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

Study Overview
=================
Brief Summary
-----------------
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.

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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Wound closure evaluation | 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 | One week after transplantation of the autologous epidermis, the survival rate of skin grafting on the exposed tendon wound is localized. | 7 days after the patient implanted the autologous blade thick skin tablet | 
| Functional evaluation | Quick DASH | 3 months after surgery | 
| Functional evaluation | Quick DASH | 6 months after surgery | 
| Functional evaluation | Range of motion | 3 months after surgery | 
| Functional evaluation | Range of motion | 6 months after surgery | 
| Appearance evaluation | VSS（Vancouver scar scale） score of the receiving area .About scars, color 0 3 points; Thickness 0 4 minutes; Vascular distribution 0 3 points; Softness: 0 5 points. All the points are added together, the smaller the better. | 3 months after surgery |
