II. Pathophysiology

  1. Unilateral congenital abduction contracture of hip
    1. Contracture side of Pelvis tilted downward
  2. Opposite hip acetabulum develops poorly
    1. May result in dysplasia of the acetabulum

III. Signs: Present after 6 weeks of life

  1. Affected Leg appears shorter
  2. Asymmetric gluteal folds

IV. Complications

  1. Dysplasia of the acetabulum
    1. Predisposes to hip subluxation

V. Management

  1. Pavlik harness
    1. Splints hips in flexed and abducted position
  2. Surgical management
    1. Indicated for persistent signs after 8 months of age
