Facet Joints.png

Facet syndrome is an articular disorder related to the lumbar facet joints and their innervations, and produces both local and radiating pain. Ghormley was the first who characterized the ‘facet syndrome’ by back and/or leg pain, as a result from mechanical irritation of a lower lumbar zygapophysial joints. This is more then 20 years ago, but the facet joint has been increasingly recognized as an important cause of low back pain.[1]

Excessive rotation, extension, or flexion of the spine (repeated overuse) can result in degenerative changes to the cartilage of the joint and may involve degenerative changes to other structures including the intervertebral disc. [2](Level of evidence: 5) Strain of the lumbar facet joint (FJ) is highest at end-range extension.[3](Level of evidence: 1B) Additionally, with a reduction of disc height, FJ mechanical loads will increase, which can also leads to degeneration of the FJs. [3](Level of evidence: 2A)

55% of facet syndrome cases occur in cervical vertebrae, and 31% in lumbar. This includes all the structures that are a part of the facet joint such as the fibrous capsule, synovial membrane, hyaline cartilage and bone.[4]

Neck pain due to cervical facet joint involvement is known as cervical facet syndrome and low back pain due to lumbar facet joint involvement is known as lumbar facet syndrome.

Clinically Relevant Anatomy[edit | edit source]

The facet joints are joints in the posterior aspect of the spine. In each spinal motion segment there are two facet joints. Although these joints are most commonly called facet joints, they are more properly termed zygapophyseal joints (abbreviated as Z-joints; also commonly spelled as "zygapophysial joints"), a term derived from the Greek roots zygos, meaning yoke or bridge, and physis, meaning outgrowth. This “bridging of outgrowths” is most easily seen from a lateral view, where the Z-joint bridges adjoin the vertebrae. The term facet joint is a misnomer because the joint occurs between adjoining zygapophyseal processes, rather than facets, which are the articular cartilage lining small joints in the body (eg, phalanges, costotransverse and costovertebral joints). This joint is also sometimes referred to as the apophyseal joint or the posterior intervertebral joint.[5][6][7]


Further the detailed anatomy and clinical anatomy can be learned from here .

Epidemiology /Etiology[edit | edit source]

According to Binder D et al.(level2A), it has been estimated that facet joint pathology is a contributory factor in 15–52% of patients with chronic low back pain. But the prevalence of isolated facet joint pain may be as low as 4%. More important is the presence of facet joint arthrosis in different age groups. In a study from Eubanks et al.(level 2B) there was a prevalence rates of facet arthrosis on 647 cadaveric lumbar spines. 57 percent of samples between 20 and 29 years of age and 93% of the samples 40-49 years of age had evidence of facet arthrosis. By the age of 60, 100% of the samples showed prominent facet arthrosis.
The highest prevalence and moreover, the greatest severity of arthrosis, were found at L4–L5. [8]Facet joint syndrome is more common in the elderly since changes at the joints develop with aging.(Level of evidence 1B)

The hypothesis that disc degeneration and disc narrowing play a meaningful role in facet joint dysfunction via increased loading and subsequent osteoarthritis , is often cited, but has yet to be supported by sufficient evidence.
In rare cases, facet joint pain can occur secondary to a traumatic event, but more commonly, it is the result of repetitive stress and/or cumulative low-level trauma. Data from cadaveric studies have shown that anatomical changes occur more rapidly during sustained flexion than with repetitive movements. Although the studies provides a theoretical model of degeneration, cadavers cannot experience pain and the viscoelastic materials may have altered characteristics.
In the upper lumbar spine, the greatest amount of joint displacement and strain is associated with lateral-flexion or side-bending in the first three pairs of facet joints (L1-L2; L2-L3; L3-L4). The two lowest levels(L4-L5; L5-S1) experience the greatest strain during forward flexion. The resultant inflammation causes the joint to swell, leading to stretching of the capsule and subsequent pain generation. The swelling can also irritate the nearby spinal nerves, resulting in spasm of the deep postural paraspinal muscles (ex. M. Multifidus). [9](level of evidence 1A)
Predisposing factors for lumbar facet joint pain are spondylolisthesis, spondylolysis, degenerative disc disease and advanced age.[9] (level of evidence 1A)

Characteristics/Clinical Presentation[edit | edit source]

Lumbar region.png

Zygapophyseal joint pain is felt locally as a unilateral back pain, which when severe can spread down the entire limb. The source of pain must be confirmed by clinical examination.
The joint capsule is more likely to generate pain than the articular cartilage or the synovium. All of the lumbar facet joints are capable of producing pain that can refer to the groin (this is more common with lower facet joint pathology).[10](level of evidence 1B)

Cervical facet syndrome includes following symptoms:

  • Axial neck pain (rarely radiating past the shoulders), most common unilaterally
  • Pain with and/or limitation of extension and rotation
  • Tenderness upon palpation
  • radiating pain locally or into the shoulders or upper back, and rarely radiate in the front or down an arm or into the fingers as a herniated disc might.

