What are the planes of flexion in the thoracic spine?
The angles of the joints in the thoracic spine allow for motion in all planes: rotation, flexion/extension, and lateral flexion. However, the ribs block excessive lateral flexion from occurring. Sagittal plane flexion and extension is also available in the region of the thoracic spine.
What is thoracic extension of the spine?
When the term “extension” is used about the thoracic spine, the meaning is a reduction in relative flexion. While there may not be true extension of the thoracic spine, this reduction in flexion is important for movement of the scapula and arm.
How much can the thoracic spine flex?
From neutral, the thoracic spine can flex to approximately 35° of additional flexion. Thus, in full flexion, the thoracic spine demonstrates up to 75° of flexion. Conversely, the thoracic spine only moves 20° to 25° of extension. Therefore, if the normal position is 40°, the fully extended is still 15-20° of flexion.

What are the characteristics of the thoracic vertebrae?
The primary characteristic of the thoracic vertebrae is the presence of costal facets. There are 6 facets per thoracic vertebrae: 2 on the transverse processes and 4 demifacets. The facets of the transverse processes articulate with the tubercle of the associated rib. The demifacets are bilaterally paired and located on the superior and inferior posterolateral aspects of the vertebrae. They are positioned so that the superior demifacet of inferior vertebrae articulates with the head of the same rib that articulates with the inferior demifacet of a superior rib. For example, the inferior demifacets of T4 and the superior demifacets of T5 articulate with the head of rib 5.

When transitioning from one region, there is no immediate change between cervical ...
What is the critical zone of the thoracic spine?
As Dr. Chris Fox wrote in a previous post on thoracic spine anatomy, " In the thoracic spine, T4-9 is known as the critical zone because the vertebral canal is narrowest here; it also has reduced blood supply (Egan et al, 2011). T6 is a tension point; here motion of the spinal core versus canal converge in different directions." Improving the neural mobility in the thoracic spine can help improve movement and decrease pain in the joints above and below.

What is the Thoracic Spine?
The thoracic spine is the twelve vertebrae of the middle segment of the vertebral column. While all vertebrae have rib components, they are usually small and make up the transverse processes in regions other than the thorax (Drake, Vogl & Mitchell, 2015).
What happens if the lumbar spine does not rotate?
If the thoracic spine does not rotate, the lumbar spine is forced to rotate more, which could play a role in low back pain or injury. As Bogduk (2005) describes, rotation of more than 3 ° at any lumbar segment could damage the articular surface and tear collagen fibers that make up the disc between each vertebra.
How many thoracic vertebrae rotate?
In many cases, the last two to three thoracic vertebrae begin to demonstrate movement characteristics of the lumbar spine. On average, each thoracic vertebra can rotate approximately 3 °. Therefore, the entire thoracic spine should demonstrate between 30 -35 ° of total rotation to each side (Neumann, 2010).
How much does the lumbar spine rotate?
However, the lumbar spine also rotates, albeit less than the thoracic. The lumbar vertebrae demonstrate approximately 2 ° of rotation between each, resulting in 10 ° of rotation to each side. Thus, the total thoracolumbar rotation should be approximately 45 ° in each direction.
What does "extension" mean in a scapula?
When the term “extension” is used about the thoracic spine, the meaning is a reduction in relative flexion. While there may not be true extension of the thoracic spine, this reduction in flexion is important for movement of the scapula and arm.
What is the body of a thoracic vertebra?
The body of a thoracic vertebra is somewhat “heart-shaped,” and is larger than the cervical but smaller than the lumbar vertebrae in size. The body also has small, smooth, and somewhat concave costal facets for the attachment of the ribs. Ribs are generally inserted between two vertebrae, such that each vertebra contributes to articulating with half of the articular surface. Each vertebra therefore has a pair of superior articular facets that face posteriorly and a pair of inferior articulating facets that face anteriorly (except for T12). This means that the rib will articulate with the inferior costal facet of the upper vertebrae and the superior costal facet of the lower vertebrae. Transverse processes arise from the arch found behind he superior articular processes and pedicles, and are thick and strong with a clubbed end and a small concave surface for the articulation with the tubercle of a rib. These processes are directed obliquely backward towards the spinous process and lateralward.
Where are the thoracic vertebrae located?
The thoracic vertebrae are located in the middle section of the vertebral column, specifically inferior to the cervical vertebrae and superior to the lumbar vertebrae. These vertebrae span the large majority of the chest cavity area.

Like typical vertebrae, they are separated by intervertebral discs. However, they are various anatomical features ...
Why do thoracic vertebrae increase in size?
Thoracic vertebrae increase in size as they descend towards the lumbar vertebrae; this is because the lower vertebrae must be able to support more of the body’s weight when a person is standing due to the effects of gravity. To summarize, the main anatomical components of a thoracic vertebra are: Body. Spinous process.
What is the ribs of a vertebra?
Ribs are generally inserted between two vertebrae, such that each vertebra contributes to articulating with half of the articular surface. Each vertebra therefore has a pair of superior articular facets that face posteriorly and a pair of inferior articulating facets that face anteriorly (except for T12).
What are the distinguishing features of the thoracic vertebrae?
Distinguishing features of the thoracic vertebrae include the presence of facets on the sides of the bodies for articulation with the heads of the ribs, and facets on the transverse processes of all, except the 11th and 12th vertebrae, for articulation with the tubercles of the ribs.
