title: [Prosthetic hip revision: relationship between bone stock and quality of life in aseptic loosening of the femoral component].
abstract: OBJECTIVE
  We evaluated the clinical and radiographic results in the medium and long term in patients undergoing revision surgery for aseptic loosening with different bone quality at the time of the operation. We investigated how different bone quality shapes for a good clinical result.
  
  
  METHODS
  A total of 33 patients who underwent revision surgery of the hip (for aseptic loosening of the stem) evaluated radiographically and clinically at 1,6,12 and 18 months. The evaluation of clinical status preoperatively and at the end of follow-up was be made as questionnaires SF-36, Harris Hip Score and WOMAC; radiographic assessment was made using the scale of Paprosky. The data thus obtained have been related to complications arising and the status of femoral bone-loss before the surgery time.
  
  
  RESULTS
  The groups PI and PII (Paprosky) showed a high level of satisfaction with an average value of reference for the postoperative rated as excellent, the absence of complications and good functional recovery at the end of follow-up. The groups PIII and PIV showed increased incidence of complications and difficulties with rehabilitation clinics and SF-36 scores and HHS inferior to other classes.
  
  
  CONCLUSIONS
  Our dates confirm that bone quality at the time of surgery affects the therapeutic target. All patients with good bone quality at the time of the revision surgery (groups PI and PII) showed a distinct advantage from surgical treatment. Revision surgery had not much effect in patients with high bone loss. Preservation of bone stock should be considered a good foundation for the success of a prosthetic reimplantation with better functional and radiographic out-come associated with greater satisfaction for the patient.
