Fig. 5From: Minimal invasive annulotomy for induction of disc degeneration and implantation of poly (lactic-co-glycolic acid) (PLGA) plugs for annular repair in a rabbit modelRepresentative magnetic resonance image (MRI) of the discs before surgery (a) and after surgery (b). Significant low T2-weighted signal intensity was clearly visible at the three experimental levels after surgery. The white asterisk indicates the partial loss of T2 signal intensity. The arrows indicate the operated discBack to article page
