Although anterior transolecranon fracture dislocations are well recognized in adults,13 they have been reported in only a small series of children.8 To our knowledge, only 11 cases of transolecranon fracture variants have been reported in literature.2,3,8,13,15,17 Transolecranon fracture dislocation resembles an anterior Monteggia lesion because the radial head dislocates anterior to the capitellum. However, the proximal radioulnar joint remains aligned and intact in transolecranon fracture dislocations, which differ from Monteggia-type fracture dislocations.8 In this case report, we report a child diagnosed with an anterior transolecranon fracture dislocation with an associated avulsion fracture of the coronoid process of the ulna. Unlike the 11 previously reported cases, this report contains the first case with an associated avulsion fracture of the coronoid process. A 7-year-old boy fell from a height of 2meters andwas admitted to the emergency department with pain, swelling, and deformity in the right elbow. While the right elbow’s range of motion was
