Spine Surgery: Microdiscectomy

A microdiscectomy, also known as microdecompression or microdiscectomy spine surgery, is a surgical procedure performed to relieve pressure on the spinal nerves caused by a herniated disc. This procedure is commonly used to treat conditions such as sciatica, which is pain that radiates along the path of the sciatic nerve, often caused by a herniated disc in the lower back.

Here is an overview of the microdiscectomy surgical procedure:


  • Microdiscectomy is typically recommended when a herniated disc in the spine is pressing on a nerve root, causing pain, numbness, or weakness. The procedure aims to remove the portion of the disc that is impinging on the nerve.

Minimally Invasive Approach

  • Microdiscectomy is considered a minimally invasive surgery, which means it involves smaller incisions than traditional open surgeries. This approach helps minimize damage to surrounding tissues and allows for a quicker recovery.


  • The procedure is usually performed under general anesthesia, which means the patient is asleep and does not feel pain during the surgery.


  • The surgeon carefully moves aside muscles and tissues to access the spine. Using specialized instruments, the surgeon then removes the part of the herniated disc that is pressing on the nerve root. This process is known as a discectomy.

Nerve Decompression

  • By removing the portion of the herniated disc, pressure on the nerve root is relieved, and the nerve can function more normally. This can alleviate pain, numbness, and other symptoms associated with nerve compression.


  • Patients typically experience a relatively quick recovery after a microdiscectomy. The minimally invasive nature of the procedure often allows for a shorter hospital stay and a faster return to normal activities compared to traditional open surgeries.

It’s important to note that while microdiscectomy is generally a safe and effective procedure, as with any surgery, there are potential risks and complications. Patients should discuss the procedure, potential risks, and expected outcomes with their healthcare provider before making a decision.
