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.

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.

Bunion Surgery – A Painful Choice

Deciding to have bunion surgery can be one of the most difficult health decisions to make. ‘Bunions’ are a cause of distress to many thousands of people -mostly women -worldwide. Last year, I wrote about bunions and my opinion was and still is – “avoid bunion surgery if at possible, unless it is ruining your life and crippling you with pain”.

The ‘bunion’ referred to here is the bony deformity characterized by a big toe that deviates towards the rest of the toes, possibly accompanied by a second toe which is bent and overlies it.

When any surgical intervention is considered, be it the podiatrist enucleating a corn, removing part of a toe-nail or the orthopaedic surgeon realigning the foot in bunion surgery, all of us strive to do our best to achieve a satisfactory outcome, by exercising our skills to the utmost.

So you can imagine my concern to have two patients recently complaining bitterly about their unhappiness with the result of their bunion surgery. Add to this my surprise at the ‘twenty-something’ who wants surgery because she doesn’t like the look of her feet and her bunion (this one is the small thickening of the metatarsal bone with no deformity), prevents her from wearing the high fashion shoes she needs for work.

What can you say to a middle-aged, active woman who decided to have her bunion (deformed type) corrected, but after three months can only wear trainers with the toe cut out, has a swollen foot, pain and discomfort, difficulty driving, plus all the associated emotional stress? Or how do you respond to a similar woman who is now in constant pain and has had altered her walking style because the foot is rigid at the big toe joint?

To the best of my knowledge the procedures were technically successful and there is no deformity anymore. In addition we all react differently to a surgical “assault” and time does allow better healing. Also, there are numerous variations of operations and techniques available for bunion correction surgery.

Firstly – go back to the surgeon and discuss your options.
Secondly – see if a podiatrist can assist with biomechanical correction or alignment and footwear advice.

With my 2 patients, one has had orthotics made and the other I referred to the surgeon, who has recommended further physiotherapy, with the possibility of another operation to remove the steel plate that is in the foot.

I will still refer patients who meet my criteria outlined above for consideration for surgery, because the final decision to undergo sugery is always taken by the patient. Unfortunately, there can be no absolute guarantees since the structure of each foot is so complicated.

So what to do about ‘bunions’? Is there an underlying systemic disease such as rheumatoid arthritis?

We must consider the patient’s age. Is the patient overweight? What is the biomechanical structure and function, not only of the feet but lower limbs and body? Have all possible conservative measures such as night splints, orthotics, insoles, appropriate footwear, been exhausted?

Be guided by the severity of loss of function, pain, discomfort and limitation of daily activities. Will the patient be able to adhere to all the post-operative requirements, expected by the surgeon?

Eventually, all these factors (plus others), must be seriously thought about before undergoing bunion surgery.

Foot Pain & Posterior Tibial Tendon Rupture

Never ignore foot pain. A recent case of tibialis posterior tendon rupture is a case in point.

A 76 year old lady was brought to me by her daughter because she could barely walk and was in constant pain. She had been prescribed anti-inflammatories and sleeping tablets for ‘the arthritis.’

At her only previous visit to me in 2003, I had diagnosd the potential for flat foot related problems and made orthotics. The lady never kept any follow up appointments.

This time, the lady described her symptoms as “the left foot is giving me hell. Over the past year, it’s been getting gradually worse and now I can’t wear my shoes.”

When I asked about the previous treatment, she informed me that she gave up with orthotics because they didn’t fit easily into her shoes.

When I examined the foot, it was completely flat and rolled over and the arch was non-existent. The lady was unable to stand for more than a few seconds and she couldn’t manage more than two steps across the room. In addition she was unable to raise up onto tiptoe.

As I traced a path along the inside of the foot up behind her ankle to the lower part of her calf she experienced significant pain. This is the path of the Posterior Tibial Tendon, the main tendon to help form and hold the arch of the foot.

Posterior Tibial Tendon

I immediately sent the lady for X-rays and an Ultrasound scan.  The scan revealed a rupture of the Posterior Tibial Tendon.

Referral for surgery has been completed and now we wait for the outcome, except that she has developed a problem with her eyes that needs treating before any surgery can take place.

