Unfused spinous process, which is really failure of fusion of the neural arch, is a relatively common anatomical variant and is part of the spectrum of spina bifida occulta.

This should be differentiated from accessory ossicles of the spinous process, which appear after non-fusion of the secondary ossification center (or centers in bifid spinous processes). These appear as a well-corticated fragment adjacent to the tip of the spinous process with a vertical or near-vertical lucency.

The importance lies in patients with potentially traumatic spinal injuries, in which it is important to identify this variant and avoid potential pitfall of diagnosing a fracture. A well-defined cortical margin is a helpful clue.
