Background: Forearm diaphyseal fractures in adults are commonly encountered in orthopaedic practice. Operative treatment has become the gold standard in the management of these fractures. The purpose of this study was to evaluate the effectiveness of open reduction and internal fixation with dynamic compression plates in the management of both bone forearm fractures, in relation to achievement of union and functional results. Methods: This was a prospective observational study conducted on 36 patients of either sex with an average age of 36.38 years presenting to the Orthopaedic department of SHKM Government Medical College Hospital, Nalhar, Nuh, Haryana between March 2016 and March 2018, with a diagnosis of fracture both bone forearm. All the patients underwent open reduction and internal fixation with dynamic compression plates. The patients were followed up for a period of 1 year. Anderson et al. scoring system was used for assessment of results. Results: All the fractures united and the average time of union was 9.46 weeks. According to Anderson et al. scoring system, we had 30(83.33%) patients with excellent results, 4(11.11%) patients with satisfactory results, 1(2.78%) patient with unsatisfactory result and 1(2.78%) with failure. Conclusions: Thus results of our study demonstrate that open reduction and internal fixation with dynamic compression plates is a safe and effective surgical procedure for the treatment of both bone forearm fractures.
