Sciatica is a neurological condition that mainly arises due to problems in the sciatic nerve. The sciatic nerve is believed to be the largest nerve originating from the spinal nerves L4 to S3. It extends downward from the lower spine into the back of each leg (thighs) right down to the foot. The sciatic nerve acts as a connecting link between the spinal cord and the foot and the leg muscles. People with sciatica often experience a tingling sensation along with a shooting pain radiates downwards from the lower back (mostly the lumbar region) to the back of one of the legs. Some may also experience the sciatic pain down both the legs (rare).

Types of Sciatic Pain:

Sciatica that affects a person can be of two types depending on the severity of the associated symptoms

Acute sciatic pain: In this case, a person experiences a sudden radiating pain which often heals by itself within a week or two. More than often, the pain is triggered by an injury to the spinal joints, nerves, or the disc.
Chronic sciatic pain: This is a more serious condition where the pain may linger for long, often more than three months. The chronic sciatic pain may affect a person with severe Arthritis and nerve injury and damage.
Symptoms associated with Sciatica:

One of the characteristic symptoms of Sciatica is a shooting pain that radiates from the lower back (often the lumbar) to the back of one (or both) of the legs.
In some, the sciatic pain may result in weakness and a tingling sensation down the affected leg.
A person with sciatica may find it difficult to move his/her foot and legs (restricts their movement).
Some people may experience a shooting pain even while they are in a sitting position. In some others, the pain may be at its worst when a person is in a standing position.
Sciatica can also trigger a hip pain.
What triggers sciatica and the associated symptoms?

The disc is a protective shield that prevents any damage or injury to the vertebrae. A degenerative disc problem can interfere with the normal functioning of the disc triggering sciatica.
Spondylolisthesis: In Spondylolisthesis, also known as a Slip Disc, a bone (mostly in the lumbar region) slips over the bone which is located just below it. People with prolonged and untreated spondylolisthesis are often known to suffer from sciatica.
The sciatic pain can also affect a woman during her pregnancy.
Lumbar spinal stenosis: This condition is is characterized by the spinal canal narrowing down in the lumbar region. Lumbar spinal stenosis exerts pressure on the sciatic nerve, giving rise to sciatica.
A muscular strain or spasm in the buttocks can also be a contributing factor.
Proper management and prevention for sciatica are possible. One should be alert and consult a doctor in case they experience the associated symptoms or any discomfort.

Sciatica Pain - What Can Trigger It?

Sciatica pain can be mild to intense. Many with lumbar herniated disc and sciatica often wonder whether or not they require a surgery. Needless to say, it is never an easy decision. But the good news is that micro discectomy surgery has a higher rate of success when it comes to relieving sciatica pain. When compared to many other options, this one is relatively minimally invasive. It doesn t alter the structure of the spine permanently since it works by removing a small portion of the disc, which has herniated or extruded out of the disc.

When your sciatica pain stems from lumbar disc herniation, a small open surgery with the help of magnification is the prevalently opted surgical approach. On the other hand, a laminectomy is done when the bone or disc pinching the nerve root is required to be removed.

When should you consider undergoing surgery for sciatica?
Typically, neurosurgeons recommend considering surgery for sciatica in a host of situations which include the following:

Severe pain in the leg lingering for more than six weeks, which mainly affects one side of the leg or buttock
Intense pain in the low back and buttock, which continues through the course of the sciatic nerve andextends to the lower leg and even foot. This pain can be described as sharp and searing rather than a dull thud.
When pain has not alleviated even after non-surgical treatments that may include non-steroidal anti-inflammatory drugs (NSAIDs),oral steroids, injections, manual manipulations, and physical therapy
When the patient is not able to take part in the day to day activities due to intense lower back pain and the symptoms tend to become severe during movements like sneeze and cough.
When the symptoms are continuing to worsen, thereby indicating nerve damage, particularly when the progressive signs have their root in neurological issues
It is important to note here that surgical intervention may only be needed when the patient experiences progressive weakness in the lower portion of the body or sudden loss of bladder or bowel movement, which may stem from cauda equina syndrome. Two surgeries, namely lumbar laminectomy and microdiscectomy are performed on the basis of the cause as well as the duration of the sciatica pain.
In some cases, the symptoms are unique on the basis of the underlying causes of sciatica. For instance, trying to bend the body backward or walking a longer distance than normal may trigger unbearable symptoms. On the other hand, when the affected individual tries to bend the body forward, it can lead to symptoms stemming from the lumbar herniated disc.
In case sciatica occurs after an accident, injury or trauma, or if it happens in tandem with other symptoms, then it requires an immediate medical attention.
Thus, choosing to go for a surgery depends on several factors that only your doctor can assess and decide upon.

