A tethered cord is a complex condition that occurs before we are born (in the womb). A tethered cord means that the bottom end of the cord is fixed therefore stopping the spinal cord from moving freely. This can lead to neurological problems that affect the function of the legs, bladder, and bowels, as well as back pain and poor back mobility.

A tethered cord will commonly occur with spina bifida, meaning that one or more of the bones in the back is not formed properly. As a consequence, there is then a gap in the lower back and therefore risk of damage to the spinal cord.

In the first four weeks of fetal development, the beginnings of the brain and spinal cord are developed. If this does not develop correctly when it can lead to a tethered cord. It is important to note that not all children will need to have surgery, this will depend on the severity and symptoms that it is causing.

Here are some of the signs and symptoms that doctors look for when diagnosing a tethered cord:

  • Lump, tuft of hair or dimple on the bottom of the spine – this is known as a skin marker
  • Abnormalities in the lower limbs – weakness and deformities
  • Curvature of the spine – scoliosis
  • Urinary incontinence, bed wetting or problems with potty training – urinary problems

 

If these are found then you will be referred to have a neurological examination and an MRI scan to visualise any abnormalities.

 

As mentioned before, surgery is not always required. If it is needed, the aim is to stop the child’s symptoms from worsening. In some cases, the functions will be restored after the surgery, however this is not always the case. During the surgery the spinal cord tether is released to take away the pressure.

 

Before your child goes ahead with any surgery, your doctor will go over the risks, recovery process and answer any questions before hand.
