Mcq montagia fracture most common feature:
a- upper 3rd of shaft of ulna***
b- diastasis of distal radio ulnar joint
c- distal radioulnar ligament disruption
d- full down on outstretched hand I shows this.
N.B → The Monteggia fracture is a fracture of the proximal third of the ulna with dislocation of the head of the radius.
Monteggia fracture...........Fall on an outstretched hand with the forearm in excessive pronation (hyper-pronation injury). The Ulna fractures in the proximal one-third of the shaft due to extreme dislocation. Depending on the impact and forces applied in each direction, degree of energy absorption determines pattern, involvement of the radial head and whether or not open soft tissue occurs.
N.B → Monteggia fracture :proximal ulnar shaft , associated with radial head dislocation .
Smith fracture: distal radius fracture with ventral angulation commonly associated with ulnar styloid fracture.
Colle's fracture: distal radius fracture with dorsal angulation commonly associated with ulnar styloid fracture.
Bennett's fracture: a fracture of the proximal end of the first metacarpal which extends into the first carpo-metacarpal joint.
Salter- Harris 2 fracture: fracture through the growth plate and metaphysis.
