Spinal Fusion in Seomyeon, Busan

What is spinal fusion?

Spinal fusion (척추 유합술) stops movement at a painful or unstable segment of the spine. The surgeon decompresses any trapped nerves, removes the disc if needed, places a cage or bone graft between vertebrae, and usually secures the level with screws and rods. Over months, the bones grow together into a single solid unit. Fusion is a bigger operation than decompression alone, so it is reserved for situations where stability or alignment needs correcting.

Who is it for?

Spondylolisthesis (one vertebra slipping on another) with nerve symptoms
Spinal instability seen on flexion and extension X-rays
Scoliosis or kyphosis deformities causing pain or progressive imbalance
Some spinal fractures, infections or tumours
Cervical disc disease treated with ACDF

Fusion for back pain alone, without instability or nerve compression, has less predictable results and is approached cautiously.

What happens at the hospital

Planning: MRI, CT and standing X-rays, sometimes bone density testing.
Pre-op workup: blood tests, ECG and review of blood thinners and diabetes control.
Surgery: decompression, cage and graft insertion, and screw fixation, often with real-time X-ray or navigation.
Ward care: pain control, early walking (often within 1–2 days), and wound care.
Discharge plan: activity limits, brace use if prescribed, and follow-up X-rays.

Recovery and aftercare

Walking is encouraged daily from early on. Lifting, bending and twisting are limited for several weeks to months. Most people return to desk work in about 4–6 weeks and heavier work later. Bone fusion takes 6–12 months; smoking and uncontrolled diabetes greatly reduce fusion rates. Rehab focusing on core endurance usually starts after initial healing.

Risks and side effects

Risks include infection, bleeding, nerve injury, dural tear, blood clots, failure of the bones to fuse (pseudarthrosis), screw loosening and, over years, extra stress on adjacent levels (adjacent segment disease). Osteoporosis increases hardware complications, so bone health matters.

Choosing a clinic for spinal fusion in Seomyeon

Ask what exactly is unstable or deformed, and see the evidence on your images.
Ask whether decompression alone or a less extensive option is possible.
Ask which fusion approach (PLIF, TLIF, OLIF) is planned and why.
Ask about bone density testing if you are older or have osteoporosis risk.
Seek a second opinion for multi-level fusion; reputable surgeons welcome this.

Planning your stay

Fusion requires a hospital stay and weeks of limited activity, so it is best planned well in advance. For follow-up visits, Seomyeon's location on Lines 1 and 2 keeps travel short.

How long does it take to recover from spinal fusion?

Most people walk within a day or two, return to desk work around 4–6 weeks, and resume most activities by 3–6 months. Full bone fusion takes about 6–12 months.

Will I lose flexibility after spinal fusion?

Fusing one or two lower-back levels usually causes little noticeable loss of overall movement. Longer fusions limit bending more. Your surgeon can explain the expected effect.

Is spinal fusion covered by National Health Insurance?

Medically necessary spinal fusion is generally covered by NHI for enrolled patients, with co-payments. Some implants, navigation or room upgrades can be non-covered, so request an itemised estimate.

Should I get a second opinion before spinal fusion?

Yes, especially for fusion of multiple levels or when back pain is the main symptom. A second opinion helps confirm that fusion is needed and that the planned approach is appropriate.

What is adjacent segment disease?

It is wear at the spinal levels next to a fusion, which may develop years later. Not everyone develops symptoms, but some people eventually need further treatment.
