What is this treatment?
Microdiscectomy is a minimally invasive surgical procedure used to remove the portion of a prolapsed disc that is pressing on a spinal nerve. It is most commonly performed to relieve leg pain (sciatica) caused by nerve compression.
There can be improvement or relief of back pain in 40% patients, but it is not guaranteed.
At One Orthopaedics, injections are performed with precision under imaging guidance to ensure accurate placement and maximise effectiveness.
Conditions treated
When is it recommended?
Microdiscectomy may be advised when:
- Persistent leg pain continues despite conservative treatment
- Weakness, numbness or altered sensation develops
- Imaging confirms nerve compression
- Symptoms are significantly affecting quality of life
How the procedure works?
- A small incision is made in the lower back
- A Microscope is used for precision
- The disc fragment compressing the nerve is removed
- Generally an overnight stay in hospital but some patients have had it as a day case.
Benefits:
- Addresses the underlying cause of nerve pain
- Minimally invasive approach
- Faster recovery compared to traditional open surgery due to reduced muscle trauma
- High success rates for relieving leg pain
Recovery and rehabilitation
- Early mobilisation is encouraged following surgery.
- A structured physiotherapy programme supports recovery and gradual return to daily activities.
- Follow up is always arranged to review your response to the procedure.
Risks and Considerations
All surgical procedures carry some level of risk. These will be discussed in detail during your consultation, along with how they relate to your individual case.
Potential risks include:
- Infection
- Bleeding
- Dural tear (leak of spinal fluid)
- Nerve injury
- Recurrence of disc prolapse
- Ongoing or persistent symptoms
Less common risks may include:
- Incontinence or sexual dysfunction (approximately 1 in 3,000 cases)
- Serious complications that may be life-threatening (approximately 1 in 100,000 cases)
- Extremely rare complications such as loss of vision (estimated at around 1 in 1,000,000 cases)
Your surgeon will take every precaution to minimise these risks and ensure your safety throughout the procedure and recovery.
Frequently asked questions
How long is recovery?
Recovery varies from person to person, but most patients are able to return to light activities within a few weeks.
- Gentle mobilisation is encouraged soon after the procedure, with many patients discharged the following day.
- You will be guided through physiotherapist-directed exercises to support your recovery.
- It is important to avoid sports and strenuous activity until after your follow-up consultation and clearance from your surgeon.
Your recovery plan will be tailored to you, ensuring a safe and gradual return to normal activities.
