Case Discussion

The malformation was present since birth.

The pathogenesis of this disorder is not known for certain.

Patterson(1) included four types of deformity in CCRS:

- a simple ring usually occuring transversely around the limb or digit.

- a deeper ring often associated with abnormality of the part distally,         usually lymphedema.

- fenestrated syndactyly or lateral fusion of adjacent digits at their distal    ends with proximal fenestration between the intervening skin and soft    tissue.

- intrauterine amputation, in which the soft tissue are more affected than    the bone.

80% of patients with CCRS have been reported to have syndactyly, hypoplasia, brachydactyly, symphalangism and symbrachydactyly.

40% to 50% of patients have club foot, cleft lip, cleft palate and cranial defects.
