Carbon Plate for Hallux Rigidus

I have been using these a bit lately. You know, you have a run of something in the clinic and then don’t see it for months. at the moment its using the carbon fibre plates for hallux rigidus.

I do have a bit of dilemma using them. Yes, they do work really well for hallux rigidus and pretty much every one that I have used them on lately has had a good outcome and that is supported by the evidence. However, I also know that they are going to interfere with the windlass mechanism and affect thing like Bojsen-Mollor high gear, low gear concept. We just do not know the long term impact of interfering with that. However, on the other hand, neither of those mechanisms is working too well becasue of the hallux rigidus. I guess this is just one of those occasions where you have to weigh up the options and make the compromise to get a good clinical outcome.

Personally, I prefer the ones that are more of a Mortons extension as that still does allow a somewhat more normal function of the lessor metatarsophaplangeal joints, so the compromises are not as much is the carbon plate covered the whole forefoot area.


PodChatLive is a weekly video live stream that I co-host with Ian Griffiths on Facebook. After the live stream, its available on YouTube and our website. The audio version is also available as a podcast.

It all started when I was in the UK and visited with Ian and his family for dinner. After dinner, Ian set his phone and we went live on Facebook to have a discussion about whatever came up. When I returned we repeated it remotely. The following week we had on a guest (Chris Bishop) and it went from there. We now have a different guest or group of guests on each week and it is free to watch and will always remain so.

Why? We like the feedback, we like the positive comments. We do not charge for it and make no money from it, so all get from it is the positive reception that it gets.

Supination Resistance

Supination Resistance is another one of those topics that I find myself writing about a lot (eg here and here)and something I have been banging on about in my Clinical Biomechanics Boot Camps for years.That is how important I think that the concept is.

The concept has its origins in the concept of overpronation probably not be all that it is cranked up to be, so rather than focus on “overpronation” perhaps he focus should be on the forces that are associated with the function of the foot and pronation. It just makes a lot more intuitive sense o be focusing on the forces rather than the motions. It is the forces that actually do the damage to the tissues rather than motion. Motion is not painful.

I have certainly done a lot of research on it and unfortunately never quite got to publishing it. I did summarize most of the research done in this post.

This video from PodChatLive on the supination resistance text brought together all the researchers on this topic.

Peroneal Tendonitis

You see peroneal tendinitis come up often as questions in forums, so a while back I wrote a lengthy post on it that a lot of people refer to, which is great as I really wanted to get the information out on this.

It is a condition that I often see from comments in forums that is frequently mismanaged. I do spend a lot of time on it at my Clinical Biomechanics Boot Camp course and like to tell the story about how I used to hate seeing it as my success rate used to be close to 100% failure; now its close to 100% success. The change was that dramatic once i realized what was going on with it; hence my reason for writing the blog post that I referred to above.

HINT: it almost always occurs in those with low supination resistance.
