Five patients with campomelic dysplasia who have survived (age range 7 to 20 years) are described, all of whom have molecular or cytogenetic evidence of campomelic dysplasia. The phenotype and radiological features of these cases are consistent. Complications in this group include recurrent apnoea and upper respiratory infections, progressive kyphoscoliosis, mild to moderate learning difficulties, short stature, and dislocation of the hips. All five had very similar facial features. The radiological features include hypoplastic scapulae, defective ischiopubic ossification, absent or hypoplastic patellae, and spinal dysraphism.

Campomelic dysplasia (CMD) is a rare skeletal dysplasia resulting from mutations in SOX9. It is usually lethal in the first year of life. Three-quarters of the cases with a male karyotype have complete or partial sex reversal. 1 The skeletal changes in the neonatal period are well recognised and include hypoplastic scapulae, bowing of the long bones, vertical narrow iliac bones, and absence of ossification of the thoracic pedicles.
