Hey everyone, this is Ruehle from AdvancedSpine Health Center in Urbandale, Iowa and today I want to talk about Sciatica. Now, this is going to be the first of a seriesof tutorials that we're going to do talking about different problems we see here in ouroffice. And really the goal of these tutorials is totalk about the causes of the causes of each one of these problems and that's what wewant to do today with Sciatica. So, what is Sciatica and how it gets its name,what are the two most common causes of Sciatica, and what the causes of those causes are, andthen what we do differently here in our office

both to treat and to prevent Sciatica. So, what is Sciaticaé So Sciatica is the impingement or irritationor inflammation of the Sciatic Nerve. Now, the Sciatic Nerve is the largest nervein our body and it runs from our low back, out the back side of our buttocks here inour pelvis, across our buttocks and down on the back side of our leg. So, the Sciatic Nerve is really a group offive nerves, all starting in the low back, and they start here with lumbar spinal nerves,the last two lumbar spinal nerves in our back

the fourth and the fifth lumbar spinal nerveand then the first three sacral spinal nerves that come from this triangle shaped bone herecalled our sacrum. The first three of those connect with thesetwo in our lumbar spine and those five come together to form the Sciatic Nerve. Now, that Sciatic nerve comes together andruns outside of this notch here in the back side of our pelvis and runs across our buttocksand down our leg, and that's usually where we get the pain when it when it's irritatedor when it's inflamed is across the buttocks and down the leg and sometimes in the lowback.

So, what are the two most common causes ofSciaticé Now, the number one most common cause of Sciaticais disc bulge or a disc herniation. Most people know what that is and you cansee from this model that this red disc herniation actually comes out and irritates or pincheson the spinal nerves so when it does that it goes down the course of the Sciatic Nerveand causes Sciatica. So, the second most common cause is calledpiriformis syndrome and piriformis syndrome is really the spasming of the piriformis muscle. So, the piriformis muscle runs from the frontside of our sacrum here, again this triangle

shaped bone, front side of our sacrum acrossour buttocks to our femur which is our leg bone so when that muscle spasms it irritatesthat Sciatic Nerve as it comes out of this notch. That Sciatic Nerve runs underneath the piriformismuscle over top of the piriformis muscle or sometimes even through it. It doesn't really matter when that when thatmuscle spasms it can irritate that sciatic nerve and cause Sciatica. So, those are the two most common causes.

Disc bulges being the most common cause andthen piriformis syndrome being not as common but another cause. So now what really causes disc bulges andwhat really causes piriformis syndrome or spasming of the piriformis muscleé So starting with disc bulges, what reallycauses disc bulgesé When you go and do a quick online search whatyou really find is people talking about water loss in age of our discs, so as you get olderyou lose the water in our discs and it shrinks and you get disc bulges or disc herniation.
