[Repairing tibial post-traumatic osteomyelitis with bone and skin defect by Ilizarov technique at stage I].

Objective: To explore clinical effects of Ilizarov technique at stage I for repairing tibial post-traumatic osteomyelitis with bone and skin defect.

Methods: From June 2010 to December 2013,44 patients with tibial post-traumatic osteomyelitis with bone and skin defect were treated with Ilizarov technique at stage I . Among them, there were 35 males and 9 females aged from 18 to 70 years old with an average of 42.5 years old. Bone defect ranged from 4 to 16 cm, skin defect ranged from 3 cm x 4 cm to 5 cm x 16 cm. The operation was performed debridement thoroughly, removed inflammatory bone section, osteotomy invasively, install circular external fixator by Ilizarow technique; screw nut were rotated at 1 week after operation, and prolonged 0.5 to 1.0 mm everyday. Wound surface, new born callus and bone healing were observed to evaluate clinical effects.

Results: All patients were followed up from 11 to 36 months with an average of 18.5 months. Bone defect after osteotomy was from 6 to 22 cm with an average of 11.5 cm; the time of wound healing time ranged from 21 to 79 d with an average of 38 d; bone defect healing time was from 8 to 15 months with an average of 12.5 months. All patients were cured, no recurrent infection, refracture and shorten of calf deformity were occurred.

Conclusion: Repairing tibial post-traumatic osteomyelitis with bone and skin defect by llizarov technique at stage I has advantages of less trauma, low inflammatory recurrence rate, could avoid multiple complex operation, and receive definite curative effect.
