Thanks!

Finding nerve entrapments can be tricky, Conduction studies can even have results that aren't terribly alarming. My damaged calcaneal branch showed 40% reduction and the physiatrist was not too worried because this branch doesn't always read well. The clincher was when the plastic surgeon peripheral nerve specialist did a "scratch collapse test" that was positive. These are more commonly done for carpal tunnel but it was done at my ankle. Shows the exact place of the lesion or compression. I saw two different surgeons before deciding on my procedure, one in Houston one in Dallas, both did a fellowship at Washington University with Dr. Susan Mackinnon who is a nerve guru, she uses this test all the time.

There are some videos of the test. There are also some fascinating articles on CRPS resulting from nerve compression, one seemingly hopeless case Mackinnon operated on with great results. I will dig up the links and post them.