Sciatica - When Do You Have To Go For Surgery?

The intervertebral discs are made-up of two concentric layers, the inner gel-like Nucleus Pulposus and the outer fibrous Annulus fibrosus. As a result of advancing age, the nucleus loses fluid, volume and resiliency and the entire disc structure becomes more susceptible to trauma and compression. This condition is called as degeneration of the disc. The disc then is highly vulnerable to tears and as these occur, the inner nucleus pulposus protrudes through the fibrous layer, producing a bulge in the intervertebral disc. This condition is named as herniated disc. This can then cause compression to the spinal cord or the emerging nerve roots and lead to associated problems of Sciatica radiating pain from back to legs in the distribution of the nerve. Other symptoms could be a weakness, tingling or numbness in the areas corresponding to the affected nerve. Sometimes bladder compromise is also present, which is made evident for urine retention and this need to be taken care as an emergency.
Excessive weight, bad postures, undue movements, improper weight lifting and other kinds of traumas may weaken the intervertebral discs. When this occurs the pulpous nucleus will bulge against the annulus, or even be squeezed through it (extruded disc).

The first steps to deal with a herniated or prolapsed lumbar disc are conservative. These include rest, analgesic and anti-inflammatory medication and in some cases physical therapy. At this point, it is convenient to have some plain X-rays done, in search of some indirect evidence of the disc problem, as well as of degenerative changes on the spine.

If in a few days these measures have failed, the diagnosis has to be confirmed by means of examinations that give better detail over the troubled area, as the MRI, CT which will show the disc, the space behind it and in the first case, the nerves. In some instances, the EMG (electromyography) is also of great value, as this will show the functionality of the nerves and muscles.

Once the diagnosis has been confirmed, one of the best alternatives existing today is the Ozone Discolysis as the results obtained are excellent and practically has no complications. This novel treatment avoids the use of surgery in 80% of those who needed it. In most patients left with painkillers as the only treatment, the symptoms eventually disappear, only that this could take weeks to months. Ozone speeds up these developments, see the same result in a few weeks. The problem has to be seen and approached integrally and frequently the combination of therapies has to be used, most frequently physiotherapy. Also, it has to be known that those who had a herniated disc have 10 times more chances of having another herniation than the rest of the population.

If despite the ozone therapy the symptoms persist, Drill Discectomy/ Laser Discectomy are good alternatives before open surgery (Discectomy) which has to be contemplated in those true emergencies, as mentioned above, this is possibly the first choice.

Once the conservative treatment fails:

Early aggressive treatment plan of pain has to be implemented to prevent peripherally induced CNS changes that may intensify or prolong pain making it a complex pain syndrome. Only 5% of total LBP patients would need surgery & 20% of discal rupture or herniation would need surgery. Nonoperative treatment is sufficient in most of the patients, although patient selection is important even then.

Depending upon the diagnosis one can perform & combine properly selected percutaneous fluoroscopic guided procedures with time spacing depending upon pt`s pathology & response to treatment.

Using precision diagnostic & therapeutic blocks in chronic LBP, isolated facet joint pain in 40%, discogenic pain in 25% (95% in L4-5&L5S1), segmental dural or nerve root pain in 14% & sacroiliac joint pain in 15% of the patients. This article describes successful interventions of these common causes of LBP after conservative treatment has failed.

LESI: Lumbar Epidural Steroid Injection

Indicated in   Acute radicular pain due to irritation or inflammation.

Symptomatic herniated disc with failed conservative therapy
Acute exacerbation of discogenic pain or pain of spinal stenosis
Neoplastic infiltration of roots
Epidural fibrosis
Chronic LBP with acute radicular symptoms
Epidural- lumbar injection
ESI Treatment Plan

Compared to interlaminar approach better results are found with a transforaminal approach where drugs (steroid+ LA/saline +/- hyalase) are injected into anterior epidural space & neural foramen area where herniated disc or offending nociceptors are located. Whereas in interlaminar approach most of drug is deposited in posterior epidural space.Drugs are injected total 6-10 ml at lumbar, 3-6 ml at cervical & 20+ ml, if caudal approach is selected. Lumbar ESI is performed close to the level of radiculopathy, often using paramedian approach to target the lateral aspect of the epidural space on involved side. Cervical epidural is performed at C7-T1 level.

