Evaluation of a New Device "Orthèse Diabète" in the Healing of Foot Ulcers in Diabetic Patients

Not Applicable
Completed
Conditions
Foot Ulcer, Diabetic
Interventions
Device: Orthèse Diabète
Device: "Conventional" Device
Registration Number
NCT01956162
Lead Sponsor
Proteor Group
Brief Summary

Multi-center trial, randomized in 2 parallel groups, open label, with a blinded adjudication committee (PROBE methodology), comparing "Orthèse Diabète" with "conventional" removable devices in terms of healing of ulcers.

- Primary objective: Evaluate the efficiency of "Orthèse Diabète" compared to "conventional" removable devices, in terms of the proportion of diabetic patients whose principal ulcer will heal completely at 3 months.

Detailed Description

1. Secondary objectives

1. Proportion of patients whose principal ulcer will heal completely at 1, 2 and 6 months

2. Proportion of patients in whom all initial plantar ulcers will heal completely at 1, 2, 3 and 6 months

3. Percentage of area decrease of the plantar ulcers at 1, 2, 3 and 6 months

4. Time to healing of the principal ulcer

5. Appearance of new ulcers

6. Requirement for amputation

7. Incidence of the infectious complications

8. Adherence of wearing

9. Patient's satisfaction with the prescribed device

2. Population

1. 13 centers/116 patients monitored for a period of 6 months maximum

2. Experimental Group: "Orthèse Diabète" a plantar off-loading custom-made removable device

3. Control group: "Conventional" removable off-loading systems among the devices available in France.

Primary Outcome Measures
NameTimeMethod
Evaluate the efficiency of "Orthèse Diabète" compared to "conventional" removable devices, in terms of the proportion of diabetic patients whose principal ulcer will heal completely.At 3 months

Evaluated by taking photographs, measuring the ulcer area (using Digital Photo Planimetry DPP and the software Tracer.exe). Full healing defined by the adjudication committee based on the analysis of the photographs.

Secondary Outcome Measures
NameTimeMethod
Proportion of patients whose principal plantar ulcer will be fully healedAt 1, 2 and 6 months

Evaluated by taking photographs, measuring the ulcer area (using Digital Photo Planimetry DPP and the software Tracer.exe). Full healing defined by the adjudication committee based on the analysis of the photographs.

Proportion of patients whose all initial plantar ulcers will be fully healed.At 1, 2, 3 and 6 months

Evaluated by taking photographs, measuring the ulcer area (using Digital Photo Planimetry DPP and the software Tracer.exe). Full healing defined by the adjudication committee based on the analysis of the photographs.

Percentage decrease of the ulcer areaAt 1, 2, 3 and 6 months

The area is evaluated by the last measurement undertaken during the trial or prior to a serious event (death, amputation, orthopedic or vascular surgery).

Time to healing of the principal ulcerFrom the patient's off-loading device delivery visit to the date of healing validated by the adjudication committee
Appearance of new ulcers on the affected foot and/or contralateral6 months

The following elements will be specified: cause, side, location, severity, treatment used

Requirement for amputation6 months

The following elements will be specified: date, side and level.

Incidence of infectious complications6 months

This covers cutaneous infections (abscess and lymphangitis, erysipelas, hypodermitis, necrotizing fasciitis, gas gangrene), bone infections (osteitis, arthritis, osteoarthritis) or systemic infections requiring antibiotic therapy (oral or parenteral) or surgery.

Observance of the equipment6 months

Daily wear will be evaluated in the 2 groups through a semi-quantitative questionnaire provided to the patient at every visit. This evaluation will be supplemented with readings of the thermal sensor in the "Orthèse Diabète " group

Patients satisfaction with the prescribed deviceAt 3 months

Evaluated with the "QUEST ESAT" questionnaire
