Chronic osteomyelitis of the tibia: treatment with hyperbaric oxygen and autogenous microsurgical muscle...

To establish the success rate of combined therapy for tibial osteomyelitis, we reviewed all cases of this infection treated with surgery, antibiotics, and hyperbaric oxygen (HBO) between 1974 and 1991 at Duke University Medical Center. The median delay from diagnosis of osteomyelitis to initiation of HBO was 12.5 months (range, 1 month to 684 months). Of 34 patients in whom follow-up data were complete, 27 (79%) were male and 7 (21%) female, with a mean age of 37.9 years (range, 20 years to 77 years). Patients received an average of 8.3 surgical procedures (range, 2 to 19) and 35 HBO treatments (range, 6 to 99). Twenty patients (59%) received free vascularized muscle flaps as part of therapy. Actuarial analysis was used to examine the effect of free vascularized flap procedures. Of 26 patients with 24 months of follow-up after treatment, 21 (81%) remained drainage free. At 60 months and 84 months after treatment, 12 of 15 (80%) and 5 of 8 (63%), respectively, were drainage free. After more than 84 months, patients who had received muscle flaps were more likely to be drainage free than patients who had received only debridement, and this difference approached statistical significance.
