    The modified Pemberton osteotomy (MPO) aims to reduce the risk of iatrogenic injury to the triradiate cartilage in children with developmental dysplasia of the hip (DDH).

  • 2

    A retrospective review included 55 patients with DDH who underwent MPO, with a mean follow-up duration of 7.21 years.

  • 3

    The mean acetabular index improved significantly from 39.66° preoperatively to 12.71° at final follow-up, indicating effective acetabular remodeling.

  • 4

    According to McKay criteria, 88.7% of hips achieved excellent-good functional outcomes, while the Severin classification showed 93.0% excellent-good joint congruence.

  • 5

    The incidence of avascular necrosis (AVN) was 11.2%, which is considered low and acceptable compared to historical rates for pelvic osteotomies.
