Undiagnosed Achilles Tendon Tear

When an Achilles tendon ruptures, the patient may tell you they heard a sound like a gunshot and they cannot walk, but with an Achilles tendon tear it is still possible to walk around without knowing your injury.

This week a lady consulted me complaining of pains at the back of both heels and into the calves, which had been there for more 6 weeks. She experienced aching, throbbing and a stretching sensation, especially in the evening. She felt less pain wearing higher heeled shoes. In addition, the pain was worse when she got up after sitting for some time.

There was a history of a right ankle fracture and some persisitent left knee pain. She  also told me that she had been diagnosed with calcaneal spurs many years ago. The lady was overweight and of short height.

During my examination, I could see and feel that both Achilles tendons were swollen and had nodules in them. Her walking stride was short and stamping. There were other significant biomechanical problems too.

Temporary treatment consisted of  in-shoe wedging. I also referred the lady for an ultrasound scan of the Achilles tendons.

Two days later the scan reported the left tendon as having “….an almost full thickness intra-tendon tear ……approximately 2.8mm thick, extending 30mm longitudinally.” On the right “……loss of fibrillar pattern, consistent with fraying.”

There were other features, but this was one lucky lady, because there could have been a rupture at any time. This time she was referred to an orthopaedic foot surgeon.

So whether you are a patient or podiatrist, when managing chronic pain at the back of the heel, consider the benefits of ultrasound scanning to assist in diagnosis and always act quickly, you might discover an Achilles tendon tear.

702 Walk the Talk – footwear

Choosing the correct footwear for walking is very important. With the Talk Radio 702 Walk the Talk coming up this Sunday 26th July, there will be 50,000 people strolling, walking, meandering, marching and even racing through the streets of Johannesburg.

The most important thing is to keep to the footwear that you have been  using, don’t treat yourself to a new pair of trainers for the day, because although they may feel quite good at first, they need a bit of wear to ‘bed in’.

I suppose that there will be some serious hikers/walkers in the race and they will know that the best footwear is your regular well worn (not worn out) footwear. If you are walking, just for fun,  in your old worn out trainers, you might be better to walk in your most comfortable more formal shoes!

A firm but cushioning sole is best. Firmly laced, not too tightly, because your feet will swell a little and if laced too tightly, the lacing and tongue will press on the nerves on top of your feet, making them numb or tingly.

If you do get these symptoms, stop and re-tie your laces, rather then get pain. The fit around the heel must be close, so that there is no excessive sliding of your foot, because excessive sliding or shearing causes blisters.

Choice of socks is very personal. Thick or thin they should be able to absorb some of the sweat that you are going to shed. It’s worth using a thicker cotton sock rather than a woollen one.

Although many walkers and runners use no socks or even the feet out of stockings, again use what you are used to.

If you have been getting blisters during your preparation for the race, try putting a ‘blob’ of Vaseline over the place that blisters, it works as a lubricant and will reduce the risk of blistering.

An alternative is to cover a sensitive area with plaster, just beware of putting it where it could roll up and cause a sore spot.

Tactically, watch out for getting sucked along at a faster pace than you want to, or are able to go. This is one way to pick up an injury and get painful feet. You must try to keep to your own pace.

After the race, if you have blisters or any foot problem, look out for the University of Johannesburg Podiatry Caravan and treatment area, they will be able to help with most foot problems.

South African Podiatry Association

The Biennial Congress of the South African Podiatry Association took place this last weekend.

The first two days were a Biomechanics Boot Camp taught by renowned Australian podiatrist Craig Payne and today there were presentations by local podiatrists on rheumatology, diabetes, paleo-anthropology and education.

Most podiatrists  routinely perform biomechanical examinations on their patients – but this Boot Camp was something else – it has changed my thought paradigms and will alter the way I examine my patients and any orthotic treatment I decide to use. (I know this is true for every one else who attended the Boot Camp).

There was another interesting development at the Congress, I was elected Chairman of the South African Podiatry Association for the next two years.

This is a real privilege and challenge as podiatry in South Africa needs to have a much higher profile and take a more prominent place in the South African health care scene.

Expect to see much more about feet and foot care in the future.

Prevent a fall-visit your podiatrist

Many older people suffer a fall with consequent injury such as a fractured  shoulder, wrist, hip, ankle or foot. In the UK there is an active falls prevention initiative, promoted by the National Health Service.  Not so in South Africa, although we are aware of the problem.

Have you ever thought how the state of your feet could contribute to a fall? Podiatrists should be  involved in preventing falls and your visit to one could help to prevent one.

Hazel Tomkins, a British podiatrist, writing in Podiatry Now has detailed how your feet can cause a fall.

So, if you want to stand on your own two feet here’s what to look out for.

