“…15 The rotational position of the forearm at presentation is the key to determining the direction of reduction. 5 Our patient presented with pronation deformity, and thus supination was needed for reduction. Similarly, a supination manoeuvre was performed for reduction of the radial head for a patient whose forearm was in hyperpronation.…”

“…As the patient fell backward onto a dorsiflexed wrist, pronated forearm, and an extended elbow, rotation of the body over the affected arm fixed to the ground may have created further pronation. This would also generate varus strain to the elbow, eventually disrupting the annular ligament and the posterior border of the quadrate ligament, [5][6][7][8] and dislocating the radial head anterolaterally. An intact distal radio-ulnar joint could have provided a stable fulcrum.…”

“…5,6 The proximal radio-ulnar joint is most stable in supination, where the contact between the radius and ulna is maximal, and the interosseous membrane, annular ligament, and anterior fibres of the quadrate ligament are all taut, thus drawing the radial head snugly against its notch in the ulna.…”

European Journal of Trauma Ab stractIsolated radial head dislocation in adults is extremely rare and has been predominantly posterior. A case of isolated, acute anterior dislocation of the radial head in an adult is reported. A 26-year-old male sustained an isolated radial head dislocation following a fall on the outstretched hand. The dislocation was treated by closed reduction and transcapitellar Kirschner wire fixation. At final follow-up the patient had recovered full range of motion of the elbow. Radiographs of the forearm including elbow and wrist were normal. A management algorithm for this injury is proposed, based on a review of the literature.

Radial head button holing: a cause of irreducible anterior radial head dislocation

et al. 2016

"Buttonholing" of the radial head through the anterior joint capsule is a known cause of irreducible anterior radial head dislocation associated with Monteggia injuries in pediatric patients. To the best of our knowledge, no report has described an injury consisting of buttonholing of the radial head through the annular ligament and a simultaneous radial head fracture in an adolescent. In the present case, the radiographic findings were a radial head fracture with anterior dislocation and lack of the anterior fat pad sign. Magnetic resonance imaging (MRI) clearly demonstrated anterior dislocation of the fractured radial head through the torn annular ligament. The anterior joint capsule and proximal portion of the annular ligament were interposed between the radial head and capitellum, preventing closed reduction of the radial head. Familiarity with this condition and imaging findings will aid clinicians to make a proper diagnosis and fast decision to perform an open reduction.
