Facet syndrome is a syndrome in which the facet joints (synovial diarthroses) cause painful symptoms. [1] In conjunction with degenerative disc disease, a distinct but functionally related condition, facet arthropathy is believed to be one of the most common causes of lower back pain. [2] [3]

Contents

Signs and symptoms

The symptoms of facet joint arthropathy depend entirely on the location of the degenerated spinal joint, the severity of the damage and the amount of pressure that is being placed on the surrounding structures. [4] It's important to note that the amount of pain a person experiences does not correlate well with the amount of degeneration that has occurred within the joint. Many people experience little or no pain while others, with exactly the same amount of pathology, experience chronic pain.[ citation needed ]

Additionally, in symptomatic facet arthropathy the location of the degenerated joint plays a significant role in the symptoms that are experienced. People with degenerated joints in the upper spine will often feel pain radiating throughout the upper neck and shoulders (cervical facet syndrome.) That said, symptoms often manifest themselves in the lumbar spine, since they are highest here due to the overlying body weight, mobility and geometry. Affected persons usually feel dull pain in the lumbar spine that can radiate into the buttocks and legs. Typically, the pain is worsened by stress on the facet joints, e.g. by lumbar extension and loading (the basis of the Kemp Test) or lateral flexion but also by prolonged standing or walking.[ citation needed ]

Pain associated with facet syndrome is often called "referred pain" because symptoms do not follow a specific nerve root pattern. This is why patients experiencing symptomatic facet syndrome can feel pain in their shoulders, legs and even manifested in the form of headaches. [5]

Cause

Like many other joints throughout the human body, facets can experience natural degeneration from normal aging. Over time, the cartilage within the joints can naturally begin to wear out, allowing it to become thin or disappear entirely which, in turn, allows the conjoining vertebrae to rub directly against one another with little or no lubricant or separation. A result of this rubbing is often swelling, inflammation causing pain.[ citation needed ]

Over time, the body will naturally respond to the instability within the spine by developing bone spurs, thickened ligaments or even synovial cysts that contact nerve roots exiting the spinal column. [6]

While primarily caused through natural wear and tear and degeneration, facet syndrome can also occur as a result of injury to the spine, or lifestyle choices. These causes can include:[ citation needed ]

Pathophysiology

55% of facet syndrome cases occur in cervical vertebrae, and 31% in lumbar. Spinal osteoarthritis is known as spondylosis. [7] Pathology of the C1-C2 (atlantoaxial) joint, the most mobile of all vertebral segments, accounts for 4% of all spondylosis. [8]

Facet joints

The facet joints are formed by the superior and inferior processes of each vertebra. The first cervical vertebra has an inferior articulating surface but, as it does not restrict lateral or posterior translation, is not always considered a proper zygoma [9] [10] (zygoma is Greek for "yoke", i.e. something that restrains movement). In the lumbar spine, facets provide about 20 percent of the twisting stability in the low back. Each facet joint is positioned at each level of the spine to provide the needed support especially with rotation.[ citation needed ]

Facet joints also prevent each vertebra from slipping over the one below. A small capsule surrounds each facet joint providing a nourishing lubricant for the joint. Also, each joint has a rich supply of tiny nerve fibers that provide a painful stimulus when the joint is injured or irritated. Inflamed facets can cause a powerful muscle spasm.[ citation needed ]

Diagnosis

Facet arthropathy or 'facet syndrome' can typically be diagnosed through a physical examination, MRI, x-rays and/or a diagnostic block into the suspected joint. [5]

Treatment

In general, anti-inflammatory drugs are prescribed initially. This medical treatment is usually accompanied by physiotherapy to increase back and stomach muscles. Thus, the spine can be both relieved and stabilized. [11] If these conservative measures do not bring about betterment, minimally invasive procedures such as a facet infiltration can be conducted to offer relief. In this procedure, a local anesthetic is injected directly into the respective joint, usually in combination with a cortisone preparation (corticosteroid). For long-term relief in more severe cases, Radio-frequency ablation or Rhyzotomy, where the anterior and posterior spinal nerve root is burnt may be performed. [12]

<span class="mw-page-title-main">Lumbar spinal stenosis</span> Medical condition of the spine

Lumbar spinal stenosis (LSS) is a medical condition in which the spinal canal narrows and compresses the nerves and blood vessels at the level of the lumbar vertebrae. Spinal stenosis may also affect the cervical or thoracic region, in which case it is known as cervical spinal stenosis or thoracic spinal stenosis. Lumbar spinal stenosis can cause pain in the low back or buttocks, abnormal sensations, and the absence of sensation (numbness) in the legs, thighs, feet, or buttocks, or loss of bladder and bowel control.

