Special case of bilateral postaxial longitudinal deficiency in a 3-year-old child

Abstract

Introduction: Considering the variety of their clinical, radiological, and etiological manifestations, congenital abnormalities of the upper limbs represent complex diseases. They can be separated into brachydactyly, duplication, differentiation failure, and training failure. Ulnar longitudinal deficiency, a deformity that belongs to the first group and is uncommon, manifests differently in the forearm and the hand. Postaxial longitudinal deficiency and unilateral radial humerus synostosis are common diagnoses. Case Report: We present a case of a 3-year-old boy who had radio-humeral synostosis on the right side along with a typical congenital failure of longitudinal bilateral ulnar development. Conclusion: While traditional radiography still plays a significant role in diagnosis and prognosis, ultrasonography and magnetic resonance imaging (MRI) will soon be valuable diagnostic tools. Each case is different, and the treatments and the time of surgery are specific, the optimal treatment remains the prosthetic door; however, the placement of a prosthetic on a sensitive member requires early intervention of the patient and his family.
