Hi Krystian
Pars Defect is mostly related with patients with spondylolisthesis because the defect in the pars allows the vertebrae to shift forward to the adjacent vertebrae . There are varying degrees of spondy (levels 1-4) depending on the shift of the vertabrae. I would suggest you search the web for pars defect and spondylolisthesis. In addition, I suggest you discuss playing further sports with your doctor.
In my case, I had a level 2 spondylolisthesis due to a pars defect after being hit in the back playing soccer. It did inhibit my ability to continue playing further sports but each person is different.
You are too young to begin having back problems and I pray your doctor has good news for you and can find a treatment to help your back pain.
Take Care :tup:
