Supramalleolar Dome Osteotomy for Malunion of the Tibia

A 31 year old healthy female was involved in a motor vehicle accident (MVA) in 2002 resulting in a distal tibia fracture. The follow-up X-rays showed a distal tibia valgus deformity that was interpreted as a post-traumatic tibial malunion. The patient started with pain at the ankle approximately 10 years after the accident. A supramalleolar osteotomy (SMO) was offered to the patient to correct the deformity. It was performed with internal and external fixation achieving an aligned extremity and a good clinical outcome.
