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?

Sciatica pain arises from the sciatic nerve which is the single largest nerve in our body. It consists of individual nerve roots, which branching out from the lower back of the spine to the back of each leg and combining together forms the sciatic nerve. The origination of the sciatic pain lies in the lower back of the body and radiates down the buttock to the sciatic nerve.

Causes of the sciatica pain

Arthritis: If an individual is diagnosed with arthritis, then he or she can expect a throbbing pain or numbness down till the leg.
Herniated disc: Another cause could be a herniated disc in the lower back of the body.
Spondylosis: Spondylosis in the lower back would also be a reason for the development of the sciatica pain.
PIVD/DISC bulge
Other causes are a spinal injury, diseased degenerative disc, infection on and around the lower back. The pain would worsen, if an individual is in an occupation where he or she has to stand or sit for hours at length. The lifting of heavy things would strain the sciatic nerves as well.

How to identify sciatica pain?
Sciatica pain varies from infrequent to a constant throbbing down the lower back. So initially it is difficult to detect whether it is sciatic pain or not. But when the constant pain in the lower back leads right down till the toes and foot, it is really time for an individual to get in touch with a doctor. The pain can give a burning sensation almost searing making it difficult for the person to stand up or walk properly. Along with the pain, one can feel fatigued. An involvement of the spinal cord is rare in the sciatic pain but is possible.

Treatment for sciatica pain
Sciatica can be treated in both surgical and non-surgical way. Surgical treatment is rare as sciatica tends to respond well with non-surgical treatments. If the pain continues for over a month despite treatment, surgical treatment will be considered. The non-surgical pain treatment would include physical exercises and oral medications along with natural treatment.

Medications: Painkiller medications prescribed by the doctor can be used to reduce sciatica. Medicines like aspirin, non-steroidal or oral steroids can help reduce the pain.
Steroid injection: Epidural steroid injection acts faster as it is injected in the affected area, thus providing relief from the pain quickly.
Exercise: Early morning exercises can be quite helpful.
Percutaneous Endoscopic Discectomy: The surgical treatment of Percutaneous endoscopic disc dissectomy constitutes a large part of interventional pain physicians and it has evolved considerably in terms of surgical technique and instrumentation. Percutaneous endoscopic discectomy is a relatively new technique for removing lumbar disc herniation. It involves using an endoscope to visualize the disc removal. The discectomy is performed through a posterolateral approach using specially developed instruments. The advantage of percutaneous endoscopic discectomy is that the disc is approached posterolaterally through the triangle of Kambin without the need for bone or facet resection thus preserving spinal stability. The procedure is day care and is done under local anaesthesia.

Sciatica Pain - 5 Ways You Can Treat It!

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

Ever faced a nagging low back ache that just won't quit? You could be dealing with sciatica. Sciatica or sciatic nerve pain is not a diagnosis in itself, but is a symptom of a deeper problem. Conditions that trigger sciatica include degenerative discs, spinal stenosis, a herniated disc in the lumbar region or   spondylolisthesis. Whether your sciatica pain is persistent or sporadic, it can make routine tasks difficult to perform. The good news is that there are a number of remedies to ease this pain and improve the health of your spine.

1. Hot and cold therapy: Sciatic pain that extends down to the thighs can be relieved by alternating between a heat pack and an ice pack. Each pack can be applied for about 20 minutes at a stretch every two hours. However, this does not treat the sciatic nerve itself.

2. Pain medications and steroid injections: Over the counter pain medication like ibuprofen or muscle relaxants can help alleviate pain and reduce inflammation. In chronic cases, epidural steroid injections may also be prescribed to address the inflammation and pain. Pain relief provided by medication and steroid injections can last for a few days or a few months depending on the person.

3. Yoga: Sciatica patients looking for long term relief often turn towards alternative forms of treatment like yoga. Yoga helps strengthen muscles, increases flexibility and improves posture. This is more beneficial towards preventing sciatica problems from arising than treating ongoing sciatic pain. When practicing yoga with a sciatica problem, it is very important to understand your body's limitations and not over extend your back muscles.

4. Massage: A massage that treats sciatic pain is very different from the usual massage you may get at a spa. A massage to relieve sciatic pain involves putting pressure on the inflamed part of the back and the piriformis muscle. This is the muscle that sits over the sciatic nerve and triggers sciatic pain. In most cases, 3 to 4 massage sessions at intervals of 7 to 10 days can have effective results on sciatic pain.

5. Physical therapy: Sciatica patients often find the slightest movement extremely painful. While lying in a bad is tempting, it can actually worsen the pain. Exercise increases blood flow to the spine and helps flush out toxins. Going for a walk, light aerobics or swimming are ideal ways for a sciatica patient to exercise.

6. Chiropractic manipulation: This involves realigning the spinal column and is an effective way of treating underlying conditions that trigger sciatic pain. These spinal adjustments should only be performed by licensed chiropractors or osteopathic physicians.

Treatments for Sciatica Pain

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!

Sciatica refers to the pain one experiences due to the irritation or compression of nerve roots contributing to formation of Sciatic nerve. The sciatic nerve is the longest and widest nerve in the body, running from the lower back, down to the back of each leg. The pain can occur in the lower back and spread to the hips, buttocks and leg. Sciatica generally affects one side of the body. There are numerous causes of irritation of the sciatic nerve and sciatica.
 
Some of them are:
 
1. Spinal Stenosis
The narrowing of the spinal canal caused by natural wear and tear of the vertebrae (individual bones in the spine protecting underlying nerves) of the spine is known as spinal stenosis. The narrowing may put pressure on the roots of the sciatic nerve, causing pain.
 
2. Herniated Disc
A disc is made up of cartilage and acts as a cushion between vertebrae, allowing flexibility of the spine. A herniated or slipped disc occurs when a disc is temporarily pushed out of place, putting pressure on the sciatic nerve.
 
3. Spondylolisthesis
It is a condition where one of the lower vertebrae slips forward over another. This also causes a collapse of the disc space between both, causing the nerve to get pinched. This may cause sciatica.
 
4. Piriformis Syndrome
Piriformis is a muscle found deep inside the buttocks, which connects the lower spine to the upper thighbone, running directly over the sciatic nerve. Spasming of this muscle can pressurize the sciatic nerve, triggering symptoms of sciatica.

5. Sacroilitis
Sacroillac joints are the place where the lower spine meets the pelvis and inflammation of one or both of these joints causes sacroilitis. This can give rise to symptoms of sciatica as it causes pain in the lower back, buttocks and legs.
 
6. Spinal tumors
Very rarely, tumors growing inside or along the spine may put pressure on the sciatic nerve.
 
7. Infection or injury
Muscle inflammation, infections, fractures or any other spinal injury may lead to irritation or compression of the sciatic nerve.
 
8. Pregnancy
Pregnant women may suffer from sciatica due to weight gain, expansion of the uterus or increased fluid retention or other changes occurring in the body, which put pressure on the sciatic nerve.
 
9. Other causes
Osteoarthritis and fractures caused by osteoporosis may also affect the sciatic nerve, producing symptoms of sciatica.
