Management of bone defects caused by trauma, osteomyelitis, and tumors is challenging, with many controversies over the optimal reconstruction method. Masquelet discovered induced membrane in management of large diaphyseal defects accidentally, and developed this technique with a concept of induced membrane. Induced membrane technique holds great potential for the reconstruction of bone defects, alternatively to manage this clinical challenge quiet easily. Induced membrane has unique structural characteristics and biological properties, which render this technique has an advantage of the time to bone healing is relatively independent of the length of bone defect. Herein, we reviewed the latest advances made in induced membrane technique and highlighted the concept of induced membrane in the management of bone defects.

The current study was designed to explore the epidemiology of extremities chronic osteomyelitis, its prognosis and the complications of the treatment methods being used in southwest China. The data from osteomyelitis patients treated at the Department of Orthopaedics, Southwest Hospital, China between May 2011 and September 2016 were collected and analysed. The study comprised 503 admitted patients, of which 416 males and 87 were females, with an average age of 40.15 ± 5.64 years. Approximately 356 cases were followed for more than 18 months; the average bone union time was 6.24 ± 0.76 months in 94.1% (335) patients, and infections were almost controlled in 93.8% patients. The rate of infection control with the induced membrane technique was higher than with the I-stage free bone graft. Iliac infection was the main complication of the induced membrane technique, and impaired joint activity was the main complication of I-stage free bone grafts. In southwest China, the incidence of haematogenous osteomyelitis, caused mainly by Staphylococcus aureus, remains very high. The speed of bone defect repair and the rate of infection control with the induced membrane technique were superior to those of I-stage free bone grafts. Internal fixation should be given priority because it offers reduced complications with no increase in the recurrence of infection.
