Abstract
Since the original description by G.Monteggia of a fracture of the ulna associated with dislocation of the radial head, attention hns been focused on the immediate recognition and treatment of this fracture. but the dislocation of the radial head is not infrequently missed. The purpose of this study is to analyze the clinical results according to types of the fracture and methods of treatment. The authors reviewed twenty-four patients treated for Monteggia fracture at the Department of Orthopaedic Surgery, Korea University Hospital from January 1986 to April 1995. The mean follow up period was 21 months (12 month - 37 months).
The results were as follows:
1. According to Bado classification, there were 15 cases(63%) of Type 1, 3 cases(12%) of Type 2, 2 cases(8%) of Type 3, and 4 cases(17%) of Type 4.
2. The location of the ulna fracture site were proximal metaphysis in 7 cases(29%), proximal 1/3 in 15 cases(63%), and middle 1/3 in 2 cases(8%).
3. Treatment for ulna fracture were open reduction and internal fixation in 21 cases(88%), and closed reduction in 3 cases(12%).
4. Treatment for dislocated radial head were closed reduction in 20 cases(84%), open reduction in 2 cases(8%), and radial head resection in 2 cases(13%).
5. Transient palsy of posterior interosseous nerve was observed in 3 patients(13%).
6. The results by Bruce et al criteria were excellent in 7 cases(29%), good in 9 cases(38%), fair in 6 cases(25%), and poor in 2 cases(8%).
