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.
Bunions create as much comment and discussion as they do pain for their 'owners'. Let's assume that your bunions are bony lumps. First ask yourself are they getting bigger and more painful? Being disappointed with the look of your feet is not reason enough for surgery. Possibly you have some underlying arthritis and the joint is painful at every movement and it is seriously affecting your quality of life. Rheuma-surgery,as it is known is becoming more appropriate nowadays. Another cause for concern is if the big toe is deviating away towards the smaller toes so much that your foot is beginning to look like a tennis racquet.
Whatever the nature of your problem, if you do decide to undergo surgery I believe there are some basic truths to come to terms with. Perhaps the most basic is the most obvious – make sure your surgeon is a specialist foot surgeon – not one who includes foot surgery with the rest of his/her practice.
Then you have to fully understand and accept the conditions surrounding the surgery. This usually includes at least six weeks of careful rest, individualised treatment and immobilisation, plus the general life disruption. It's my opinion that most "disappointing" surgical outcomes are the result of patients being unable or unwilling to fully comply with the post-operative care requirements.
So what to do about your bunions? Try every conservative measure that you can to preserve your feet. if your life has become interrupted and painful because of your bunions then DISCUSS with your surgeon all about the procedure and after care before you go ahead. Or maybe don't!
Every person who has diabetes, should have an annual foot examination. Feet, along with kidneys and eyes, form the "terrible triad" as it is sometimes called in medical circles; because people with diabetes can develop peripheral arterial disease or peripheral neuropathy(feet); nephropathy(kidneys) and retinopathy(eyes). I have spent the past two days conducting the Annual Foot Examination for people who attend the Potchefstroom Centre for Diabetes (CDE).
How many people with diabetes undergo this annual examination? Who knows? What is certain is that CDE members have to comply with rules which gives them access to all the basic health care professionals they need. (CDE is a Managed Health Care network of over 250 medical practices contracted to certain medical aid schemes).
The benefit of this annual examination is that patients, families and health carers know if the feet are at risk of developing futher complications associated with diabetes. The examination involves checking vascular, neurological, dermatological and orthopaedic status. Footwear is also checked and commented on. The International Consensus for managing the diabetic foot states that early identification of vascular insufficiency and referral to the vascular specialist does save many limbs.
Worldwide of course there is evidence that smoking damages your health, but even in the group at Potchefstroom there were smokers. All of whom had diminished circulation, plus the typical signs of cool feet, absent hair, discoloured pink/blue feet – especially when hanging over the side of the examination couch – and a cough.
Checking the state of sensation is vital for good diabetic foot health. The loss of sensation – neuropathy – is often an insidious process, not being fully appreciated by the patient until they are aware of "funny feelings" in their feet. Patients describe sensations of "pins and needles," "shooting pains," "ants running over my feet," "I thought my sock was folded over under my foot, but it wasn't," "it feels like I'm walking on cotton wool" and many others. This could be the first step to damaging the foot and developing an ulcer.
People with diabetes get all the conditions that affect the rest of us. However, if not identified and managed properly an area of callus(which indicates increased local pressure) can easily develop into an ulcer. Various nail conditions are common amongst people with diabetes, especially fungal infections and they are difficult to get rid of.
They structure of any foot affects its function and so in the diabetic foot assessment we look at the alterations in shape that could cause load increases and potential blister or ulcer sites. In addition disorders such as gout are very often associated with diabetes.
Footwear is responsible for at least 50% of foot ulcers, so this is examined very carefully. Unfortunately, many people do not have suitable footwear, so it's important to check it and give good advice.
Diabetes is a life-threatenting disease, but modern medicine has moved to early diagnosis and treatment and an important part of this is recognition by podiatrists of the signs in the feet. However for the person with diabetes one of the simplest acts to ensuring long life is to have your feet examined annually and know your foot status or risk.
Back from the AFLAR Nairobi Rheumatology Updates. Hard work, but enjoyable and successful. I presented my "Foot Problems in Arthritis" talk to the Allied Health Professional's Workshop and the formal Regional Rheumatology Symposium.
An 'on safari' report was intended, but my laptop was attacked by Trojan Horse and worm viruses, after picking them up from the generic computer we used for the workshop. Fortunately the IT expert at my hotel was able to clean the flash drive and I just shut the computer down. Now all is clean and healthy again.

The big 'take home ' message of the workshop was the need for team work in assessing and managing the effects of arthritis in any form.
The interaction between the physiotherapist, occupational therapist, rheumatology specialist nurse, podiatrist and rheumatologist; plus all the other health professionals, was highlighted by the team that came to Nairobi from Glasgow.
Their big message was that the centre of focus must always remain the patient. They also showed how their individual professions have developed extended scopes of practice to enable a massive reduction in waiting lists in Scotland, due to the screening interventions that they are allowed to do.
Despite the apparent skills shortage in Kenya – there is only one rheumatologist in the whole country – there are many skilled and enthusiastic allied health professionals plus other doctors such as GP's, physicians and orthopaedic surgeons interested in getting involved with managing arthritis. I met many of them during the week.
Delegates at the Regional Rheumatology Symposium
Additional talks were on 'Arthritis, feet and podiatry' and 'Footwear for problem feet'. In the practical sessions, delegates were shown how to make a basic insole and use padding onto the foot and into the shoe. More on this another time.
Oh yes. Traffic. I will never complain about Johannesburg traffic jams or driving again. The rush hours are gridlock in extremis; unbelievable.
Thank you AFLAR for the invitation and Roche Pharmaceuticals for the financial assistance.
