If an ulna fracture is present, always look for a radial head dislocation. Monteggia fracture-dislocations can be easily missed on x-ray.

There must also be a true AP and lateral view of the elbow (not just a forearm view) to assess the radiocapitellar joint. 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. What are the potential complications associated with this injury?.What is the usual ED management for this fracture?.Do I need to refer to orthopaedics now?.When is reduction (non-operative and operative) required?.What radiological investigations should be ordered?.How common are they and how do they occur?.It is recommended to assess the integrity of the collateral ligaments and presence of any mediolateral instability, as in an adult horse, this may be a poor candidate for treatment if the congruency of the elbow joint cannot be maintained or kept stable.Monteggia fracture-dislocations - Fracture clinics These 3 were all younger horses (eldest was 3 years old).

The 3 horses treated surgically in the literature all ended up free of lameness, although none stated return to athletic performance. The most challenging part of the surgical fixation appears to be reduction of the fracture due to the antebrachial musculature, with mechanical distraction or chemical muscle relaxation being used. They have been successfully managed surgically with reduction and internal fixation using plates (DCP in all cases).

In the equine literature type 1 (n=3) and type 4 (n=1) fractures have been reported in the literature. Type 4 – cranial (anterior) dislocation of the radial head + fracture of the proximal ⅓ of the radius + fracture of the ulna at the same level.Type 3 – lateral or craniolateral (anterolateral) dislocation of the radial head + fracture of the ulnar metaphysis.Type 2 – caudal (posterior) or caudolateral (posterolateral) dislocation of the radial head + fracture of the ulnar diaphysis with caudal angulation.Type 1 – cranial (anterior) dislocation of the radial head + fracture of the ulnar diaphysis with cranial angulation (middle or proximal ⅓ of the ulna).The injury was discussed and a classification system was defined in a paper by José Luis Bado 5. 1 and there only appear to be three other mentions in the equine literature 2–4, with the first of those being in 1980. This has been reported in horses, most recently in 2009 by Jalim et al. Named after Italian surgeon Giovanni Battista Monteggia, the definition is an ulnar fracture (in the proximal third) with radial dislocation. The Monteggia fracture is an example of this. Some lesions retain the name of equivalent lesions in human medicine, although perhaps not in frequent use. Instruments are obviously the most common example of this. Many things in medicine are named after the person who came up with it or first described it (i.e.