SNRB- Selective Nerve Root Block 

Fluoroscopically performed it is a good diagnostic & therapeutic procedure for radiculopathy pain if

There is minimal or no radiological finding.
Multilevel imaging abnormalities
Equivocal neurological examination finding or discrepancy between clinical & radiological signs
Postop patient with unexplainable or recurrent pain
Combined canal & lateral recess stenosis.
To find out the pathological dermatome for more invasive procedures, if needed
Intradiscal Procedures 

Provocative Discography - Coupled with CT

A diagnostic procedure & prognostic indicator for surgical outcome is necessary for the evaluation of patients with suspected discogenic pain, its ability to reproduce pain(even with normal radiological finding), to determine type of disc herniation /tear, finding surgical options & in assessing previously operated spines.

Percutaneous Disc Decompression (PDD)

After diagnosing the level of painful offending disc various percutaneous intradiscal procedures can be employed

Ozone Discolysis: Ozone Discectomy a revolutionary least invasive safe & effective alternative to spine surgery is the treatment of choice for prolapsed disc (PIVD) done under local anaesthesia in a daycare setting. This procedure is ideally suited for cervical & lumbar disc herniation with radiculopathy. The total cost of the procedure is much less than that of surgical discectomy. All these facts have made this procedure very popular at European countries. It is also gaining popularity in our country due to high success rate, less invasiveness, fewer chances of recurrences, remarkably fewer side effects meaning high safety profile, short hospital stay, no postoperative discomfort or morbidity and low cost.

Dekompressor: A mechanical percutaneous nucleosome cuts & drills out the disc material somewhat like morcirator debulking the disc reducing nerve compression.

Epidural Adhenolysis or Percutaneous Decompressive Neuroplasty for Epidural Fibrosis or Adhesions in Failed Back Surgery Syndrome (FBSS)

A catheter is inserted in epidural space via caudal/ interlaminar/ transforaminal approach. After epidurography testing volumetric irrigation with normal saline/ L.A./ hyalase/ steroids/ hypertonic saline in different combinations is then performed along with mechanical adenolysis with spring loaded or stellated catheters or under direct vision with epiduroscope.

Procedures That Can Help Treat Slip Disc & Sciatica!

The term Sciatica is used to describe leg pain, tingling, numbness or weakness that travels down the low back via the sciatic nerve to the back of leg. Sciatic nerve arises from each side of lower spine and passes deep in the buttock along the back of thigh and legs. The pain of Sciatica may be irregular/ infrequent or persistent causing severe agony to the patients. The pain of Sciatica may be confined to low back or hips or may extend up to toes. The pain of Sciatica can be excruciating and "not relieved by painkillers".

What causes Sciatica?

Pain in Sciatica is due to irritation or pinching of Sciatic nerve within the spine. This occurs most commonly due to prolapsed intervertebral disc (slip disc) causing nerve compression resulting in pain.

Is surgery the only treatment for Sciatica?

Most patients can be managed with medication/exercises. So surgery is not the only way out. Patients who have severe pain can also benefit from "Epidural Steroid Injection". This treatment has proven to be effective in avoiding spine surgery in such patients.

What is Epidural Steroid Injection?

Epidural Steroid Injection is a procedure done by a Specialist (Interventional Pain) in an Operation Theatre using X-Ray (Image Intensifier) to locate exact level of injection. A drug mixture consisting of Steroid with Local Anaesthetic is injected at the epidural space of affected nerve root. The steroid washes away inflammatory mediators from the epidural space which decreases the pain. Steroid also decreases the inflammatory response of body to the prolapsed disc. As a result the pain arising from nerve inflammation is decreased. This is a day care procedure i.e. the patients are discharged the same day.

How is the possibility of surgery ruled out?

Epidural Steroid Injection is a proven, safe and an effective treatment that works on the concept of Interventional pain management - to provide relief from persistent and chronic pain of Sciatica. Generally, a single injection is sufficient to relieve patients of the pain. The procedure can be repeated for a maximum 3 times in a year, depending on the patient's response. With effective pain relief, surgery is negated.

