Hi, today i want to talk about a common cause of pain on the outside of the foot. this is a condition called os peroneum syndrome. Essentially what it is is an extra bone on the side of the foot here, right off of this fifth metatarsal bone, right at the base down here. Now, the reason some people get an extra bone down here, and it’s fairly common, about 20% of the population will have this extra bone in this region. The reason we get it is because when we’re born, this whole bone is made of cartilage. Over the first ten to fifteen years.
Alive, it fuses into one bone. sometimes though, where it fuses together. so the bone actually grows from two areas, the main area up here and the smaller area down here. When we’re kids there’s a layer of cartilage in between, that’s the growth plate of the bone. In most people, this fuses into one bone, but sometimes this is left in two pieces with a layer of cartilage in between. That is essentially extra bone off of this region. Sometimes it’s attached by cartilage, sometimes not, but when that’s present this whole area is a little.
Bit weaker than it should be. attaching into this region is a tendon called the peroneus brevis, and you can actually see that tendon attaching in right over here. It attaches there and it tugs on this area. So if you have an extra bone or an os peroneum in this region, that area is just much more likely to become inflamed. The nice thing is, when it does become painful, it’s quite easy to treat. We really want to do two things. One is to transfer pressure off of this region here and transfer it over.
Here somewhere, and the other thing we want to do is take tension off the peroneus brevis. The purpose of the peroneus brevis is to turn your foot out that way. If we put an orthotic or an arch support underneath your foot and then we wedge that orthotic a little bit this direction, that will help take tension off of that and often allow that area to heal and prevent it from returning. In some cases, that’s all we need to do. Many cases, just an over the counter arch support.
Will work. if you go to our website and do a search for extra bones in the foot, or accessory bones in the foot, you’ll find a page that recommends some specific arch supports that often work well for this. However, if that’s not enough, we may want to immobilize you for a couple weeks and let this heal, either by putting you into an ankle brace or to maybe use a walking boot if that’s still not enough. But this usually will heal nicely. Surgery is almost never necessary.
It is something that’s worth having treated professionally rather than trying to treat it yourself. If you can get rid of the pain in a week or two, that’s fine, but if it’s not better, be sure to see a podiatrist that specializes in or sports medicine in orthotic therapy, because there are some more serious problems that can act like the os peroneum syndrome. For example, this picture here does actually show a fracture of the bottom of this bone right there, and that can act very much the same. Definitely if it’s not getting.
Better, make sure to get that treated. Again, if you’re having pain on the outside of your foot, go to our webpage, do a search for either pain on the outside of the foot or a search for extra bones in the foot and you’ll find a couple pages that give you some good home treatment hints and will let you know when to see a professional.

Accessory Navicular Extra Bone on Inside of Foot Seattle Podiatrist
Hi. today i want to talk about a condition accessory navicular that can cause a lot of pain on the inside of the foot. This is your navicular bone. When we’re born this is made of cartilage. By the time we reach our midteens it’s all formed into bone. It actually grows from two places. A main growth center over here, and a smaller growth center out here. By the time we’re getting well in our teens, those two have usually fused together, but in about 10 to 15% of the population, those two never fuse together, and you end up with.
What’s essentially an extra bone over here. This is often enlarged on this side and it can often get pressure from the shoe. In and of itself, it’s really not a problem. It’s okay to have that in two pieces, but that area in between which is made of cartilage can become weak, and it makes this bone much more prone to inflammatory problems later on in life. So looking at this area here, there’s actually attachment of a tendon for the posture tibial muscle which is this one.
Right here. it’s a very, very strong tendon, it attaches in there. and if it tugs too hard on this bone, it can cause that area that’s in between that’s weakened to become inflamed. It’s most common on people whose feet are flatter than average. Because when that foot goes down, that tendon that attaches into that area pulls really hard to pull back. Again, in addition this area is often enlarged and as that foot goes down, it will shove it right into the shoe and cause pain. The biggest issue we see with this is people having.
Surgery more than they should. so they’ve got this bump on the side of their foot, they go in to a , they see that this is large, next thing you know, you’re having surgery to remove that little piece of bone. But in most cases surgery isn’t necessary. If we can do something under here to support that foot and stop it from jamming into the shoe, and you take tension off that tendon, almost always we can eliminate the pain. And the way you do that is using a decent arch support in your shoe.
This is a prefabricated arch support. many cases these work great. if you just go to our website and do a search for accessory bone or accessory navicular bone, you’ll find a list of the best over the counter devices both for athletic shoes and for dress shoes. That will take stress off that area, stop that foot from going over, take pressure off of this, and take tension off of the tendon. If that’s not enough, we can make you a custom orthotic. They tend to work better because they can form closer to the arch, and they.
Stop that foot from going down. and again they take pressure off of it, they stop it from jamming into the shoe, and they reduce tension on it so it doesn’t get inflamed. This is usually an easy problem to treat. Please go to the website, do a search for accessory navicular or accessory bone, and you’ll find a bunch of home treatment hints to treat it. If that’s not enough, find a podiatrist near you that specializes in biomechanics and orthotic therapy, and they, in most cases can help you a lot with that problem.
