Septopal Beads and Autogenous Bone Grafting for Bone Defects in Patients With Chronic Osteomyelitis

Thirty-five patients with chronic osteomyelitis were treated with autogenous bone grafts for bone defects. Of 35 patients, two were lost to follow-up evaluation. There were 27 men and six women. The age range was from 18 to 62 years (median age, 29 years). The bones included 22 tibias, nine femurs, and two ulnas. The size of the bone defects ranged from 2.5 x 15 cm (median defect, 2.5 x 6 cm). The length of infection ranged from two to 540 months (median, 31 months). Twenty patients had nonunions and 19 patients required soft-tissue muscle transfers. Patients were treated with systemic antibiotics and/or gentamicin (Septopal) antibiotic beads. Twelve patients were treated with Septopal beads. The range of follow-up evaluation was 24 to 68 months (median, 47 months). Thirty-one of 33 patients had one bone-graft procedure and two patients required two. The time from initial debridement and infection control to bone graft for patients not requiring soft-tissue muscle flaps was one to six weeks (median time, four weeks). For patients requiring soft-tissue muscle transfer, the range was six to nine weeks (median, six weeks). The median time to bone-graft incorporation was six months. All fractures united. Complications included two refractures from auto accidents in the immediate postoperative period, one partial muscle loss, one skin-graft loss, four pin tract draining sites, and two antibiotic-related skin rashes. There was one recurrent infection, and the infection arrest rate was 97%.(ABSTRACT TRUNCATED AT 250 WORDS)
