title: Treatment of infected segmental defect of long bone with vascularized bone transfer.
abstract: Experience with infected pseudarthrosis with segmental osseous defect, treated by debridement and microvascular bone transfer, is reported. Fourteen patients form the basis for the study, including 12 males and two females. Patient age at the time of operation averaged 35.1 years. Follow-up averaged 52 months. The affected site included tibia (10), femur (2), and ulna (2). A total of 15 vascularized bone graft transfers were carried out for the 14 patients, with the donor bone fibula (8) and ilium (7). Bony union was ultimately obtained in all patients. In 11 patients, primary union was obtained at both ends of the transferred bone segment. In the remaining three patients, a secondary procedure, consisting of onlay nonvascularized bone autografting at one end of the vascularized transferred bone segment, was required to obtain union. Recurrent infection following union occurred in one patient. One of the two patients with active osteomyelitis at the time of vascularized bone transfer had complications from recurrent sepsis, leading to the authors' caveat that vascularized bone transfer should be deferred until such time as sepsis is inactive. Criteria used in this series for determining inactive sepsis (absence of sinus tracts, negative bacterial cultures, negative c-reactive protein, and a sedimentation rate of less than 15 mm per hour) seem appropriate. The study suggests that vascularized bone transfer is a useful procedure for the treatment of infected segmental osseous defects of long bones, of more than 3 cm extent and one month or more after inactive sepsis.
