The full tear through the annular wall does not heal. However, there is some vascularity of the outer 1/3 of the disc and that section can form a scar or “membrane” that can resist further herniation. This membrane is only a fraction of the strength of the original annulus which explains the 10% reherniation rate.
It is estimated that this membrane takes about 6-8 weeks to form and I can tell you that it does not always form in every patient. This is why I have patients be careful about lifting for 6-8 weeks while retraining them in physical therapy.
I think by eight weeks this membrane will be a formed as it is going to be.
