All Monteggia fracture-dislocations require an urgent orthopedic assessment. Reduction is always required. Delayed or missed diagnosis is the most frequent. Monteggia fractures account for approximately 1% to 2% of all forearm fractures. Distal forearm fractures are far more frequent than midshaft. Monteggia fracture-dislocations consist of a fracture of the ulnar shaft with concomitant dislocation of the radial head. The ulnar fracture is usually obvious.

To identify this injury, it is essential to have x-rays that include both the elbow and forearm. The goals that must be accomplished are restoration of the length, alignment and rotation of moneggia ulna, reduction of the radial head which is usually spontaneousand identification and appropriate treatment of concomitant ligamentous and bony injuries about the elbow in order to ensure ulnohumeral stability. Complications related to adult Monteggia fractures include those so frequently encountered in elbow trauma.

Monteggia Fracture – Pediatric

In children, most of these injuries can have excellent outcomes, provided there is accurate and timely diagnosis, and that radiocapitellar reduction is maintained. What advice should I give to parents? The ulnar head supplements the triangular fibrocartilage complex Fracure at the wrist. Closed reduction was unsuccessful. L8 – 10 years in practice. Large C-arm allows easier imaging than the mini C-arm, and provides a view of a greater proportion of the forearm, which can be helpful in judging ulnar deformity.

Avoid probing open wounds. The peak incidence is years of montetgia. This holds true for all projections, and whether the radial head is ossified or not.


There is an ulna midshaft fracture. Osteoporosis must be taken into account when treating adult fractures. The line drawn down the shaft of the radius does not pass through the centre of the capitellum. In the rare setting in which a radiocapitellar pin is indicated, certain precautions should be taken.

HPI – Fell from her height. If it is not straight, it indicates a plastic mpnteggia injury. Reducing it over the radial head with forceps traction or using a Freer elevator as a shoehorn may be successful, but sharp division followed by suture repair in a reduced position is often required. D ICD – To ffacture feedback, please email rch. The most common operative repair is an ORIF. Pediatric length unstable ulna fractures An approach to the subcutaneous border of the ulna between the extensor carpi ulnaris ECU and flexor carpi ulnaris FCU is made.

A thorough inventory of all injured structures will be critical in formulating an appropriate treatment plan.

By using this site, you agree to the Terms of Use and Privacy Policy. It should be straight, not bowed.

The ulna should be reduced and fixed first and will typically lead to spontaneous reduction of the radius. Delayed diagnosis is the most frequent complication.

Lisfranc Jones March Calcaneal. A small incision is made over the olecranon tip in line with the medullary canal. Epub Dec 8.

Evaluation and Management of Monteggia Fractures

The most common associated motor deficit is a posterior interosseous nerve palsy. Maisonneuve fracture Le Fort fracture of ankle Bosworth fracture. Even larger fractures, or medial coronoid fragments that would benefit from buttressing, may be reduced and plated via an FCU splitting approach.


These will not uncommonly accompany posterior fracture configurations fracrure in adults. It will be painful to move the elbow in any plane. After undergoing closed reduction, the radiocapitellar joint is noted to remain non-concentric. Additionally, the prolonged immobilization of the elbow required for closed treatment typically leads to unacceptable elbow stiffness. Great care should be made to achieve anatomic length, alignment and rotation, as residual ulnar deformity may lead to radiocapitellar instability.

If it does not, a dislocation should be suspected.

Monteggia Fractures – Trauma – Orthobullets

Improperly treated, these lead to severe disability related to loss of elbow and forearm range of motion. It promotes stability of the radial head dislocation and allows very early mobilisation to prevent stiffness.

Plain X-rays are usually sufficient, but CT can be of value in preoperative planning. The alignment and stability of the radius monteggla ulna originate from three ligamentous structures: PMC ] [ PubMed: Fracture of the ulnar metaphysis distal to coronoid process with lateral dislocation of the radial head.

Complete ulnar fractures will require operative management. Management of the ulna will vary based on the subtype of fracture: An upper arm tourniquet should be placed, and the arm should be prepped and draped as high above the elbow as possible.
