title: [Post irradiation bone lesion of the pelvis (author's transl)].
abstract: Post-irradiation bone lesions of the pelvis, rare but grave functionally, may appear from few months to some years after irradiation. The most severe lesions occur in the hip, with necrosis, fracture or cartilaginous lesions. Radiological appearances may be dissociated, giving a false impression of progression. Undisplaced fractures may consolidate. In other cases an arthroplasty is indicated, often total, but the bad quality of the bone receiving the prosthesis explain certain poor results caused by loosening.
