Congenital Radioulnar Synostosis: A Case Report and Review of Various Osteotomies

INTRODUCTION: Congenital radioulnar synostosis is a rare deformity of the forearm characterized by a malformation of the proximal aspect of the radius and ulna. Various modalities of treatment options available include observation, excision of the synostosis and placing an interposition material, or performing derotation osteotomy. Several types of osteotomies at different forearm levels have been described in the literature. CASE REPORT: A 5-year-old female presented with bilateral congenital radioulnar synostosis which was treated with percutaneous corrective osteotomy and Joshi’s external stabilizing system fixator application. CONCLUSION: We describe the management of congenital radioulnar synostosis in a 5-year-old female child using a novel minimally invasive, single-staged procedure . This innovative technique provided the patient with a good functional outcome and she could return to her daily activities with a satisfactory range of motion.
