Sporadic and Non-syndromic Bilateral Humeroradial Synostosis: A Case Report

Non-syndromic bilateral humeroradial synostosis is a very rare congenital anomalies of the upper limbs. This condition often occurs in conjunction with various syndromes and is associated with a positive family history. Herein, we report a 6 year old boy with non-syndromic bilateral humeroradial synostosis, without aplasia, hypoplasia or family history. Both elbows were constant at 90 degrees flexion and the patient was not able to perform supination and pronation. Internal rotation, external rotation, and abduction movements of shoulder were normal. Except bilateral humero radial synostosis, findings of physical examinations, lab tests, and imaging were normal. Parents rejected surgical treatment.
