Figure 7

Before (left panel) and after (right panel) photographs of scar during full flexion of right erectus spinae muscle showing softening and remodeling of scar and overlying skin at 12 weeks post procedure (right panel) in addition to less movement and adherence of scar with muscle flexion. Note that both erectus spinae muscles of the back were fully functional as local lidocaine was fully dissipated and metabolized at 12 weeks and ultrasound was still able to confirm the underlying voluntary movement and flexion of muscles (not pictured).