Any corn, callus, ulceration, painful nail condition alters the way your foot hits the ground. This usually makes walking uncomfortable and unsteady. With age, the cushioning fatty pad on the soles  of the feet thins out – giving less protection to the bones and joints underneath.

Changes to the basic shape of the feet alters the ability to walk evenly. Often the cause of these changes is reduced muscle strength. On the other hand, any change in posture – quite common as we age – is associated with weakening of our muscles, so there is the potential for loss of balance or unsteadiness.

Watch out for changes to the length of your legs after hip or knee replacement surgery. The pain has gone but you really do need to do all the physiotherapy to restore muscle strength and balance.

At the same time there are many changes to hearing and eyesight which affect the ability to balance and see clearly what is going on around us.

If you have any nerve changes associated with diabetes (neuropathy), you are disadvantaged, because you have a reduced ability to respond to the sensory stimuli around you. On the other hand, arthritis can cause deformity as well as stiffness, making movement difficult, slower or unsteady.

Research into barefoot walking showed a 19% worse performance when barefoot compared with even a least unstable shoe. Going barefoot or stocking feet dramatically increases the falls risk.

Simple you might think, I’ll wear slippers or shoes. Well this is an area of some dispute. There is good scientific evidence that if you change to a lower or flat heel after a lifetime of wearing high heels, you have a greater risk of falling! At the same time there is research which suggests that the most important feature of footwear in preventing falls is the grip of the sole on the ground. Added to that is the need for good fit and thicker soles.

So what to do?

Keep mobile – exercise regularly – start walking, even if you use a walking aid. Maybe you need to start using one? Make sure that you can see and hear as well as possible.

A visit to a podiatrist for a biomechanical assessment is an important way to identify any underlying structural and functional problems. Treatment of any painful foot condition, such as corns and calluses, is essential and  information on the best shoes for you, will be provided.

Avoid higher heels, barefoot walking and slippers. Consider wearing trainers with a rippled sole. A word of warning though, some trainers have really ‘grippy’ soles and that can cause a fall!

Try to remove all loose carpet runners and potential hazards that you could trip over. Make sure the lighting in your home is adequate (most falls occur at home!).

It takes team work to prevent falls, so get any advice that you can, or share it with those who you know are at most risk of a fall.

Ingrown Toe Nails

More people are complaining about their ingrown toe nails as winter comes and closed shoes are being worn more.

The most common cause of  an ingrown toe nail is poor self-treatment, but  there are numerous other factors, divided into intrinsic and extrinsic.

Common intrinsic(internal) factors are the basic shape of the nail – especially at the edges – we all have different curvatures and angles and some nails have increased curvature  on one side only.

Another factor is the structure and function of the foot (the biomechanics). If a flexible foot rolls or flattens excessively toes can rub against each other, causing pressure. Other factors can be sweaty feet and thin skin, caused by age, medication or circulation.

However, it is the extrinsic factors that really produce the problems – poor self-cutting and shoe pressure top the list. (Sometimes even health care professionals and therapists can cause ingrowns!),  tight socks and injuries can also be added to this list.

In the clinic, the appearance of  ingrown toe nails varies from a small pink swelling, to an inflamed growth or ‘proud flesh’, like a small cherry, lying over the nail plate. The pain seems to depend on the individual’s pain threshold more than the condition itself.

The offending nail can be just a small ‘shoulder’, pressing into the sulcus or a sharp spike of nail which penetrates the skin. The skin tries to heal itself when a spike penetrates it and that process leads to the formation of ‘proud flesh’ or hypergranulation tissue. Of course if the toe becomes infected then pus is also present.

Treatment for ingrown toenails varies with the cause and duration. The simplest treatment is correctly cutting out the offending portion of nail. In the more painful and complicated cases this is done under a local anaesthetic.

The permanent solution under local involves an operative procedure where the complete side of the nail including the matrix, is cut out and the matrix space is destroyed with a strong caustic. After about a month the side where the nail was looks normal – the cavity heals completely. This is a procedure that podiatrists do very well as an outpatient procedure.

Obviously avoiding  ingrown nails is the best, but nobody should suffer with them when skilled podiatric care is available.

Traction Apophysitis and Heel Pain

Heel pain as a result of [Traction Apophysitis->@case-histories] is usually debilitating. I wrote about this on 3 April, 11 February and 8 February. The progress report and full case history is now on the website under [Case Histories->]. Although this section is of greater interest to other health professionals, have a look at the X-ray pictures.

They were reported as normal – we could debate that – but what IS important is the improvement in the state of the bone after 3 months of care.

MAY IS WORLD FOOT HEALTH AWARENESS MONTH

May is World Foot Awareness Month – Diabetes & Crocs

Foot Health Awareness is vital for people with diabetes.

PEOPLE WITH DIABETES ARE 25 TIMES MORE LIKELY TO LOSE A LEG THAN PEOPLE WITHOUT THE CONDITION

Today I want to issue a timely reminder to people with diabetes who want to wear ‘Crocs’.

