Article by Putigna, Strohmeyer & Ursone 2007
The eponym Monteggia fracture is most precisely used to refer to a dislocation of the proximal radioulnar joint in association with a forearm fracture. These injuries are relatively uncommon, accounting for less than 5% of all forearm fractures. The ulna fracture is usually clinically and radiographically apparent. Findings associated with the concomitant radial head dislocation are often subtle and can be overlooked. The keys to successful diagnosis of a Monteggia fracture are clinical suspicion and radiographs of the entire forearm and elbow. Properly assessing the nature of this injury in a timely fashion is imperative in order to prevent permanent disability or limb dysfunction.
Synonyms and related keywords: fracture-dislocation involving the proximal ulna and radius, ulna fracture, Monteggia lesion, radial head dislocation, forearm fracture, broken arm

Monteggia Fracture Wheeless
Giovanni Monteggia (1814) first described fracture of proximal 1/3 of ulna in association with anterior dislocation of radial head;
- hence dislocation of radial head with fracture of proximal 1/3 of ulna is known as Monteggia's deformity.
- Mechanism:
- proposed mechanisms include direct blow & hyperpronation injuries as well as the hyperextension theory;

Type IV Monteggia fracture in a child
I
describe a type IV Monteggia fracture
in a 12-year-old boy with an initial
greenstick radial fracture. The concept of
a “symbiotic effect” is proposed, wherein
single-bone injuries at 2 levels shield each
other from excessive damage, and a rela-
tively better outcome than expected is
achieved.
Case report A 12-year-old boy suffered injuries to his left forearm and elbow in a fall from a bicycle. Radiographs of the left elbow and forearm revealed a type IV Monteggia lesion
