Methicillin– resistant Staphylococcus aureus (MRSA) infected gap non –union of long bones fractures is a challenge to manage. Treatment options are limited such a Ilizarov bone transport, vascularized bone free transfer etc. These techniques have complications and require expertise. We present a rare case with MRSA infected nonunion and bone defect 5cm of ulna which was managed with the induced membrane formation.

A 33-years old male presented to outpatient department, 2 months after internal fixation on both left bone forearm fractures (Gustillo I). There was pus discharge from the operative site of ulna. Culture results: MRSA, C-Reactive Protein (CRP): 2,58 (0–5), Erythrocyte Sedimentation Rate (ESR): 42 (0–20). Intravenous (iv) Teicoplanin and Rifampicin were administrated and after one month no topic symptoms and CRP- ESR were normal. One month later he had again actively draining sinus (CRP: 1,47 ESR:22). The implant (ulna) was removed and a gap 5 cm was created at the fracture site (necrotic-infected bone debrided), which was filled by cemented spacer (Tobramycin and vancomycin). An external fixator was applied to ulna. Radius was not involved. Post op. iv the same antibiotics for 4 weeks. At the end of 8 weeks, the spacer was removed and the gap was filled with autologous cancellous bone graft (iliac crest).

After 5 months the patient was reviewed. No any clinical and functional problems. Radiographics and CT-images were showed osseous consolidation.

This technique (called as ‘Masquelet’) gives promising result in the management of infected long bone defects in upper extremity.
