COSTAL ELEMENTS-CERVICAL RIB

Anatomy-Spine

COSTAL ELEMENTS-CERVICAL RIB

1. Due to elongation of the costal element of C7.
2. Extends from C7 to the first rib.
3. Usually appears at the age of puberty due to elongation of the neck and drooping of the shoulders.
4. Less symptomatic with a well ossified rib than with a fibrous band.
5. When cervical ribs are well ossified, the brachial plexus is likely to be pre-fixed (roots arising from C4, C5, C6, C7, C8).
