Understanding Scoliosis Surgery: What to Expect Before, During, and After Treatment
Scoliosis can be a frustrating condition that causes a great deal of pain and discomfort. Doctors work to present as many quality solutions for scoliosis
Back pain is one of the most common reasons patients seek neurosurgical or spine care. It may present as sudden discomfort, persistent aching, sharp shooting pain, or dull stiffness, and can range from short-term (acute) to long-lasting (chronic). While many patients improve with conservative treatment, selected individuals may benefit from epidural steroid injection when pain persists or imaging findings do not clearly correlate with clinical symptoms.
At the Spine Center, Vejthani International Hospital, back pain management follows a structured, evidence-based approach that emphasizes accurate diagnosis, individualized treatment planning, and long-term functional outcomes.
Clinical care is provided by experienced spine specialists, including neurosurgeons who focus on comprehensive evaluation and minimally invasive pain management options when appropriate.
Understanding Back Pain and Nerve-Related Symptoms
Back pain may result from various spinal conditions, including:
- Degeneration of intervertebral discs
- Disc herniation
- Spinal stenosis
- Failed back surgery syndrome
- Nerve root inflammation
Symptoms may include localized lower back pain, pain radiating down the leg (radicular pain or sciatica), numbness, tingling, or weakness. Acute pain may last days to weeks, while chronic pain can persist for more than six months and significantly affect quality of life.
Initial treatment typically involves medications, rest, physical therapy, and rehabilitation. When these measures fail to provide adequate relief or when imaging findings are inconclusive, interventional pain procedures may be considered.
Diagnostic Evaluation Before Treatment
Accurate diagnosis begins with:
- Detailed medical history
- Neurological physical examination
- Imaging studies such as X-ray, CT scan, or MRI of the lumbosacral spine
If imaging does not clearly explain the patient’s symptoms, or when multiple factors contribute to pain, targeted injection therapy may serve both diagnostic and therapeutic purposes.
What Is Epidural Steroid Injection?
Epidural steroid injection is a minimally invasive procedure in which a corticosteroid combined with a local anesthetic is delivered into the epidural space near irritated nerve roots.
The goal is to:
- Reduce inflammation around spinal nerves
- Decrease pain signals
- Improve mobility and daily function
In selected cases, a selective nerve root block may be performed, targeting a specific affected nerve to help identify the pain source while providing symptom relief.
Modern techniques allow precise needle placement through a single entry point, enabling both diagnostic confirmation and pain management during the same procedure.
Common Indications
This treatment may be considered for patients with:
- Radicular pain (shooting pain down the arm or leg)
- Disc herniation with or without nerve symptoms
- Spinal stenosis
- Persistent back pain when imaging findings are unclear
- Pain in patients who are not suitable candidates for surgery
Each case is evaluated individually to determine whether injection therapy is appropriate.
Contraindications and Safety Considerations
Absolute Contraindications
- Active infection (local or systemic)
- Significant bleeding disorders
- Known severe allergy to anesthetics, steroids, or contrast agents
Relative Contraindications
- Use of certain blood-thinning medications (which may need temporary discontinuation)
- Poorly controlled diabetes
- Active gastrointestinal bleeding
- Heart failure or uncontrolled hypertension
An in-depth medical review is performed before any procedure to ensure patient safety.
Expected Outcomes and Recovery
Pain relief varies between individuals. Some patients experience significant improvement within days, while others may notice gradual changes over several weeks. The procedure does not cure underlying structural problems but may reduce inflammation and provide a window for rehabilitation and functional recovery.
Injection therapy is often combined with physical therapy and lifestyle modification as part of a comprehensive treatment plan.
Why Specialist Care Matters
Back pain can have complex and overlapping causes. At the Spine Center, Vejthani International Hospital, patients benefit from multidisciplinary care involving neurosurgeons, spine specialists, and rehabilitation professionals.
Treatment decisions are based on:
- Clinical symptoms
- Imaging findings
- Overall health status
- Patient goals and functional needs
This personalized approach helps ensure that minimally invasive procedures are used appropriately and effectively.
FAQ
Is epidural steroid injection a surgical procedure?
No. It is a minimally invasive, image-guided injection performed without open surgery.
Does the injection permanently eliminate back pain?
Results vary. The procedure aims to reduce inflammation and pain but does not correct structural spinal problems.
How long does pain relief last?
Relief may last from weeks to months, depending on the underlying condition and individual response.
Can this treatment replace surgery?
In some patients, it may delay or avoid surgery. However, surgical treatment may still be required in severe cases.
