Hi there I am a new user to this great forum and have been reading interesting threads on casting and orthotic manufacture, mainly posting v's skives etc. I was wondering if anyone has any links to papers, or information for the blake inverted procedure? I am sure it is a simple technique and I understand the concept but just don't really know how to use - at the moment I use medial heel skives but don't invert the cast as Kevin Kirby suggests.
Would appreciate some feedback

cheers

There is a chapter in Valmassy on this. http://www.amazon.com/Clinical-Biome...46895&sr= 8-1

many thanks Simon I searched the internet and couldn't find anything, I have the valmassey book but didn't think to look there, Doh!!!

I used Blakes original publications going back to 1978? JAPMA I think...I'm sure Craig could tell you off the top of his head...there were two or three that gave me enough to start making them.....one written with a female co-author?.....dredging the bottom of a foggy memory here

Marc:

Dr. Richard Blake did the CCPM Biomechanics Fellowship a few years before I did the Biomechanics Fellowship. I helped him make his inverted orthoses for him when he was first creating the technique (when I was a 3rd year podiatry student). The chapter in Valmassy's book is an excellent review Dr. Blake's technique. I also discuss the biomechanics of the Blake Inverted Orthosis in the chapter that Don Green and I did in DeValentine's book (Kirby KA, Green DR: Evaluation and Nonoperative Management of Pes Valgus, pp. 295-327, in DeValentine, S.(ed), Foot and Ankle Disorders in Children. Churchill-Livingstone, New York, 1992).

Here are the other Blake Inverted Orthosis Technique references for your reading pleasure:

Blake RL, Denton J: Functional foot orthoses for athletic injuries. JAPMA, 75:359, 1985.

Blake RL, Ferguson H: Foot orthosis for the severe flatfoot in sports. JAPMA, 81:549, 1991.

Blake RL: Inverted functional orthoses. JAPMA, 76:275-276, 1986.

Blake RL, Ferguson H: "The inverted orthotic technique: its role in clinical biomechanics.", pp. 465-497, in Valmassy, R.L.(editor), Clinical Biomechanics of the Lower Extremities, Mosby-Year Book, St. Louis, 1996.

Thats brilliant, thanks for your help!

hello,

reading Valmassy p 448 it says that a 25 degree inverted orthoses (Blake inverted) is standard practice, and that this orthotic can correct up to 5 degrees of rearfoot valgus-
1- can anyone tell me if an orthotic such as this is good for a child?
2 - does the plantar fascia not become irritated as a result of the contoured shape at the medial longitudinal arch; inversion, especially with very active children?
3 - does the altered coupling of the ankle/subtalar and knee cause any knee pain?

thanks

1.Sometimes
2.If the shape is right, no
3.Sometimes.
