Table 2 Standard step-by-step technique for LFUD and NSSD

1) Constantly move the handpiece to prevent ultrasound burning tissue

1) Start debriding at the distal most aspect of the ulcer

2) Start debriding at the distal most aspect of the ulcer

2) Moving scalpel proximally with each motion

3) Moving the handpiece left to right and from the distal to proximal aspect of the ulcer

3) Once the distal to proximal ulcer has been debrided then debride from left side to right side

4) Once the entire ulcer surface has been debrided re-commence the same technique from the distal most aspect of the ulcer

4) Continue until as much necrotic tissue has been removed as possible

5) Any peri-wound tissue that requires removal (i.e. callus, maceration) will occur using a scalpel.

5) Continue until as much necrotic tissue has be removed as possible

6) Any peri-wound tissue that requires removal (i.e. callus, maceration) will occur using a scalpel. The wound base will not be debrided with the scalpel.
