Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Data will be collected upon enrollment including:
Background and demographic information Wound size and severity Pain level Medication use Photographs of wound
Flap Reconstruction group (Standard of Care):
Patients in this group will have any dead, damaged or infected tissue removed from the wound and a negative pressure wound dressing will be applied until the wound is clean and adequate for flap reconstruction. Following flap reconstruction, patients typically require a 36-48 hour intensive care unit admission for flap monitoring and 5 days to bed rest to allow for proper healing. If the flap is successful, a dangle protocol will occur until patient increases the dependent position. Once the dangle protocol is completed, patients may require inpatient physical/occupational therapy prior to discharge from the hospital. If patient is not healing the physician may discuss other treatment options including crossing over to the EpiFix arm or amputation.
EpiFix and Skin Graft group:
Patients in this group will have any dead, damaged or infected tissue removed from wound. Once it is free from infection, a thin tissue (EpiFix) will be applied directly to the open wound. This will be covered by sterile wound dressing. After approximately 5-7 days the wound will be assessed for suitability of split thickness skin grafting. If adequately healed, skin grafting will be performed. After 5 days, the graft will be evaluated and if successful, the patient will be discharged home or to a rehab facility. If the wounds are not adequate for skin grafting, additional damaged tissue will removed and EpiFix will be placed until the wound is suitable for grafting. If you do not heal sufficiently the physician will discuss other treatment options including cross over to the standard of care Free Flap or amputation.
Study staff will evaluate the wound twice a week for the first 2 weeks, then once a week until 6 weeks. At this point, the patient will be followed every 4 weeks up to 22 weeks. Visits to the clinic will include wound measurements, photos, pain scale and evaluation of any infection.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Human Amnion/Chorion Membrane + skin graft
Dehydrated Human Amnion/Chorion Membrane (dHACM) will be placed on wound at the initial debridement to promote granulation tissue at the wound bed. Approximately 5-7 days following debridement, wound will be assessed for suitability of split thickness skin grafting. If an adequate granulation tissue is present, skin grafting will be performed and assessed for take in 5 days.
Dehydrated Human Amnion/Chorion Membrane
Flap Reconstruction (Standard of Care)
A negative pressure wound dressing (NPWD) will be applied at the time of debridement until the wound is clean and adequate for flap reconstruction. Flap-based reconstruction is performed. Following flap reconstruction,patient will have 5 days of bed rest to allow proper healing and coverage of the wounds. If flaps are successful, patients starts a limb dangle protocol which gradually increases the dependent position and allows the flap to acclimate to new physiologic demands. Following dangle protocol patient will require inpatient physical and occupational therapy prior to discharge.
