Standing antero-posterior radiograph of the pelvis and hips of a 28-year-old patient with McCune–Albright syndrome and monomelic right fibrous dysplasia involvement done at follow-up 8 years after her right femur intramedullary nailing. A 4.5 cm hip height discrepancy was present, which had increased by 3 cm during the last 4 years due to a protrusion of her left hemi-pelvis into the pelvic ring. She had a painful limp, a 3 cm shoe lift, and she used 2 crutches for walking. A poor result was obtained, with a clinical Jung score of 4 points
