Functional outcome of management of infected non-union of humerus by limb reconstruction system (LRS)

Abstract

Introduction: The infected non-union of humerus resulting from surgical intervention to achieve bone healing are very difficult to manage by traditional methods. Materials & methods: We treated 20 infected non-union of diaphyseal fracture of humerus by LRS between 2009-15. All had prior surgical management, infected nonunion followed plating in 14 cases, 1 nailing case & 5 cases of external fixator. All patients had pain, atleast one sinus discharging pus and severe functional impairement of affected arm. There are 15 men and 5 women with a mean age of 39.7 years (range23-60yrs). Results: Bone healing achieved in 19 cases (95%). The eradication of infection was achieved in all cases. The mean time of union was 3.5 months (range 2-8 months). Good functional improvement was present. There were no major pin tract problems requiring removal of Schanz pins. 1 developed radial nerve palsy who recovered spotaneously. No patient required bone grafting and corticotomy procedure. Conclusion: The LRS alternative to the ring fixator in the treatment of infected non-union of humeral shaft, because of good patient compliance, decreased surgical learning curve, shortened duration of hospitalisation and immobilisation with good functional recovery.
