Double-layer Artificial Dermal Repair Material Combined With Growth Factors is Used for Exposed Tendon Wounds

October 26, 2022 updated by: Wang xingang

A Prospective Cohort Study Evaluating the Efficacy of a Double-layer Artificial Dermal Repair Material Combined With Growth Factors for Exposed Tendon Wounds

Compared with the combination of double-layer artificial dermal repair materials combined with growth factors, and the treatment methods using double-layer artificial dermal repair materials, the time and effect of the two treatment regimens on the function and appearance of wound repair with exposed tendon were different, as well as the medical costs.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

This study used a prospective cohort study to select all patients who met the inclusion criteria in six hospitals within six months after the start of the trial, including no less than 55 patients receiving artificial dermis combined with growth factor and no less than 110 patients receiving simple artificial dermal treatment, and the cumulative number of patients was not less than 110 patients, to compare the time and effect of the two treatment options on the functional and cosmetic restoration of upper limb wound repair with exposed tendons.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Sampling Method

Non-Probability Sample

Study Population

All patients who met the inclusion criteria were selected for treatment at 6 hospitals

Description

Inclusion Criteria:

  1. Elbow joint to fingertip area, soft tissue defect accompanied by tendon exposed fresh wound, tendon exposed wound area of 2~20cm2, wound area 5-600cm2, need to transplant autologous skin;
  2. Incomplete aponeurosis;
  3. Voluntarily sign the informed consent form. For persons with no or limited capacity for civil conduct, obtain the consent of their guardians and sign an informed consent form.

Exclusion Criteria:

  1. Wound infection or suspected osteomyelitis;
  2. Chronic wounds;
  3. More than 2/3 of the exposed tendons are suspended on the wound surface;
  4. Those with serious primary diseases such as cardiovascular and cerebrovascular, liver and kidney and hematopoietic system, which cannot be treated by surgery;
  5. Those who are allergic to collagen and chondroitin sulfate;
  6. Other persons that the investigator deems unsuitable.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Wound closure evaluation
Time Frame: Two successive observations confirm the time when the wound is completely closed
After transplantation of the autologous epidermis, it takes for the exposed tendon wound to heal 100%.
Two successive observations confirm the time when the wound is completely closed
Wound closure evaluation
Time Frame: 7 days after the patient implanted the autologous blade thick skin tablet
One week after transplantation of the autologous epidermis, the survival rate of skin grafting on the exposed tendon wound is localized.

Study Major Dates

Study Start (Anticipated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
