The bodies in the middle of the thoracic region are heart-shaped, and as broad in the antero-posterior as in the transverse direction.
The transverse processes arise from the arch behind the superior articular processes and pedicles; they are thick, strong, and of considerable length, directed obliquely backward and lateralward, and each ends in a clubbed extremity, on the front of which is a small, concave surface, for articulation with the tubercle of a rib.
The First Thoracic Vertebra has, on either side of the body, an entire articular facet for the head of the first rib, and a demi-facet for the upper half of the head of the second rib.

 Osteopathic Principles Key to Treating Patients with Thoracic Outlet Syndromes   (Site not responding. Last check: 2007-10-09)
Thoracic Outlet Syndrome is actually a group of upper extremity impingement syndromes involving the neurovascular bundle of the arm that are logical in progression, easy to diagnose and easy to help.
The thoracic outlet is approximately a four-centimeter area boundaried anteriorly by the manubrium of the sternum, laterally by rib one and its costal cartilage, and posteriorly by the body of T1.
Thoracic Outlet Syndromes are caused by a narrowing of one of the boundaries of the outlet.

Patients with thoracic outlet syndrome caused by nerve compression (neurogenic thoracic outlet syndrome) may be born with abnormalities of the two small muscles (the anterior and medial scalene muscles) that form one side of the thoracic outlet.
Tenderness of the thoracic outlet near the base of the neck just behind the collarbone is one of the two most telling signs of this condition.
Treatment involves removal of the compression in the thoracic outlet by removing the scalene muscles and/or the first rib, repair of the subclavian artery, administration of blood thinners (heparin) and a procedure called a sympathectomy, which improves blood flow to the fingers.

 The Thoracic Outlet Syndrome
Thoracic outlet syndrome (TOS) is due to compression/irritation of brachial plexus (BP) elements ("neurogenic TOS") and/or subclavian vessels ("vascular TOS") in their passage from the cervical area toward the axilla.
Thoracic outlet syndrome (TOS) can be defined as a set of symptoms existing due to compression/irritation of the brachial plexus (BP) and/or subclavian vessels in the cervical area.
A cervical rib or C7 transversomegaly is a strong argument for the diagnosis of TOS in the adequate clinical context.

A thoracic aortic aneurysm is a localized expansion of the wall of the aorta.

Thoracic aneurysms occur in the ascending aorta (25% of the time), the aortic arch (25% of the time), or the descending thoracic aorta (50% of the time).

The first two nerves supply fibers to the upper limb in addition to their thoracic branches; the next four are limited in their distribution to the parietes of the thorax; the lower five supply the parietes of the thorax and abdomen.
The twelfth thoracic is distributed to the abdominal wall and the skin of the buttock.
The anterior division of the twelfth thoracic nerve is larger than the others; it runs along the lower border of the twelfth rib, often gives a communicating branch to the first lumbar nerve, and passes under the lateral lumbocostal arch.

 Thoracic Outlet Syndrome
Thoracic Outlet Syndrome is a condition where nerves and/or vascular structures are compressed in the shoulder region by the first rib, accessory (cervical rib) when present, muscles or abnormal fibrous bands resulting in various symptoms such as pain, numbness, weakness and swelling of the arm and hand.
The other, much more rare variety of Thoracic Outlet Syndrome is produced by compression of the vascular structures, such as the subclavian vein or the subclavian artery leading to the formation of blood clots.
When the vein obstructs with blood clots, the symptoms are pain and swelling of the arm requiring emergency clot dissolving treatment and later operation to remove the first rib to relieve the compression.
