OBJECTIVELittle is known about the optimal duration of antibiotic therapy for diabetic foot osteomyelitis (DFO). This study sought to compare the effectiveness of 6 versus 12 weeks of antibiotic therapy in patients with DFO treated nonsurgically (i.e., antibiotics alone).
RESEARCH DESIGN AND METHODSThis was a prospective randomized trial comparing 6-versus 12-week duration of antibiotic treatment. Remission of osteomyelitis during the monitoring period was defined as complete and persistent (>4 weeks) healing of the wound (if present initially), absence of recurrent infection at the initial site or that of adjacent rays, and no need for surgical bone resection or amputation at the end of a follow-up period of at least 12 months after completion of antibiotic treatment.
RESULTSForty patients followed at five French general hospitals were randomized be-
The results of the present study suggest that, of patients with diabetes with the suspicion of osteomylelitis and a negative percutaneous bone biopsy, only one out of four will develop osteomyelitis within 2 years of the biopsy.
Time to healing and incidence of amputation were comparable with those previously reported for non-removable devices. Given that a removable device is much more acceptable to the patient, the effectiveness, cost and acceptability of the removable devices, such as the Ransart boot, need to be compared with a non-removable device in a randomized trial.
