title: Acetabular reconstruction with human and bovine freeze-dried bone grafts and a reinforcement device.
abstract: BACKGROUND
  This is a cohort trial (1997-2005) of 49 patients submitted to an acetabular component revision of a total hip arthroplasty, using impacted human and bovine freeze-dried cancellous bone grafts (H&FDBG) and a reinforcement device.
  
  
  OBJECTIVE
  To compare clinical/radiographic graft incorporation capability between cancellous bone grafts.
  
  
  METHODS
  There were two groups: I (n=26) receiving human grafts and II (n=25) receiving bovine grafts. The average follow-up times were 55 and 49 months, respectively. Clinical analysis was based on the Merle d'Aubigné and Postel score, and the radiographic analysis involved an established score based on Conn's et al. criteria for radiographic bone incorporation.
  
  
  RESULTS
  No clinical/radiographic differences were found between the groups and both showed an overall rate of 88.5% and 76% of graft incorporation (p=0.424).
  
  
  CONCLUSIONS
  The results presented here are comparable to those in the literature with the use of deep-FG. Therefore, cancellous bone grafts can be safely and adequately used in acetabular component revision in total hip arthroplasty.
