Abstract
Background: Triple arthrodesis can be used to correct hind-foot deformities in rheumatoid patients. Postoperative deep infections after triple arthrodesis are challenging to treat often requiring both operative debridement and antimicrobial therapy. The purpose of the present study was to review the treatment of deep infections in the sinus tarsi region in rheumatoid patients after triple arthrodesis using antimicrobial therapy and Papineau bone grafting or local muscle flap. Materials and Methods: Seven rheumatoid patients out of 97 who underwent triple arthrodesis between January 1997 and June 2006 had a deep postoperative infection in the sinus tarsi region. These infections were treated with systemic antibiotic therapy combined with open cancellous bone grafting (Papineau technique) in four cases and with a local muscle flap (adductor digiti minimi) in three cases. Results: The median time from diagnosis of the deep infection to complete healing in six patients averaged 22 weeks, while one patient developed sepsis and died one year later. The most common pathogens were staphylococcus epidermis and staphylococcus aureus; a total of 15 pathogens were found. The average number of revision operations before the infection was considered to have resolved completely was seven. Conclusion: The rate of deep infections was 7.2% among rheumatoid patients. Infections are challenging to treat and cause prolonged morbidity. Surgical debridement and systemic antibiotic therapy combined with Papineau grafting or a local muscle flap usually yielded successful results after postoperative deep infection of the sinus tarsi region in rheumatoid patients.
