![]() There was an average rotation of 12.3° and an average translation 5.3mm of the fracture fragment proving that the model was unstable under loading conditions. “The fracture model was verified as being unstable by applying 4.5N of load in the non-stabilized condition. “We chose fiberglass casting to compare to the Exos brace due to its lighter, more durable, porous characteristics compared to traditional plaster casts and also due to the fact it is a common treatment in the setting of conservative care.” This type of fracture would likely be managed by surgery, however, we opted for a severe worst case and highly unstable fracture model to delineate any differences in stability between both casting and bracing interventions.” A worst-case distal radius fracture was created using six cadaveric forearms that resulted in a comminuted extra-articular and unstable distal radius fracture. “The study was done by the Foundation for Orthopaedic Research and Education, in Tampa, Florida using a very high level of engineering and detail throughout the study. “The Exos technology was developed for management of these types of fractures and we wanted to confirm stabilization capabilities through research that the Exos thermo-formable bracing products were equivalent to traditional fiberglass casting.” and no data existed prior to this study comparing stabilizing efficacy of bracing to fiberglass casting.” The thermo-formable bracing system used in the study was DJO Global’s Exos Upper Extremity bracing system.Īnn Davis, product manager for Exos Upper Extremity bracing system commented on the study to OTW saying, “Distal radius fractures are one of the most common musculoskeletal injuries in the U.S. The study was entitled, “ Radiographic evaluation of acute distal radius fracture stability: A comparative cadaveric study between a thermo-formable bracing system and traditional fiberglass casting.” Treatment of radial head fractures depends on the specific characteristics of the fracture using the Mason classification.There is another option for severe, unstable and comminuted distal radius fractures, says new work published in the August 2017 edition of Clinical Biomechanics. Radial head fractures may be difficult to visualize on initial imaging but should be suspected when there are limitations of elbow extension and supination following trauma. Combined fractures involving both the ulna and radius generally require surgical correction. These fractures are treated with immobilization or surgery, depending on the degree of displacement and angulation. Isolated midshaft ulna (nightstick) fractures are often caused by a direct blow to the forearm. It should be noted that these fractures may be complicated by a median nerve injury. A nondisplaced, or minimally displaced, distal radius fracture is initially treated with a sugar-tong splint, followed by a short-arm cast for a minimum of three weeks. In adults, distal radius fractures are the most common forearm fractures and are typically caused by a fall onto an outstretched hand. Depending on the degree of angulation, buckle and greenstick fractures can be managed with immobilization. Greenstick fractures, which have cortical disruption, are also common in children. ![]() Incomplete compression fractures without cortical disruption, called buckle (torus) fractures, are common in children. ![]() If initial imaging findings are negative and suspicion of fracture remains, splinting and repeat radiography in seven to 14 days should be performed. ![]() Evaluation with radiography or ultrasonography usually can confirm the diagnosis. A fall onto an outstretched hand is the most common mechanism of injury for fractures of the radius and ulna. Fractures of the radius and ulna are the most common fractures of the upper extremity, with distal fractures occurring more often than proximal fractures. ![]()