A laminectomy is a surgical procedure that removes a portion of a vertebra called the lamina, which is the roof of the spinal canal. It is a major spine operation with residual scar tissue and may result in postlaminectomy syndrome. Depending on the problem, more conservative treatments may be viable.

<span class="mw-page-title-main">Spondylosis</span> Degeneration of the vertebral column

Spondylosis is the degeneration of the vertebral column from any cause. In the more narrow sense it refers to spinal osteoarthritis, the age-related degeneration of the spinal column, which is the most common cause of spondylosis. The degenerative process in osteoarthritis chiefly affects the vertebral bodies, the neural foramina and the facet joints. If severe, it may cause pressure on the spinal cord or nerve roots with subsequent sensory or motor disturbances, such as pain, paresthesia, imbalance, and muscle weakness in the limbs.

<span class="mw-page-title-main">Cervical vertebrae</span> Vertebrae of the neck

In tetrapods, cervical vertebrae are the vertebrae of the neck, immediately below the skull. Truncal vertebrae lie caudal of cervical vertebrae. In sauropsid species, the cervical vertebrae bear cervical ribs. In lizards and saurischian dinosaurs, the cervical ribs are large; in birds, they are small and completely fused to the vertebrae. The vertebral transverse processes of mammals are homologous to the cervical ribs of other amniotes. Most mammals have seven cervical vertebrae, with the only three known exceptions being the manatee with six, the two-toed sloth with five or six, and the three-toed sloth with nine.

<span class="mw-page-title-main">Degenerative disc disease</span> Medical condition

Degenerative disc disease (DDD) is a medical condition typically brought on by the normal aging process in which there are anatomic changes and possibly a loss of function of one or more intervertebral discs of the spine. DDD can take place with or without symptoms, but is typically identified once symptoms arise. The root cause is thought to be loss of soluble proteins within the fluid contained in the disc with resultant reduction of the oncotic pressure, which in turn causes loss of fluid volume. Normal downward forces cause the affected disc to lose height, and the distance between vertebrae is reduced. The anulus fibrosus, the tough outer layers of a disc, also weakens. This loss of height causes laxity of the longitudinal ligaments, which may allow anterior, posterior, or lateral shifting of the vertebral bodies, causing facet joint malalignment and arthritis; scoliosis; cervical hyperlordosis; thoracic hyperkyphosis; lumbar hyperlordosis; narrowing of the space available for the spinal tract within the vertebra ; or narrowing of the space through which a spinal nerve exits with resultant inflammation and impingement of a spinal nerve, causing a radiculopathy.

<span class="mw-page-title-main">Retrolisthesis</span> Posterior displacement (but not dislocation) of a vertebra relative to the one below it

A retrolisthesis is a posterior displacement of one vertebral body with respect to the subjacent vertebra to a degree less than a luxation (dislocation). Retrolistheses are most easily diagnosed on lateral x-ray views of the spine. Views where care has been taken to expose for a true lateral view without any rotation offer the best diagnostic quality.

<span class="mw-page-title-main">Spondylolisthesis</span> Displacement of one spinal vertebra compared to another

Spondylolisthesis is the displacement of one spinal vertebra compared to another. While some medical dictionaries define spondylolisthesis specifically as the forward or anterior displacement of a vertebra over the vertebra inferior to it, it is often defined in medical textbooks as displacement in any direction. Spondylolisthesis is graded based upon the degree of slippage of one vertebral body relative to the subsequent adjacent vertebral body. Spondylolisthesis is classified as one of the six major etiologies: degenerative, traumatic, dysplastic, isthmic, pathologic, or post-surgical. Spondylolisthesis most commonly occurs in the lumbar spine, primarily at the L5-S1 level, with the L5 vertebral body anteriorly translating over the S1 vertebral body.

<span class="mw-page-title-main">Cauda equina syndrome</span> Nerve damage at the end of the spinal cord

Cauda equina syndrome (CES) is a condition that occurs when the bundle of nerves below the end of the spinal cord known as the cauda equina is damaged. Signs and symptoms include low back pain, pain that radiates down the leg, numbness around the anus, and loss of bowel or bladder control. Onset may be rapid or gradual.

