A rare primary bone dysplasia characterised by the association of spondylometaphyseal dysplasia, generalised joint laxity, and dentinogenesis imperfecta. Main skeletal abnormalities comprise short stature, narrow chest, scoliosis, mesomelic limb shortening, and brachydactyly. Radiographic features include severe metaphyseal irregularities of the tubular bones, platyspondyly with coronal clefts, cone-shaped epiphyses of the hands, square iliac wings, and coxa valga. Additional extraskeletal manifestations like pulmonary hypoplasia, cystic renal disease, and non-obstructive hydrocephalus have also been reported.

Odontochondrodysplasia, also called Goldblatt syndrome, is a very rare syndrome associating chondrodysplasia with dentinogenesis imperfecta. To date, 11 patients have been reported. Chondrodysplasia has characteristics of mesomelic limb shortening, joint laxity, platyspondyly with coronal clefts, brachydactyly and coxa valga. The affected patients have no intellectual deficit. The condition is most probably hereditary, transmitted as an autosomal recessive trait.
