Default Growing rod extensions

Hi Dr S,

Was just wondering with lengthenings in 3 weeks, why is the infection rate so high with growing rods? We have been told it is 20% infection rate by our Surgeon, but didnt think to ask why? Is it because of the moving parts in the rods or because of repeat surgeries? Or is there another reason?

Thanks
Tracy

Thank you for your enquiry.

The simple explanation for why there is a high infection rate with so-called "growing" rods is because they are usually quite superficial in the spine and because there is micro-movement in the rods this results in tissue irritation with what is called serum or tissue fluid around the parts that are moving. This becomes a favourable location for bacteria to lodge. Further, whenever surgeries have to be repeated this increases the risk of infection irrespective of the nature of the surgery. Surgery always leaves behind some scar tissue, irrespective of the site of the surgery or its nature. Scar tissue usually does not have a good blood supply and so has a decreased resistance to infection. By contrast, cuts on the face which bleed profusely hardly ever get infected because of the splendid blood supply.

You should certainly discuss the matter on your next follow-up visit.

I trust these remarks are helpful.

Dr S,

Thankyou for your reply. Would antibiotics before Surgery help? Will make more enquiries at pre-op appointment.

Thankyou

Tracy

Thank you for your further question concerning growing rods. For most scoliosis surgery antibiotics are routinely used, the first dose being given at the commencement of anaesthesia. You should discuss this with the surgeon before the operation.
