Introduction:
• A cervical rib is an additional rib which arises with the 7th cervical vertebra and is usually attached to the 1st rib, closed to the (Chest OPD) insertion of scalenus anterior.
• Cervical rib may be unilateral or bilateral.
• It is more common on right side.
• Cervical rib may have a free anterior end, be connected to the first rib by a fibrous band, or may articulate with the first rib.
Material & Methods: Chest OPD
• The present study was done in the Dept. of Anatomy and Dept. of Pulmonary Medicine,
• The sample consisted of 250 consecutive cases of all ages and both sexes presenting in Pulmonary Medicine OPD as well as indoor wards.
• This study was done over a two month period.
• Chest radiographs (P-A view) of these subjects were examined for presence of cervical rib.

Results
• A cervical rib was present in 3 cases – 2 bilateral and 1 unilateral on left side (incidence 1.2%).
• Nobody had any symptoms due to cervical rib. No other bony thoracic abnormalities was seen.
Clinical Importance Chest OPD
In the majority of subjects, it is an incidental finding on a chest radiograph advised for unrelated symptoms.
Presence of cervical rib should be borne in mind for correct diagnosis and therapeutic purposes.
Usually it is asymptomatic, but in less than 10% of subjects it may give rise to various neurological, vascular or local symptoms.
Cervical Rib Syndrome: Chest OPD
The brachial plexus and subclavian artery pass through a narrow triangle bounded by two scalenei and the 1st rib. When the base of this triangle is raised by presence of a cervical rib,brachial plexus and subclavian artery may be compressed and produce neurological & vascular symptoms respectively.

Thoracic Outlet Syndrome
A cervical rib is one of the etiological factors in thoracic outlet syndrome. Other causes of that produce similar symptoms :
• Fibrous band passing from scalenus medius or scalenus anterior to its insertion
• Misaligned fracture of clavicle
• Hypertrophied subclavius muscle
Conclusion:
The incidence of cervical rib was found to be 1.2% and it may be found incidentally without causing any symptoms or may cause vascular, neurological or local symptoms.
