title: [Surgical treatment of fibrous dysplasia in proximal femur].
abstract: OBJECTIVE
  To summarize the oncological and functional results of patients with fibrous dysplasia in the proximal femur and explore its clinical effect.
  
  
  METHODS
  From Apr. 2007 to Jan. 2009, 15 patients with fibrous dysplasia in proximal femur were treated. There were 9 males and 6 females, ranging in age from 16 to 32 years with an average of 25 years. The course of disease was from 2 months to 16 years with an average of 2 years. Among them, 12 cases were unilateral affection and 3 cases were hibateral affections; 12 cases were one bone and 3 cases more than two bones. The collodiaphyseal angles of 2 cases with coxa adducta was 80 degrees and 100 degrees respectively; and femur lengths were shorter than opposite side (5 cm and 3 cm, respectively). The curettage and allogenous and/or autogenous bone-grafting combined with internal fixation were performed in all patients and valgus osteotomies was performed in 2 case with shepherd's crook deformity.
  
  
  RESULTS
  All patients were followed up from 12 to 32 months. Two cases with shepherd's crook deformity, the collodiaphyseal angles recovered after surgery, the relative length of femur was increased 4 cm and 3 cm respectively and they can walk with stick at 4 months after operation. No found recurrence and loosening of internal fixation. Bone graft was absorbed at 3 months and bone healing at 8-12 months after operation. The pain vanished and functions were normal.
  
  
  CONCLUSIONS
  It is an effective method to treat fibrous dysplasia in proximal femur with curettage and bone-grafting combined with internal fixation. Corrective osteotomy and internal fixation with a dynamic hip screw is a good and effective method in treating severe symptomatic shepherd's crook deformity.
