Periacetabular Osteotomy for Mild or Borderline Acetabular Dysplasia

Evaluating the adolescent and young adult hip can be challenging given the rapid evolutions in the field over the last 10-20 years. One of the more difficult groups of patients to evaluate are those that fall into the mild or borderline acetabular dysplasia. We must determine whether the patient's pain and chondrolabral disease is due to their acetabular morphoplogy or their associated femoral morphology and therefore is more of an unstable or an impingement hip. A thorough history, physical examination, and imaging evaluation are needed to determine the best treatment option in these patients. When this evaluation determines that the patient is suffering from a primary instability problem, these patients are best treated with a surgery that improves the stability of the hip. Here we describe the patient evaluation and periacetabular osteotomy technique in the mild or borderline dysplastic patient.
