One-Stage Hemi-Plateau Elevating Osteotomy in Advanced Blount’s Disease

Patients presenting with advanced stages of Blount’s disease with medial growth arrest can be treated with a hemi-plateau elevation, usually combined with a metaphyseal valgus osteotomy. We present a case of advanced Langeskiöld VI infantile Blount’s disease in a 9-year-old female. She was treated with a single stage medial hemi-plateau elevation and valgus producing osteotomy and a concurrent lateral tibial plateau and proximal fibular epiphysiodesis. A second metaphyseal osteotomy was not required. She had subsequent contralateral leg epiphysiodesis for leg length inequality concurrent with the removal of hardware. Follow-up showed satisfactory alignment and leg length.
