Review Question - QID 8534

A 13-year-old boy was evaluated for leg length difference. His pelvis balanced when a 1-inch (2.54 cm) block was placed under his left foot. History revealed he had a left distal femur physeal fracture treated with casting at age 10. Radiographs show normal limb alignment, but his left distal femoral physis is closed and his left femur is 2.5 cm shorter than the right. All other physes are open. His bone age is equal to his chronologic age. What surgical treatments will best equalize his discrepancy?
