Thanatophoric dwarfism
Caused by mutation of the fibroblast growth factor receptor 3 gene, which is located on the short arm of chromosome 4. Is characterized by severe shortening of the ribs, restricted lung volume, and severe respiratory distress that leads to death within a few hours of birth  
Type I: characterized by marked underdevelopment of the entire skeleton, short-curve long bones, and metaphyseal flaring (telephone receiver-like appearance). The pelvic bones are noticeably underdeveloped, and the acetabular roof is flat. The vertebral bodies also are very flat and underdeveloped. Cloverleaf skull may or may not be present.
Type II: long bones are not as short as in type I, and they are not bent or bowed. The metaphyses are flared and cupped. The vertebral bodies are flat but not as severely as is in type I TD. Almost all fetuses with type II TD have severe cloverleaf skull.

Dunn view.
Using MRI as the standard, and a cut-off alpha angle of 50.5° for diagnosis of cam-type FAI, the 90° Dunn view was found to be 91% sensitive and 88% specific, with a positive predictive value of 93%, negative predictive value of 84%, and accuracy of 90%. There was also strong correlation between alpha angles on the Dunn view and on MRI (Pearson correlation of 0.7)
