Abstract
Despite numerous advances in the management of chronic osteomyelitis, many questions remain. To date, no evidence-based guidelines exist in the treatment of chronic osteomyelitis. In essence the aim is to improve quality of life through either a curative or a palliative treatment strategy. The choice of treatment strategy is based on the physiological status of the host. This process of host stratification is, however, complicated by the fact that the definition of a C-host has never been standardized.
Purpose;
The aim of the study was to investigate the short term outcome of the treatment of chronic osteomyelitis in adult patients where selection of a management strategy was based on a refined host stratification system.
Methods;
A retrospective review was performed of adult patients with chronic osteomyelitis seen over a one year period. In total 116 patients were included in the study. A modified host stratification system was applied, incorporating predefined major and minor criteria, to determine each patient's host status.
Results;
A high prevalence of HIV infection (28.6%) and malnutrition (15%) was present in the study population. Almost half the patients were classified as C-hosts (44.8% or n=52), followed by B-host classification in 39.7% of cases (n=46). At a mean follow-up of one year an overall success rate of 91.4% (95% CI: 84.7–95.8%) was achieved. Host status and outcome (remission, suppression or failure) was significantly dependent (p-value < 0.001). Success was achieved in 92.2% of patients treated curatively and 89.6% of patients treated palliatively.
Conclusion;
By integrating the physiological status of the host (based on objective predefined criteria) with the appropriate curative, palliative or alternative treatment strategy we were able to achieve acceptable outcomes in both low and high risk cases and, in addition, avoid unnecessary amputation.
