This is a birth defect. Once in a while you have a run of cases that are interesting. In Jeddah everyone is wary of surgery. The reasons are myriad but mostly people are just plain afraid. I had some recent successes so for a few days I’ll post up some medical things.
This child was born with a failure of the spine to close over into a proper canal. So the lump is a combination of nerves and skin exposed to the air. The spinal cord begins as a plate which rolls into a tube which is surrounded by the muscle bone and skin. Failure of the tube to roll up results in this defect. It is largely unseen in the US for many years. Prenatal vitamins has pretty much made this so rare that I have not cared for such a patient in many years.
You can see that the nerve sac is incomplete and sticking out through the spine at its lower end.
Fortunately the defect may be low enough that the child will walk. His bowel bladder function may be incomplete. The repair is shown.
The wound is several days after surgery so there is a lot of swelling and bruising but the defect is covered and repaired now. Many more problems will face this child as he grows. This is the first step. The biggest challenge now was to make a proper closure and to prevent infection.
