Introduction: Monteggia fracture-dislocations are a rare entity and they represent less than 2% of forearm fractures, the diagnosis can be missed up to 50% most of the time. The standard treatment is ulnar osteotomy with angulation and lengthening and internal fixation, Open reduction of the radial head, temporary fixation of the radial head with a trans capitellar k -wire, and immobilization for 6 weeks in pediatrics.

Case Report: We described a case of an 8years old boy with a neglected Monteggia fracture-dislocation, he presented to us 3 months after the injury, with a cubitus varus deformity of the left elbow and he was treated surgically and cast immobilization and physiotherapy.

Conclusion: To avoid missing the injuries, each patient should undergo a thorough comprehensive clinical approach and adequate radiological imaging. Different treatment methods are available for neglected Monteggia fractures and each option should be exhausted to save the radial head starting with the less invasive approaches. This report concerns a surgical technique to reduce a chronic dislocation of the radial head using an ulnar osteotomy with angulation and lengthening and internal fixation with Open reduction of the radial head with temporary fixation of the radial head with a trans capitellar k-wire and immobilization with the forearm in the neutral rotation was maintained for 6 weeks, the patient had appreciable recovery after surgery and physiotherapy, He regained painless function of the forearm, good range of elbow and forearm range of motion, and maintenance of the reduction of radial head.
