High complication rate after septic orthopaedic implant removal of the lower leg

Reconstruction of septic diaphyseal bone defects with the induced membrane technique

Septic segmental bone voids of the diaphysis are difficult to manage. The induced membrane technique by Masquelet has been successfully used to reconstruct segmental defects more than 20 cm. Our article describes a series of 13 cases with extensive posttraumatic bone loss of the metatarsal, tibial, femoral and radial bones after septic injuries followed by multiple surgical interventions. Antibiotic-impregnated polymethyl methacrylate (PMMA) cement spacers were implanted after successful eradication of bacterial infections of soft tissue and bones. After a mean of 9.8 weeks, body-induced membranes were established and the cements spacers removed. To fill up the bone void, cancellous bone autografts were implanted into the membranes. The follow-up examination after 24 months revealed bony union in all cases and favorable functional results. The induced membrane technique has shown to be effective in treating bone defects of upper and lower extremity bone defects.
