Abstract
Purpose
To analyze the effectiveness of a vancomycin impregnated calcium sulfate cement bead insertion after debridement (of) an acute-immediate stage infected hip arthroplasty.
Materials and Methods
Between 2002 and 2008, 13 patients with documented acute-immediate stage infection of hip arthroplasty were reviewed and followed for at least two years postoperatively(average 4.3 years). The preoperative and postoperative clinical and radiologic findings and blood laboratory work were checked. All cases were performed through retention of the implant and massive debridement and saline irrigation. After that a vancomycin impregnated calcium sulfate cement beads was inserted.
Results
After the first operation, the average interval for second operation was 27.7 days (17–37). At the second operation, the erythrocyte sediment rate and C-reactive protein were 150.97 mm/hr (34.6 ∼339.7 mm/hr) and 76.4 mg/L (41∼132 mg/L) respectively. Infectious organism were cultured and isolated. There were 5 cases of Methicillin resistant staphylococcus aureus (MRSA). In addition, results of an antibiotics sensitivity test were 8 cases of Vancomycin, and 5 cases of 3rd generation Cephalosporin. Radiologic results showed 10 cases with stable fixation on last follow-up (femoral stem) and 1 case of hip joint space narrowing, acetabular erosion.
Conclusion
Vancomycin impregnated, calcium sulfate, cement bead insertion for an acute immediate infection of hip arthroplasty proved to be a useful method
