Case 65: Hemiplateau Elevation for Early-Onset Blount Disease

Abstract

This is a 5 year old female with left-sided genu varum with radiographs consistent with early-onset Blount disease. The patient underwent a proximal tibial osteotomy but subsequently had a recurrence of her deformity with marked clinical genu varum. Subsequently, a CT scan and MRI were obtained that demonstrated a posteromedial bar. The patient was indicated for a proximal medial tibial hemiplateau elevation as well as a proximal lateral tibial drill epiphysiodesis and a proximal fibula drill epiphysiodesis. Postoperatively, the patient did well with the restoration of her mechanical alignment. Several years later, the patient required a contralateral tibial epiphysiodesis to prevent future leg length discrepancy.
