Dear MyRunningDoc, 

I have been ramping up my mileage as part of my marathon training. My foot has been sore and aching when I run. Someone told me that stress fractures don't normally show up on an x-ray until they start healing. If this is true, is there really any point to getting an x-ray if I think I did get a stress fracture from running too much?

Answer:
Great question!  This is a question I often hear from runners in San Francisco and Houston. Most runners are busy and don't wont to waste their time going to a podiatry office getting an x-ray of their foot unless they really think the x-ray will change what they need to do to get the foot to stop aching and  heal. (And of course, get back to running and training). But when you suspect a stress fracture, there are good reasons to get an xray.

3 reasons to get an x-ray of your foot if you think that you have a stress fracture.

The 1st reason to get an xray of your foot is to make sure that the metatarsal has not actually cracked all the way through the bone or broken into pieces. 

The 2nd reason is to confirm that the metatarsal, if it is broken, is still in a good position that will heal correctly. If the bone is moved out of place after it has broken that it will not heal correctly and will result in what doctors call a “malunion.” When the metatarsal bone heals in an abnormal position it will alter the way that forces are distributed across the ball of the foot. An unnatural distribution of forces across the ball of the foot will put other metatarsals at risk of problems later. It can also increase the chances of nerve compression that can lead to a neuroma. 

The 3rd reason to get an xray of your foot when you suspect you have a stress fracture is for peace of mind. Having an x-ray confirms that the bone is not actually broken and will not likely get worse if you are walking on the foot as it heals. A fracture walking boot is made to protect a stress fracture and allow you to walk while the bone heals.  if you have had an xray of the foot and confirmed that the bone is not completely broken, and you suspect that it is just a stress fracture, then you can treat it as such and feel confident you’re not going to make things significantly worse if you walk on the foot while protected in a fracture walking boot.

If you think you have an ankle sprain, a house call may be just what you need. Our foot award-winning foot and ankle surgeon can come right to your home or office. No need to wait for 6 hours in the Emergency Room. We can see you between meetings at work, arrange x-rays (if needed) and get you on the path to recovery. Did you know there are over 25,000 ankle sprains every day? With so many of those injured ankles showing up at the Emergency Room (along with all those with people with hacking coughs, colds and worries of swine flu) it is no wonder you might have to wait in line. Studies have shown that the average patient wait in an Emergency Room in some states is as high as 5 hours. That’s a long time to sit around just too see if anything is really broken or not.

Our ankle expert won an award from the American College of Foot Ankle Surgeons for his research on the accurate diagnosis of subtle ankle fractures. And we can bring all that expertise right to you. The good news is that ankle fractures are very rare when compared to an ankle sprain. But even an ankle sprain needs quick treatment to remove the ankle pain, swelling and bruising.

If you are a busy weekend warrior with your weekday schedule as packed as your weekend, an in-office house call by a true ankle expert might be just the ticket to get you on the road to recovery without any delays.

Hi My Running Doc!


My daughter has sprained her ankles a number of times. She keeps turning her ankles and they swell up. She also seems to have this popping and clicking sound from the ankle when she walks and it's really bothering her.
     Questions:
          Why does that happen?
          How do we fix it?
          What's the surgery that she needs 
          to cure the snapping and pain?
Thanks!

Answer: Ankle sprains are the most common musculoskeletal injury. In fact, there is no sports injury that shows up in the emergency department more often in a twisted ankle. Fortunately ankle sprains heal just fine most of the time. But in some cases there can be a significant injury to the ankle that prevents them from healing properly and causes problems down the road.

There are 3 primary potential causes of popping and clicking in the ankle that might be associated with persistent ankle sprains and chronic ankle instability.
1. Torn Peroneal Retinaculum
2. Lateral Process Fracture of the Talus Bone
3. Osteochondral Lesion of the Talar Dome

One common cause of popping and clicking in the ankle is fromdislocating or subluxing peroneal tendons. The peroneal tendons run down the back to leg behind the fibula. They turn around the end of the fibula as they curve down toward the outside of the foot. 

There is a thin band of tissue called the peroneal retinaculum that holds the peroneal tendons in place behind the fibula. In some cases involving ankle sprains, the peroneal tendons actually fire so hard to try to keep the foot under the leg when you roll the ankle that the perineal retinaculum actually gets torn off of the fibula bone. Because it is torn, the peroneal tendons are not held firmly in place behind the fibula.

