Introduction:
The induced membrane technique (IMT) is a two-stage procedure dedicated to reconstruction of bone defects of the limbs. The aim of this study was to investigate the effect of IMT in the treatment of infected tibial bone defect.
Patients and methods:
A retrospective study was performed among the patients treated using IMT for infected tibial bone defect between 2017 and 2020. The complications were recorded, and the bone defect union and the functional results were evaluated by Paley method. All patients were followed up for at least one year.
Results
We included 12 patients (11 males) with a mean age of 44.5 years (range 19 to 65). The mean length of bone defect was 26.7 mm (range 10 to 60). The mean interval between the stage one and the stage two of the procedure was 11.8 weeks (range 4 to 32). At a mean follow-up of 18.08 months (range 12 to 32), bone union was achieved in all cases in a mean time of 8 months (range 5 to 16) without infection recurrence, where one patient received additional bone grafting. The joint function recovered well for the patients and the rate of functionally excellent and good results was 9/12.
Conclusion
IMT in the treatment of infected tibial bone defect offers the advantages of simple operation, rapid healing of bone defects, and low recurrence rate of infection.
