Sciatic Nerve Graft

Top 3 Exercises For Herniated Discs

A great exercise for disc herniation especiallyif the person has symptoms down the leg is a prone prop. A prone prop is laying onyour stomach propped up on the elbows. We hold this position in the for 2 minutes.Pretty simple. If this is too difficult and it is too much extension, too much bending backward,here is what we can do. Same idea here. We are propping up on a pillow. We arenot neutral. We are slightly beyond that. Same idea. What we are doing is we are compressingthe disc moving it forward away from the nerve relieving the symptoms downthe leg. Normally what will happen is if the person has symptoms into their lower leg andit moves forward in this direction, that is

called centralization. That is exactly whatwe are looking for. The next exercise is the prone press up. Itis a press up from the stomach position. You are going to start right here. Keep yourwaist and legs flat on the table. You are going to press up here, Becca. Hold that fora second or two and them back down. In our , we hold it at the top for 5 secondsand go up to 20 repetitions. We do it 20 times. The modification for somebody who can'tgo back that far. Start right here and press up halfway then back down. You can doit like that or you can put your hands forward and press up. Same idea just limitingthe range of motion. But as you are

doing this, if it is the right exercise foryou and you have symptoms in your leg, you should feel it moving towards your back. Whenyou don't have symptoms in your leg and they are only your back, you are doingthe right thing. For people who work all day long and theyhave a disc herniation, this is a great exercise that they can do throughout the day.What you are going to do is you are going to stand like this with your hands onthe low back, bend back and back up. The modification is you can put your hands onthe wall and do the same exact thing. Your hands would be on the wall like this, doingthe same exact thing. Take your belly button

towards the wall.

3DPrinted Guide helps regrow complex Nerves after injury

A team of researchers from various universitiesin U.S has developed a firstofitskind, 3Dprinted guide that helps regrow both thesensory and motor functions of complex nerves after injury. The groundbreaking researchhas the potential to help more than 200,000 people annually who experience nerve injuriesor disease. Nerve regeneration is a complex process. Becauseof this complexity, regrowth of nerves after injury or disease is very rare Nerve damage is often permanent. Advanced3D printing methods may now be the solution. The researchers used a combination of 3D imagingand 3D printing techniques to create a custom

silicone guide implanted with biochemicalcues to help nerve regeneration. The guide's effectiveness was tested in the lab usingrats. To achieve their results, researchers useda 3D scanner to reverse engineer the structure of a rat's sciatic nerve. They then useda specialized, custombuilt 3D printer to print a guide for regeneration. Incorporatedinto the guide were 3Dprinted chemical cues to promote both motor and sensory nerve regeneration.The guide was then implanted into the rat by surgically grafting it to the cut endsof the nerve. Within about 10 to 12 weeks, the rat's ability to walk again was improved.Scanning and printing takes about an hour,

but the body needs several weeks to regrowthe nerves previous studies have shown regrowth of linearnerves, but this is the first time a study has shown the creation of a custom guide forregrowth of a complex nerve like the Yshaped sciatic nerve that has both sensory and motorbranches. The exciting next step would be to implantthese guides in humans rather than rats In cases where a nerve is unavailable forscanning, the researcher said there could someday be a “library� of scanned nervesfrom other people that s could use to create closely matched 3Dprinted guidesfor patients.

Helping the body regrow nerves Science Nation

♫MUSIC♫ MILES O'BRIEN: Combat, cancer and accidents all can cause devastating nerve injuries. Sometimes, the body heals on its own. CHRISTINE SCHMIDT: Your peripheral nerves are the ones in the arms and the face, have an inherent ability to regenerate but only under ideal circumstances. MILES O'BRIEN: With support from the National Science

Foundation, University of Florida Biomedical Engineer Christine Schmidt is working to restore nerve function when injuries are more complicated. SURGEON: Took that muscle and rotated it, took it over the back of his elbow to cover – MILES O'BRIEN: Surgeons can sometimes move a nerve from one part of a patient's body to another. Schmidt has developed a method that grafts cadaver tissue onto the damaged area to

act as a scaffold for nerves to regrow themselves. CHRISTINE SCHMIDT: Basically what we're doing is removing all the cellular material that would cause rejection but leave behind the native architectures. You're putting this graft into the site of injury. And now, that graft is providing a scaffold for your blood vessels to grow in. And then once you have that recellerization your nerve fibers can then regrow, so then, ultimately regain that muscle function.

MILES O'BRIEN: Navy Veteran Edward Bonfiglio, wounded in Afghanistan, faced the prospect of an amputation. A graft was a welcome option. The company, AxoGen, distributes the grafts, which were developed based on work done in Schmidt's lab. JILL SCHIAPARELLI: And his family pressed the s to say, quot;Are there any alternativeséquot; He was a young, healthy, vibrant guy. And they had a great surgeon at Walter Reed who was willing to work with them to find those options.

CHRISTINE SCHMIDT: This is some of the micronized nerve that you're working with. MILES O'BRIEN: Schmidt and her team are also looking at other approaches to directly stimulate nerve growth using natural sugar molecules found in the body as building blocks, eliminating the need to transplant tissue. CHRISTINE SCHMIDT: So you don't have to actually take it from somebody's body. You can grow it.

MILES O'BRIEN: While the ultimate goal in nerve regeneration is reversing paralysis, Schmidt says intermediate successes, like improving lung or bladder function, can be invaluable to patients and their families. CHRISTINE SCHMIDT: So rather than saying we're going to try to tackle this humongously complex beast and try to get the patient to necessarily be exactly like they were before, why not provide some function that will have merit
