Early detection with Barlow/Ortolani; ultrasound (Graf) guides treatment under 6 months. Pavlik harness is first‑line for reducible dislocation under ~6 months; avoid excessive extension/abduction to reduce AVN risk. Failed Pavlik → closed reduction and spica; if unstable/obstructed, open reduction with capsulorrhaphy and femoral shortening/derotation as needed. Residual acetabular dysplasia treated with pelvic osteotomies (Salter, Pemberton, Dega) based on age and pathology. Complications: AVN (Kalamchi‑MacEwen), redislocation, stiffness, femoral nerve palsy with Pavlik.
