Hi, very interesting findings in this forum. My son just turn 12 and started feeling back pain in his right side lower back only when swinging from the left side(he's a switch-hitter.) It was basically while batting practice after 10-11 swings. No pain while throwing or doing other things. I took him directly to a spine orthopedist Dr. He ordered a CT scan and a bone scan. I was almost sure he had spondylolysis. To my surprise both test came negative. So, Dr. ordered an MRI. MRI report says: L5-S1: marrow edema in the rigth pedicle and pars consistent with a stress fracture. CT correlation helpful.
My question is: is this only a stress reaction? Why does the marrow edema doesn't show on the CT and bone scan? Dr. says there's no fracture but he ordered a brace for 6 wks. I just want to make sure there is really no fracture. Thanks! This forum is awesome and good luck to all.
