Richard A. Lindtner, Werner Schmoelz, in Biomechanics of the Spine, Abstract. Spinal injuries are common and potentially devastating injuries.
The thoracolumbar spine constitutes the most common site of spinal injuries. Depending on the mechanism of injury as well as the predominant forces and moments acting on the spine at the time of injury, typical thoracolumbar injury patterns result.
The thoracolumbar spine is the most common site of spinal injuries. Most of these injuries occur in males ( years) usually as the result of a significant-force impact, such as a motor vehicle accident or fall (Gertzbein ).Most injuries (52%) occur between T11 and L1 followed by L1 through L5 (32%) and T1 through T10 (16%) (GertzbeinGertzbeinKraus et al.

book prolapse, ligamentous injury, and epidural hematoma causing pressure on the spinal cord or nerve roots; these occur very rarely without a fracture. This topic focuses on thoracolumbar spine fracture.
The thoracic and lumbar spine connect at one of the more important locations in the body. The thoracolumbar junction is the place where the bottom thoracic vertebra (T12) meets the top lumbar vertebrae (L1).
This is also the attachment point for many of the body’s key muscles. My favorite muscle, the psoas, attaches on both [ ]. Denis, The three column spine and its significance in the classification of acute thoracolumbar spinal injuries.

The spine is the third most common site for cancer cells to metastasize, following the lung and the liver. Approximately % of patients with systemic cancer will have spinal metastasis; fortunately, only 10% of these patients are symptomatic.
Lumbar Spine. The Lumbar Spine has 5 vertebrae abbreviated L1 through L5 (largest). The size and shape of each lumbar vertebra is designed to carry most of the body’s weight.
Each structural element of a lumbar vertebra is bigger, wider and broader than similar components in. The thoracolumbar spine describes the area containing both the thoracic and lumbar vertebrae of the spine, states Radiology Master Class.
It is typically referred to in the case of a spinal injury. Thoracic spine, also know as T-spine, pertains to the upper back and abdomen area, and is one of three major sections of the spinal column, states.
Structural defects, due to traumatic injury or spinal degeneration, can rarely affect the area of the thoracic-lumbar juncture, as can idiopathic pain issues, including thoracolumbar syndrome. This essay focuses on the thoracolumbar region of the human vertebral column and its significance in some lower back pain syndromes.

• Discuss some of the debatable issues regarding low back pain and its treatment. • Explain the risk factors associated with low back disorders. • Understand the normal and injury mechanics of the lumbar spine.
• Identify important functional anatomy of the lumbar spine and its relation to injury mechanics. thoracolumbar spine Fractures of the thoracolumbar spine may involve (1) the vertebral body, (2) the laminae and articulating processes, and (3) the spinous processes or transverse processes.
The T12 to L2 area of the spine is most vulnerable to fracture. These nerve roots join distally to form 31 pairs of spinal nerves. The spinal cord is a cylindrical structure of nervous tissue composed of white and gray matter, is uniformly organized and is divided into four regions: cervical (C), thoracic (T), lumbar (L) and sacral (S), (Figure ), each of which is comprised of several segments.
Several types of analyses in biomechanics require estimates of both muscle force and stiffness. Simulations were performed using the two-state cross-bridge Bond Distribution-Moment muscle model of Zahalak (), together with other parameters for passive elasticity and tendon compliance, to estimate instantaneous stiffness and to compare these estimates with the wide range of values reported.
% of thoracolumbar spine fractures in adults occur at T12, L1 and L2, with 90% of all fractures being seen between T11 and L4. It is therefore important that T11/T12 is included on all trauma lumbar spine radiographs. 20% of thoracolumbar fractures are seen in association with other skeletal injuries.
The vertebral column is a mechanical marvel in that it must afford both rigidity and flexibility. The Spine as a Whole The segmental design of the vetebral column allows adequate motion among the head, trunk, and pelvis; affords protection of the spinal cord; transfers weight forces and bending moments of the upper body to the pelvis; offers a shockabsorbing apparatus; and serves as a pivot.
Regulation of rhythmic arm and leg movement is supported by somatosensory linkages in the form of interlimb reflexes[12,17,18]and neural coupling between lumbar and cervical spinal cord networks. Mechanical or activity-related spinal pain is most often aggravated by static loading of the spine (eg, prolonged sitting or standing), long-lever activities (eg, vacuuming or working with the arms elevated and away from the body), and levered postures (eg, forward bending of the lumbar spine).
Vertebral column, in vertebrate animals, the flexible column extending from neck to tail, made of bones called vertebrae. The major function of the vertebral column is to protect the spinal cord; it also is an attachment for many muscles.
In humans, it further transmits body weight in walking and standing. symptoms arising from the lumbar spine with alterations in the load response of the intervertebral discs. The annulus fibrosus is an essential constituent of the fibrous intervertebral joint.
Its collagen fibers resist forces and provide most of the stability necessary during motions of the vertebrae. Question: The Thoracolumbar Region Of The Spinal Cord Has The Outflow Fibers For _____.

