Osteoarthritis vs Rheumatoid Arthritis - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: The bones of the skeletal system support the framework of the body and aid in movement. A joint is any point where two or more bones meet. Joints provide the human body with flexibility, precision, and weight-bearing capacity. The three major categories of joints include fibrous, cartilagenous, and synovial. Synovial joints are those affected by arthritis. Most synovial joints are freely movable, including the shoulders, elbows, knees, and knuckles. The two facing bones of synovial joints are linked by ligaments, covered in cartilage, and separated by a space called the joint cavity. The joint capsule filled with synovial fluid, lined with a membrane, seals the joint cavity. Synovial fluid maintains the cartilage by nourishing it and eliminating waste. Synovial fluid also lubricates the joint, allowing it to move freely. Arthritis is a general term for any disease that includes pain and inflammation of a joint. The two most common types are osteoarthritis and rheumatoid arthritis. Osteoarthritis, or degenerative bone and joint disease, is the most common type of arthritis. Weight-bearing activities and repetitive motion activities wear away the cartilage over time. The exposed bony surfaces rub together, causing swelling, pain, and limited movement of the joints. The second most common type of arthritis is rheumatoid arthritis. While the exact cause of rheumatoid arthritis is unknown, it is characterized as an autoimmune disorder by which the immune system attacks the tissues of a joint. The white blood cells of the immune system, particularly mast cells, infiltrate the tissue and release a variety of proteins, including cytokines, inducing swelling, increased vascularization of the joint, growth of the synovial cells, and production of antibodies. Like osteoarthritis, joints become red, painful and swollen. Unlike osteoarthritis, joints are afflicted symmetrically. Eventually, the articular cartilage in a joint with rheumatoid arthritis degenerates, and the joint begins to ossify. Over time, the joint can fuse and become deformed and immobilized, a condition called ankylosis. Although there is no cure for arthritis, medications directed at decreasing inflammation, can control or slow the progression of the disease. Osteoarthritis treatments include acetaminophen, non-steroidal anti-inflammatory drugs, physical therapy, exercise, weight control, and surgery in severe cases. Rheumatoid arthritis treatments include NSAIDs, steroids, and disease modifying anti-rheumatic drugs. More recent advances include drugs called biologics, medications that target specific factors, like tumor necrosis factor. In severe cases of joint damage, surgery is sometimes an option for pain relief or improvement of joint mobility. ♪ [music] ♪

What attorneys say about MLA and The Doe Report:
"We are extremely pleased with the quality of the medical exhibits and the timely manner in which they were provided. I will certainly recommend your company to my business associates who could benefit from your services. Please tell Brian Wilson [Director of Content Development, Senior Medical Illustrator] that he did an exceptional job on these exhibits."

"Medical illustrations are essential during trial for any medical malpractice case. The people at MLA have the uncanny ability of creating medical illustrations that simplify the most complex of medical concepts and human anatomy to a lay audience. The exhibits of MLA allow experts to easily describe complex concepts and human anatomy in a manner that could not be done otherwise.

In addition, their custom illustrations show in great detail the extent of injuries suffered and the devastating effects they have had on the client's anatomy. These custom illustration can show, side by side, the body before and after a catastrophic injury. The effect of this juxtaposition is unmatched by any testimony that can be adduced at the time of trial.

Even jurors after trial have commented on the ease with which they grasp medical concepts and anatomy once the MLA exhibits were introduced and used by my experts. Even judges who have "seen it all" are thoroughly impressed by the detail and sophistication of the illustrations.

I would not want to try a case without them."

"I wanted to take some time out to let you know what a wonderful job you did with the 'collapsed lung/fractured rib' illustrations. They were both detailed and accurate. My medical expert was comfortable working with them and he spent at least an hour explaining to the jury the anatomy of the lungs, the ribs and the injuries depicted in the illustrations. Needless to say, the jury was riveted to the doctor during his testimony.

The jury returned a verdict for $800,000.00 and I'm sure we would not have done so well if not for the visualizations we were able to put forth with your assistance. Lastly, my special thanks to Alice [Senior Medical Illustrator] who stayed late on Friday night and patiently dealt with my last minute revisions."

"Thanks, and your illustrations were effective in a $3 million dollar verdict last Friday."
