Background: fibrous dysplasia is characterized by the formation of fibrous tissue that generates immature malformed trabeculae. Their involvement may be monostotic or poliostotic. Case report: Thirty years old female with fibrous dysplasia of the left hip. At age 15 suffered hip fracture without apparent trauma, she was managed conservatively and significant shortening of the same limb was observed. At 30 years old, is pregnant, it had left hip pain, deformity and shortening is exacerbated. Simple radiography showed «shepherd’s crook deformity», she was treated with bisphosphonates. Computed axial tomography corroborates previous findings. She subsequently underwent subtrochanteric fracture fall with left hip dysplasia site, ground glass image of cystic appearance involving the femoral neck, trochanteric and subtrochanteric area. Tumor prosthesis of the left hip was implanted, four months evolution was favorable. Conclusion: Modular hip prosthesis system, reduces deformity, improves length and reduces pain in patients with resection of fibrous dysplasia of the hip.

Key words: Fibrous dysplasia, femur, tumor prosthesis, monostotic, poliostotic.
