Staged protocol for the treatment of chronic tibial shaft osteomyelitis with Ilizarov's technique followed by the application of intramedullary locked nail.

Open tibial shaft fractures are the most common open fractures, and many complications can occur. During the treatment period, infection leading to osteomyelitis was the most common complication. However, no consensus exists regarding the ideal management for such cases in the literature.The purposes of this retrospective study were to review the treatment of patients with chronic tibial shaft osteomyelitis over the past 14 years who were referred to the authors' institution and to provide a staged protocol for spontaneous wound healing. The staged protocol included: (1) radical debridement for infected bone and soft tissue; (2) immediate application of Ilizarov's apparatus for all patients except those needing delayed application; (3) osteotomy in healthy bone; (4) simultaneous distraction-compression osteogenesis and histogenesis; (5) additional docking-site bone grafting; and (6) shifting the external fixator to a locked nail when callus formation was visible at the distraction site. Union was achieved in 15 of 16 patients, with an average external fixation time of 4.5 months (range, 3-6 months). No deformity or leg-length discrepancy greater than 1 cm occurred.In the treatment of chronic osteomyelitis, this staged protocol was safe and successful and allowed for union, realignment, reorientation, and leg-length restoration. Regarding the soft tissues, this technique provides a unique type of reconstructive closure for infected wounds. It is suggested that the staged protocol is reliable in providing successful simultaneous reconstruction for bone and soft tissue defects without flap coverage.
