Lumbar Facet Joint Pain
Lumbar Facet Arthropathy / Lumbar Facet Syndrome
What is Lumbar Facet Joint Pain?
Lumbar facet joint pain is also commonly referred to as lumbar facet joint syndrome, facet joint disease, facet joint sprain, but mostly it is a pain caused by a facet joint injury.
Your facet joints are also known as zygapophyseal, apophyseal, or Z-joints. They are synovial joints between the vertebrae of your spine. There are two facet joints (left and right) in each spinal motion segment.
Each section of your spine has facet joints. You may hear them referred to as your cervical facet joints (neck), thoracic facet joints (mid-back) and lumbar facet joints (low back). Biomechanically, the function of each pair of facet joints is to guide and limit the movement of that spinal motion segment. Facet joint pain is one of the most common causes of neck pain, back pain and thoracic spine pain.
What Causes Lumbar Facet Joint Pain?
Facet joint motion can be disturbed by injury. Joint action can stiffen – known as hypomobility. Alternatively, joint movement can become excessive – known as hypermobility.
What Causes Lumbar Facet Joint Hypomobility?
Facet joint hypomobility can be caused by:
- locked facet joint,
- facet joint arthritis,
- degenerative facet joint osteophytes (bone spurs),
- joint capsule scarring, thickening or shortening, or
- protective muscle spasm.
In other words, a facet joint can stiffen due to a slow degeneration or due to uncontrolled motion, which is where your local muscle strength is essential to stabilise and control your facet joints.
What Causes Lumbar Facet Joint Hypermobility?
Trauma usually causes hypermobility. Examples include:
- Overstretched ligaments, or
- Any disease that destroys the joints, e.g. Rheumatoid Arthritis.
What Causes a Locked Lumbar Facet Joint?
Simple movements such as a mild twist, awkward movement, or just doing something your body didn’t expect (such as tripping) can lock a facet joint. In most cases, this is due to your facet joints motion exceeding your muscle control.
If you have previously suffered an injury or have local muscle weakness supporting your facet joints, it is even easier to lock a facet joint repeatedly.
What are the Symptoms of a Locked Lumbar Facet Joint?
Pain is one of the first symptoms a patient will notice with a facet joint injury. A back facet joint injury will cause low back pain and potentially pain referred to your buttock or thigh.
When a facet joint locks, you may not be able to move in the direction away from where it’s locked. For example, if the joint is locked in a flexed forward position, you will probably have difficulty arching backwards. The opposite also occurs. In acute phases, muscle spasms will attempt to protect the injured facet joint.
The initial injury can sometimes occur days or occasionally weeks earlier. Your body will attempt to compensate for the locked joint by the neighbouring joints moving more than they usually would. This excessive movement can often cause pain on the opposite side of the locked facet joint and may potentially lead to other conditions such as sciatica or arm pain. Most commonly, you will notice decreased movement and pain or difficulty stretching.
People who have this problem recurrently are said to have facet joint syndrome. The most common cause of facet joint syndrome is weak stability muscles that fail to control your spine’s movement.
How is a Facet Joint Injury Diagnosed?
A lumbar facet joint injury is the most accurate diagnosis via a hands-on examination from your spinal physiotherapist. Using their professional skills, they will confirm the specific facet joint problem and whether it is locked, stiff or unstable. X-rays, MRIs, and CT scans are used to identify arthritic changes and fractures but cannot detect a locked facet joint.
Please consult your physiotherapist for specific advice regarding your facet joint pain management.
Lumbar Facet Joint Syndrome Treatment
The treatment for a locked facet joint is relatively simple. Your physiotherapist will quickly detect which facet joint is locked. Then proceed to unlock it. Usually, your physiotherapist will open a locked facet joint using a painless joint releasing technique.
The next step is to regain full motion and commence strengthening or other exercises to prevent a future, recurrence. Everyone is slightly different, so your treatment will vary depending on what deficits your physiotherapist has found during your examination.
Unstable Facet Joint Treatment
Unstable or hypermobile facet joints need to be treated entirely differently to a locked facet joint. The fact that the joint already moves excessively would suggest that further joint loosening is unlikely to assist a hypermobile facet joint.
These patients respond better to muscle control and stabilization program. You physiotherapist will guide you.
Please check with your physiotherapist or doctor for their professional opinion.
What Results Can You Expect?
Physiotherapy will provide the majority of facet joint pain patients with complete relief. (Hu et al. 2006). Locked facet joints will usually start improving immediately post-unlocking. How they progress beyond that, depend on what other concomitant factors are present. How long has the joint been locked? What caused the locking? What adjacent joint motion there is available?
Based on your physiotherapist’s examination, they will be able to provide you with more strict guidelines. Facet joint instability will take longer to rehabilitate since they require time and practice for your muscle strengthening to occur. Once again, please check with your treating physiotherapist for their professional opinion and treatment plan.
Other Treatment Options
Massage can be an excellent form of muscle spasm relief to allow your facet joint spasm to release.
Localized acupuncture or dry needling techniques can provide localized muscle spasm and facet pain relief. Ask your physiotherapist for more advice.
Facet Joint Injections
Facet joint injections may confirm a diagnosis and provide short-term (a week or two) relief. Researchers have found that facet joint injections are less effective than patients who exercise in the long-term. (Mayer et al. 2004)
Radiofrequency in chronic cases which do not respond to physiotherapy treatment is an option. Radiofrequency cauterizes the nerve, providing pain relief for some time. The downside is that the pain returns typically when the nerve regrows within a few months.
Every case of facet joint pain is different. Please check with your physiotherapist for their professional opinion on what treatment plan is best for you.
Common Lower Back Pain Causes
The following conditions may cause lower back pain.
- Back Cramps
- Back Muscle Pain
- Core Stability Deficiency
- DOMS - Delayed Onset Muscle Soreness
- Side Strain
- Back Stress Fracture
- Scheuermann's Disease
- Spinal Stenosis
- Stress Fracture Spine (Cricket Bowlers)
Back Joint Injuries
Youth Spinal Pain
Teenager Neck & Back Pain
Teenagers can be particularly vulnerable to back pain, mainly due to a combination of high flexibility and low muscle strength and posture control.
The competitive athlete and most individuals who exercise regularly or maintain fitness and core stability control are less prone to spine injury and problems due to the strength and flexibility of supporting structures. Luckily, issues involving the lower lumbar spine are rare in athletes and account for less than 10% of sports-related injuries. Injuries do occur in contact sports and with repetitive strain sports. Your physiotherapist can assist in the resolution of any deficits in this area.
Sports such as gymnastics, cricket fast bowlers, and tennis have a higher incidence of associated lumbar spine problems related to repetitive twisting and hyper-bending motions.
Spondylolisthesis is a significant concern and needs to be appropriately treated by a physiotherapist with a particular interest in these types of injuries. Luckily, most injuries are minor, self-limited, and respond quickly to physiotherapy treatment.
