Abstract
Fracture of the radial head is the most common skeletal injury in the adult elbow. Most radial head fractures occur in those who are between 20 and 60 years of age. The most common mechanism of injury involves a fall on the outstretched hand with the forearm pronated and the elbow partially flexed. The anterolateral one third of the head surface lacks thick articular cartilage and strong subchondral support, making this region more susceptible to fracture Most fractures of the radial head involve a component of articular impaction in addition to shear. The simplest pattern of displacement involves failure of a margin of the head in compression. Higher-energy injuries involving the radial neck often occur in the setting of associated failure of the soft tissues of the elbow and/or forearm. A common injury pattern involves a radial head fracture, coronoid fracture, and elbow dislocation (the “terrible triad”) with collateral ligament disruption. Elbow dislocation is seen in up to 10% of radial head fractures; conversely, radial head fractures are reported as occurring in 5% to 10% of elbow dislocations. The load-bearing function of the radial head becomes increasingly important as more supporting structures are compromised. In the face of elbow dislocation, fractures affecting greater than about 30% to 40% of the radial head should be fixed to restore lateral elbow support and elbow joint stability We aimed in this study to evaluate the results of ORIF type II Redial-Head fractures (Mason type II) in the adults Subjects and MethodsThis prospective quasi-experimental study involved 20 patients with type II fractures of head radius in Department of Orthopedics, faculty of medicine, Assiut university between the period of December 2018 till May 2019 All patients subjected to the following : Clinical, Radiological examination All patients were treated with ORIF on an average of 2 days (range, 0–13 days) after the initial injury.
