At a glance
Microdiscectomy is a minimally invasive spine surgery that removes the small piece of a herniated disc pressing on a spinal nerve root.
Each disc in your spine acts like a cushion between two vertebrae (the bones of your backbone). When the soft inner core of a disc bulges or ruptures through its outer wall, it can squeeze a nearby nerve. That pressure causes the sharp, shooting pain, numbness, or weakness that travels down the leg or arm. In a microdiscectomy, the surgeon uses a microscope and tiny instruments through a small cut in the back to remove only the fragment that is pushing on the nerve, leaving as much of the disc intact as possible.
Medical Condition
Microdiscectomy is considered when a herniated disc causes nerve pain that has not improved after weeks of non-surgical treatment such as physiotherapy, pain medication, or steroid injections.
- Lumbar disc herniation (a slipped disc in the lower back) causing sciatica, the shooting pain that runs from the lower back down one leg
- Cervical disc herniation (a slipped disc in the neck) pressing on a nerve root and causing arm pain or weakness, when approached through a modified technique
- Foot drop or hand weakness that is getting worse because of ongoing nerve compression
- Loss of bladder or bowel control linked to nerve compression, which is treated as a surgical emergency
- Severe, disabling nerve pain that does not respond to at least six weeks of conservative treatment
This procedure is not suitable for everyone. Your surgeon will advise against it in certain situations.
- Back pain caused mainly by the disc space itself rather than by nerve compression, because removing the fragment will not relieve that type of pain
- Multiple levels of disc disease that need a larger reconstruction
- Significant spinal instability (abnormal movement between vertebrae) that requires fusion surgery instead
- Active infection at or near the surgical site
- Bleeding disorders or medical conditions that make anaesthesia very high risk
Risks & Complications
Microdiscectomy is generally considered a safe procedure with a low complication rate, but like any surgery it carries recognised risks.
- Temporary increase in nerve pain or numbness in the days after surgery, as the irritated nerve settles
- Dural tear: a small accidental nick in the membrane (dura) surrounding the spinal cord, which usually heals with a short period of bed rest
- Disc reherniation: the same or a nearby disc fragment pushing on the nerve again, which may require a second procedure
- Infection at the wound site or, more rarely, deeper infection around the spine (discitis)
- Bleeding or formation of a haematoma (a blood clot) pressing on the nerve after surgery
- Nerve root injury causing persistent weakness or numbness in the leg or foot
- Anaesthesia-related reactions such as nausea, allergic response, or, very rarely, cardiovascular events
- Incomplete relief of symptoms if the nerve was compressed for a long time before surgery
Preparation & Procedure
Your surgical team will give you specific instructions in the days before your operation. The steps below reflect what most hospitals require.
Stop eating solid food at least six hours before surgery and stop drinking clear fluids at least two hours before, unless your anaesthetist says otherwise. Blood thinners such as aspirin or anticoagulants are usually stopped several days in advance; your doctor will set the exact timing. Smoking slows wound healing and raises the risk of complications, so surgeons typically ask patients to stop for at least two weeks before the procedure. Alcohol is also best avoided in the days leading up to surgery.
Standard pre-operative tests usually include blood tests to check clotting and general health, an EKG (electrocardiogram, a recording of heart activity) if you are older or have heart conditions, and imaging of your spine. Your surgeon will review the MRI (magnetic resonance imaging) or CT scan that identified the herniated disc before confirming the plan.
On the day of surgery, the typical sequence of events is as follows.
- You arrive at the hospital and are admitted to the pre-operative area, where nursing staff check your vital signs and confirm your identity and consent
- An intravenous (IV) line is placed in your arm for fluids and medication
- The anaesthetist reviews your history and administers general anaesthesia, though some centres use spinal anaesthesia (a numbing injection into the spine) for selected patients
- You are positioned face-down on the operating table with padding to protect pressure points
- The surgeon makes a small cut, usually around two to three centimetres, over the affected disc level in your lower back
- Muscles are gently moved aside using a retractor (a tool that holds tissue out of the way) rather than being cut
- Using an operating microscope for magnification, the surgeon removes a small portion of bone or ligament to expose the nerve and the disc fragment
- The herniated fragment is carefully removed with fine instruments
- The wound is closed in layers and covered with a sterile dressing
- You are moved to the recovery room while the anaesthesia wears off
Aftercare
Most patients go home the same day or the morning after surgery, though recovery milestones depend on individual health, how long the nerve was compressed, and whether any complications occurred.
