Radius and ulna shaft fractures, also known as both bone forearm fractures, are common fractures caused due to direct or indirect trauma. Open reduction and internal fixation with plating by two separate incisions is a standard and widely accepted mode of fixation. We report a case where we approached the fracture with a single dorsal incision. An eighty years old female had fractures of both radius and ulna shaft with Gustilo Anderson type two open injury. We managed the patient with single-stage debridement, open reduction, and dynamic compression plate (DCP) fixation of both bones with a single dorsal curvilinear incision and followed up postoperatively for one year. At the end of the last follow-up, the patient had no pain with a full range of movement. There were no wound-related issues. Radiologically complete union occurred without complications mentioned in the literature, such as synostosis.: We found that under specific circumstances such as open injury where two separate incisions for radius and ulna are inappropriate, a single dorsal curvilinear incision for radius and Ulna midshaft fractures is a safe and effective alternative method.
