Lumbar Fusion Surgery in Turkey

Lumbar fusion is surgery that connects two or more bones (vertebrae) in the lower spine. Connecting the bones prevents movement between them. Preventing movement in that spot may reduce the pain it causes.

During the operation, the surgeon places bone or a bone-like material in the space between two vertebrae. Metal plates, screws or rods may hold the vertebrae in place. The bone then heals (this is called fusion), and the treated section becomes one solid unit. The procedure is also known as lumbar spine stabilization.

This article covers lumbar fusion surgery in Turkey: when it is considered, what the evidence says, how the main techniques differ by surgical approach, and what the risks and recovery involve. It is major surgery and does not suit everyone. Many cases of back pain are treated without surgery first. The surgeon decides whether a patient is a suitable candidate after examination and imaging.

Do you need fusion at all? Non-surgical treatment comes first

Lower back pain is common. In many cases it improves over time with gradual activity, physical therapy, lifestyle changes and some medications. According to England’s Evidence Based Interventions programme, fusion is not recommended for mechanical back pain, meaning pain caused by strain and stress on the spine. It may not improve symptoms, and it may sometimes make them worse.

Other medical sources agree that results are mixed when the cause of pain is unclear. In these cases fusion often does not outperform non-surgical treatment.

For spondylolisthesis (a vertebra slipping forward), patients are usually referred to a surgeon when other treatments have not helped. These include avoiding painful activities, pain relievers, steroid injections and physical therapy.

A herniated disc on its own usually does not need fusion. If your condition looks more like a disc pressing on a nerve, read about discectomy in Turkey and herniated disc treatment in Turkey.

When is fusion considered, and what does the evidence say?

The evidence differs from one condition to another and does not give one answer for everyone. Many published comparisons are small or include mixed groups of patients. For that reason, the absence of a significant difference means a difference was not shown. It does not prove that two options are equivalent.

Spondylolisthesis with stenosis: a matter of debate

Spondylolisthesis is the forward slipping of one vertebra over the one below it. Spinal stenosis is a narrowing of the space through which the nerves pass. The two can occur together, and the narrowing can press on the nerves.

Two randomized trials published in 2016 compared decompression alone with decompression plus fusion. Their results differed:

• The Swedish trial included 247 patients aged 50 to 80 with stenosis at one or two levels (a level is two vertebrae and the disc between them). Some also had spondylolisthesis. There was no significant difference between the groups in function or walking ability after two years, or after five years. Hospital stay was relatively longer with fusion, blood loss was greater, and cost was higher. The main analysis excluded patients who did not receive the treatment they were assigned.
• The US SLIP trial included only 66 patients with grade I spondylolisthesis and stenosis, without instability on dynamic X-rays. Physical quality-of-life improvement was slightly greater with fusion, and reoperation was relatively less frequent (14% versus 34% with decompression alone). But the difference was borderline in statistical terms. About 30% of patients were lost to follow-up at four years, and the significant difference disappeared after adjusting for baseline differences between the groups.

Importantly, SLIP excluded patients with clear instability. Mobile spondylolisthesis with mechanical back pain is generally accepted as a reason for fusion. So the debate mainly concerns stable slippage.

In both approaches, a later operation may be needed. Reoperation rates were similar between the groups in the Swedish trial and relatively lower with fusion in SLIP. And with fusion, new problems can develop in the neighboring vertebrae, as described in the risks section below.

In short, it cannot be said that fusion is always required or never required. This is one of the most important things to discuss with your surgeon. For details on stenosis options, see spinal stenosis treatment in Turkey.

Stenosis without instability or deformity: decompression is often enough

The main goal of stenosis surgery is to restore space for the nerves. US guidelines (AANS/CNS) recommend against adding fusion when there is no deformity or instability. But this is a weak, grade C recommendation based on limited evidence.

The same guidelines also note that extensive decompression can itself cause instability, and that fusion may improve the outcome in that situation, based on limited evidence. So a surgeon may decide to add fusion even when there was no slippage before the operation.

In many cases, laminectomy surgery in Turkey or something similar may be enough.

Chronic pain from disc degeneration: the weakest evidence

For chronic back pain from disc degeneration at one or two levels, without stenosis or slippage, trials and reviews have been inconsistent:

• Trials that compared fusion with an intensive rehabilitation program including cognitive behavioral elements did not find a clear advantage for fusion. In one, the difference was small and its clinical importance was hard to judge. Another found no significant difference.
• A Swedish trial found a relative advantage for fusion over conventional non-surgical care. But its comparison group was not well defined, and some patients crossed over between groups.
• Systematic reviews concluded that the evidence does not settle the question, and that the pooled difference favoring fusion was not statistically significant and of unclear clinical importance.
• US guidelines consider fusion or a cognitive rehabilitation program as alternatives for patients who did not respond to conservative care, and acknowledge that the studies do not support a strong recommendation.

