Abstract:
Pathology associated with anomalous transverse processes is uncommon and usually involves elongated C7 transverse processes in the so-called cervical rib syndrome. We report a single adult thoracic vertebra found to have duplicated transverse processes on the left side. We believe this to be the first report of a duplicated transverse process in man. The clinician and anatomist who view osteological material or imaging should consider this an extremely rare anatomical variation of the thoracic spine.

Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal...

Vertebral Column: Regions and Curvature
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
