A case of arthrogryposis multiplex congenita with absence of abdominal rectus muscles

Abstract

Arthrogryposis multiplex congenita is a rare syndrome characterized by nonprogresive congenital joint contractures. The most common findings include round face appearance accompanied by micrognathia, midline capillary hemangioma, adduction and internal rotation of shoulders, multiple joint contractures of upper and lower extremities. Deliveries are difficult due to joint contractures and breech presentation is common. There are extremity fractures secondary to traumatic labor. In most patients with arthrogryposis multiplex congenita, a defect in neural influence on the developing muscles may be responsible for the absence or maldevelopment of some muscle groups. In this study, we present an arthrogryposis multiplex congenita case with absence of abdominal rectus muscles and review the literature.
