heel pain, plantar fasciitis and bone spurs

In order to feel the plantar fascial ligament, with one hand bend the big toe upwards, run your finger from your other hand along the bottom of the foot, you will feel a large cord like structure that runs from the ball of your foot to your heel. The purpose of this structure is to act like a bowstring in order to support the structure of your arch.

In the picture below, the yellow band represents the plantar fascial ligament. Notices how it attaches from the heel to the ball of the foot.

Factors such as foot structure, excessive body weight, occupations that require a lot of standing especially on concrete floors and physical activity such as participating in athletic activities can all lead to excessive stretching and inflammation resulting in plantar fasciitis type of heel pain.

The problem with most foot symptoms unlike a hand injury for example, is that it is very hard to “rest” a foot in order to allow it to get better. So every time you take a step you are reinjuring an injured area and for that reason foot injuries can take a long time to heal, especially heel pain because every time you take a step you are putting pressure on the heel.

Most people relate a similar story in that they find they have the most pain on initial ambulation such as getting out of bed in the morning or getting up from a chair after being seated for a long period of time. As they begin to walk around the pain will usually subside, to varying degrees in different people. However, many people will report that as they begin to do a lot of walking the heel will start to hurt even more.

In my experience, I have found that plantar fasciitis rarely occurs alone. When there is excessive inflammation particularly at the insertion of the ligament into the heel bone, calcification can occur and you end up with what is routinely known as a heel spur which is the classic bone spur in the foot, (although there are other types of bone spurs that occur in other parts of the foot). One could argue that this is simply an exacerbation of the plantar fasciitis.

Below is a picture of a true heel spur; a calcification of the plantar fascial ligament.

Making the right diagnosis and eliminating the factors aggravating the heel pain are essential in alleviating the problem. If my patient happens to be very much overweight or wears very flimsy shoes, the chances of success in alleviating the problem are greatly diminished unless those issues are addressed.

There are a number of ways to treat plantar fasciitis and heel spurs. Because of this, no one treatment will work for everyone. Treatment options include short term oral anti-inflammatory medication. Cortisone injections can be helpful, usually done in a series of three over a three-week period, especially if you suspect an associated bursitis. Physical therapy can be helpful. If I feel that there is also a neuroma, or pinched nerve involved in the mix, I will usually begin a series of denatured alcohol injections.

Depending on the cause of heel pain, my favorite treatment is the use of orthotics. An orthotic is a device that fits in your shoes and supports the arch and plantar fascial ligament in an effort to keep it from overstretching when you walk. I use both custom-made prescription devices and over the counter type orthotics. {see my recommended orthotic} and click here for more information on orthotics for heel pain.

When conservative therapies fail to alleviate the problem, more aggressive treatments are called upon. I have found, and the literature will bear me out that 90-95% of heel pain sufferers will respond to the conservative treatments I have discussed.

If you have reached the point where conservative measures have failed and are thinking of the more aggressive therapies I would suggest you have an MRI of the heal prior to consenting to those treatments. Other less common causes of heel pain include stress fractures of the heel bone as well as possible tears in the plantar fascial ligament, along with ruptures of the adjacent muscles attaching into the heel. Sometimes a bone cyst may be present in the heel bone as well. These should be evident in the MRI.

Within the last couple of years many who treat heel pain have started to make a distinction between plantar fasciitis, which we have been discussing and what is known as plantar fasciosis. Plantar fasciitis represents an inflammation on the bottom of the heel for which the various treatments we have already discussed, are indicated, in an effort to quiet down the inflammation and reduce pain.

If your heel pain has been present for a minimum of six months you may actually be experiencing plantar fasciosis. In this condition the pain may actually be due to scarring and fibrosis on the bottom of the heel with the brain having "given up" on creating an inflammatory response in the area. So, what happens is you are left with chronic pain, the body is not attempting to heal itself and all the previous treatments you have received, at best, are giving you temporary relief. Once a diagnosis of plantar fasciosis is made treatment is aimed at re-creating inflammation in order to "tell your brain" to start working to eliminate the problem.

Some of the newer treatments being used to create re-inflammation are listed below.

A relatively new treatment option is known as extracorporeal shock wave therapy. The science behind this is the same theory used to break up kidney stones. It is high power ultrasound directed at the site of pain. There is strict FDA regulations as to when it is indicated; basically all other options other than surgery have failed. In my experience I have seen some very dramatic results but I also must report that some patients have been no better off after the procedure. It should also be noted that the procedure is covered by some but not all insurance companies and that it can be costly if you have to pay for it out of your own pocket. Click here for more detailed information on shock wave therapy.

