Lumbar microdiscectomy is a minimally invasive operation that removes the small piece of herniated disc pressing on a nerve in the lower back. It relieves leg pain (sciatica) effectively for most patients, with a small incision and usually a quick recovery.

What is a microdiscectomy?

Using a microscope or magnification through a small incision, the surgeon removes only the disc fragment that is compressing the nerve, leaving most of the disc and spine undisturbed.

Who is it for?

It is usually recommended for persistent, severe leg pain from a herniated lumbar disc that has not settled with conservative treatment, or when there is nerve weakness.

The procedure and recovery

The operation is typically done under anaesthesia through a small incision. Many patients walk the same day and go home within 1–2 days, returning to light activity over a few weeks as guided.

Results and risks

Microdiscectomy relieves sciatica effectively for most patients. As with any surgery there are small risks such as infection, nerve irritation or disc recurrence, which your surgeon will discuss.

Frequently Asked Questions

How successful is lumbar microdiscectomy?

It relieves leg pain effectively for the majority of well-selected patients, though outcomes vary and cannot be guaranteed.

How long is recovery after microdiscectomy?

Many patients resume light activity within 1–3 weeks and heavier activity over 4–6 weeks, guided by the surgeon and physiotherapist.

Can the disc herniate again after surgery?

Recurrence is possible but uncommon. Good posture, core strength and safe lifting reduce the risk.
