Review Question - QID 214674

A 12-year-old presents with difficulty with running and experiences frequent falls from tripping over his toes. He states his right foot is mostly affected. He saw an orthopedic surgeon for this at the age of 4 years but was told this would likely resolve with time. On exam, the right foot appears to be pointing outward relative to the contralateral foot with gait. Select CT images are depicted in figures A-D. Figure E is a table depicting angular measurements. Which treatment option will most reliably correct the underlying problem?
