A study of management of nonunion of tibia by ilizarov method

Abstract

: Background: FDA Panel definition of nonunion ---- "Established when a minimum of 9 months has elapsed since injury and fracture shows no visible progressive signs of healing for 3 months". Tibial nonunion is most frequently met while considering the other long bone nonunion. This is mostly due to increase in the number of tibial fractures both close and open and in high-speed Road Traffic Accident (RTA) injuries. Failure of union may be due to an inappropriate mechanical environment or infection and in some cases, there is no apparent reason. The Ilizarov method relies on distraction osteogenesis and is used not only for segmental defects, but also to complex malalignment with minimal surgery. Ilizarov technique has the additional advantage of efficient fixation, early ambulation, elimination of bone grafting with minimal complications. Ilizarov provides stability and at the same time allow micro movements with axial loading with neo vascularization due to distraction, giving an excellent biological environment for fracture healing. Methods: Sample size of twenty (20) patients fulfilling the inclusion criteria admitted to Department of Orthopaedics, Chettinad Hospital and Research Centre, Kelambakkam. Study period from to November 2020.