Gymnastics is noted for involving highly specialized strength, power, agility and flexibility. Flexibility is perhaps the single greatest discriminator of gymnastics from other sports. The extreme ranges of motion achieved by gymnasts require long periods of training, often occupying more than a decade.
Gymnasts also start training at an early age (particularly female gymnasts), and the effect. Usually occurs as a result of high-energy trauma (e.g., road traffic accidents, falls from heights).
May occur spontaneously in patients with osteoporotic, neoplastic, or metabolic disorders of the spine. Initial on-the-scene evaluation involves performing primary survey with ABC assessment with. The lower back (where most back pain occurs) includes the five vertebrae in the lumbar region and supports much of the weight of the upper body.
The spaces between the vertebrae are maintained by intervertebral discs that act like shock absorbers throughout the spinal column to cushion the bones as the body moves. Ligaments hold the vertebrae in place, and tendons attach the muscles to the. racic spine, and the thoracic and the lumbar spine.
Between these is the mid-thoracic zone (T4–T9), where the spinal canal is at its narrowest (Fig. nucleus is rather small in the thorax.
Therefore protrusions are. usually of the annular type, and a nuclear protrusion is very rare in the thoracic spine. From a biomechanical perspective, there is some evidence that rodent and lagomorph (i.e. rabbit) IVDs have mechanical parameters that scale similarly to human IVDs although some important differences exist .
Some animals keep the notochordal cells throughout their life-time and other animals such as the human lose these cells when they. Thoracolumbar Spine Anatomy and Pathology - Midlumbar Vertebra Pathological Fracture of a Midlumbar Vertebra.

The human spine is often exposed to mechanical load in vocational activities especially in combination with lifting, carrying and positioning of heavy objects. This also applies in particular to nursing activities with manual patient handling. In the present study a detailed investigation on the load of the lumbar spine during manual patient handling was performed.
Nathan and Keller () measured lumbar intervertebral motion patterns following MFMA SMT and determined the frequency of PA stiffness. 9 Based on the findings of three subjects, the authors suggest that AAI, along with impedance analysis, may be used to quantify the mechanical response of normal and abnormal spine.
This report on the lumbar spinal canal and contents, and on the nerve root tunnels in the lumbar and sacral regions of the spine, is based on a study of 49 human cadavers at ages from birth to Genetics: Some causes of back pain, such as ankylosing spondylitis (a form of arthritis that involves fusion of the spinal joints leading to some immobility of the spine), have a genetic component.
Job-related factors: Having a job that requires heavy lifting, pushing, or pulling, particularly when it involves twisting or vibrating the spine. The knowledge of the lumbar spine biomechanics is essential for clinical applications. Due to the difficulties to experiment on living people and the irregular results published, simulation based on finite elements (FE) has been developed, making it possible to adequately reproduce the biomechanics of the lumbar spine.

Failed back surgery syndrome (FBSS) is a term embracing a constellation of conditions that describes persistent or recurring low back pain, with or without sciatica following one or more spine surgeries.A more functional definition proposes FBSS results when the outcome of lumbar spinal surgery does.Human nervous system - Human nervous system - Pain: There have always been two theories of the sensation of pain, a quantitative, or intensity, theory and a stimulus-specific theory.
According to the former, pain results from excessive stimulation (e.g., excessive heat or cold, excessive damage to the tissues). This theory in its simplest form entails the belief that the same afferent nerve.
