Fractures of both bone of the forearm are relatively common injuries which can challenge the treating orthopaedican. Healing occurs reliably after closed treatment but malunion, with resultant decreased rotation of the forearm is common and has been associated with poor results 
. Rotation of the forearm is a complex interaction between the radius and ulna and restoration of this movement depends on both on accurate reduction of fractures, this is achieved by ORIF using LC-DCP 
The “Limited Contact Dynamic Compression Plate”, was developed by Perren S. M. et to release the new concept of biological internal fixation. Grooves on the undersurface of the LC-DCP improved blood circulation. There is decreased damage to contact between plate and bone. It also allows for a small bone bridge beneath the plate at the most critical area, which is otherwise weak due to a stress concentration effect. In addition, there is more even distribution of the plate than in conventional plates. This study is undertaken to assess the results of diaphyseal fractures of BBFA using LCDCP to study the advantages and its complications.
Materials and Methods: Patients who are admitted in Adichunchanagiri Institute of Medical Sciences are taken for study after obtaining their consent. This is prospective study from May 2013 to May 2016.
Results: This study consists of 50 cases of fracture Both Bone Forearm Fractures. All cases were openly reduced and internally fixed with 3.5 mm LCDCP. Fracture was common in second and third decade with average age of 43 years (18-64 years). In our study, male preponderance was found with 74% males and 26% female patients. Side affected 32 (64%) Left side and 18 patients (36%) right side. Mode of injury in the present study, RTA (60%), fall (30%) and assault (10%). An average time for union was 17 weeks Results were evaluated by Andersons scoring system. In present study, we had 45 patients (90%) with excellent results, 4 case (8%) as satisfactory and 1 case (2%) as failure which required refixation. In the present study there was 3 case (6%) of superficial infection, 1 case (2%) of non-union of radius which required refixation with bone grafting.
Conclusion: LC-DCP can be considered the best mode of treatment for closed diaphyseal fractures of both bones forearm.