Non-Surgical Treatment For Sciatica

The sciatic nerve spreads down the spine till the legs. The pain in this nerve can feel like sparks running down your leg (by and large only each one in turn) or cause pain in the lower back. Anything that puts weight on or aggravates this nerve can cause pain that shoots down the back of one butt cheek or thigh. The amount of pain can increase gradually. Sciatica may feel like a gentle ache, a sharp sensation or extreme uneasiness. Sciatica can bring feelings of shivering, numbness and weakness.

Sitting, standing up, coughing, sneezing, lifting, or straining for a very long time, might aggravate pain. Now and then, individuals experience numbness or shivering in the leg, too. Some of the most regular symptoms of sciatic pain include:

1. Lower back pain
2. Pain in the back or leg when sitting
3. Hip pain
4. Burning sensation in the leg
5. Numbness or trouble moving the leg or foot
6. Continuous pain on one side of the back
7. Shooting pain that makes it hard to stand up properly

The most common causes of sciatic pain include:

1. Lumbar spinal stenosis (narrowing of the spinal channel in the lower back)
2. Degenerative disk sickness (breakdown of discs, which go about as pads between the vertebrae)
3. Spondylolisthesis (a condition in which one vertebra slips over another)
4. Pregnancy
5. Muscle spasms

Some of the most effective exercises for sciatic pain relief are as follows:

1. Pigeon Pose is a typical yoga posture. It attempts to open the hips. There are various types of this stretch. The first is the leaning back pigeon posture. If you are beginning your treatment, you have to attempt the leaning back posture first.

2. While on the back, raise your right leg up to a right point and hold it with both hands behind the thigh and lock your fingers. Take your left leg and touch your lower leg against the knee. Hold the position for a minute.

3. Sit on the floor with your legs stretched straight before you. At that point twist your right leg, putting your lower right leg on top of the left knee.

Bend forward and incline your abdominal area toward your thigh. Hold for 15 to 30 seconds and after that switch sides.

4. Kneel down on the floor on all fours. Get your right leg and bring it forward so that your lower leg is on the ground. Your right foot has to be ahead your right knee while your right knee stays to one side. Stretch the left leg out the distance behind you on the floor, with the top of the foot on the ground and toes pointing backwards.

5. Lie on your back with your legs facing outward and your feet flexed upward.

Wrap your hands around your knee and delicately pull your right leg over your body toward your left shoulder. Hold it there for 30 seconds and afterward push your knee so your leg comes back to its initial position.

Sciatica Pain and Ways to Deal With It

While it may be obvious that no form of pain is welcome, it can be said that pain which is felt on account of being affected by sciatica is especially unwelcome. Taking that into due account, the good news is that physiotherapy can go a long way in helping by improving this sort of pain.

The longest nerve in the whole human body is the sciatic nerve, so it can be expected that when there is trouble with this nerve, the pain would be pretty significant. The leg pain which is caused to a person when this nerve happens to be getting pinched is known as sciatica.

There is a range of treatments when it comes to how something as painful as sciatica is to be solved. Now, while it is true that a solution such as making sure there is an amount of bed rest which is sufficient is very important, to say the very least, it is often the case that the person with sciatica would like his or her recovery to be hastened.

In order to make sure that this is the case, physiotherapy is quite useful. There are various forms of physiotherapy which can be made use of, and the decision as to which sort of physiotherapy a person would be best suited to would obviously be part of the subjective assessment of the person by a practitioner who is well qualified and experienced.

Some of the solutions when it comes to physiotherapy being used in order to treat sciatica are quite innovative, to say the very least. For example, there is physiotherapy instrument mobilisation, which is also known as PIM. What this entails is that a mechanical spring-loaded instrument is used in the process which serves the purpose of mobilising the spinal cord of a person along with his or her peripheral joints.

One form of physiotherapy oriented treatment which is used to address the issue of sciatica is real-time ultrasound physiotherapy. It can be said that this is not close to as cutting edge as physiotherapy instrument mobilisation is but it does serve as a rather dependable and useful way to battle sciatic pain. This form of physiotherapy makes use of ultrasound technology to analyse how the muscles function and then using that as a basis to create a list of physiotherapy exercises to be done by the person who is having sciatica. Rather than medicines, physiotherapy improves sciatica by getting a person to use oneself!