Lumbar facet syndrome can be characterised by following symptoms:[9](level of evidence 1A)

  • Pain or tenderness in lower back.
  • Local tenderness/stiffness alongside the spine in the lower back.
  • Pain, stiffness or difficulty with certain movements (such as standing up straight or getting up from a chair.
  • Pain upon hyperextension
  • Referred pain from upper lumbar facet joints can extend into the flank, hip and upper lateral thigh
  • Referred pain from lower lumbar facet joints can penetrate deep into the thigh, laterally and/or posteriorly
  • L4-L5 and L5-S1 facet joints can refer pain extending into the distal lateral leg, and in rare instances to the foot[10](level of evidence 1B)


Additionally, facet joint syndrome is more common in the elderly since changes at the joints develop with aging. [1]
Acute episodes of lumbar and cervical facet joint pain are typically intermittent, generally unpredictable, and occur a few times per month or per year. Typically, there will be greater aggravation of symptoms with lumbar extension than lumbar flexion. In lumbar cases, standing may be somewhat limited but sitting and riding in a car are most provocative. Recurrent painful episodes can be frequent and quite unpredictable in both timing and extent. Improper diagnosis can result in patients that are left with the notion that this is a psychosomatic problem.[2] (level of evidence: 5)

Osteoarthritis is only one of many inflammatory processes that affect the facet joint. Other inflammatory conditions include rheumatoid arthritis, ankylosing spondylitis, reactive arthritis, synovial impingement, meniscoid entrapment, chondromalacia facetae, pseudogout, synovial inflammation, villonodular synovitis, and acute chronic infection.[10](level of evidence 1B) Intrafacetal synovial cysts can be a source of pain because of distension and pressure on adjacent pain-generating structures, calcification, and asymmetrical facet hypertrophy.[9](level of evidence 1A)

Differential Diagnosis
[edit | edit source]

Much has been written about the diagnosis and treatment of lumbar zygapophyseal joint pain. A review of the relevant literature found conflicting evidence in support of a relationship between radiographic facet joint abnormalities and facet-mediated pain. This may partly be due to the poor reliability of the lumbar “facet joint syndrome” diagnosis given to patients presenting with primary lower back pain complaints. The“pseudoradicular” referral patterns of the lumbar facet joints may mimic the pain felt from a herniated disc and may make differentiating between the two conditions difficult.[3]


What’s the difference between facet joint syndrome and Lumbar Spondylosis:
Facet joint syndrome is not the same as spondylosis. The difference between those two is that spondylosis is a degeneration of the vertebrae. If we speak of facet joint syndrome, there is a degeneration of the facet joints which are the posterior aspect of the spine.


Examples of a possible differential diagnosis:
Cervical spine:[4]

  • Cervical disc injuries
  • Cervical discogenic pain syndrome
  • Cervical radiculopathy
  • Cervical spine sprain/strain injuries


Lumbar spine:[5]

Diagnostic Procedures[edit | edit source]

Facet joint syndrome cannot be reliably clinically diagnosed (Jackson RP2 1992). The most used systems to diagnose this syndrome are X-ray, computed tomography (CT) scan of the spine or a magnetic resonance imaging (MRI) scan. Plain radiography does not provide information in establishing the diagnosis of facet joint syndrome, but it may help with the evaluation of the degree of degeneration. Once degeneration is visible on plain radiography it has already reached an advanced stage.
The working diagnosis of facet pain, based on history and clinical examination, may be confirmed by performing a diagnostic block. A positive indication is when the patient experiences a 50% pain reduction after a block has been performed. It involves injecting a medicine into or near the nerves that supply the facet joint. If the pain is not relieved by the injection, it is unlikely that the facet joint is the source of the pain. If these injections help to reduce the pain, we can suggest that the pain comes from the facet joint.

Although no single sign or symptom is diagnostic, Jackson et al demonstrated that the combination of the following 7 factors was significantly correlated with pain relief from an intra-articular facet joint injection:

- Older age
- Previous history of LBP
- Normal gait
- Maximal pain with extension from a fully flexed position
- The absence of leg pain
- The absence of muscle spasm
- The absence of exacerbation with a Valsalva maneuver [3]

Outcome Measures[edit | edit source]

Discomfort FJS:
- the parameter finger-floor distance
- lumbar spine rotation
- Schober's index (10 cm distance along lumbar spine, difference in cm after flexion of lumbar spine)
- 10 point visual analog scale (VAS) [6](Level of evidence: 1B)

Examination[edit | edit source]

Inspection
Inspection should include an evaluation of paraspinal muscle fullness or asymmetry, increase or decrease in lumbar lordosis, muscle atrophy, or posture asymmetry.
Patients with chronic facet syndrome may have flattening of the lumbar lordotic curves and rotation or lateral bending at the sacroiliac joint or thoracolumbar area.

