Anteroposterior pelvis radiograph showed severe osteolytic involvement of the hips associated with massive disorganization/distortion of the weight bearing components with subsequent development of lower limb length inequality. The patient was able to walk a few days after surgery using crutches with partial weight bearing. Osteogenesis imperfecta was the first proposed diagnosis because of long bone fracture and osteopenia. Next-generation sequencing panel to detect COL1A1/2 mutations was negative.
