Short first ray

Hi everyone!

I am Kimberly.

I have got a query on short first met. I have seen a patient who has short first met and he is having some pain in second MPJ.

May I know if first ray cut out will allow the short first ray to plantarflex to allow windlass mechanism?

Will short first ray be dorsiflexed when patient weight bears? How does short first ray functions?

Thank you!!!

Cheers,
Kimberly

 

Hi Kimberly :welcome: to Podiatry Arena

There are many threads with 1st ray, windlass if you go into the biomechanics forum advance search and put in 1st ray you will find lots of info for you.

But here is some quick info. A short 1st ray will lead to increase Ground reaction force ( GRF) to the 2nd ray/2nd metatarsal. You see it alot with people post Hallux Valgus surg which shortens the 1st ray. They maybe happy with the surg result but now have pain in the 2nd metatarsal head. The results of the increased GRF will result in increased bending moments of the 2nd met. So with your treatment you may want to look at reducing the GRF under the 2nd met.

An orthotic with a metatarsal dome will reduce the GRF under the 2nd, a device with a web ppt with cut out for the 2nd metatarsal head will also. There are more ways you can decide which way is best.

Hope that the info helps.

 

Many thanks for your reply Michael!!!
