Foot and Ankle Health and Surgical Advances Critical to Quality of Life for All - April 2013
Foot and ankle health can be overlooked as insubstantial to overall health and quality of life but many conditions affecting the foot can produce discomfort, limiting mobility. Pain and impaired mobility not only affects our ability to be effective in our lives, it can cause related psychological issues that affect overall quality of life.
The foot anatomy is complex and consists of 26 bones, 33 joints and numerous tendons, ligaments and muscles. Foot and ankle surgery is performed to reduce pain, improve deformity and increase function.
Whole Body Donors are helping to improve surgical techniques designed to restore alignment, reduce pain, and preserve movement of the ankle joint. Leveraging the advancements in knee and hip replacement, technology is applied to the ankle joint including advanced materials and anatomically-matched implant shapes and sizes. This type of joint replacement surgery is called: total ankle arthroplasty.
Donation is helping to improve function and quality of life for us all. Thank you donors for the gift and for supporting life through whole body donation for medical research, education and training.

Donors Help Give Hope to Folks Disfigured by Facial Trauma and Cancer - March 2013
Imagine facing the world with severe facial disfiguration due to trauma from injury or cancer. For most people the face is our window and filter to the world. It is closely tied to our sense of individuality, uniqueness, personal identity, personality, and psychological framework…it affects how we interact with the world and how the world interacts with us. (even the phrase “facing the world” directly correlates to facial interaction with other human beings)
Facial trauma, injury and deformity can be debilitating both physically and psychologically. Maxillofacial trauma is any physical trauma to the face and can involve soft tissue injuries such as burns, lacerations and bruises, factures of bone, or eye injury. Symptoms may include pain, swelling, loss of function, or changes in the shape of facial structures. Facial injuries can cause disfigurement and loss of function such as blindness or loss of jaw movement. Injury may be a result of a fall, motor vehicle accident, violence, or cancer removal procedures. Treatment often involves complicated surgery which may be life-saving and/or secondary procedures to improve facial appearance and function.
Risks associated with craniofacial reconstruction are common to all surgical procedures with general anesthesia and include bleeding, breathing problems, bruises beneath the skin, reactions to anesthesia and infection. There are other specific risks associated with each of the different types of facial reconstruction surgery as well.
Many injuries that only involve the skin and soft tissues may just require scar revision or scar camouflage techniques. More complex trauma may involve bony tissues or a combination of soft and bony. These reconstructions often require multiple operations and teams of surgeons to achieve the desired goals for both function and appearance. The ultimate goal is the best possible outcome for the patient including long term structural functionality and aesthetics.
This type of surgery is reconstructive in nature and should be performed by a plastic surgeon that specializes in this type of surgery. It is recommended that the patient seek the services of a facial plastic surgeon (as opposed to a general plastic surgeon).
Science Care medical research and training clients are currently working on facial reconstruction techniques for those who have either suffered severe trauma or have lost a portion of their face due to cancer. In a unique and transformative application clients utilize donor tissue to train doctors to perform full face transplants. Successful full facial transplants have recently been in the news. This type of transformational surgery not only provides function (where there is little to none) but can restore hope for a more normal quality of life for the patient.
Thank you donors for supporting life through whole body donation for medical research, education and training!
Transdermal Drug Delivery Systems - January 2013
What is TDDS? Think “the patch” but with the potential for much broader application.
The first adhesive transdermal delivery system (TDDS) patch was approved in 1979 for motion sickness. Nitroglycerine patches in 1981. This method of delivery became widely recognized in 1991 when nicotine patches for smoking cessation were introduced.
A transdermal patch is a medicated adhesive patch placed on the skin to deliver specific doses of medicine through skin and into the bloodstream.
There are advantages over the oral route or hypodermic injection. The patches can release the drug for extended periods of time, improve patient compliance with the medication regimen and are relatively inexpensive. Hypodermic injections by contrast are painful, generate dangerous medical waste and pose the risk of disease transmission by needle re-use. Additionally, transdermal systems are non-invasive and can be self-administered.
Key point: Only molecules small enough to penetrate the skin can be delivered by this method.
A wide variety of pharmaceuticals are now available in transdermal patch form. But before these patches go to market, they must be carefully studied.
This is where Science Care donors become critical. Donors are involved in the research, development and testing of these types of transdermal technologies. Without donation, the speed at which these advances in treatment options and the impact to patient quality of life today, would not be possible.
Robotic Assisted Surgery - September 2012
One way that donors are able to directly impact healthcare is through the development of novel medical devices involving robotic assisted surgery and surgeon education. The goals are to improve overall quality of treatment utilizing a minimally invasive approach as well as the capability for remote distance surgery. This work leads to increased accuracy, shorter hospital stays, faster recovery times and improved quality of life for patients.
Why the emphasis in the last 20 years on the development of more minimally invasive surgical techniques? What does it mean for me?
Basically, this method of surgery involves less trauma to the tissues which in turn means that the patient experiences less pain and reduced downtime. There are several benefits to this, some obvious and others not so obvious:
•Less pain, less reliance on pain medications, easier and more successful rehabilitation
•Reduced risk of side effects such as scarring and infection
• Improved quality of life achieved more quickly
• Less time spent under expensive hospital care
Why robotic assisted surgery? Is this actually an improvement?
This is one of the newest developments on frontier in the minimally invasive surgical technique tool box. There are pros and cons to all surgery so talk with your doctor candidly about your concerns. In general:
• The robtic tools are simply implements that allow the surgeon to be able to be more effective or precise
• Often the use of robotic equipment allows the surgeon greater range of movement while working in a very small space
• Possible decreased blood loss and smaller incisions
Science Care donors directly impact the improvement of these devices and techniques and help to train surgeons. Whole body donation improves the lives of everyone!
Back Pain Helped by Whole Body Donation - June 2012
Some sobering statistics about back pain:
• Lower back pain is the second most common reason for visits to the family physician, behind only the common cold.
• Back pain affects more than 80% of people in the United States.
• The most common cause of lumbar back pain is normal degenerative arthritis: the wear of cartilage over time.
The good news is that there are various treatment options for back pain, including medications, physical therapy, or injections. Most people (90%) will see improvement within six weeks regardless of the method of treatment. But the other 10% may become candidates for surgery. Lumbar spinal fusion is one of the most common lumbar spine surgeries used today by surgeons and there are over 200,000 performed each year in the U.S.
Science Care whole body donors are involved in lumbar spine fusion by way of helping to develop and improve minimally invasive options for surgery. Minimally invasive lumbar spinal fusion is similar to the traditional, but it uses much smaller incisions and results in significant benefits to the patient.
For background, lumbar spinal fusion is an operation that causes the bones of the spine in the lower back to fuse together. The goal of the surgery is to have two vertebrae fuse together so there is no longer movement between the vertebrae, which is typically the cause of the problem. The minimally invasive surgery can be done through the abdomen, from the back, from the side, or with any combination of these.
Science Care donors are contributing to training surgeons on the actual minimally invasive procedure, which allows surgeons the opportunity to increase their knowledge of the procedure and the ability to test new techniques. Minimally invasive surgery results in many benefits to the patient, including less damage to the surrounding tissue, reduced recovery times, less pain, reduced blood loss, reduced need for blood transfusions, shorter hospital stay, and less need for narcotic pain medications.
The 30-Year Knee Replacement - May 2012
Total knee replacement is among the most common surgery performed in the United States, with over half a million patients enduring surgery each year. Traditionally, a knee replacement would last about 10-15 years, but new customized knee replacements can last three times as long, up to 25-30 years.
Science Care whole body donors contribute to research to develop and improve customized knee replacements. The research includes training surgeons on the actual implant procedure,allowing researchers the opportunity to better fit the devices and test new techniques of implantation.
A customized knee replacement is no easy task because no two patients have exactly the same anatomy. Customized devices are designed to fit each person uniquely, and the process involves making a 3-D model of the patient’s knee, taking into account the bone structure, alignment, and even gender and age. Bio-engineers then use that 3-D model to create a personalized mold for the knee implant.
In addition to the device lasting up to three times as long as before, customized knee replacements have additional benefits to the patient and the surgeon:
- Reduced recovery times
- Less pain
- Decreased infections
- Reduced blood loss
- More precise surgery
- Surgical time reduced approx. 40%
Science Care donors’ contribution is a huge benefit to the hundreds of thousands of people who undergo this knee replacement surgery every year.
Science Care Donors Support the Gift of Hearing - April 2012
“Blindness separates us from things but deafness separates us from people.” – Helen Keller
Science Care whole body donors have contributed to research to develop and improve cochlear implants, including training surgeons on the actual implant procedure, allowing researchers the opportunity to better fit the devices, and the ability for researchers to experiment with new techniques of implantation.
