  • Well documented.
  • Diagnose-specific.
  • Patient self-evaluating.
  • Validation in Swedish.
  • The same score in Denmark.

The Swedish Shoulder Arthroplasty Register.1999-2006

5year follow-up by WOOS-score in 616 primary shoulder arthroplasties.

slide12
AIM:
  • To examine the functional outcome of primary shoulder arthroplasties that were reported to the Swedish National Registry.
  • This was conducted as a self evaluation with a WOOS-score.
  • 5 years after surgery.
material
MATERIAL:
  • All patients with a report of a shoulder arthroplasty to the Swedish National Registry is asked to complete a WOOS score 5 years after the reported surgery.
  • The registry started in 1999, and until 2001, 1238 primary shoulder arthroplasties were reported.
5 year woos score
5 YEAR WOOS-SCORE
  • 616 patients from 42 different hospitals completed the mailed WOOS-score and returned it to the register by mail during 2004-2006.
  • The WOOS score i presented as a percentage of a normal shoulder function.
results
RESULTS:
  • The WOOS score was calculated for different patient selections.
  • Males were fewer (n=170) but had a higher median WOOS score of 73,5% compared to females (n=446) 62%.
results20
RESULTS:
  • Nonunion n=15, WOOS 38%
  • Osteonekrosis n=20, WOOS 53,5%
  • Cuff arthropaty n=24, WOOS 57,5%
  • Reumatoid arthritis n=146, WOOS 62%
  • Fractures n=197, WOOS 65%
  • Secondary arthrosis n=31, WOOS 66%
  • Osteoarthrosis n=141, WOOS 79%
results22
RESULTS:
  • Comparing different concepts by the median WOOS score:
  • Hemi arthroplasty

(n=516, WOOS 64%)

  • Total arthroplasty

(n=75, WOOS 81%)

5 years satisfaction
5-YEARS SATISFACTION

One question on patient satisfaction after 5 years was also asked.

implants
IMPLANTS
  • A majority of the implants used at the beginning 1999 now is out of market or has a changed design 2007.
conclusion
CONCLUSION:
  • The Swedish Shoulder Arthroplasty Register now is beginning to produce results from a 5 year follow-up.
  • The follow-up rate of 50% is not yet enough, but the results will still be able to give an indication of what result to expect from a shoulder arthroplasty in different patient selections.
further analysis
FURTHER ANALYSIS:
  • Analysis will also be made between different implants and hospitals in the next years.
  • Change in design of the implants will result in new entities for the analysis.
