INTRODUCTION: According to the AO (Arbeitsgemeinschaft fur Osteosynthesefragen) documentation center, forearm fractures accounts for 10-14% of all fractures. Various treatment modalities are available depending upon the fracture type. In this study 20 patients with diaphyseal fractures of both bones forearm were studied and treated with Intramedullary L-rods by closed technique. All these cases were treated at our institution from July 2012 to Jun 2013. The minimum duration of follow up was 6 months. AIMS & OBJECTIVES: 1) to find the effectiveness of intramedullary L rods over other alternative methods 2) to evaluate functional and anatomical outcome based on clinical and radiological follow up. 3) To evaluate the difficulties associated with this technique and suggestions to overcome it. MATERIALS & METHODS: Through assessment of the patient including clinical examination of the injury, systemic examination, ruling out other injuries and radiological assessment was done before deciding on the surgical procedure. Sample size: 20 patients satisfying the following criterion. Inclusion criteria 1) Age>17yr 2) Diaphyseal fractures of radius and ulna. 3) Closed fractures and gustilo Anderson type 1 and 2 fractures Exclusion criteria 1) Fractures >4 weeks old. 2) Pathological fractures, gustilo Anderson type 3 open fractures and associated epiphyseal radius and ulna injury. STATISTICAL ANALYSIS: The final results were based on Clinical and radiological assessments i.e. entry point wound status and migration of nail, pain and tenderness at the fracture site, range of movement of elbow and wrist, limb length disparity, three cortices union, callus formation with reference to time, Implant status and varus/ valgus angulation. Functional outcome was assessed using Grace and Eversman scoring system. RESULTS & CONCLUSIONS: CLOSED REDUCTION AND INTERNAL FIXATION WITH INTRAMEDULLARY L -RODS is an easy and fast method for treating forearm fractures with minimal blood loss and scar. Full range of movements was achieved without any significant complication.
