INTRODUCTION: @entity75 is a dislocation of the @entity135 associated with a @entity174 with the proximal third of the ulna. It is rare in @entity1 and the dislocation of the @entity135 is often missed at the time of injury. There are a lot of described treatment methods: open reduction of the @entity135 and reconstruction of the annular ligament combined with ulnar osteotomy, the same method without reconstruction of the annular ligament, gradual lengthening and angulation of the ulna by Ilizarov method without the opening of radiocapitelar joint. CASE OUTLINE: A 14-year-old @entity1 had been diagnosed with Monteggia lesion type Bado II three years before the admission to hospital. Previously nonoperatively treated, the missed @entity135 dislocation Bi-phase treatment had been done. Firstly, the distraction Ilizarov device was placed on the forearm, corticotomy of the ulna was done, distraction lasted fifteen days. Secondly, after achieving 1.5 cm of new bone and good level of the @entity135 , a reduction mechanism was incorporated into the Ilizarov device. The radiocapitelar joint was not opened, the reconstruction of the annular ligament was not done. After the @entity135 reduction and new bone maturation (1.5 months), the Ilizarov device was taken off. CONCLUSION: The described method of treatment has several important advantages: @entity135 reduction may be done without the joint opening, the recovery is very fast and easy after that; the elbow and forearm appear cosmetically very well after the operation; the treatment process is short, the arm is in use all the time, the absence from school is not needed, the achieved result is permanent.
