Fracture dislocations of the forearm

angulated fracture at the junction of the proximal and middle third of ulna accompained by ANTERIOR dislocation of the radial head
etiology:
* transmission of force thorugh the hand and forearm with the elbow partially flexed
* interosseous ligament "drags" the radius with the distal two-thirds of the ulna
MUGR mnemonic
* Monteggia with...

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...

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...

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...

Introduction In a Monteggia fracture dislocation, it is important to reduce the ulnar fracture completely. Extensive plastic deformation of the proximal ulna may make reduction by closed manipulation impossible.
Case presentation We report the case of a four-year-old Caucasian boy in whom the plastic deformation of the proximal ulna was reduced, and this...