The moral of this story? Follow up is vital from both sides of the medical equation. Ignoring foot pain can have serious consequences, so managing it is a team effort.

A Sports Injury or Child Abuse?

How much sport is enough for a child? When does too much sport become abuse? Is an over-use injury at a young age, in the pursuit of excellence worth the possible long-term consequences? Consider this:

Last week, an 8 year old boy, barely able to walk, was brought to see me by his mother. He had a severe limp, walking with his foot out and his ankle stiff, to reduce the pain. Three days previously he had spent nearly 5 hours doing athletics at school. His mother told me that the initial pain began more than 6 months ago, after he had played a lot of rugby.

The school under 8 team had been very successful, winning their area age group, so had a long season. Then he moved up an age group to under 9 which extended the season further. Nevertheless he continued with all sports, despite the pain and the fact that he was not running as fast as before. A compounding factor is that athletics and rugby are both done barefoot.

The timetable of sports reads like that of a professional adult, with daily practice depending on the sport and season, with inevitable overlap; plus the fact that the school plays some sports out of season as well.

• Athletics: 1 hour a day, x 5 days, plus meetings
• Cricket: 1 & half hours a day x 5 days, plus club games on Saturdays for a university club junior side
• Rugby: 1 hour a day x 5 days, plus matches

The boy is obviously very good at his sports and according to his mother is always active at home whilst playing. However, this timetable with an injury would cripple most adults.

So what’s the point? How far must we/should we push or allow our children in pursuit of sporting excellence? We try to teach balance in most aspects of life, sleep, study, money etc., but when it comes to sport we seem to make up the rules as we go along.

After requesting X-rays of both feet and discussing them and my diagnosis with two different medical colleagues, it was agreed that the cause of the pain is damage to the growing part of the back of the heel bone, where the Achilles tendon inserts. Clinically called a Traction Apophysitis.

The initial treatment is rest and avoiding any vigorous activity that causes the Achilles tendon to pull on the heel bone. Raising the heel or possibly orthotics may help.

So ask yourself the question – is this youngster suffering an over-use injury or child abuse or both?

A full Case History will be posted during this week.

Sesamoid Fracture – A Holiday Injury

Best wishes for 2009. The first holiday injury came this week. Another sesamoid fracture . A  38 year old male patient returned to the practice for follow up to a visit in December, due to have impressions made for new orthotics.

He told me that on Christmas Eve he had slipped and fallen into a swimming pool with his  leg fully extended – ‘straight out in front and under me’. The leg had hit the bottom of the pool with the ball of his foot, jarring it severely.

Over the next few days he experienced varying degrees of severe pain, best relieved with wearing thicker soled shoes. However, with the weight off the foot there was a constant throbbing.

Remembering the young lady I wrote about about towards the end of last year, I sent for X-rays. Result a fracture shows clearly in one of the sesamoids.

Treatment? Take it easy. No excessive activity – but cycling in the gym is OK. Thick and soft soled shoes – probably sneakers. Be patient!

Sesamoid fractures should always be suspected with a history of sudden stamping under the foot. They usually heal well, but may take time.

New Year Resolution – Become a Podiatrist

In just under 7 hours time South Africa will welcome 2009. Will you make a resolution to become a podiatrist? Maybe one of your family or friends will?

Are you sitting with your ‘Matric’ results and not sure what to do next? South Africa has a serious shortage of podiatrists and as I wrote the other day even our new graduates are emigrating. There are fewer than 200 registered podiatrists for our population of about 48 million people.

However, with increasing access to health care and awareness of the benefits of a healthy lifestyle, there is a growing demand for foot care, especially for children and people with foot problems associated with diabetes and arthritis. Nevertheless, many sectors of the South African population still don’t know what a podiatrist is or what we do. As our population changes more people will need foot care.

A podiatrist is really a ‘doctor of the feet’. We diagnose and treat foot disorders and abnormalities. This is done in many ways. Biomechanical examination involves assessing the whole lower limb and its function and then prescribing the appropriate treatment to maintain or restore normal mobility or function.

