St George J, Kulkarni V, Bellemore M, et al. - Researchers conducted this case‐matched control study to quantify the treatment required and compare the 5‐year radiological outcomes between early and late diagnosis in children with developmental dysplasia of the hip (DDH) with frank dislocation. From 2000 to 2010, children with frank DDH dislocations comparing three groups: children with an early diagnosis successfully treated in a Pavlik harness, children with an early diagnosis who failed Pavlik harness treatment and children with a late diagnosis (LD). In total, 115 hips were involved. LD group patients needed significantly more open reductions, acetabular osteotomies, and femoral osteotomies. High rates of LD in DDH persist in Australia in the context of selective ultrasound screening. Although good radiological results can be obtained, a significantly higher level of surgical intervention is needed, and this is associated with significantly higher growth disturbance rates. Screening optimization in Australia is vital.
