Abstract

LARA-VILLCA, Renan  and  UNDURRAGA-CARMONA, Norberto. Membrane technique induced in the reconstruction of postraumatics bone defects. Gac Med Bol [online]. 2018, vol.41, n.2, pp.18-20. ISSN 1012-2966.

The Induced Membrane Technique or Masquelet is a surgical procedure used to treat pseudoarthrosis, diffuse osteomyelitis with great kidnappings and bone defects. Objectives: to evaluate the results obtained with the Induced Membrane Technique in the surgical treatment of post-traumatic bone defects. Methods: descriptive, longitudinal study, case series type: reported five cases of post-traumatic bone defects treated at Viedma Clinical Hospital, since January 2016 to December 2017, through two-stage reconstruction. In the first, membrane formation was induced with a bone cement spacer impregnated with antibiotic. In the second, the spacer was replaced by bone graft. The consolidation time, functional result and complications were recorded. Results: Five patients were included (four men and one woman), with an average age of 31 years (range: 16-54). Two cases were in the tibia, one case in the femur, one in the talus and one in the ulna. Three of the bone defects were in length greater than or equal to 50 mm, with an average of 64 mm; three of the cases had positive cultures at the start of treatment and four presented consolidation, with a single contribution of bone graft. The average time for consolidation was eight months. One case presented persistence of infection. Conclusions:  It represents a good alternative in the management of segmental bone defects, with adequate consolidation rates, low complications, tolerable by the patient and reproducible in hospitals in our environment.