For this reason, the decision in this group should be made carefully, and only after a good trial of rehabilitation.

Other conditions

Medical sources list other reasons for fusion, including spinal deformities such as scoliosis, severe instability, fractures, tumors, infection and some previous surgeries. Each needs an individual assessment broader than this article can cover.

Who may not be suited to fusion?

Fusion does not suit every patient, and some conditions make certain techniques inappropriate:

• Active infection in the area.
• Severe scarring around the nerves or inflammation of the arachnoid membranes, which complicate access from the back.
• Osteoporosis, which is listed among the contraindications to some techniques.
• Previous abdominal surgery or severe blood vessel disease, which restrict access from the front.
• Smoking and diabetes, which increase the risk that the bone will not heal.

Your surgeon determines these after examination and imaging.

Preparation and tests before surgery

Preparation usually includes:

• Reviewing your medical history and medications. You may be asked to stop some medications before surgery.
• Blood tests and an assessment of your general health for anesthesia.
• Imaging with X-rays, magnetic resonance imaging (MRI), and sometimes computed tomography (CT).
• Stopping smoking, because nicotine slows bone and wound healing and raises the risk of infection.
• Arranging for someone to help you during your first days at home.

How is the operation performed?

The operation is performed under general anesthesia. Its duration varies with the number of levels and the technique. Some sources mention roughly two to three hours for a TLIF operation.

In general, the surgeon follows these steps:

1. Reaching the spine from the back, the side or the abdomen, depending on the technique.
2. Relieving pressure on the nerves if needed.
3. Preparing the disc and vertebrae, and placing the bone material (and sometimes a cage) between them.
4. Fixing the vertebrae with screws and rods or plates until the bone heals.
5. Closing the incision and moving you to the recovery room.

The bone may come from your pelvis, from a tissue bank, or from artificial materials, depending on the surgeon’s decision.

Lumbar fusion techniques: from which direction does the surgeon approach?

Interbody fusion means removing the damaged disc and placing a cage and bone material in its place. Its techniques differ in the surgical approach. There are also other fusion techniques not covered in this section, including posterolateral fusion.

There is not enough evidence to show that one approach is superior to another in bone healing or clinical results. Many available comparisons are observational or small, so differences between them should be read as relative and with caution. The choice often depends on what the surgeon is experienced in, and on the level of the problem and the patient’s anatomy.

PLIF: Posterior Lumbar Interbody Fusion

The surgeon approaches directly through the back and gently moves the nerve roots aside to reach the disc. Its advantages include that most surgeons are trained in it, and that it gives a good view of the nerves and allows decompression at the same time. Its limits include stretching of the back muscles and possible irritation of the nerve roots. Some analyses suggest relatively more complications than with TLIF.

TLIF: Transforaminal Lumbar Interbody Fusion

The surgeon approaches from the back at an angle and opens the foramen (the opening where the nerve exits) on one side. This relatively reduces nerve retraction compared with PLIF.

A review of randomized trials compared TLIF with other techniques pooled together. It found similar clinical results and complications, with relatively lower bone healing at one year and no difference at two years. But the number of patients in some comparisons (such as ALIF) was very small, and the review included only single-level surgeries. So the lack of a difference here does not mean the techniques are equivalent. TLIF’s limits include that restoring the spine’s natural curve (lordosis) may be relatively harder than with ALIF, and that osteoporosis may restrict its use.

ALIF: Anterior Lumbar Interbody Fusion

The surgeon approaches through the abdomen to the front of the spine. According to the authors of one review, and not to direct comparative trials, this technique allows relatively wider cleaning of the disc, a larger cage, and easier restoration of the spine’s curve, without passing through the spinal canal.

It is usually suited to the two lower levels: between the fourth and fifth lumbar vertebrae (L4–L5), and between the fifth lumbar vertebra and the first sacral vertebra (L5–S1). Higher levels carry relatively higher risks and require the help of a vascular surgeon.

Its risks are specific to entering through the abdomen: injury to blood vessels, hernia at the incision site, vein thrombosis, and ejaculation problems in men. Previous abdominal surgery and severe vascular disease limit its use.

LLIF and OLIF: lateral and oblique fusion

• LLIF (Lateral Lumbar Interbody Fusion), also known as XLIF, approaches through the side, passing through the psoas muscle. It generally suits levels from the upper lumbar spine down to L4–L5, and is not suitable at L5–S1 because of the pelvic bone. Its risks include injury to the lumbar nerve plexus and the muscle itself.
• OLIF (Oblique Lumbar Interbody Fusion) approaches at an oblique angle in front of the muscle, avoiding splitting it. Its risks include sympathetic nerve disturbance and blood vessel injury. Data on it are more limited.
• Neither is usually suitable for severe central stenosis or high-grade slippage.

Small incision versus open surgery

Some of these techniques can be performed through smaller incisions (minimally invasive), which may reduce blood loss and hospital stay in some patients. But the evidence has not yet shown a difference in patient outcomes compared with open surgery, and this needs confirmation in randomized trials.

