Spondylometaphyseal dysplasia, corner fracture type (SMDCF) is a skeletal dysplasia characterized by short stature and a waddling gait in early childhood. Short stature may be present at birth or develop in early infancy. Individuals may present with short limbs and/or short trunk. Radiographic features include enlargement and corner fracture-like lesions of the metaphyses, developmental coxa vara, shortened long bones, scoliosis, and vertebral anomalies. Limited joint mobility and chronic pain are common. Vision impairment and glaucoma have been reported. [from GeneReviews]

Fracture or fragmentation at the lateral portion of the metaphysis of a long bone. The radiographic appearance is that of a small corner of metaphysis separated from the metaphyseal edge by thin linear radiolucency. This feature can be observed in child abuse but fragmented appearance of the metaphysis or facture-like lesions can also be detected in the setting of certain skeletal dysplasias. [from HPO]
