Would it be possible to fully heal spondylolysis?

Spondylolysis: Apologize for reading spondylosis instead of spondylolysis. I agree with dr. Estrada bernard's comment. I have patients with this condition that manage with pain injections and physical therapy. If all else fails a fusion procedure may be indicated.

Sometimes: Depends on whether the defect/fracture is acute or chronic. In acute fracture your body may heal across the fracture, but in chronic cases or congenital cases this likely will never happen. However if you are symptomatic from the defect and studies corroborate this and you have failed conservative rx, then a pars repair may heal this operatively if you are a candidate for that operation.

Depends: Spondylolysis refers to a defect in a part of the spine structure called the pars. It is also called a pars defect. Some cases are congenital , others are from trauma and others may be uncertain. Most do not need surgery. The ones that do are associated with significant pain, nerve dysfunction or signs of spine instability
