2. The Swedish Shoulder Arthroplasty Register: Started 1999

3. News 2011 Webbased report function. SITHS card authorisation of user.
New database at RCSyd.
New possibilities for analyse.

4. Purpose:
Analyse the answers from the patients that returned the 1 and 5-year follow-up by WOOS score from 2004 to 2009.
Analys the results by diagnoses concerning the different concepts of arthroplasty (Hemi or Total).

5. 2011 > 8100 primary reports since 1999
> 637 (8 %) were re-operations.
About 1000 reports yearly
covers >90%

6. 2011 WOOS score since 2004: >430 answers, 1-year.

7. Results 2009
Of the 2666 primary reports in the register 1530 answered at 5 year.
57% answered.
20% was dead (or lost address).
23% did not answer.
The 1 and 5 year WOOS from primary procedures was analysed.