How is the technique chosen?

The surgeon weighs the level of the problem, the type of disease (slippage, stenosis or disc degeneration), the number of levels, the anatomy of blood vessels and nerves, previous surgeries, and his or her own experience with the technique. Ask your surgeon why a particular technique was chosen for your case and what the alternatives are.

Recovery

Recovery varies with the condition, the technique and the number of levels. According to recognized medical sources, with approximate figures that differ between them:

• Hospital stay is roughly two to four days.
• Short daily walks are encouraged from the start, while avoiding bending, twisting, heavy lifting and driving in the first weeks.
• Bone healing takes several months, and full recovery may take up to a year.
• Structured physical therapy may begin after about 6 weeks to 3 months, depending on the surgeon.
• A back brace may be recommended for a period.

Signs that call for contacting your doctor:

• Fever or chills.
• Change in color, swelling or fluid from the wound.
• Swelling or pain in the leg.
• Shortness of breath.

Signs that call for urgent medical help:

• Loss of control over urination or bowel movements, or loss of sensation when passing urine or stool.
• Numbness between the thighs or around the anus and genitals.
• New or worsening weakness or numbness in the legs.

These symptoms may indicate severe pressure on the nerves at the bottom of the spine (cauda equina syndrome) and need immediate assessment.

Risks and complications

Fusion is major surgery. Its risks include the following. I do not give percentages here because they vary widely between studies and techniques.

• General: infection, poor wound healing, bleeding, blood clots in the veins that may travel to the lungs, injury to nerves or blood vessels, pain at the bone graft site, and return of symptoms. Protocols for preventing clots vary between centers.
• Nonunion (pseudarthrosis): the bone does not heal sufficiently, and another operation may be needed. Contributing factors include smoking, diabetes, older age, and moving too early before healing begins.
• Adjacent segment disease: when vertebrae in one area do not move, the vertebrae above and below carry more stress. They may break down faster, and later surgery may be needed. Rates vary widely depending on the definition and the length of follow-up, and it remains unsettled whether the cause is the surgery or the natural progression of spinal degeneration. The length of the fused section is one associated factor.
• Hardware problems: a screw loosening or breaking, or the cage shifting.
• Dural tear (a tear in the membrane around the nerves) with leakage of spinal fluid.
• Risks specific to each technique: described in their sections above.

Pain may persist after fusion. Fusion does not treat arthritis and does not prevent future back pain. And later surgery may be needed in cases under either path, as noted above.

Factors that affect the result

• The cause of pain and an accurate diagnosis: the more clearly the source is identified, the relatively higher the chance of benefit.
• Quitting smoking and controlling diabetes.
• Age, bone condition and general health.
• The number of fused levels.
• The surgeon’s experience with the specific technique and how well it fits your condition.
• Following instructions after surgery, including physical therapy and follow-up.

Cost of lumbar fusion surgery in Turkey

O9 Medical estimates the initial cost of lumbar fusion surgery in Turkey at roughly $5,000 to $13,000 USD. This is an indicative estimate, not a final quote or a commitment.

The final price is affected by several factors, including the number of fused levels, the surgical technique, the type of hospital, the length of stay, the type of implants, the need for additional procedures such as nerve decompression, and any unexpected tests or complications. Price alone does not indicate the quality of care.

For this reason the price is set after reviewing your reports and imaging. When you receive any quote, ask clearly what it includes: the surgery, implants, stay, tests and follow-up, and what may be charged separately.

Having the operation in Turkey with O9 Medical

Some patients consider having surgery in Turkey, for reasons that differ from patient to patient. But the medical decision, meaning whether you need fusion at all and by which technique, is made by the surgeon after examining you and reviewing your reports, not by the location of treatment.

O9 Medical helps you understand your options and arrange the steps of communication. This usually starts by sending your reports and imaging for review, then arranging a consultation with a spine surgeon. When choosing a doctor or center, you can look at the page on orthopedic and joint surgery hospitals in Turkey and the spine surgery page.

What cannot be guaranteed: No one can guarantee pain relief or a particular result after fusion. Results vary from patient to patient depending on the diagnosis, the technique, general health and commitment to recovery. What O9 Medical offers is help with understanding and organization, not a promise of a treatment result.

If you are weighing your options, you can send your reports and imaging to O9 Medical through the contact channels on the website for review, with no obligation to have surgery.

Questions to ask your surgeon before deciding

• What exact diagnosis justifies fusion in my case? What are the non-surgical alternatives?
• Would decompression alone be enough?
• Which technique do you propose, and why? What is your experience with it?
• How many levels will be fused?
• What are the main risks in my case, and might I need another operation later?
• What is the expected hospital stay, and what is the follow-up plan before I travel?
• What should I do if complications appear after I return to my country, and whom should I contact?
• When can I fly? (Your surgeon and anesthesiologist answer this based on your condition.)
