Can you please explain what T2-L1 Posterior Scoliosis Correction means?

I don't know how to understand T2-L1 thanks in advance.

Thank you for your enquiry. First and foremost, be assured that scoliosis surgery these days is very safe and presumably the operation will be carried out with what is called spinal cord monitoring at the same time.

If you are not at ease with the decision to proceed with the operation you should ask the surgeon to arrange for a second opinion. Every patient has this right irrespective of the nature of the problem and doctors welcome this because it puts the relationship on a firm footing. Do not hesitate to approach the surgeon in this regard. A simple call to his secretary could set the process in place and I note that the surgery is not scheduled until 18 October.

Patients with scoliosis of the adolescent idiopathic type, which I presume is the type of curve your son has, tend to be quite tall and thin for reasons which are not clear. If he does a little bit of exercise, which accrues nothing but benefit, that will tend to make him more hungry. The fact that he is slender makes the operation a little easier.

In your post of 19 September 2011 you posed a question. First, a T2-L1 posterior scoliosis correction/allograft means that the extent of the spinal fusion will go from the second thoracic vertebra to the first lumbar vertebra. The surgeon intends to use allograft which is human bone which has been collected for the purpose and which is rigorously tested to ensure it is suitable for the purpose. If the patient donates his own bone, usually from the pelvic area, this is called an autograft.

The T2-L1 posterior scoliosis correction is a name for the operation of spinal fusion where rods are used to correct the curvature and hold it in the corrected position while the bone graft heals. We have 12 thoracic vertebrae and 5 lumbar vertebrae.

Be sure to write down your questions before you see the surgeon again prior to the operation as this simple precaution will ensure that all your questions are answered.

I trust this information is helpful.

Thank you very much Dr Scoliosis. Do you think he will be able to bend much after this operation. Is that a very long rod?

What does posterior mean? I thought the doctor said he would be operating from the back and another mother just advised that the back is called anterior?

Thank you for your further enquiry.

A fusion from T2-L1 will result in surprisingly little stiffness in everyday activities. Very little bending takes part in the thoracic spine but rotation does occur here. There will be no movement in the area of the spine encompassed by the fusion, that is, from T2-L1. However, when we bend forward to tie up our shoelaces, most of that movement occurs in the hips, not the spine. However, in your sonís case he will also have five movable discs in the lumbar region.

The operation as described by you would make very little difference to movement in normal day-to-day activities. Because of the stiff segment it is usual to advise against participation in contact/collision/high impact sports because of the reduction in flexibility.

I trust this information is helpful. You should discuss the matter in detail with the surgeon prior to the operation.

In response to your last post there is some confusion in the terminology. Most scoliosis corrections done from the back, that is the posterior aspect of the trunk, are mid line and vary in the extent of the incision.

When an anterior procedure is carried out, the incision is on the side of the trunk either in the thorax or on the abdominal wall. The mother who "just advised that the back is called anterior" has misinterpreted the information she had been given.

The indications for anterior and posterior procedures differ considerably and in individual cases this should be discussed with the surgeon.

I trust the matter is now clarified.
