[Dislocation and necrosis of the first, second and third wedges. Management with the Masquelet technique. A case report]. / Luxación y necrosis de la primera, segunda y tercera cuña, manejo con técnica de Masquelet. Reporte de un caso.

The induced membrane technique was first described by Masquelet in 1986. It was initially used for the reconstruction of long bone shaft defects, particularly of the femur and tibia. The technique consists of two stages. During the first stage a membrane is induced to provide support to the grafts and supply growth factors that contribute to provide a favorable receiving bed for the future graft. During the second stage the poly-methyl-methacrylate spacer is removed and replaced with bone grafts, usually harvested from the iliac crest. Given that this technique has proven good results, it started to be used at other bone sites. We present herein the case of a patient with a large bone defect in the midfoot in whom the Masquelet technique was used with iliac crest grafts. Arthrodesis with a distal radius plate was performed to improve medial column stability, with favorable clinical and functional results.
