In 1814 Monteggia described two cases of fracture of the proximal part of the ulna with anterior dislocation of the radial head.

Since then, there have been many reports of this type of fracture dislocation. Bado named Monteggia lesion as a fracture of ulna at any level and a dislocation of radial head.

Thrity-five patient with Monteggia fracture were treated at department of Orthopaedic Surgery, Ehosun University Hospital from 1985. January to 1991 December. Twenty-seven patient, who were followed for a minimum of one year, subject of this review.

The results were as follows:

1. Among the 27 patients, male is about 3 times more than female.

2. The cause of injuries were traffic accident in 15, fall down in 10, belt injury in 1 and direct blowing in 1

3. Classification into 4 type by Bados method disclosed that type I accounts for 51.9% of cases, type II for 14.8%, type III for 22.8% and type IV for 11.1%

4. Sites of ulna fractures were upper one thlrd in 8, junction of upper and middle 1/3 in 11, middle 1/3 in 5, distal 1/3 in 1 and segmental 2.

5. Closed reduction of radial head dislocation was done in 13 cases open reduction in 6 cases, and excision in 8 cases.

6. All of the fractures of ulna were treated with open reduction and internal fixation with plate in 16, Rush pin in 6 and wiring in 5.

7. The partial posterior interosseous nerve injury was noticed in 3 cases and recovered completely within 8 weeks.

8. With the criteria of Bruce et al(1974), the result were excellent in 11, good in 7, fair in 5 and poor in 4.
