ABSTRACT
Objective:
Evaluating the clinical results of bioactive glass S53P4 putty for the treatment of cavitary chronic osteomyelitis.
Methods:
Retrospective observational study, including patients of any age with clinical and radiological diagnosis of chronic osteomyelitis, who underwent surgical debridement and implantation of bioactive glass S53P4 putty (BonAlive® Putty, Turku, Finland). Patients who underwent any plastic surgery on the soft tissues of the affected site or had segmental bone lesions or septic arthritis were excluded. Statistical analysis was performed using Excel®. Demographic data, as well as data on the lesion, treatment, and follow-up, were collected. Outcomes were classified as “disease-free survival,” “failure,” or “indefinite.”
Results:
This study included 31 patients, of which 71% were men and had with a mean age of 53.6 years (SD ± 24.2). In total, 84% were followed-up for at least 12 months and 67.7% had comorbidities. We prescribed combination antibiotic therapy for 64.5% of patients. In 47.1%, Staphylococcus aureus was isolated. Finally, we classified 90.3% of cases as “disease-free survival” and 9.7% as “indefinite.”
Conclusion:
Bioactive glass S53P4 putty is safe and effective to treat cavitary chronic osteomyelitis, including infections by resistant pathogens, such as methicillin-resistant S. aureus. Level of Evidence IV, Case Series.
