  Purpose

The aim of this prospective study is to assess the utility of treatment of leg ulcers using a skin substitute, Integra®, assessing the quality of wound skin healing and transcutaneous oxygen pressure in the distal region of the wound.

This is a multi-centre study on 60 patients who have a lower limb ulcer.

Primary Outcome Measures:
  • Proportion of patients with a greater than 50% reduction in wound surface area during the 18 months after grafting. [ Time Frame: 18 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Functional complications of healing at 3, 6, 12 and 18 months [ Time Frame: 3, 6, 12 and 18 months ] [ Designated as safety issue: Yes ]
  • Complete wound healing (reduction in wound surface area >90%) [ Time Frame: 3, 6, 12, 18 months ] [ Designated as safety issue: No ]
  • Pain [ Time Frame: 3, 6, 12, 18 months ] [ Designated as safety issue: No ]
  • Quality of life [ Time Frame: 3, 6, 12, 18 months ] [ Designated as safety issue: No ]
  • Transcutnaeous oxygen pressure (TcPO2) [ Time Frame: 6, 12 and 18 months ] [ Designated as safety issue: No ]

  Eligibility

Ages Eligible for Study:   18 Years to 90 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population

The study population will be patients with "difficult" lower limb ulcers, whose wounds have not responded to directed healing for more than 6 months or who have a wound > 10 cm².

Criteria

Inclusion Criteria:

  • patient with a lower limb ulcer, regardless of origin (arterial, venous or mixed, diabetic foot ulcer) present for more than 6 months or large in size (> 10 cm²)
  • patients in whom the surgeon has recommended that an Integra® matrix be implanted (even if the patient is not taking part in the study) before the dermo-epidermal graft to obtain a richly vascularised neodermis.
  • not eligible for skin flap surgery,
  • the patient or patient's representative has agreed to sign the information letter before any investigation required by the research.

Exclusion Criteria:

  • circumferential wound,
  • wound infection
  • immunosuppressed patient,
  • known allergy to bovine collagen, bovine glycosaminoglycans or silicone,
  • patients under legal guardianship,
  • pregnant women
  • patients whose health would compromise follow-up for at least 18 months,
  • patients whose mental health would compromise completion of the self-evaluation questionnaires.
  • wound located in an area not visible by the patient (as no self-assessment would be possible).
