An example of Type C femoral overgrowth in a 16-year-old girl (Patient 16). a At age seven years, the patient, exhibiting 14 mm of femoral overgrowth of the affected limb, had failed to achieve union of the tibia via bone transport using the Ilizarov method and was referred to our institution. b After the patient underwent distraction osteogenesis, the femoral overgrowth resolved. c No significant femoral overgrowth was evident after the patient reached skeletal maturity. d The pattern of femoral overgrowth did not correlate with any of the subtypes defined by Shapiro’s classification [16]. The white diamond indicates the point at which the patient underwent distraction osteogenesis