Last Friday, I saw a patient who “lived in her ‘Crocs’.” That was until she got splinters which penetrated the soles and stuck into her big toe, as she was walking across the university campus. The splinters were removed by her GP and today she told me there was a small remaining piece that also had to be removed. Fortunately, although she has neuropathy, the wounds are healing well.

Last Christmas, a family member (with no diabetes) also had a piece of metal go through the sole of  his ‘Crocs’, whilst walking across the garden.

Previously, I have not taken a strong stand on this, but these two events have prompted me to express my opinion in the form of a WARNING.

If you have diabetes, think very carefully about wearing ‘Crocs’. If you have poor circulation or reduced nerve sensation; do not wear them outside the home.

EVERY 30 SECONDS A LOWER LIMB IS LOST TO DIABETES SOMEWHERE IN THE WORLD

Closed Kinetic Chain Exercise for Joint Rehabilitation – Jump for Joy!

Closed Kinetic Chain Exercise for Joint Rehabilitation was the title of a Rehabilitation Workshop that I was invited to yesterday. It took place at the University of the Witwatersrand Sports Science Institute and introduced  me to Reboundology and a quite extraordinary piece of kit called Kangoo Jumps.

Kangoo Jumps are a Swiss designed boot that almost defies description – the nearest that I can come to is – a Ski boot with an oversized doughnut lying on its side as a sole!

They have the ability to reduce the impact force to the ground by up to 80%. This patented Impact Protection System utilises the principles and practice of closed chain kinetics.

Basically, the difference between open and closed chain kinetics is that in open chain there is still some movement in part of the limb, this allows additional twists or rotations to affect other body parts. In the closed chain, the part is stabilised (eg foot or hand) against a hard surface. It’s actually more complicated, but this is what I understand at present. 

Rebound exercise is different due to the following factors: During rebound exercise; We are opposing gravity and acceleration: Acceleration in the vertical plane develops a greater G-force: All these forces come together at the bottom of the bounce: Cells have to work harder to maintain their position in space: This explains why trampolinists have extra unexplained strength.

Kangoo Jumps utilise these principles by allowing you to jump up and down, whilst concentrating your body weight through your centre of gravity.

I was able to test the theory in practice when we were put through an exercise session. I had a great time bouncing around the gym, being guided in various exercises. The first thing I became aware of was that my posture improved immediately, I stood up straighter and my core lower abdominal muscles were getting a workout! My heart rate went up quite quickly too. In addition, yesterday and more importantly, today, I don’t have any muscle soreness or stiffness.

Where you will be asking is the Science? There have been many studies worldwide, but there is ongoing research underway at the University of the Witwatersrand. Have a look on the website www.kangoojumps.co.za

Reboundology has also been the subject of considerable research by N.A.S.A

The application of this technology is for rehabilitation as well as strengthening. (You would be surprised who is using them!) For example they will improve balance, co-ordination and agility; improve foot alignment; increase overall muscular tone. They stimulate cellular bone rebuilding ability. The potential application in managing arthritis is an exciting thought.

Closed chain kinetics using Kangoo Jumpssseems to me to be offering a new clinical modality and challenge to our current way of thinking. You can be any age from 6 to 90! I can’t wait to start rebounding!

May is World Foot Health Awareness Month: Baby Walkers

Today’s Foot Health Awareness Tip:  Avoid Baby Walkers.

Children will decide to walk independently when their bodies are able to. Baby walkers place extra stress on joints before nature intended. In addition they cause the foot and lower limb  to move in an unnatural walking pattern.

Research has shown the use of baby walkers is associated with a delay in normal walking and activites such as standing and crawling.

Their use is best avoided – they are banned in Canada.

May is World Foot Health Awareness Month

The International Fedaration of Podiatrists, headquartered in Paris, France, has declared May to be World Foot Health Awareness Month. I join them in calling the attention of the public and health care providers to the importance of good foot and ankle care. It’s time for all South Africans to stop and take a look at their feet!

The importance of good foot health and the role played by the podiatrist cannot be overstated, since, most South Africans will develop some foot or ankle problem during their lifetime. World Foot Health Awareness Month is a marvellous opportunity to stop and consider the value and importance of our feet.

Winter is nearly here and we will be spending more time in closed shoes. Do last year’s boots really still fit? Are they going to cause pressure calluses?

Don’t wait for your foot problem to become severe. Remember that the average person takes about 8,000 to 10,000 steps per day and while you’re walking, your feet are taking a pounding; often enduring more than your body weight with each step.

As part of World Foot Health Awareness Month 2009, there is a special focus on Diabetes and the Diabetes Health Care Team. In support of this initiative, the South African Diabetic Foot Working Group (DFWG), will be presenting free patient-oriented symposia nationwide.
