Management of Complex Wounds Using a Constant Tension External Tissue Expander
Complex wounds that cannot be closed primarily are at great risk for complications. A new technique utilizing external tissue expansion holds promise in rapidly decreasing wound area. Facilitation of rapid wound closure is critical in preventing wound complications.
Hypothesis:
Using the Dermaclose Wound Management System (Woundcare Technologies, Inc., Chanhassen, MN) in complex wounds not able to be primarily closed will decrease the time to secondary closure and decrease the need for secondary soft tissue coverage procedures, or if secondary soft tissue procedures are required, its use will decrease the size and complexity of the secondary soft tissue procedures.
Null Hypothesis:
The Dermaclose system will not decrease the need, dimensions, or complexity of secondary soft tissue coverage procedures in complex wounds not able to be primarily closed.
Studieöversikt
Detaljerad beskrivning
Upon IRB approval, 50 patients with complex soft tissue wounds, with or without an associated fracture that cannot be closed primarily will have the Dermaclose device applied and will be prospectively followed for 1 year. The Dermaclose device will be applied according to the manufacturer's guidelines. This device may be combined with the use of Negative Pressure Wound Therapy. Primary and secondary end points that were initially intended to be included are listed below. However, on SF12 and pain outcome measures were collected and reported.
Initially Intended Primary end points (only SF12 collected and reported):
SF12
- Initial and final wound dimensions
- Secondary soft tissue coverage procedures
- Dimensions and type of secondary soft tissue coverage procedures required compared to initial wound dimensions
- Method of wound closure
- Days to wound closure
- Number and types of procedures required for wound closure
- Infection requiring reoperation
- Wound dehiscence requiring reoperation
Initially intended Secondary end points (only #3 collected and reported):
- Superficial wound dehiscence not requiring reoperation
- Superficial wound infection not requiring reoperation
- Visual Analog Pain Scale (VAS) with Dermaclose use
- Use of negative pressure wound therapy
- Cost-to-benefit ratio of Dermaclose use - hospital days, number of procedures, procedural and hospital costs including device, negative pressure wound therapy costs, and operating room time and associated costs
Patients will be evaluated daily during their inpatient hospital stays for VAS related to the wound for which the Dermaclose device is used. If the Dermaclose device is used on an outpatient basis, the patient will be asked to complete a daily VAS at the same time to monitor pain associated with device use. After hospital discharge, the patients will be evaluated at 2 weeks, 6 weeks, 3 months, 6 months, and 12 months. They will complete an SF-12 as part of the above evaluations. Patients may be evaluated at more frequent intervals if the need arises. Primary and secondary endpoints will be evaluated at each time point.

Experimentell: DermaClose Group
DermaClose device applied to complex soft-tissue wound, with or without negative pressure wound therapy, and prospectively followed for primary and secondary outcomes for one year.
|
The DermaClose external tissue expander provides continuous expanding of the skin around a wound until it has stretched enough to suture the wound edges closed.

Quality of Life
Tidsram: 6 months
|
The SF-12 contains 12 items from the SF-36 Health Survey - . The SF-12 contains one or two items that measure each of the eight concepts included in the SF-36. The Quality of Life SF-12 is a scale from 0 - 100, in which 0 = poor functioning and 100 = excellent functioning. |

Pain
Tidsram: 6 months
|
Visual Analog Pain Scale (VAS) with DermaClose use, and on study wound at 2 weeks, 6 weeks, 3 months, 6 months, and 12 months.
The scale goes from 0 to 10 with 0 being no pain and 10 being the most severe pain imaginable.
It is a visual analog scale so is continuous data.