Palpation
The examiner should palpate along the paravertebral regions and directly over the transverse processes because the facet joints are not truly palpable. This is performed in an attempt to localize and reproduce any point tenderness, which is usually present with facet joint–mediated pain.
In some cases, facet joint–mediated pain may radiate to the gluteal or posterior thigh regions.

Range of motion
Range of motion should be assessed through flexion, extension, lateral bending, and rotation
With facet joint–mediated LBP, pain is often increased with hyperextension or rotation of the lumbar spine, and it might be either focal or radiating.

Flexibility
Inflexibility of the pelvic musculature can directly impact the mechanics of the lumbosacral spine.
With facet joint pathology, the clinician may find an abnormal pelvic tilt and rotation of the hip secondary to tight hamstrings, hip rotators, and the quadratus, but these findings are nonspecific and can be found in patients with other causes of LBP.

Sensory examination
Sensory examination (ie, light touch and pinprick in a dermatomal distribution) findings are usually normal in persons with facet joint pathology.

Muscle stretch reflexes
Patients with facet joint–mediated LBP usually have normal muscle stretch reflexes. Radicular findings are usually absent unless the patient has nerve root impingement from bony overgrowth or a synovial cyst.
Side-to-side asymmetry should lead one to consider possible nerve root impingement.

Muscle strength
Manual muscle testing is important to determine whether weakness is present and whether the distribution of weakness corresponds to a single root, multiple roots, or a peripheral nerve or plexus.
Typically, manual muscle testing results are normal in persons with facet joint pathology; however, subtle weakness of the muscles of the pelvic girdle may contribute to pelvic tilt abnormalities. This subtle weakness may be appreciated with trunk, pelvic, and lower-extremity extension asymmetry.

Medical Management
[edit | edit source]

  • Pharmacological therapy commonly consists of the prescription of muscle relaxants prescribed by a physician to treat acute back pains   secondary to facet joint syndrome
  • Over the counter pharmacological therapy includes: nonsteroidal anti-inflammatory drugs(NSAIDS) and acetaminophen as a first line   intervention to help decrease of LBP. Little evidence supports one particular drug over another.[3] [8]
  • Standard treatment for facet joint syndrome pain include intra-articular steroid injections and radiofrequency ablation of the medial branches innervating the joints. Yet there is much controversy in scientific articles related to this standard treatment.

Cohen S. P. et al. (2007) investigated several publications about the effectiveness of intra-articular steroid injections and radiofrequency ablation of the medial branches. In uncontrolled studies of people that have never been diagnosed for facet joint syndrome, the long-term relief of back pain after intra-articular steroid injection varies from 18% to 63%. In controlled trials, the results are disputable. In the largest study, investigators report no significant difference between patients who received combined local anesthetic (LA) and steroids versus saline injections.

Cohen S. P. et al. also verified that radiofrequency ablation of the medial branches innervating the joints, is an effective treatment for facet joint syndrome. Unfortunately, there aren’t enough studies that follow the same protocol, to make a conclusion about it. For example, the placement of the electrodes plays a very crucial role in processing the results.
There is also controversy about the long term effect of radiofrequency ablation. Further research should confirm whether radiofrequency ablation is an effective treatment in people with facet joint syndrome.[9] [9][10]

Ribeiro LH et al. (2013) investigated the effectiveness of facet joint injections versus systemic steroid pharmacologic use in patients with the diagnosis of facet joint syndrome. The term facet joint syndrome used to define back pain originating from the facet joints. Treatment mainly consist of a conservative approach, although more aggressive interventions, including intra-articular injections and medial branch nerve blocks used to manage facet-mediated pain. Several studies have evaluated the effectiveness of these interventions, however, the results of facet joint injection, are conflicting. We concluded, based on the previou study, that both treatments were effective, with a slight superiority of the intra-articular injection of steroids over intramuscular injection.[1](level of evidence: 2B)

Physical Therapy Management
[edit | edit source]

Physical Therapy:
Although numerous studies have examined conservative management for low back pain, at the present time, we couldn’t find published investigations of conservative management specifically targeted to facet joint pain. However, most experts would agree that the general principles for treatment of nonspecific benign low back pain may be applied.[8]


