摘　　要：BACKGROUND Monteggia and equivalent lesions are relatively rare but result in severe injuries in childhood,typically affecting children between 4 and 10 years old.The diagnosis and treatment of an equivalent Monteggia lesion is more complicated than those of a typical Monteggia fracture.This type of lesion may be challenging and may lead to serious complications if not treated properly.Pediatric Monteggia equivalent type I lesions have been reported in a few reports,all of which the patients were all over 4 years old.CASE SUMMARY A 14-mo-old boy was referred to our clinic after falling from his bed 10 d prior.With regard to the clinical examination,an obvious swollen and angular deformity was noted on his right forearm.Plain radiographs and reconstructed computed tomography scans showed a Monteggia type I fracture and dislocation.Magnetic resonance imaging(MRI)confirmed a type I Monteggia equivalent lesion consisting of ulnar fracture and Salter-Harris type I injury in the proximal radius.The radial head was still in the joint,and only the radial metaphysis was displaced anteriorly.Open reduction and pinning of both displaced radial and ulnar fractures achieved an excellent result with full function.CONCLUSION We recommend MRI examination or arthrography during reduction,especially if the secondary ossification center has not appeared.
