Total Hip Arthroplasty Requiring Subtrochanteric Osteotomy for Developmental Hip Dysplasia

Abstract This study evaluated total hip arthroplasty in patients with developmental hip dysplasia requiring femoral subtrochanteric shortening derotational osteotomy (SDO). Twenty-three total hip arthroplasties that required SDO were evaluated at an average follow-up of 8 years (range, 5-14 years)....

Summary:Abstract This study evaluated total hip arthroplasty in patients with developmental hip dysplasia requiring femoral subtrochanteric shortening derotational osteotomy (SDO). Twenty-three total hip arthroplasties that required SDO were evaluated at an average follow-up of 8 years (range, 5-14 years). Clinical and radiographic data were retrospectively reviewed. Four hips (17%) failed requiring revision. Time to revision averaged 4 years (range, 1-8 years) with polyethylene wear and osteolysis etiologic in 3 of 4 failures. Survivorship was 75% at 14 years. Subtrochanteric SDO provided reliable correction of dysplastic femoral deformity, facilitated hip reduction at the anatomic center, and demonstrated predictable union in all cases. Wear-induced osteolysis was the major reason for revision, probably due to the relatively thin polyethylene liners required for the small acetabular components used in young, active patients.