- You will be monitored in a recovery area for pain control, wound condition, and nerve function before discharge
- Walking is usually encouraged within a few hours of the procedure, as gentle movement supports healing and prevents blood clots
- Sitting for long periods and bending or twisting sharply at the waist are typically restricted for the first few weeks
- Heavy lifting is usually avoided for four to six weeks; your surgeon will set a specific limit based on your job and physical condition
- The wound should be kept dry until the stitches are removed or dissolve, usually within ten to fourteen days; showering instructions vary by hospital
- Pain is managed with oral pain medication in the early days; you will be told when to taper off
- Physiotherapy (physical rehabilitation exercises) is usually started within a few weeks to rebuild core strength and protect the spine
- A follow-up appointment is typically scheduled within two to six weeks so the surgeon can check nerve recovery and imaging if needed
- Return to desk work often happens within two to four weeks; physically demanding jobs may require six to twelve weeks off
- Driving is restricted until you can react quickly without pain, which your doctor will assess at your follow-up visit
Cost & What Determines It
The total price of a microdiscectomy varies widely from one country to another and even between hospitals in the same city, because the final bill is built from many separate components that each carry their own price tag.
- Complexity of the case: a single-level herniation at a straightforward angle costs less than a case involving scar tissue from a previous spine surgery or an unusually deep disc level
- Hospital class and country: a private university hospital in a high-income country charges differently from an accredited private hospital in a medical travel destination
- Type of anaesthesia: general anaesthesia typically adds more to the bill than spinal anaesthesia
- Operating theatre and microscope time: longer procedures with more preparation time increase the surgical fee
- Length of hospital stay: a same-day discharge is cheaper than an overnight or multi-night admission
- Implants or instruments: in rare cases where a small bone graft or fixation device is used alongside the discectomy, the implant cost is added separately
- Post-operative imaging: an MRI or CT scan done after surgery to confirm the result is usually billed as an extra
- Physiotherapy: inpatient rehabilitation sessions add to the total if included in the hospital stay
- Medication: take-home pain medication and any specialised drugs prescribed during admission are often itemised separately
Many hospitals offer a surgery package that bundles the surgeon's fee, anaesthesia, one night of accommodation, standard nursing care, and basic post-operative medication into a single price. Items that are commonly billed outside the package include pre-admission blood tests and imaging, any specialised implants used during surgery, extended physiotherapy, and the follow-up consultation after discharge.
For Indonesian patients, BPJS Kesehatan and most domestic private insurance plans do not cover treatment performed abroad. This means most patients who travel for microdiscectomy pay entirely out of pocket, or through an international health insurance plan that explicitly covers overseas surgery. Before booking flights or accommodation, ask the hospital abroad for a written cost estimate that lists each component separately. That document lets you compare hospitals fairly and avoids unexpected charges on arrival.
Frequently Asked Questions
How long does a microdiscectomy operation take?
Most microdiscectomy procedures take between one and two hours. The exact time depends on how much disc material needs to be removed and whether scar tissue from a previous surgery is present. Your surgeon will give you a more specific estimate after reviewing your scans.
How much does microdiscectomy cost?
The cost varies depending on several factors specific to this procedure, including the hospital class you choose, the complexity of your disc herniation (the bulging disc pressing on your nerve), whether one or more spinal levels need treatment, and the length of your hospital stay. The most reliable way to get a real number is to request a written estimate directly from the hospital.
How long is recovery after microdiscectomy, and when can I go back to work?
Most people can walk the day after surgery and return to a desk job within two to six weeks. Physical work or heavy lifting usually requires a longer break of around six to twelve weeks, depending on how well healing progresses. Your surgeon will guide you based on how you recover at each follow-up check.
What warning signs should I watch for after microdiscectomy surgery?
Contact your surgical team promptly if you notice new weakness or numbness in your legs, loss of bladder or bowel control, fever, increasing pain around the wound, or any redness and swelling at the incision site. Loss of bladder or bowel control in particular needs urgent attention, as it can signal pressure on the nerves at the base of the spine. Most recoveries go smoothly, but recognising these signs early gives the best chance of a quick response.
