Introduction:
Monteggia injuries are relatively rare in the pediatric population. They can be missed leading to complications arising from a chronic radial head dislocation. There is limited information about their proper management in the literature. Thus, their treatment remains controversial.
Case Report:
We present a case of a 10-year-old boy who was examined in the orthopedic outpatient clinic of our hospital, due to limited range of motion of his left elbow and difficulty in extending his left thumb, after a forearm injury which occurred 9 months before and was initially treated conservatively. After appropriate imaging was obtained, a Bado type I Monteggia lesion was diagnosed. This was treated by open reduction of the head of radius, osteotomy of the ulna and lengthening using an external fixator, as well as annular ligament reconstruction by the use of synthetic tendon graft. The patient was followed up for 18 months after surgery and during his last examination showed very good clinical and functional results.
Conclusion:
Missed Monteggia injuries in children are complex problems warranting a step-by-step approach. Their management with ulnar osteotomy, bone lengthening, and reconstruction of the annular ligament presents a viable option with excellent clinical, functional, and radiological outcomes.