When this occurs, the peroneal tendons are free to slide forward over the leading edge of the fibula bone. As the tendons snap back and forth across the fibula, they cause a popping and clicking sound and/or sensation as you walk. When this occurs it is not always painful but it certainly can be painful. It is more worrisome if it is painful simply because this might signify a tear or a split in one of the peroneal tendons.

If one of the peroneal tendons is torn or split it might need a platelet rich plasma injection (also known as a PRP injection) to help stimulate healing. If the torn peroneal tendon cannot heal on its own, it might require surgery to sew it back together. In any event pain in this area should not be ignored.

Another cause of popping and clicking in the ankle can be a misdiagnosed or undiagnosed lateral process fracture of the talus bone. The talus bone is the bone that connects the top of the foot to the bottom of the ankle. Lateral process fractures are sometimes referred to as snowboarders fractures.

We used to think that lateral process fractures were a rare occurrence. However Dr. Segler led a team of investigators through the largest study ever completed on lateral process fractures of the talus. He and his team won an award from the American College of Foot and Ankle Surgeons for this research. What his team found was that these fractures are about 10 times more common than previously thought. They just get missed all the time.Is

Lateral process fractures are frequently misdiagnosed as ankle sprains. Yet a broken bone does not generally heal the same way as a torn ligament. If not treated correctly, the broken bone can develop into a nonunion where the bone actually never heals. When this occurs, there can be continued pain and swelling in the ankle. Sometimes there can be a popping and clicking sensation as well.

The third potential cause of popping and clicking in the ankle after an ankle sprain is an osteochondral lesion of the talus. An osteochondral fracture is a crack in the bone underneath the cartilage. Basically what happens is the ankle rolls and the talus bone can tilt so far that the corner of the talar dome smacks into the tibia bone or fibular bone. If the talus has a hard enough impact as it twists, it can crack the bone and damage the cartilage. 

Sometimes the cartilage and the fractured piece of bone (known as an osteochondral fragment) can become loose. If not treated correctly this may not heal. If the cartilage is loose and has a flap of tissue that flips back and forth it can cause a clicking or popping sensation. This is often associated with swelling and pain in the ankle.

If there is popping and clicking from the ankle, but no history of a serious ankle sprain, the shape of the fibula can potentially lead tosubluxing peroneal tendons. The retinaculum might actually still be intact but because there is not a very deep groove in the back of the fibula the peroneal tendon still slide back and forth causing a popping and clicking sensation at the side of the ankle. This can causeperoneal tendinitis.

If this is the case, it is possible to perform surgery to deepen the groove at the back of the fibula in order to help the peroneal tendons stay in place. This will stop the popping and clicking and prevent chronic irritation of the tendon that can lead to tears in the peroneal tendons.

Another related issue with chronic ankle instability and persistently weak ankles is that the ankles can get sprained over and over. If you often find yourself rolling your ankles when walking on uneven surfaces or running on trails, the first step would be physical therapy or a home rehabilitation self-treatment program to try to strengthen the ankles and restore stability.

In some cases of chronic ankle instability the ankles are so weak that the ligaments on the outside of the ankle need to be surgically repaired or rebuilt. 

In any case, if you have popping and clicking, especially associated with pain and swelling of the ankle, it shouldn't be ignored. Get it checked out right away.

Custom orthotics are simply the best way to correct subtle imbalances in the foot and ankle that can lead to running injuries. A custom orthotic is not just an arch support or a custom foot bed with extra cushioning.  A custom running orthotic is a completely custom made medical device designed to control abnormal motion, correct for alignment problems and correct faulty biomechanics that can lead to running-related injury. 

When a sports medicine specialist performs your biomechanical exam, the sports medicine doctor takes numerous measurements of of the positions and angles of the feet, ankle and legs. Based on all of this information, the podiatrist makes a plaster mold of the feet and writes a prescription for the orthotic fabrication. The orthotic lab uses all of this to create an exact replica of your feet and then custom forms the orthotics device that will correct any problems in alignment.  This can help to increase your running efficiency and decrease the risk of running injury.    

