Masquelet technique in management of infective non-union of long bones- A prospective study

Abstract

Introduction and Aim: Masquelet’s technique is a 2-staged procedure, for treatment of infected segmental bone defect. 1st stage involves radical debridement with antibiotic-induced cement spacer. During second stage, the spacer is removed and the autologous bone graft is applied into the biomembrane formed. In this study, we evaluate the Masquelet’s technique for the management of infective non-union of long bones. Materials and Methods: 15 patients with infective non-union of long bones- tibia, femur and a case of congenital pseudoarthrosis of tibia, were treated with Masquelet’s technique. They underwent 2 stages of procedures 6-8 weeks apart and was followed up for about 9 months and radiological and clinical outcomes were assessed. Results: Out of 15 patients with infective non-union, 8 patients attained union. Out of the 7 patients with failure of the technique, higher failure rates were attributed to Pseudomonas infection. Conclusion: Masquelet’s technique is a cost-effective method for treating infective segmental non-unions, not requiring special training or sophisticated instruments. This method shows good results with Gram positive infections. Although, the outcome with Pseudomonas aeruginosa infection, have not shown satisfactory results.
