Summary
Deep periprosthetic infections after shoulder arthroplasty are a concern. This study found no difference in infection rates between anatomic TSA (aTSA) and reverse TSA (rTSA) in primary cases without prior surgery. However, prior nonarthroplasty operations increased infection risk, particularly with rTSA.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Infectious Disease
Background:
- Deep periprosthetic infection is a significant complication following total shoulder arthroplasty (TSA).
- Suboptimal clinical outcomes are associated with these infections.
- This study compares infection rates between primary anatomic TSA (aTSA) and reverse TSA (rTSA).
Purpose of the Study:
- To determine if infection rates differ between primary aTSA and rTSA.
- To investigate the impact of previous nonarthroplasty operations on infection risk in TSA.
- To identify risk factors for deep periprosthetic infection after primary shoulder arthroplasty.
Main Methods:
- Retrospective review of a TSA database (2004-2012).
- Identification of primary TSAs with confirmed deep periprosthetic infections.
- Data collection included patient demographics, diagnosis, prior operative history, implant type, and organism.
Main Results:
- 16 deep periprosthetic infections occurred in 814 primary TSAs (6 aTSA, 10 rTSA).
- No significant difference in infection rates between aTSA and rTSA in shoulders without prior surgery.
- Shoulders with prior nonarthroplasty operations had a significantly higher infection rate (P = .016), especially with rTSA.
Conclusions:
- Primary aTSA and rTSA have similar infection rates in shoulders without prior surgery.
- Previous nonarthroplasty operations increase the likelihood of deep infection after primary TSA.
- rTSA in previously operated shoulders shows a notably higher infection risk.
