[Paget's disease and surgery].

Paget's disease may in some cases require recourse to surgery: (1) Fractures of bones in patients with the disease mend normally but slowly. Orthopaedic treatment is satisfactory, except for the femur where osteosynthesis is necessary. (2) Severe deformation of the lower limbs should be corrected by osteotomy when it is responsible for serious disablement. With a simple and sure technique functional improvement can be assured. (3) Coxopathy associated with Paget's disease sometimes involves sufficient invalidity to justify total arthroplasty. (4) Malignant degeneration, usually determined by biopsy, is beyond any therapeutic treatment.
