Pseudoarthrosis rarely presents as a diagnostic problem. However, since there are several etiologies, the specific cause may be difficult to identify. Radiologically, five morphological forms exist, although there is some overlap of these. The major form is hypertrophic and the other one is atrophic. The radiological characteristics are described illustratively. Often the etiological factors reflect on radiological presentation. Pseudo joint formation also occurs at transitional vertebrae of the lumbosacral spine, between spinous processes of L4-L5 and in late stages of congenital dislocations of hip.
