A rare primary bone dysplasia disorder characterised by short stature with severe shortening of limbs, genu vara deformity and enlarged joints with movement limitation particularly affecting the hip joints. Radiological findings show coxa vara, generalised metaphyseal irregularities of the tubular bones (including cupping, fraying and splaying), which are more severe in the femur and forearm bones than the metacarpals and phalanges and vertebral abnormalities including ovoid vertebral bodies with anterior rectangular protrusions and severe platyspondyly.
