Introduction: Congenital radioulnar synostosis is a rare anomaly of the upper limb with functional limitations of the limb. However, it occurs more commonly than perceived and is often a part of syndromes, such as Crouzon, Apert\'s, and Poland\'s. The exact etiology is not clear, but there is genetic basis for the failure of differentiation between the radius and ulna.
Case report: A 6-year-old child with pain and limited mobility of the elbow joint came to the outpatient department, Department of Orthopedics, Government Medical College Amritsar, Punjab, India. Plain X-ray anteroposterior and lateral views were taken that showed bilateral superior radioulnar synostosis.
Conclusion: Diagnostic imaging like radiological studies can help the surgeons to plan for surgery of radioulnar synostosis.
