Objective To investigate the effectiveness of flap combined with induced membrane technique in treatment of post-traumatic tibial osteomyelitis with soft tissue defect. Methods  A clinical data of 33 patients with post-traumatic tibial osteomyelitis with soft tissue defect who met the selection criteria between August 2015 and October 2018 was retrospectively analyzed. There were 21 males and 12 females. The age ranged from 19 to 70 years, with an average of 39 years. The osteomyelitis located in the upper 1/3 of tibia in 8 cases, in the middle 1/3 of tibia in 14 cases, and in the lower 1/3 of tibia in 11 cases. According to Cierny-Mader classification standard, 19 cases of osteomyelitis were type Ⅲ and 14 cases were type Ⅳ. The duration of osteomyelitis ranged from 2 months to 20 years (median, 3 months). In the first-stage operation, after radical debridement, the length of bone defect was 1.5-12.5 cm (mean, 5.0 cm) and the size of soft tissue defects ranged from 5 cm×4 cm to 15 cm×12 cm. Bone cement containing antibiotics was implanted into the bone defect and the personalized flap was used to repair the wound. After the wound healed at 6-8 weeks and the infection was controlled, bone grafting was performed to repair bone defects in the second-stage operation. Results  The flaps survived completely after the first-stage operation in 29 cases. Partial necrosis of the flap occurred in 4 cases and healed after surgical dressing change. All the incisions healed by first intention after the second-stage operation. All patients were followed up 24-32 months (mean, 28 months). All the bone grafts healed after operation, and the radiographic healing time was 3-9 months (mean, 5 months). The clinical healing time was 4-14 months (mean, 8 months). There was no recurrence of osteomyelitis during follow-up. At last follow-up, according to Johner-Wruhs evaluation criteria, the limb function was excellent in 27 cases, good in 4 cases, and fair in 2 cases, with an excellent and good rate of 93.9%. Conclusion  For the post-traumatic tibial osteomyelitis with soft tissue defect, the flap combined with induced membrane technique is a reliable and effective method and can effectively restore the function of lower limbs with satisfactory effectiveness.
