Arthroplasty infection rates in fractured neck of femur: single vs dual antibiotic cement
Savage P, McCormick M, Al-Dadah O Ann R Coll Surg Engl 2019; 101: 514–518.
At a Glance
No deep surgical site infections (SSI) were observed when prostheses had been cemented with COPAL® G+C vs. 2.8% deep SSI when prostheses were fixed with low-dose single antibiotic-loaded bone cement (SALBC) at 12 months of follow-up
Superficial SSI rate of 5.1% in the COPAL® G+C group vs. 3.7% in the SALBC group at 12 months of follow-up
Study details
Retrospective and prospective analysis of 206 patients with cemented (hemi-)arthroplasty after fractured neck of femur (FNOF)
Comparison of prothesis fixation with high-dose dual antibiotic-loaded bone cement (DALBC) COPAL® G+C vs. SALBC
Endpoints: deep and superficial SSI within 12 months following surgery
Location
South Tyneside District Hospital, United Kingdom
Endpoints
Rate of deep and superficial SSI
Similar patient characteristics in both study groups
Clinically* significant reduction of deep SSI over 12 months when prostheses were fixed with COPAL® G+C vs. SALBC
All 3 deep SSI were observed in the group of patients who had undergone cemented hemiarthroplasty with SALBC whereas more superficial and easier to treat SSI were observed in the COPAL® G+C group
Microbiology culture results from patients with deep SSI showed growth of S. aureus, with no bacterial growth and coliforms
* The cohort considered was too small, which is why no statistical significance could be calculated, nevertheless the authors identified a clinical significance.
