Since its introduction in the late 20th century, the 2-stage induced membrane technique has been lauded for its bone-reconstruction advantages over alternatives such as distraction osteogenesis and vascularized bone. The cases presented in this month’s “Case Connections” demonstrate that the technique can work with a variety of bone-defect shapes, sizes, and locations.
The springboard case, from the August 10, 2016 edition of JBJS Case Connector, describes 3 cases of chronic post-infection osteomyelitis in children in whom large diaphyseal defects were successfully treated with the induced membrane technique. Three additional JBJS Case Connector case reports summarized in the article focus on:
- a 50-year-old diabetic man with a necrotic foot ulcer in whom an extensive midfoot defect was successfully treated with this technique
- successful induced-membrane treatment of a 7-year-old girl with congenital pseudarthrosis of the clavicle
- 2 cases of trauma-caused segmental bone loss that were treated successfully with the induced membrane technique
It is imperative to resolve all active infection before or during stage 1 of this procedure, and careful spacer removal prior to stage 2 is of paramount importance to prevent damage to the induced membrane.
