|Wound Healing - Medical Animation
|MEDICAL ANIMATION TRANSCRIPT: |
An injury to the skin, such as a cut, scrape, or puncture wound kills nearby cells and damages underlying structures and triggers the complex process of repairing the skin. Wound healing is a three-step process. The inflammatory phase begins immediately upon injury. Blood vessels constrict to reduce blood loss. Then, platelets arrive to plug the leak. The platelet plug initiates the clotting mechanism by facilitating the reactions of plasma proteins called clotting factors, which interact to form a fibrin clot. After the clot forms, the blood vessels vasodilate and become more porous to allow white blood cells to leave the blood vessel and populate at the site of injury. During this process called phagocytosis, white blood cells eat debris and kill bacteria, reducing the risk of infection. The proliferative phase begins two days to three weeks after injury. The first step in the proliferative stage is granulation. Connective tissue cells, called fibroblasts, lay a matrix of collagen that reinforces the wound and provides structure for other cells. Collagen then contracts to pull together the margins of the wound. Angiogenesis, or the growth of new blood vessels, begins almost simultaneously and supplies oxygen to the repairing cells. Epithelialization is the restoration of the protective skin barrier. Epithelial cells migrate from the margins of the wound, protected by the scab, until they meet. Eventually, the scab falls off. The remodeling phase begins several weeks after the injury and can continue for years. During this phase, a new, more organized collagen matrix forms in the wound bed and capillaries disappear, leaving an avascular scar. One possible complication of wound healing is keloid formation. A keloid results from an overgrowth of granulation tissue extending beyond the borders of the original wound. Composed of mostly collagen, keloids are slow-growing. They do not regress spontaneously, and tend to reoccur after excision. A common initial treatment for keloids includes multiple injections of corticosteroids to help reduce the size of the scar. ♪ [music] ♪
|What attorneys say about MLA and The Doe Report:
|"Thank you for the splendid medical-legal art work you did for us in the
case of a young girl who was blinded by a bb pellet. As a result of your
graphic illustrations of this tragic injury, we were able to persuade the
insurance company to increase their initial offer of $75,000.00 to
$475,000.00, just short of their policy limits.
We simply wanted you to know how pleased we were with your work which, to
repeat, was of superlative character, and to let you know that we would be
more than willing to serve as a reference in case you ever need one. Many
thanks for an extraordinary and dramatic depiction of a very serious injury
which clearly "catapulted" the insurance company's offer to a "full and
fair" amount to settle this case."

Aaron R. Larson, Esq.
|"Whether it's demonstrating a rotator cuff tear, neck movement a few
milliseconds after rear impact, or a proposed lumbar fusion, the Doe Report
represents an instant on-line database of medical illustration for
health-care and legal professionals.
Illustrations can be purchased 'as is' or modified within hours and sent
either electronically or mounted on posterboard. An illustration is worth a
thousand words, as juries perk up and look intently to capture concepts
that are otherwise too abstract. Start with good illustrations, a clear and
direct voice, a view of the jury as 12 medical students on day one of
training, and your expert testimony becomes a pleasure, even on cross
examination. An experienced trial lawyer should also emphasize these
illustrations at the end of trial, as a means of visually reinforcing key
As a treating physician, I also use these accurate illustrations to educate
my own patients about their medical conditions. The Doe Report is an
invaluable resource, and its authors at MLA have always been a pleasure to

|"Our firm was able to settle our case at an all day mediation yesterday and
I am confident that the detail and overall appearance of the medical
illustrations significantly contributed to the settlement. When we require
medical illustrations in the future, I will be sure to contact [MLA]."
