Background: Adult Diaphyseal Fractures of the radius and ulna require anatomical reduction and rigid internal fixation to restore the complex biomechanics of forearm rotation. Dynamic Compression Plate (DCP) fixation continues to be a widely practiced and dependable technique for achieving stable fixation. This study evaluates the functional and radiological outcomes of DCP plating in adult forearm diaphyseal fractures.

Methods: A clinical study was conducted on 15 adult patients with closed diaphyseal fractures of one or both forearm bones. All patients underwent open reduction and internal fixation using a 3.5 mm DCP plate. Postoperative assessment included radiographs at regular intervals to evaluate fracture union. Functional outcomes were assessed using the Anderson scoring system, focusing on pain, union, range of motion, and return of daily activities. Patients were followed up for a minimum of 6 months.

Results: Radiological union was achieved in 14 of 15 patients (93.3%) with a mean union time of 11.2 weeks. According to the Anderson criteria, 10 patients (66.7%) had excellent outcomes, 3 patients (20%) good outcomes, 1 patient (6.7%) fair outcome, and 1 patient (6.7%) poor outcome. Complications observed included superficial infection in 1 patient (6.7%), delayed union in 1 patient (6.7%), and transient stiffness of wrist/elbow in 2 patients (13.3%), which resolved with physiotherapy. No non-union, implant failure, or neurovascular complications were noted.
