Purpose

• To analyse the revisions in the register based
  on
• Different diagnoses
• Concepts of arthroplasty.

3
Background

• The Swedish Shoulder Arthroplasty Register
  started in 1999
• Including 2010 we have 8100 surgical procedures
  reported

4
Material

• 7463 Primary procedures were reported 1999-2010
• 637 Revsions and other re-operations were
  reported 1999-2010
• This is 7.9 of the reports

5
Methods

• Of the re-operations reported to the registry,
  more than 230 indexoperations are found in the
  registry.
• These are analysed regarding diagnose and
  procedure.

6
Results RA

• Glenoid problems as a cause of revision.
• For Reumatoid Arthritis
• HSA (n  634) there were 16 revisions (2,5)
• TSA (n  192) there were 2 revisions (1)
• Hemi Shoulder Arthroplasty (HSA)
• Total Shoulder Arthroplasty (TSA)

7
Results OA

• Glenoid problems as a cause of revision.
• For Osteoarthrosis
• HSA (n  1311) there were 36 revisions (2,8)
• TSA (n  852) there were 3 revisions (0,4)
• Hemi Shoulder Arthroplasty (HSA)
• Total Shoulder Arthroplasty (TSA)

8
Results Second. OA / OA

• Survival curves Kaplan-Mayer
• Reoperations after indexoperation 1999-2009

9
Results HSA / TSA

• Survival curves Kaplan-Mayer
• Reoperations after indexoperation 1999-2009

10
Results Fractures

• Cause of revision of implant.
• For Fractures with Hemiarthroplasty (HSA)
• HSA (n  2097)
• Glenoid problems 6 revisions (0,02)
• Instability problem 15 revisions (0,07)
• Infection 10 revisions (0,05)

11
Results Fracture lt2w/gt2w

• Survival curves Kaplan-Mayer
• Reoperations after indexoperation 1999-2009

12
Conclusions

• The numbers are still small and few cases may
  change the results.
• Still there are differences in revision rate
  between different
• Concepts
• Hemi / Total
• Diagnoses
• RA / OA
• Early / Late fracture arthroplasty

13
Conclusions

• Shoulder Arthroplasty is a procedure with good
  long time survival of the implants.
• The register will have better opportunity to
  evaluate the results as the numbers increases
  over time.
