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

  2. 1999-2006 Experiences after 8 years

  3. Ulf Lillkrona Anders Nordqvist Hans Rahme Björn Salomonsson The Swedish Shoulder and Elbow Society´s, Board of Quality Registers

  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!

  9. REPORTS -2006

  10. COMMON DIAGNOSIS

  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.

  14. 5-YEAR WOOS-SCORE REPLY

  15. 5-YEAR WOOS F.U.

  16. 5-YEAR WOOS REPLY

  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

  26. 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.
