Challenges of the induced-membrane technique in the reconstruction of traumatic tibial defect with limited resources : a cohort study

Acta Orthop Belg. 2020 Dec;86(4):606-613.

Abstract

This study sought foremost to evaluate the outcomes of applying the induced membrane technique (IMT) for tibia reconstruction within the context of a sub-Saharan Africa trauma center. Second, this study aimed to elucidate the conditions of IMT usage in a limited-resource setting. A retrospective study was performed among patients treated via IMT for posttraumatic tibial bone defects who had follow-up data available for at least 12 months. Eleven patients with a mean age of 36 years were included. All presented with an infected multi-tissue defect. The mean length of the tibia defect was 4.4 cm and the mean area of the soft-tissue loss was 32 cm2 . Pedicled flap coverage was required in all cases. At the mean follow-up time of 15 months bone union was achieved in nine of 11 cases, after additional inter-tibiofibular grafting was performed in four cases. Infection recurrence was noted in five of 11 cases. Most patients presented medium-quality soft-tissue coverage and suboptimal function. IMT may represent a valuable option for tibia reconstruction with limited surgical resources in cases where appropriate infection control and stable soft-tissue coverage can be ensured.