Many systemic diseases affect the feet and may even be diagnosed from foot symptoms. As a podiatrist you may need to refer your patient to a specialist for further management. A large part of podiatry treatment involves the skilled use of sharp instruments to treat corns or callus or possibly perform detailed corrective surgical procedures on toe nails.

Some of the conditions that Podiatrists treat are fungal infections of the feet and toenails; corns and calluses; ingrown toenails; foot ulcers in diabetes; causes of foot pain in arthritis. Most podiatrists incorporate orthotics and insoles into their treatment when necessary. 

The assessment and management of childrens’ foot problems forms an important part of a podiatrists work, whilst some podaitrists are skilled in the managemment of foot problems arising from sports. Nowadays, prevention of foot problems has become very important, so foot health education is also part of podiatry practice.

Although there is no official specialist register for podiatrists, many of us have developed ‘special interests’ in sports injuries, chronic disease, children or the elderly.

The day to day work of a podiatrist is interesting and varied. Giving relief from pain or diagnosing the cause of a foot problem is both challenging and stimulating. You do need to be able to work alone but also need to be a ‘people person’ to relate to the different patients you meet every day. Most podiatrists are in private practice, but we hope there will be an increasing deployment of podiatrists in the State Health services in future. For example Limpopo Province appointed their first graduate podiatrist.

To practice in South Africa you have to register with the Health Professions Council of South Africa.(HPCSA). This means that you become part of the Team of health care professionals providing care to South Africans and that you adhere to ethical standards.(By the way, it is illegal to practice as a podiatrist in South Africa if you are not registered with the HPCSA. So always check the credentials of a podiatrist).

To become a podiatrist in South Africa requires four years of full-time study at the University of Johannesburg. You will obtain a Bachelors degree and be able to go into practice immediately. Although bursaries are limited I believe this is changing as Provincial Health Departments begin to realise the value of foot care. Your entrance is dependent on your Admission Points Score (APS) or your M-score.

There are still vacancies for 2009 enrolment. So why not contact the University of Johannesburg – they reopen on 5th January 2009 – at 011 559 6167 or www.uj.ac.za

However you welcome in the New Year, dancing  the night away, taking it easy at home with friends, walking on the beach on an exotic island or if you are unlucky, at work! Enjoy yourself and I wish you all good foot health and happiness in 2009.

Holidays: Sore Feet and Sunburn

Sore feet or sunburn could ruin your holiday. Whether you are going to the coast, mountains or bush, you need to pay special attention to protecting your feet this summer.

As the holiday season gets going, many of us will be exposing our feet to the African sun for longer periods than usual. Remember that if your feet are usually covered by shoes and socks, they will need as much protection as your face and shoulders. (Or your bald head). Despite the fact that we spend a lot of time barefoot or in sandals in South Africa, during holidays the time is often extended.

The most vulnerable part of your feet is the skin on top of your arches. However you can also get sunburn on the soles of your feet if you like to indulge in serious ‘sun-worship.’ Obviously any part of your feet that is exposed is at risk. Initially you might not feel too much discomfort from sunburn, but when you put closed shoes on there will be pain.

Usually, sunburn is confined to a patch of inflamed, sensitive skin, which responds to protective after-sun preparations. The end result is skin dryness and peeling after a week or so and little harm is done. In severe cases however, the inflamed area starts to blister and itch. This is when scratching or opening the blisters can lead to infection.

Always apply sunscreen on top of your feet before you go to the beach, shopping or walking. You might need to re-apply after swimming, depending on what you use, or suits you. If you are spending a long time lying face down with bare feet protect the soles. After showering, treat your feet as you would the rest of your body with your choice of after-sun preparation.

Another common holiday foot problem is burning the soles of the feet. Here again it is usually because the soles of our feet are not as tough as we think and so we forget that the beach sand burns. The same thing applies to the patio tiles or paving.

Don’t do crazy things like walking barefoot over the car park. We all know that it’s thought to be very ‘macho’, to run around barefoot on holiday, but there is nothing ‘macho’ about peeling, blistered soles.

Unfortunately wherever you are, at the beach or around the dam your bare feet are not protected from broken glass, cool drink cans, palm thorns, bits of charcoal from the braai, even rubbing from your new sandals! Watch out for those beach thongs rubbing between your big toe and second toe too.

