Son born with severe cerebral palsy. At 12 went into puberty and by 13 had an 82 degree curvature. Had surgery...2 rods posterior with one cross bar, 6 screws, three each side in the lumbar region and wires. Between then and 15 he grew more, developed crankshaft where there was worsening of the curve and rotation of the vertebrae and ribcage. The cross bar pushed on the skin from the inside and eventually caused an infection. At 15 he had surgery. They removed the rod and cleaned things out, did the vacuum thing and went back in two days later and cleaned and closed up.
The bacteria's identified were coagulase negative staph & Propionibacterium acnes. After two years on antibiotics in an attempt to keep the bacteria on the hardware they broke loose and he has another sinus tract about halfway between the last one and the behind. It's on it's 4th round of getting ready to release some puss. The infection is between L2 and L3. That's the general area of some of the screws. Because he has been diagnosed with severe restrictive lung disease he is no longer a candidate for surgery, plus the ortho surgeon said she hadn't realized how much he had rotated. The left rod is more like on the left side and very embedded. It was agreed between her, the pulmonologist and ourselves that surgery and total removal of the hardware was not an option. If anything it would probably kill him. Not long after that he developed regular bladder infections and even more issues with retention/cathing etc. He is now at home on in home hospice. I tell myself that the odds that the infection after a year of the bacteria running loose, slow growing or not, not being in the bones...especially where the screws go into the vertebrae..are slim. Wondering if anyone has had experience with having had spinal surgery and developing a later onset infection and did it invade the vertebrae or the disc area.
