  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Male or female age 18 or older
  2. Informed consent must be obtained
  3. Patient's ulcer must be diabetic in origin and larger than 1cm2. Debridement will be done prior to randomization. Subject's informed consent for participating in this study, must be obtained prior to proceeding with sharp debridement.
  4. Patients with Type 1 or Type 2 diabetes (criteria for the diagnosis of diabetes mellitus per ADA).
  5. Ulcer must be present for a minimum of four weeks before enrollment/randomization, with documented failure of prior treatment to heal the wound. A two week run in period will precede enrollment/randomization in the trial to document the indolent nature of the wounds selected
  6. Additional wounds may be present but not within 3cm of the study wound
  7. Wound must be present anatomically on the plantar surface of the foot
  8. Patient's ulcer must exhibit no clinical signs of infection.
  9. Patient is of legal consenting age.
  10. Patient is willing to provide informed consent and is willing to participate in all procedures and follow up evaluations necessary to complete the study.
  11. Serum Creatine less then 3.0mg/dl
  12. HbA1c less than 12%
  13. Patient has adequate circulation to the affected extremity, as demonstrated by one of the following within the past 60 days:

    • Dorsum transcutaneous oxygen test (TcPO2) with results ≥30mmHg, OR
    • ABIs with results of ≥0.7 and ≤1.2, OR
    • Doppler arterial waveforms, which are triphasic or biphasic at the ankle of affected leg

Exclusion Criteria:

  1. Patients presenting with an ulcer probing to bone (UT Grade IIIA-D). A positive probe-to-bone will be confirmed when bone or joint can be felt with a sterile, ophthalmological probe.
  2. Patients whose index diabetic foot ulcers are greater than 25cm2.
  3. Patients considered not in reasonable metabolic control, confirmed by an HbA1c greater than 12% within previous 90 days,
  4. Patients whose serum creatinine levels are 3.0mg/dl or greater.
  5. Patients with a known history of poor compliance with medical treatments.
  6. Patients who have been previously randomized into this study, or are presently participating in another clinical trial
  7. Patients who are currently receiving radiation therapy or chemotherapy.
  8. Patients with known or suspected local skin malignancy to the index diabetic ulcer.
  9. Patients diagnosed with autoimmune connective tissues diseases.
  10. Non-revascularizable surgical sites
  11. Active infection at site
  12. Any pathology that would limit the blood supply and compromise healing;
  13. Patients that have received a biomedical or topical growth factor for their wound within the previous 30 days
  14. Patient who are pregnant or breast feeding
  15. Patient who are taking medications that are considered immune system modulator which could affect graft incorporation.
  16. Allergy to Gentamycin or Streptomycin
  17. Wounds greater than one year in duration without intermittent healing
  18. Wound improving greater than 20% over the first two weeks of the trial using standard of care dressing and Cam Boot
