Open reduction,Dega osteotomy and proximal femoral osteotomy in delayed diagnosis of developmental hip dislocation: outcome at 40-year follow-up

PurposeLate-diagnosed dislocated hips underwent open reduction, Dega osteotomy, and proximal femoral osteotomy between 1968 and 1988. The objectives of this study are to assess the survival of hips into adulthood, clinical and radiological outcome, patients’ life perspectives and the risk factors of failure.MethodsAn assessment of 67 hips treated when younger than five years (ResultsThe 40-year survival rates were 73% (95% confidence (CI) 71% to 76%) in the ConclusionEarly failure risk factors are older age at the surgical procedure, high AVN grade and bilateral hip involvement. Still, the results facilitate hip reposition whenever technically manageable, even in teenagers.Level of evidenceIII
