Figure 2

Surface rendered computed tomography images of perosomus elumbis case DK1. a) Surface rendering^a to show bone surfaces only. Absence of lumbar, sacral and coccygeal spine can be appreciated. The most posterior thoracic vertebrae are abnormally shaped and the posterior rib pairs are abnormally crowded. b) Same data set as in a), but rendered with bone and soft tissue surfaces. The latter has been set to have a degree of transparency in the reconstruction thus allowing visualisation of the calf s overall morphology and its relation to the underlying skeletal abnormalities.
