The Potentailly Injurious Effects of Forefoot Varus Posting

Forefoot varus is very rare, but when it is present, the rearfoot has to pronate to bring the medial side of the forefoot down to the ground. The traditional approach to dealing with forefoot varus is to use a foot orthotic with a medial forefoot post to bring the ground up to the foot so the rearfoot does not have to pronate.

Relative Importance of STJ Motion

As far as I can see, Dr. Merton Root, used a brilliant approach, trying to correlate measurable structural differences with the presence of pathology. His discovery of Neutral position was certainly his greatest accomplishment. Some feel that Rootian biomechanics is dying. I do not. After my recent research at the Smithsonian, I have come to the conclusion that Merton Root actually did come up with the correct rotational position around the STJ axis.

Infants wearing shoes too early

Just wondering what your opinions are on what age infants should start wearing shoes?

Obviously in built up and litter ridden areas we cannot go barefoot and need some protection. But is the rise in 'baby fashion' damaging infants feet?

Extracorporeal Shock Wave Therapy

This treatment does not appear to have gained favour in the UK. I have spent the last year in the US, where the treatment often now preceeds surgical intervention.

I am interested to hear from any practitioners willing to share their experience of using ESWT in the treatment of heel pain/achilles tendon pathology.

Tibial nerve block to promote plantar diabetic ulcer healing

I have been considering lately the option of a tibial nerve block with 0.5% Bupivicaine for prolonged hyperaemia to accelerate healing. Has anyone had experience with serial injections for this and whether it made a difference to ulcer healing rates.

Leg Length differences

Although I have many strategies for determining whether an apparent lld/hip level difference is functional or structural, then (barring the blindingly obvious) I find this simple strategy works well.

Lateral arch on orthosis: do or don't?

If you go back to the locking mechanism decribed by bosjen moller in 1979, a lot is written on how it suppose to works:
"Prerequisite for this locking of the joint is that the calcanean process fits closely into its recess, and that the dorsal border of the
calcaneus overlaps the cuboid and stops the pronation of the forefoot. These conditions were not found in the flat variety of the cuboid, probably indicating a less effective locking mechanism in these joints. It could not be determined from the specimens whether such joints were associated with flat feet."



 

"Foot and Ankle Injection Techniques" provides the student and practising podiatrist with all they need to understand when, how and what to inject. To support the clinician and student, the text covers: changes in legislation; the full range of injectable drugs available to the practitioner; and, essential information on nerve physiology, drug action, equipment, patient selection, injection techniques and many other topics.