Congenital vertebral anomalies are a collection of malformations of the spine. Most, around 85%, are not clinically significant, but they can cause compression of the spinal cord by deforming the vertebral canal or causing instability. This condition occurs in the womb. Congenital vertebral anomalies include alterations of the shape and number of vertebrae.

<span class="mw-page-title-main">Bertolotti's syndrome</span> Medical condition

Bertolotti's syndrome is a commonly missed cause of back pain which occurs due to lumbosacral transitional vertebrae (LSTV). It is a congenital condition but is not usually symptomatic until one's later twenties or early thirties. However, there are a few cases of Bertolotti's that become symptomatic at a much earlier age.

<span class="mw-page-title-main">Spinal disc herniation</span> Injury to the connective tissue between spinal vertebrae

A spinal disc herniation is an injury to the cushioning and connective tissue between vertebrae, usually caused by excessive strain or trauma to the spine. It may result in back pain, pain or sensation in different parts of the body, and physical disability. The most conclusive diagnostic tool for disc herniation is MRI, and treatment may range from painkillers to surgery. Protection from disc herniation is best provided by core strength and an awareness of body mechanics including posture.

<span class="mw-page-title-main">Facet joint</span> Joint between two adjacent vertebrae

The facet joints are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.

<span class="mw-page-title-main">Radiculopathy</span> Medical condition

Radiculopathy, also commonly referred to as pinched nerve, refers to a set of conditions in which one or more nerves are affected and do not work properly. Radiculopathy can result in pain, weakness, altered sensation (paresthesia) or difficulty controlling specific muscles. Pinched nerves arise when surrounding bone or tissue, such as cartilage, muscles or tendons, put pressure on the nerve and disrupt its function.

<span class="mw-page-title-main">Cervical spinal stenosis</span> Medical condition

Cervical spinal stenosis is a bone disease involving the narrowing of the spinal canal at the level of the neck. It is frequently due to chronic degeneration, but may also be congenital. Treatment is frequently surgical.

<span class="mw-page-title-main">Diastematomyelia</span> Medical condition

Diastematomyelia is a congenital disorder in which a part of the spinal cord is split, usually at the level of the upper lumbar vertebra in the longitudinal (sagittal) direction. Females are affected much more commonly than males. This condition occurs in the presence of an osseous, cartilaginous or fibrous septum in the central portion of the spinal canal which then produces a complete or incomplete sagittal division of the spinal cord into two hemicords. When the split does not reunite distally to the spur, the condition is referred to as diplomyelia, which is true duplication of the spinal cord.

<span class="mw-page-title-main">Neurogenic claudication</span> Medical condition

Neurogenic claudication (NC), also known as pseudoclaudication, is the most common symptom of lumbar spinal stenosis (LSS) and describes intermittent leg pain from impingement of the nerves emanating from the spinal cord. Neurogenic means that the problem originates within the nervous system. Claudication, from the Latin word for to limp, refers to painful cramping or weakness in the legs. NC should therefore be distinguished from vascular claudication, which stems from a circulatory problem rather than a neural one.

<span class="mw-page-title-main">Spinal disease</span> Diseases involving the vertebral column

Spinal disease refers to a condition impairing the backbone. These include various diseases of the back or spine ("dorso-"), such as kyphosis. Dorsalgia refers to back pain. Some other spinal diseases include spinal muscular atrophy, ankylosing spondylitis, lumbar spinal stenosis, spina bifida, spinal tumors, osteoporosis and cauda equina syndrome.

<span class="mw-page-title-main">Spinal stenosis</span> Disease of the bony spine that results in narrowing of the spinal canal

Spinal stenosis is an abnormal narrowing of the spinal canal or neural foramen that results in pressure on the spinal cord or nerve roots. Symptoms may include pain, numbness, or weakness in the arms or legs. Symptoms are typically gradual in onset and improve with leaning forward. Severe symptoms may include loss of bladder control, loss of bowel control, or sexual dysfunction.

Cervical spondylotic myelopathy (CSM) is a disorder characterised by the age-related deterioration of the cervical spinal cord. Also called spondylotic radiculomyelopathy (SRM), it is a neurological disorder related to the spinal cord and nerve roots. The severity of CSM is most commonly associated with factors including age, location and extent of spinal cord compression.
