What To Expect

After surgery, you will be encouraged to get out of bed and walk as soon as the numbness wears off. You can use prescription medicines to control pain while you recover. You can slowly resume exercise and other activities.

Other things to think about include the following:

• You may not be comfortable sitting at first. Most people avoid having to sit for longer than 15 or 20 minutes. But sitting will feel more comfortable over time.
• Walk as often as you can for the first several weeks. Getting up often to walk around will help lower the risk that too much scar tissue will form.
• Many people are able to resume work and daily activities soon after surgery. In some cases, your doctor may suggest a rehabilitation program. This may include physical therapy and home exercises.
• If you work in an office, you may go back to work in 2 to 4 weeks. If your job requires physical labor (such as lifting or operating machinery that vibrates) you may be able to go back to work 4 to 8 weeks after surgery.

How Well It Works

Although surgery for a lumbar herniated disc doesn’t work for everyone, it works well for many people.

A study called SPORT randomly assigned about 500 people to two groups. Some had surgery, and some did not. The study found that after 2 years most people felt better and were able to be active, whether they had surgery or not. People who had surgery were slightly more likely to feel better. But the difference wasn’t big enough to prove that one treatment is better than the other.^{footnote 1}

Another study followed about 500 people over 10 years. Some had surgery, and some did not. This study showed that people who had sciatica from a herniated disc tended to feel better sooner if they had surgery. But after 5 to 10 years, the number of people in both groups who were able to do their daily activities was about the same whether they had surgery or not.^{footnote 2}

What To Think About

Discectomy for a lumbar herniated disc may provide faster pain relief than nonsurgical treatment. But it is unclear whether surgery makes a difference in what treatment may be needed later on.

People who have had either standard discectomy or microdiscectomy have reported similar improvements one year after surgery.^{footnote 3}

Spinal fusion is a procedure that joins together bones in the back. For the low back (lumbar spine), spinal fusion is controversial and complex and is not commonly done with a discectomy. If a doctor suggests that you get a lumbar spinal fusion with a discectomy, get a second medical opinion to help you decide whether fusion is needed.

A newer form of discectomy using laser beams (laser discectomy) is still in the research stage.
