Lumbar developmental malformation: intertransverse pseudarthrosis.

Developmental malformations of lumbar transverse processes commonly include hypertrophy of the transverse process, overgrowth of the transverse process, and persistence of the transverse process epiphysis. To date, the intertransverse pseudarthrosis malformation has not been reported. In this case report, we identified a case of intertransverse pseudarthrosis through X-ray imaging, which was confirmed by CT scanning. And intertransverse pseudarthrosis of spine was proved by Surgery.
