cervical rib

A unilateral or bilateral congenital anomaly of the 1st thoracic rib or 7th cervical rib, affecting up to 0.5–1% of the population, 15% of whom have an associated thoracic outlet syndrome due to associated neural and arterial defects. Cervical ribs range from type I, a short bar extending from the transverse process, to type IV, a complete extra rib articulating with the sternum.

cervical rib

A short, floating, rudimentary rib attached to the lowest neck vertebra on one or both sides. In about 10% of cases the rib causes compression of arteries or nerves in the neck, leading to pain and tingling, or sometimes more serious effects, in the arm or hand.

However, Hampe (1992) justifies its provisional inclusion of the specimen in the genus Kronosaurus based on the large size of the skeleton, the short neck with 12 vertebrae, the expanded opisthotic, the small and unpaired supraoccipital, and the cervical rib facets extending through the entire length of the centra.
It has also been reported that congenital abnormalities of the ribs are more common in women and on the right side.10 Cervical rib, being a supernumerary and accessory rib, develops from the 7th cervical vertebra.

Cervical rib is usually asymptomatic and is detected as an incidental finding when a chest or neck x-ray is taken for some other purposes.
The most common abnormality was a postfixed brachial plexus, implying a large conjoined middle and inferior trunk, susceptible to pathological stretching over the 1st rib or an anomalous cervical rib. Prefixed brachial plexus anomalies were also fairly common in patients presenting with symptoms attributable to the higher nerve roots, or in patients whose symptoms were not distinctively attributable to specific nerve roots within the brachial plexus.
Previously, the name was designated according to the etiologies of compression, such as scalenus anticus, costoclavicular, hyperabduction, cervical rib, or first rib syndromes.
They have also found that the formation of cervical ribs were more common in North Sea woolly mammoths than in today's elephants and were astonished to find such numbers of cervical ribs among them.
Thrombolytic therapy is usually tried by catheter infusion of alteplase in the vein itself [7, 8], while decompression of the thoracic outlet by first or cervical rib resection, division of anomalous musculotendinous bands, and scalenectomy remain the ultimate treatment [7, 8].

Abstract: A cervical rib, or supernumerary (extra) rib arising from the 7th cervical vertebra, is a congenital abnormality that occurs in less than 1% of the population.
