4. THE REGISTER It is owned by SSAS. Will change plattform to get an internet report solution. Cooperation with the NKO.

5. REGISTER AIM: Earlier identification of problems. Obtain results for:  Designe  Technique  Diagnose

6. REPORTS Simple, 2 minutes. (Internet in 2007) 5-year follow-up by mail. WOOS, EQ-5D.

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

8. PROBLEMS Missing information <5% Missing reports <10%  Trauma-surgeons?  Local organisation!  Uncertain comparison! 2 Hospitals do not report!

11. The Swedish Shoulder Arthroplasty Register. 1999-2006 5year follow-up by WOOS- score in 616 primary shoulder arthroplasties.

12. 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.

13. 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.

17. 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.

18. 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%.

19. 5-YEAR WOOS GENDER

20. 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%

21. 5 YEAR WOOS DIAGNOSE

22. RESULTS: Comparing different concepts by the median WOOS score: Hemi arthroplasty (n=516, WOOS 64%) Total arthroplasty (n=75, WOOS 81%)

23. 5 YEAR WOOS HEMI / TOTAL

24. 5-YEARS SATISFACTION One question on patient satisfaction after 5 years was also asked.

25. 5-YEARS SATISFACTION

27. 5-YEARS WOOS/HOSPITAL

28. 5-YEARS WOOS/IMPLANT

29. IMPLANTS A majority of the implants used at the beginning 1999 now is out of market or has a changed design 2007.

30. 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.

31. 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.
