PURPOSE Monteggia fracture is a combination of ulnar fracture and radial head dislocation. Despite of low incidence, Monteggia fracture has a problem in the treatment. So satisfactory results could not be achieved easily. The purpose of this study was to analyze factors affecting functional results in Monteggia fracture. MATERIALS AND METHODS From January 1990 to June 1998, we retrospectively reviewed 24 patients out of 40 patients who had been treated for Monteggia fracture. The functional assessment was performed with Broberg and Morrey system10). RESULTS Excellent and good results were achieved in 16 cases(66.6%), whereas fair and poor results in 8 cases(33.4%). Satisfactory results were obtained in 66.6% overall.
According to the Bado classification, functional results were not different significantly between types. According to the mechanisms of injury, unsatisfactory results were obtained in 8 of 17 patients with high energy injury. Monteggia fractures with ulnar fracture at the diaphyseal level showed satisfactory results significantly compared to others. In terms of the methods of internal fixation, the plate and screw fixation showed satisfactory results in 14 of 16 patients whereas tension band wiring or intramedullary nailing showed unsatisfactory results in 6 of 8 patients. CONCLUSION In Monteggia fractures, factors affecting functional result may be the mechanism of injury, the level of ulnar fracture and the method of internal fixation.

Authors experienced a rare injury in a 5-year-old girl with Monteggia fracture and concomitant lateral condyle fracture of humerus with radial nerve injury. This combined injury has not been reported in the literature. This unusual fractures were treated by open reduction and K-wire fixation of lateral condyle fracture and transcapitellar K-wire fixation of radial head dislocation. An excellent result was obtained with operative treatment.
In 1814, Monteggia first desHribed a fracture of proximal third of the ulna with dislocation of radial head, and Bado classified and included all fracture of ulna at any level with a dislocation of radial head under the name of Monteggla lesion In 1967.
In adults, the prognosis Is poor due to many complications such as nerve injury, unreduced radial head, heterotrophic ossification, nonunion and malunion. The most important factors In achieving good results in adult Monteggia lesions are early accurate diagnosis, rigid internal fixation of the ulna and complete reduction of the radial head as soon as possible.
The authors reviewed 12 cases of Monteggia fracture In adults who were treatod at department of orthopaedic surgery, Sung-Ae General hospital from 1989 jan. to 1991 Dec. with 17 months mean follow-up.
The results obtained were as follows: 1. Male was 10 cases and female 2 cases.
2. The causes of injury were traffic accident In 9 cases, machinery injury in 2, fall down in 1 3. Location of ulna fracture was as follows; metaphysis was 4, proximal 1/3 in 6 cases, proximal 1/3 junction in 1, metaphysls and proximal 1/3 in 1.
4. According to Bado classificatlon, type I was 58%. type II 25%, tyre III 17%, type IV 0%.
5. Treatments of dislocated radial head were closed reduction in 9 Gases open reduction in 1 case, and excision in 2 cases.
6. Fractures of ulna were all treated with open reduction and internal fixation with plate in 9 cases. IM nailing in 1 case, tension band wiring in 2 cases.
7. Palsy of posterior interosseous nerve was in 2 cases with complete recovery within 6 months.
8. The results(Bruce, et. at) 17 month follow-up in average were 2 excellent, 5 good, 2 fair and 3 poor.
