What it is
A microdiscectomy removes the herniated fragment of a lumbar disc that is pressing on a nerve root — the usual cause of sciatica. It is deliberately limited surgery: the goal is not to rebuild the disc but to remove the piece compressing the nerve, through an incision often under an inch, using a microscope or tubular retractor.
When it's recommended
- Sciatica from a herniated disc that persists despite 6–12 weeks of genuine conservative care
- Progressive leg weakness or foot drop — where earlier surgery is often advised
- Severe, function-limiting leg pain in selected cases
As with every procedure in this practice, surgery is offered only after conservative options have been genuinely explored — or when the diagnosis clearly calls for it.
How it's performed
Under magnification, a small window is made at the affected level, the nerve is gently protected, and the herniated fragment is removed. The operation typically takes under an hour and is performed minimally invasively.
Recovery & return to activity
- Almost always outpatient — home the same day
- Leg pain relief is often rapid, sometimes immediate
- Light activity within days; desk work commonly within 1–2 weeks
- Temporary lifting and bending restrictions protect the healing disc
Recovery details vary by patient and by the specifics of each operation — your individual plan, restrictions, and milestones are set with you before surgery and refined at follow-up.
