describe the surgical procedures and the results, at maturity, of nine of the ten patients. At a mean follow-up of nearly nine years, the clinical outcome was good in all ten children by the criteria of Ponseti. Radiological assessment showed that three hips remained subluxed, and that four had avascular necrosis of the physis. We advise a one-stage procedure, correcting both the femur and acetabulum.
