Chilblains

Chilblains area common problem in some countries and unheard of in others. They tend to commonly occur in colder climates.

Once they occur, it is important to keep the foot warm (link to advice) and prevent it from happening again. There is not a lot of research done on them despite how common they are (link to the research). They are more common in females, so that suggest hormonal issues, but the do occur in males. Lots of questions gets asked in forums and often the answers for a “cure” are just not there, so a lot more research is needed to get to the bottom of this small, but annoying problem.

What is a plantar plate tear?

The plantar plate is a strong ligament under the joints at the base of the toe in the ball of the foot. It is reasonably common to strain that ligament or have a small partial tear in it.

Typically, this starts as a slight ache under the ball of the foot that can be quite painful on palpation. The toe of the affected joint also tends to lift up off the ground.

Many questions get asked in forums and message boards on how to treat this, especially if it can heal on its own. It can’t. Treatment is almost always needed. Most the best way to treat it, is with strapping:

If that conservative approach is not helpful, there surgery is often needed.

Do bunion correctors work?

Bunion correctors are splints that are supposed to hold the big toe in a correct position and fix bunions. Lots of questions get asked online if they work (see here and here for examples). There does seem to be a moderate consensus that they may help a small amount.

Bunion correctors probably do not fix bunions, but will improve the angle of the big toe a small amount. Only surgery will make it go away.

There is a lot of marketing hype around the selling of these. See this: Bunion corrector gullibility. Don’t fall for it. At best, they will improve the ankle of teh big toe by a small amount and may be helpful with the pain in the joint. That may be a good thing.

Archies Arch Support Thongs

Firstly, in Australia they call flip flops “thongs”! The Archies Thongs are are proving very popular in Australia for those who do and do not need foot orthotic support and want to wear a flip flop type of footwear to to the warmer climates. The flip flop has a built in arch support that is both effective and comfortable.

A number of podiatry clinics are stocking them and you can get them online.

They were design by a phsyiotherapist in Melbourne, Australia. The amount of arch support in them is comparable to a typical ‘over-the-counter’ premade foot support, which is why they are so popular.

Gowers Sign

Gower’s sign is a neurological symptom that was first described in how a child with the sign gets up from the floor:
(i) the child initially adopts a prone position on all fours before they attempt to stand
(ii) the child uses their hand to ‘walk up their legs’

Gower’s sign occurs when there is a weakness of the core or pelvic muscles. The most common reason for the sign is Duchenne’s muscular dystrophy.

The Ipswich Touch Test

The loss of sensation in the foot in those with diabetes is a significant problem. There are many different ways that a podiatrist can assess that, ranging from the use of sophisticated tools to simple tests. The recently validated Ipswich Touch Test is one of the simplest:

The Ipswich Touch Test is done by lightly touching the tip of the 5th, 3rd and 1st toes of both feet and seeing if they can feel the touch. Its that simple – it has been shown to be valid and have good sensitivity and specificity for sensory loss. It is not too difficult to imagine what could happen to the foot if they can not feel it being touched. Check these resources on it.

Ankylosing Spondylitis and the Foot

Ankylosing spondylitis is a problem that mostly affects the spine with a form of arthritis. It can also affect other points and some other organs. The problem in the spine affects mobility and creates a progressive deformity that will need a lot of physical therapy to manage.

It affects the foot in three ways:
1. The arthritis like symptoms can affect the joints in the foot
2. Pain in the heel similar to plantar fasciitis is common
3. Due to the affect on the spine, the ability to reach the feet and do self-care is difficult.

What is an Abductory Twist?

An abductory twist is an observation made during gait in which there is a sudden abduction of the heel just as the heel comes off the ground. Some call this a medial heel whip.

There are two schools of thought as to what causes an abductory twist:

1) The one described in the video is the most commonly believed reason and is due to a foot that is overpronating as the leg is externally rotating. As soon as load comes of the heel, this causes the foot to suddenly abduct. The pathomechanics of this is discussed in detail here. Those who subscribe to this reason tend to call it an abduct0ry twist.

2) The other believed cause is that there is a weakness of the hip abductors. Those who subscribe to this view tend to call it a medial heel whip.

Trench Foot

Trench foot was a cold injury that was really common in the trenches during war time. Th soldiers were subjected to cold and damp as well as unsanitary conditions. This no freezing injury affected a lot of soldiers and still is an issue in today’s armies.

It is just not a problem now for the army, but trench foot can occur in extreme sports in cold environments and in those with occupational risk such as cold store workers. It is more appropriately called a non-freezing cold injury. Frostbite is a freezing cold injury and the cold directly damages the tissues. In a non-freezing cold injury the tissue damage is more related to changes in the circulation.