The biggest problem for many runners in Houston is that there isn't a lot of time to waste. Because our sports medicine podiatrist is an active 11 time Ironman triathlete, marathon runner, father and busy professional, he sympathizes with the common plight of the busy Houston Area athlete. For this reason his practice is dedicated exclusively to house calls for runners in the Houston Metro, Inner Loop, Montrose, Galleria, and Houston Heights.

If you need custom orthotics, he will come right to your home or office to perform your biomechanical exam and cast you for your custom running orthotics. He will even personally deliver the orthotics to you. That way you won't have to skip a business luncheon or afternoon run just to see an expert.  Let the expert come to you!

Hi “My Running Doc!”


I recently read the book “Born to Run.”  after reading it, I became intrigued and have decided to try some minimalist running shoes. However a lot of stuff that I read online says that might get injured if I run barefoot or in minimalist shoes. 


As a little background, I am experienced marathon runner and have been running for decades. I have a neutral foot type and never had any serious running injuries. 


Do you have any recommendations on how to safely choose minimalist running shoes so I can run with a more natural running form to convert to more of a minimalist style?


Thanks!

Hello Peter,

Great question!  There are a number of different types of minimal running shoes that  you can choose from.  But before you can make a reasonable choice on which you would be right for you you have to understand the basics of “minimalist shoes.”

I define a minimalist running shoe as one that has lightweight construction, minimal support and a decreased forefoot to rearfoot drop. 

In case you’re not familiar with minimalist running shoe construction is important to point out that the “ forefoot to rearfoot drop” is the difference in height of the heel as compared to the forefoot. Standing barefoot is a 0° drop.  A running shoe with a zero-degree drop is flat. Any shoe that has no more supporting material under the heel than under the forefoot will have a 0° drop. 

A standard running shoe has a 12 mm drop. This means that there is 12 mm of material under the heel, lifting the heel up relative to the forefoot.  Proponents of minimalist running argue that all this extra material under your heel is what forces you to land as a heel striker when you run in these type of running shoes.

Vibram FiveFingers® are the shoes that many people think of when they hear about barefoot running.  The argument for this type of shoe is that you get the most sensitive ground feel, and hence a running experience that is the most consistent with true barefoot running. However you are protected by a pliable rubber outsole. These shoes certainly fit the criteria of a minimalist shoe in that they have very little support, they’re very light weight and they have a zero-degree drop (meaning the heel is no higher than the toes.) 

Given that most people are accustomed to walking and running in shoes that have a slightly elevated heel, they can at risk of injuries like Achilles tendinitis and even potentially stress fractures if they switch to rapidly to a barefoot running style.

There are other shoes however which will help you learn how to run without the drastic change in forefoot to rearfoot drop.  Another extremely  popular minimalist running shoe is theSaucony Kinvara. The Kinvara has a 4mm drop, is very light (7.7 oz.) and is very supple.  it allows a good ground feel and lends itself the natural running form however it still maintains a modest amount of support. It allows a bit of insurance in the sense that if reform starts to fall apart and you begin to convert into a heel striker you at least have some cushion to protect you.

Another good option is Newton Running shoes. Newton’s are unique in that they have elastomeric lugs under the forefoot that help encourage you to land as more as a forefoot or midfoot striker.  For a neutral runner like yourself, the Newton Gravity Trainer would be a good choice. It weighs 9.1 ounces and has a 3mm forefoot to rearfoot drop. Newton running shoes are designed specifically with the intent to help runners learn how to convert to more of a natural running style. In fact Danny Abshire, the founder of the company is also authored a book which helps teach runners to convert their running style away from heel striking to potentially more efficient stride. 

I think Danny has the right approach. I myself run in Newton running shoes for speed workouts and for tempo runs.

However I also incorporate a couple of different kinds of running shoes based on the workouts that I am doing. I run in Kinvaras for some moderate runs.  I also run a more of a typical cushioning type of running shoe when I do long runs, or any run where I expect that I might walk. Reason for this is simple. Most people it is spent their lives in elevated heel shoes can develop a tight Achilles tendon. Walking in shoes with a 0° drop can lead to Achilles tendinitis quite rapidly. As someone who trains continually and almost always has an Ironman on the schedule I can afford to develop any issues. I consider using multiple types of running shoes as cross training for my feet. I believe it decreases the risk of injury.

If barefoot running form is a new adventure I hope you will find it to be helpful in developing a more efficient stride and ultimately a more enjoyable running experience.
