Plate over nail and bone graft for management of tibial non union after intramedullary fixation

Abstract

Abstract Non union after intramedullary nail fixation is difficult to treat. Many options are available for its management including nail exchange, bone graft while keeping the nail, nail removal and plating. Each method has its advantages and disadvantages. The aim of this study is to evaluate the results of management of tibial non union after intramedullary fixation using plate augmentation. Between January 2012 and December 2019, thirty four patients with nonunited fracture tibia previously treated with locked intramedullary nails were included in this study. The ages of patients ranged from 20 to 62 years ( an average age: 43 years). All patients were diagnosed to have aseptic nonunion. All patients achived bony union except 2. Bone union was achieved in a time ranged from 3 to 9 months (an average time 5 months). The average limb length discrepancy was 1 cm ( range 0 to 1.5 cm ). The reported complications were superficial wound infection in 2 cases, joint stiffness in 3 patients and nonunion in 2 cases. There were no intraoperative complications. All patients reported no pain at the fracture site during weight bearing at the final follow-up. We concluded that augmentation plate fixation is a good option for treatment of tibial nonunion after intramedullary nail.
