In patients with extensive comminution of the ulnar shaft, a distractor is applied and used to maintain length posterior monteggia lesion jupiter pdf and reduction of the ulnar fracture until the contoured LC-DCP is formally fixed to the ulna. 7% of all elbow fractures and dislocations in adult patients.
Rotational fracture dislocations of the elbow which do not fit into these categories are named Monteggia-like lesions. Type I: 60%: Fracture of the proximal or middle third of the ulna with anterior dislocation of the radial head (most common in children and young adults): Type II: 15%: Fracture of the proximal or middle third of the ulna with posterior dislocation of the radial head (70 to 80% of adult Monteggia fractures). posterior monteggia lesion jupiter pdf · A Monteggia fracture is defined as a fracture of the proximal ulna combined with a luxation of the radial head.