Another option is known as low impact shock wave therapy. Whereas the previously stated high impact shock wave is very expensive and does require anesthesia, low impact shock wave therapy is far less expensive (because the machinery is less expensive), does not usually require anesthesia, but may require 3-5 treatment sessions in order to work. It too is a non-invasive therapy like high power shock wave therapy and is usually performed right in the office.

A second option for plantar fasciosis is platelet-rich plasma therapy (PRP). The patient's blood is drawn and spun down creating a small amount of platelet rich material. This material is then injected into the heel at the site of most pain. Some doctors will inject it under ultrasound guidance. There is a often a short lived pain experience by the patient due to the amount of inflammation that is created. That and the fact that blood has to be drawn and that an injection into the heel has to occur are the only real downsides to the treatment.

The third option for plantar fasciosis is what is known as Topaz Coblation Therapy. This is an invasive procedure that is usually carried out in the operating room under sedation. In this procedure a number of small holes are made in the area of the most pain; a needle is inserted into each hole and an electrical charge is given off. The electrical charge results in microscopic cutting of the plantar fascial ligament, an increase in blood flow (inflammation) and break up of the scar tissue that may be present. Even though this is a relatively minor invasive procedure there will be some down time following the procedure as recovery can be slow and somewhat painful.

Lastly, when all else fails, surgical intervention should be entertained. Today’s foot specialist is trained in doing both conventional large incision procedures and minimal incision procedures. Keep in mind, that surgery for a heel spur or plantar fasciitis can have a very long recovery period. The simple truth of the matter is that after surgery, every time you step on that heel you are basically aggravating the surgical site and for that reason the healing process can take a long time. Thankfully, most cases of heel pain can be resolved without surgical intervention.

posterior heel pain

The most common cause of posterior heel pain that I see is generally referred to as pump bump. Typically a woman will present to the office complaining of a sharp pain on the back of the heel just slightly off the center. There will be no history of trauma, although the patient may be required to do a lot of walking in a dress shoe. The pain will be at its worst when in dress shoes, may be less painful in sneakers and may be hardly noticeable when barefoot.

Examination of the back of the heel will reveal a slightly enlarged area that may be slightly red in color and usually very painful to touch. Not coincidentally, you will notice that the top of the patient’s dress shoe just happens to cut across the heel at that level. What has happened is that through constant wearing of dress shoes, the shoe itself has irritated the underlying bone, the bone has slightly enlarged as a result of that irritation and in an effort to protect the area of irritation, the body has formed a bursal sac which itself has become inflamed and is now a bursitis.

Below is the usual site for a ‘pump bump’ or bone spur with bursitis.

The obvious treatment would be to avoid wearing the shoes that aggravate the problem; that is easier said than done. I have been in this business long enough to know that a fashionable woman is going to continue to wear the shoes that look the best even though they might not feel the best.

That said, sometimes adding a small heel lift to the shoe will help as it may raise the heel just enough so that the top back portion of the shoe does irritate the enlarged bone and bursal sac. If the area is not too inflamed and painful, one may try some of the new gel cushions that are available in an effort to reduce friction.

From a medical stand point, short term anti-inflammatory medication may help but of course will not cure if the shoe is still irritating the area. Cortisone injections as well as physical therapy may also be effective.

In instances where conservative measures fail, the patient should entertain surgical excision whereby the overgrowth of bone is removed as well as the overlying bursitis. This is usually reserved for people who have stopped wearing the shoes that originally caused the problem, but are still having pain nonetheless. Unfortunately, many foot problems can continue to be bothersome even when the causative agent is identified and removed. (Once you have it; you have it!)

The other type of posterior heel pain that we see involves irritation of the Achilles tendon. The cause of this irritation may be due to trauma directly to the tendon, overuse of the tendon which is particularly a problem in men over the age of 40 who continue to play a lot of sports. People who have a tight heel cord, whereby it is very difficult to raise the foot at the level of the ankle, are more prone to Achilles tendon problems.

Below is a picture of the Achilles tendon.

If there has been trauma to the area it is important make sure all or part of the tendon has not torn. You should see a doctor right away, even though you may be able to walk, you may still have a partial tear. A torn Achilles tendon is a very debilitating condition.

Icing the area for 24 hours can be very helpful as well as anti-inflammatory medication. Rest would also be advised. I am not big on ice after 24 hours; I generally switch my patients to heat in an effort to increase blood flow to the area to enhance the healing.

If the Achilles tendon has been strained rather than traumatized, the above applications apply. Adding a one quarter inch heel lift can be of benefit because it will shorten the tension on the heel cord especially in those who exhibit a tight Achilles tendon. If the stain is severe enough immobilization of the ankle may be necessary.