Advances in computer technology and surgical techniques and devices have provided the opportunity to offer the world of sound to many people who otherwise would have spent their lives in a soundless cocoon. Approximately 38 million people have a significant hearing loss, including 3 million children. Many of them can now experience the gift of hearing thanks to cochlear implants.
Cochlear implants have actually been around since the 1960’s, but were not used widely until the 1990’s. Initially, the deaf community did not approve of cochlear implants, fearing that the technology would affect deaf culture. Today, however, cochlear implants are widely accepted and used.
A cochlear implant is a small, complex electronic device that helps to provide a sense of sound. The implant consists of an external portion that sits behind the ear and part that is surgically placed under the skin. This is how a cochlear implant works:
1. A microphone picks up sounds, and sends it to a speech processor.
2. The speech processor selects and arranges sound, and sends a signal to a transmitter.
3. The transmitter converts the signal into an electrical impulse.
4. Finally, a group of electrodes collects the impulses and sends them to the auditory nerve that the brain recognizes as sound.
Based on the success of cochlear implants, the FDA has approved implants in children as young as 12 months! Implants coupled with therapy can significantly help young children to learn speech and language skills. Today, more than 250,000 adults and children have received a cochlear implant…and with it, the ability to hear.
More than Skin Deep - March 2012
Did you know that the largest organ in the human body is one everybody can see? Skin is an extremely important organ, and it basically acts as a shield for the body. Skin guards against harmful chemicals, helps the body to prevent infection, and even manufactures vitamin D from the sun to convert calcium into healthy bones.
Science Care donors contribute skin to medical research in a variety of ways with recent research focusing on two basic categories: research to keep bad bacteria out of the body and research to allow good medicine more deeply into the body.
For the first category, researchers are looking for ways to eliminate or prevent bad bacteria from getting inside our bodies after surgeries. If there were any germs on a surgeon’s glove, on the scalpel, or even in the operating room air, those germs, or bacteria, could potentially get into the body and cause an infection. Infections are a big problem for hospitals, because a surgical incision infection is the most common disease acquired by patients in a hospital. The bulk of these infections are Staph infections (such as MRSA), which are extremely difficult to cure and can even lead to death.
Current prevention is skin sterilization on the outermost layer of skin. You’ve probably seen a doctor or nurse put iodine on the skin before a needle puncture. But what researchers are working on, with the help of Science Care donors, is a chemical compound that could sterilize much deeper skin layers than ever before which could potentially eliminate or prevent infection inside the body following a surgery.
The second category is research and development to transport medicine to the exact area of the body that needs it…not through needles or pills, but through the skin. The research centers on using trans-dermal patches (similar to a nicotine patch) which allow patients to avoid needles or oral medicine (pills) entirely. As different medications have different size molecules, preclinical testing is necessary to ensure safe effective formulations and dosages for the delivery of medication through the skin. Patches are often superior to needles and pills for several reasons: they get the medicine directly into the bloodstream in the right area of the body, they don’t break the skin, the patient has no pain, medications can be delivered in controlled doses over time, and the patient has reduced negative side effects.
By providing skin to medical research clients, Science Care donors are contributing to create a better quality of life for patients everywhere.
Making a Big Difference on a Microscopic Level - February 2012
At Science Care, we talk a lot about the types of medical research and education that you can see with the naked eye, such as developing new and better hip or knee orthopedic implants and training surgeons how to use those.
However, did you know that Science Care also works on a microscopic level? Even though some of the tissue we provide is much, much smaller than a hip or a knee, it makes a very big impact.
One example of microscopic tissue that we provide is Cerebrospinal Fluid. This is a clear liquid that is found in the area surrounding the brain and spinal cord. As part of the central nervous system, this fluid serves two very important roles in the body: a vehicle for delivering nutrients throughout the nervous system, and it acts as a shock absorber to protect the brain and spinal cord from trauma.
While Cerebrospinal Fluid is certainly important inside the body, it is equally as important outside of the body for research purposes. Research conducted with Cerebrospinal Fluid concludes that changes in the fluid can help diagnose Alzheimer’s Disease early, approximately 5-10 years before the disease presents itself. This information, coupled with current research, will likely lead to treatments and preventative measures that can be put in place long before the disease takes hold.
Currently nearly 36 million people worldwide are living with this debilitating disease. Alzheimer’s Disease International estimates this number will double by 2050. By providing Cerebrospinal Fluid to clients, Science Care is helping to advance treatment of Alzheimer’s Disease by affording medical researchers the opportunity to make discoveries leading to earlier diagnosis, better and more effective treatments, and an eventual cure.
