An evaluation of an ultrasonic debridement system in patients with diabetic foot ulcers: a case series.

OBJECTIVE: This study evaluated the use of ultrasonic debridement in patients with diabetic foot ulcers (DFU).

METHOD: In this prospective, single-arm, open-label study, all patients with DFUs underwent wound debridement by ultrasonic debridement system (SonicOne OR Ultrasonic debridement system). Wherever possible, the edges were approximated by means of stitches. In other cases, the surgical breach healed by secondary intention, or a partial thickness skin graft (with or without Integra Dermal Regeneration Template or Integra Flowable Wound Matrix) was applied, and subsequently healed by primary intention.

RESULTS: We assessed 15 patients with a DFU. The time required for debridement was short (an average 15.06±4.02 minutes). Complete wound healing (defined as 100% re-epithelialisation) was achieved in all 15 cases. Median time to heal was 39.20±16.05 days. The ultrasonic debridement system was found to show adequate debridement while preserving more viable tissue to promote rapid healing.

CONCLUSION: Our findings show that the device demonstrates advantages in the reduction of debridement times, and efficacy in safely preserving the viable tissue, with a low complication rate in surgery of DFUs. A study that uses a larger cohort is required to fully evaluate the effectiveness, or otherwise, of the ultrasonic debridement system.
