Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A randomized controlled trial is performed to evaluate the effectiveness and safety of the Skin Stretching Device (SSD) on limb tension incision closure by comparing whether the differences in wounds area, wounds closure time and scar assessment between the SSD and the skin grafting are statistically significant.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Design:

This study is a multicenter and randomized control study with the participation of 15 major national or regional central hospitals. And the whole sample size is set to be 100 patients.

Patients who have been screened by inclusion and exclusion criteria will be randomly (non-transparent envelope) assigned to Skin Stretching Group (SS Group) or Skin Grafting Group (SG Group). Patients of both group will undergo surgical debridement for the same principle, while the Skin Stretching Device is used for the patients of SS Group for incision closure and the Skin Grafting is used for the patients of SG group for incision closure.

Outcome evaluation:

Wound and scar evaluation during surgery, three and six months after surgery will include the following parameters:

* surface area;
* Vancouver scar scale (VSS)
* vascularization and pigmentation;
* dermal architecture. After 3 and 6 months patients will undergo a biopsy of the scar under local anesthesia. The experimental group, treated with the SSD will undergo one extra biopsy of the formerly stretched skin.

Safety evaluation:

During the trial, adverse events are observed and evaluated. Adverse reactions to clinical manifestations are followed and recorded till the symptoms disappear. The subject with serious adverse events shall withdraw from the study and be treated accordingly.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Skin Stretching Device (SSD)

the wound is primarily closed by aid of the SSD after necessary surgical debridement.

Group Type EXPERIMENTAL

Skin stretching device (SSD)

Intervention Type DEVICE

By making use of skin viscoelasticity, the special metal crochet of SSD would be embedded in both sides skin of the wound. Multiple cycles of stretching and relaxing wound lead to extended skin, changing the high tension incision into a low tension incision and facilitating the direct suture.

Skin Grafting (SG)

the wound is primarily closed by the technique of skin grafting after necessary surgical debridement.

Group Type ACTIVE_COMPARATOR

Skin grafting

Intervention Type PROCEDURE

the standard technique of skin grafting after wound preparation.
