Lumbar puncture

Lumbar puncture (LP), also known as spinal canal puncture or cerebrospinal fluid puncture, is a procedure in which a needle is inserted into the lumbar region to collect a sample of cerebrospinal fluid (CSF). CSF is a clear fluid found in the spinal cord area  and in the brain that helps protect the brain and spinal cord. 

Spinal taps are commonly used to diagnose diseases of the brain and spinal cord, such as meningitis, encephalitis, and multiple sclerosis.

It can also be used to monitor treatment for such conditions or to remove cerebrospinal fluid from the spinal cord if too much is being produced.


The procedure is usually safe and painless, but sometimes you may experience a headache or other discomfort after the puncture. If you are suspected of having brain or spinal cord disease, your doctor may recommend a spinal tap to confirm or rule out the diagnosis and plan appropriate treatment. 

Performing a lumbar puncture usually involves the following steps: 

  1. The patient is positioned on an examination table in a seated or side-lying position  and may receive local anesthesia to make the procedure painless. 

  2. The doctor chooses a spot on the patient's back to insert the needle. The needle is usually inserted into the lumbar spine because this is where the spinal canal is located. 

  3. The doctor disinfects the skin where the needle is inserted and applies sterile drapes. 

  4. The doctor inserts the needle through the skin and muscles into the spinal canal. He may use x-rays or fluoroscopy to make sure the needle is in the right place. 

  5. Once the needle is in the spinal canal, the doctor collects a sample of the spinal fluid. If necessary, he can also inject drugs into the liquid. 

  6. After the needle is removed, the puncture site is covered with a bandage. The patient may be asked to remain supine for a period of time to avoid complications such as headache or dizziness. 

At the moment in our practice  there is no liquor diagnostics. If necessary, patients are presented to a nearby clinic for neurology  for a lumbar puncture.
