Clinical signs of congenital dislocation of hip in 13 month-old infant. A, Decrease in abduction of right hip with adduction contracture. B, Positive Galeazzi sign with apparent shortening of right lower extremity.

Somerville technique of anterior open reduction in congenital dislocation of hip. A, Bikini incision. B, Division of sartorius and rectus femoris tendons and iliac epiphysis. C, T-shaped incision of capsule. D, Capsulotomy of hip and use of ligamentum teres to find true acetabulum. E, Radial incisions in acetabular labrum and removal of all pulvinar from depth of true acetabulum. F, Reduction and capsulorrhaphy after excision of redundant capsule. G, Developmental dislocation of right hip. H, After anterolateral open reduction. I, At age 7 years; note remodeling of femoral head and acetabulum.

Guidelines for treatment of DDH in relation to age group Neonate: Place in Pavlik harness splint for 6 weeks duration. 1 to 6 months: Place in Pavlik harness for 6 weeks after hip reduces by closed reduction. 6 to 18 months: skin traction; closed reduction. If closed reduction is successful, place in cast for 3 months. If closed reduction is unsuccessful, perform open reduction. 18 to 24 months: Trial of closed reduction, or open reduction. A Salter osteotomy may or may not be part of the procedure. 24 months to 6 years: primary open reduction and femoral shortening, with or without a Salter osteotomy.
