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.

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 (n170) but had a higher median
  WOOS score of 73,5 compared to females (n446)
  62.

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.
