Non-union of long bone fractures which was treated with Limb reconstruction system was followed up and the functional outcome was analysed in this study.Incidence of fracture long bone increased day by day due to increased RTA leading to increased incidence of nonunion. Controversy in treatment of nonunion regarding use of devices. Various devices are illizarov ,intramedullary nail, DCP, LCP, LRS etc. Basic requirements to all biomechanical stability & biological vitality of bones well provided by external fixator. Among these LRS external fixator simplest & effective devices with good union rates. LRS is easy to construct frame .LRS is less cumbersome to patients. LRS also have the facility to distract & compress the fracture & allow dynamization of fracture which are the essential principles in treatment of nonunion.Bone grafting, docking of fracture sites also can be done to achieve union. There is still controversy about union rates & complication associated with LRS in treatment of nonunion. So this study will be conducted to assess the union rate in fracture nonunion of longbone to assess complications associated with the devices. To evaluate the union rate with LRS in treatment of nonunion fracture long bones. To assess the duration of treatment with LRS in fracture nonunion of long bones.Fractures of long bone failed to unite by 6 months.All types of nonunion long bone. Radiological evidence of nonunion in fractures of longbones. Patient willing to give written informed consent. Patients who undergo LRS Fixator application for Nonunion long bones will be analysed for the following factors .Preoperatively the following factors are taken into consideration ,bone involved, Deformity, Condition of skin, Infection at nonunion site, Range of motion of adjacent joints, Shortening of the limb. Postoperatively the union is assessed by ,abnormal mobility at fracture site, Joint Movements, Loosening of LRS pins and Pin track infections. Radiologically the following factors are seen like ,Gap at fracture site ,Callus formation, Regenerate in cases of distraction osteogenesis. we selected 30 cases and analysed found that around 80% of union achieved by Limb reconstruction system.