Always wash sea sand off your feet before you walk any distance, because it can chafe and irritate skin between your toes.

You might even get painful feet from all the extra walking that you do. This can be a big problem if you are walking along a beach where the sand is rough, or if you spend time jumping around in the sea on rough sand. It can also happen if you are enjoying the sights of a chilly Northern Hemisphere winter, as you spend more time walking around.

Finally, as you lie on that soft, sandy beach preparing to enjoy the warm Indian Ocean, remember it’s not just the sharks that can get you, look out for sea anenomes, puffer fish and coral!

So just think ahead. Protect your feet and those of your family, but above all, relax and enjoy putting 2008 behind you. Don’t let sore feet or sunburn spoil your holiday, but if it does, go and see a podiatrist.

Sesamoid Fracture – an interesting case – treatment

The case of the sesamoid fracture that I referred to the other day, has had an interesting development. You will have read that we ended up using an Aircast below knee walker. Unfortunately this was only successful for about one day. By the end of the day the pain was increasing.

I advised my patient to get advice from an orthopaedic surgeon who I know. The advice was really simple! Wear thick-soled soft trainers and take pain-killers until it is better. (Obviously only take the pain-killers as often as really necessary). This will allow normal movement – remember this condition is not treated by immobilisation in a cast – but not over use.

So what’s the lesson here? Simple treatments are often the most effective. Never ignore foot pain in the ball of your foot. Have it accurately diagnosed – it might be a sesamoid fracture.

An interesting case: Sesamoid Fracture

I diagnosed a sesamoid fracture in a young woman this week. The presenting complaint, on Wednesday, was of “pain in the ball of the foot under the big toe joint for nearly 9 months, but 3 days ago (Sunday), whilst doing a long day shift the pain got really bad and only stops when I take weight off the foot.”

The ball of the foot was noticeably swollen, but not inflamed. However, when I applied light finger pressure to the area the pain increased and was particularly bad at one spot. The lady has a high-arched foot (pes cavus), but it is flexible not rigid. She is not overweight, but is very active everyday of the week -including some weekends – working long hours. She told me that she usually wears a low heeled shoe or sandal, but it had become impossible to wear slip-ons or ‘push-ins’ because of the pain. The only relief was to wear trainers with a thick sole. When the weight was removed by sitting or resting in bed there was no pain.

By applying a protective pad to the sole and the arch, with a cut-out around the painful area, painfree walking was possible. An X-ray was requested; both feet for reasons that I’ll explain shortly and a follow-up appointment was arranged for Thursday morning.

We met on Thursday and the X-ray showed a clear break in the lateral sesamoid. The pain was also worse because the padding had slipped backwards and out of position. By repositioning the pad, the pain was relieved again. I instructed her to use trainers as often as possible and suggested that she do the replacement padding herself. In addition I arranged for her to be fitted with an Aircast below knee walker, which she could borrow from the practice on Friday after work.

The treatment for this condition is mainly patience and removal of pressure. Which is why I decided on the Aircast. When we fitted the Aircast walking was immediately painfree. Now we both have to wait for the bone to fuse as one or even two bones.

There are two sesamoids under the ball of each foot. They allow a particular muscle to pull the foot down during standing and walking; they also survive a lifetime of bending at the ball (the first metatarso-phalangeal joint). In some people, one of the sesamoids is naturally bifurcate and can look as if it is fractured – called a normal variant -that is why I asked for both feet to be X-rayed. This fracture may heal in two parts also, which won’t be a problem.

Pain in this part of the foot is quite common. It is caused by excessive amount of shearing, compression or tensile stress over the joint. It can be associated with sports like golf and tennis. Starting running or training and doing too much or running in old trainers. Wearing old worn shoes, where the inner sole gets a deep imprint. It can be associated with rheumatoid athritis, or even standing on a ladder for long periods, when you aren’t used to doing that! Nearly always it affects people with a high arched foot who have over-used their feet.

Initially the bone and the joint under them become inflamed and that is called sesamoiditis. Ignore this and a sesamoid fracture may result.
