Lumbar Discectomy (Open / Microdiscectomy)

Open or microscopic removal of a prolapsed lumbar disc compressing the sciatic nerve. Used when the anatomy or extent of prolapse makes open surgery the safest option.

Lumbar Discectomy (Open / Microdiscectomy) — treatment

What the procedure is

Open lumbar discectomy removes the prolapsed fragment of disc pressing on the sciatic or lumbar nerve root. Using a standard posterior approach or a microscope-assisted technique, Mr. Rath removes the herniated material through an incision in the lower back. This approach is selected when the prolapse is large, calcified, or positioned in a way that makes endoscopic access less optimal — for example, after previous spinal surgery where scar tissue around the nerve root makes endoscopic visualisation less reliable.

On the day

You'll arrive in the morning for pre-operative preparation. The procedure takes approximately one to two hours under general anaesthetic. Mr. Rath uses a microscope or loupes for magnification to identify and protect the nerve root while removing only the prolapsed disc material.

Mobilisation begins within 1–2 hours of surgery, with walking encouraged on the evening of the procedure.

Why Mr. Rath's approach

Not every prolapsed disc is best treated endoscopically. Mr. Rath offers both approaches and selects the one most likely to provide complete decompression and the lowest complication risk based on your MRI and anatomy. His primary commitment is to outcome, not technique for its own sake.

Risks and considerations

  • Recurrent disc herniation (around 1 in 10 over 5 years)
  • Dural tear (uncommon, usually managed intra-operatively)
  • Persistent leg pain (nerve recovery can take weeks to months)
  • Infection (rare)

Mr. Rath will discuss your specific anatomy and risk profile at consultation.

Recovery timeline

  1. Day of surgery · Overnight stay

    Most patients stay one night. Mobilisation begins within 1–2 hours of surgery. Walking is encouraged on the evening of the procedure.

  2. Week 1-2 · 2 weeks

    Home recovery with regular short walks. Avoid heavy lifting and prolonged sitting.

  3. Week 3-4 · 2 weeks

    Return to desk work. Physiotherapy begins around week 4 to rebuild strength. Driving resumes at 2–3 weeks. Leg pain typically resolves faster than back pain.

  4. Week 6 · 6 weeks

    Phase-wise return to normal activity guided by Mr. Rath at the 6-week review, including light exercise.

Frequently asked
What is the difference between open discectomy and endoscopic discectomy?

Open discectomy uses a larger incision and requires retracting the back muscles. Endoscopic discectomy uses a narrow tube and camera through a sub-centimetre incision, causing less tissue damage and allowing same-day discharge. Mr. Rath will recommend the best approach for your anatomy.

Will the disc prolapse again after surgery?

Recurrent disc prolapse occurs in around 1 in 10 cases over 5 years regardless of approach. Mr. Rath will advise on activity modification to reduce this risk.
