![]() ![]() What radiological investigations should be ordered?Īnteroposterior (AP) and lateral x-rays of the forearm that include the wrist and elbow should be ordered. However if the ulna has a greenstick fracture or 'plastic bowing', deformity is mild and the fracture can be easily missed. The forearm may look deformed if the ulna fracture is displaced. It will be painful to move the elbow in any plane. There may be diffuse swelling around the elbow, but the degree is variable. Type I fractures are usually a result of a fall on an outstretched hand with hyperpronation or hyperextension of the forearm. These fractures are a less common injury compared to forearm fractures. How common are they and how do they occur? ![]() Lateral dislocation of the radial head with fracture of the ulna metaphysisĪnterior dislocation of the radial head with fracture of the shaft (diaphysis) of the ulna and radiusģ. Posterior dislocation of the radial head with fracture of the ulna shaft (diaphysis) or metaphysis Table 1: Bado classification of Monteggia fracture-dislocations.Īnterior dislocation of the radial head with fracture of the ulna shaft (diaphysis) The Bado classification system (Table 1) describes four types. How are they classified?Ī Monteggia fracture-dislocation refers to dislocation of the radial head (proximal radioulnar joint) with fracture of the ulna. Delayed or missed diagnosis is the most frequent complication. If an ulna fracture is present, always look for a radial head dislocation.Īll Monteggia fracture-dislocations require an urgent orthopedic assessment. Monteggia fracture-dislocations can be easily missed on x-ray.