The initial treatment for acute facet joint pain is focused on:

  • education
  • maintenance of positions that provide comfort
  • reducing lumbar lordosis
  • relative rest
  • pain relief
  • exercises


Patient education includes explaining the problem or their associated impairment to the patient, without making them anxious. It includes pain education mostly therefore a diplomatic approach is recommended in order to prevent the patient from catastrophizing. During the therapy, it’s also important that the therapist gives advice/instructions or cues about the patient’s posture and placement of his body to make corrections during everyday activities. The patient must learn to take postures that will not provoke or exacerbate the symptoms.[2]


Therefore it is important to reduce excessive lumbar lordosis with exercise because excessive lordosis increases loading on the posterior aspect of the spine, including the z-joints. To achieve this, the patient should be taught pelvic maneuvers to reduce the degree of lumbar lordosis. These pelvic tilt exercises can be performed in multiple positions such as sitting, standing with knees bent or straight legs. [7]

Bed rest beyond 2 days isn’t recommended as it can have undesirable effects on bones, connective tissues, muscles and the cardiovascular system.
The patient is encouraged to limit activity on days when the symptoms are not tolerable, but should never be completely inactive. Therapist must strive to influence the patient to be as active as possible.[2]


Another goal is pain relief.

Bronfort G. et al. (1996) studied the relative efficacy of three different treatments for chronic low back pain. They comprised followed combinations: spinal manipulative therapy (SMT) combined with trunk strengthening exercises (TSE) vs. SMT combined with trunk stretching exercises and SMT combined with TSE vs. non-steroidal anti-inflammatory drug (NSAID) therapy combined with TSE. During 11 weeks (5 weeks under supervising and 6 weeks alone) they examined: patient-rated low back pain, disability and functional health status. Their conclusion was that each of the three therapeutic regimens was associated with similar and clinically important improvements. For the management of facet joint syndrome, trunk exercise in combination with SMT or NSAID therapy seemed to be beneficial and worthwhile.[3](Level of evidence: A2)
Spinal manipulation is being used for both short- and long-term pain relief.[7]
Other scientific sources recommend treating facet joint syndrome with heat, cryotherapy and mobilizations. These techniques appear to have a relaxing effect on the muscles. As the muscles relax, the nociceptive information will decrease. While these techniques have clear advantages, they generally only attain a temporary pain relief as they are often not a final solution to treat facet joint syndrome.


Gerard A. Malanga et al. (2008) argue that once the painful symptoms are controlled, stretching and strengthening exercises can be initiated.[2]For the stretch, the focus should be on the muscles that create excessive anterior tilt of the pelvis. Stretching should not be not limited to just these muscles because all the muscles articulating to the lumbar spine and pelvic girdle may be imbalanced, and regular stretching can help restore productive mechanics to the lumbar spine and pelvis. Therefore, stretching programs should also include the hamstrings, quadriceps, hip abductors, gluteals, and abdominals. Stretching through dynamic postural motions (eg, yoga postures) can be especially helpful because the motions can restore balance to the muscles of the lumbar spine and pelvic girdle.[7] These exercises are eventually incorporated into a more extensive rehabilitation program, which includes spine stabilization exercises The objective of these exercises is to teach the patient how to find and maintain a neutral spine throughout everyday activities.[2]


In the final phase of the rehabilitation, eccentric muscle strengthening exercises and dynamic exercises are added to the program. These are to be performed in a functional manner and in functional planes. All exercises were performed in the treatment room under the supervision of a physical therapist with technical knowledge. The therapist put each patient into the appropriate position to achieve the correct posture and muscle contraction. An important focus of the exercise therapy should be on stabilization therapy.They are aimed to strengthen the deep lumbar stabilizing muscles: the transversus abdominis, lumbar multifidi, and internal obliques. A series of 16 exercises should be performed in the same order, as described by Moon et al (2013). Before each exercise, the physical therapist gave detailed verbal explanation and visual instructions (pictures), regarding the start and end positions. All exercises were conducted according to the following specific principles: breathe in and out, gently and slowly draw in your lower abdomen below your umbilicus without moving your upper stomach, back or pelvis"; resulting in a situation referred to as hollowing. Subjects practiced "hollowing" with a therapist providing verbal instruction and tactile feedback until they were able to perform the maneuver in a satisfactory manner. In addition, a "bulging" of the multifidus muscle should have been felt by the therapist when the fingers were placed on either side of the spinous processes of the L4 and L5 vertebrae, directly over the belly of this muscle. These feedback techniques provided by precise palpitation of the appropriate muscles, ensure effective muscle activation.[10](level of evidence 1B)
