Plastic Surgery Commercially Available Plastic & Orthopedic Surgery –Soft tissue repair indications Acute trauma Post surgery closure Difficult to heal wounds No donor site surgery required 91 y/o patient with Melanoma on top of right hand. One week post surgery, full thickness remodeling initiated. Patient exhibits minimal inflammation and pain. Two months post surgery, full thickness remodeling near completion. Patient has complete range of motion.
What is an Extracellular Matrix (ECM) ECM occupies the space between cells –Is part every organ of every species –Xenogenic transferability Universal among species Complex infrastructure –Collagen types –Proteoglycans –Hyaluronic acid, laminin, fibronectin –Glycoproteins Mediates cell-to-cell interactions –Proliferation and differentiation –Modulates biological activities of growth factors

What is ACell Vet ? Extracellular Matrix (ECM) Scaffold to Promote Site Specific Host Cells to Infiltrate Naturally derived (porcine) ACell-ular No Immune System Rejection Totally Resorbable Completely Replaced By Healthy Host Tissue Not Chemically Crosslinked No Additional Chemicals to Promote Rejection
How ECMs Work Site Specific Constructive Remodeling of Host Tissue by recruitment of Peripheral and Bone Marrow Derived Progenitor Cells.

Dudley – Degloving Injury Classic degloving injury after HBC Single layer ACell Vet applied 10/11/02
Day 3 - initial formation of granulation bed apparent. ACell Vet reapplied. Dudley – Degloving Injury Day 11 - excellent granulation bed and vascularization.
Dudley – Degloving Injury Day 17 – progressing nicely Day 30 – almost closed
Dudley – Degloving Injury Day 66 – Wound barely visible and regrowth of hair proceeding nicely.
Classy Wound was unresponsive to treatment for 2 years Skin defect 12 x 14 cm. Bone defect 10 x 7 cm. Treated with ACell and surgery 8 months later Little scar
