Abstract: Objective    To evaluate the effect of repairing of annular ligament in the treatment of pediatric chronic Monteggia fracture based on ulnar osteotomy.    Methods    Between March 2013 to January 2022, a retrospective case series study was conducted to analyze 30 children with chronic Monteggia fracture-dislocations. In all cases were treated with open reduction of the radial head and lengthening-angulation osteotomy of ulnar, in of which 17 cases underwent only lengthening-angulation osteotomy of ulna (Group A), 13 combined annular ligament repairing (Group B). Following up was performed for mean 18 (range, 12 to 96) months postoperatively. The outcome was evaluated by the Kim score and range of motion, and radiography.    Results    There was no statistical difference in the excellent-and-good rate between group A and group B (P>0.05), according to Kim score. There was no statistical difference in the total elbow range of motion between group A and group B (P>0.05). There were no complications of nonunion in follow-up radiographs. Relocation of radiocapitellar joint were observed in 28 cases, radial head subluxation recurred in 2 cases.    Conclusions   Lengthening-angulation osteotomy of ulna is the key in the treatment of chronic Monteggia fractures, on the basis of which the repairing of annular ligament is not a major determinant for prognosis.
