title: Pelvic dysplasia associated with arthrogrypotic changes in the lower extremities. A new syndrome.
abstract: Two sisters exhibit arthrogrypotic changes in the lower extremities associated with a previously undescribed pelvic dysplasia. The pelvic dysplasia is characterized by: severe abnormalities of ossification with markedly widened triradiate cartilages; irregular, notched acetabulae; marked hypoplasia of the ilia; notching of the iliac wings; and delayed ossification of the capital femoral ossific nucleus. The elder girl has bilateral clubfeet, as well as flexion contractures of both knees. The younger girl has a right talipes equinovarus and left hip dislocation. Autosomal recessive inheritance is suggested. This distinctive syndrome should be considered in the differential diagnosis of the patient with arthrogryposis.
