Wendy, can you imagine the smell of a bath full of acetic acid..:)) Though I like pickles, it's still too much for me. And here --> https://www.researchgate.net/publication/305317105_A_Review_on_Ultrasound_Parameters_and_Methods_of_Application_in_Transdermal_Drug_Delivery is a review of the US parameters for transdermal drug delivery, which I find interesting. Anyway, some updates about the iontophoresis - I try it on two patients. The first is 8 months after nasty conquasation of the fingers of the hand. 3rd 4th and 5th proximal phalanges had comminuted fractures, reduced with ORIF, but probable because of the extensive soft tissue trauma there is a lot of internal scarring and the fingers are extremely stiff. With two weeks of acetic acid iontophoresis, together with long periods of splinting there is qute big increase of the passive ROM. Since the fracture was in the zone 2 of the flexor tendons and there was also a big cut on the palmar skin, we beleive that for active motion this patient will need extensive tenolysis. Will see. The other patient had some small bone spur in the PIP joint of the 5th finger, after a trivial sprain 2 and a half months ago. His improvement is that the feeling of compression in the joint, while flexing dissapeared and he started to feel the restriction of the sticked extensor aparatus on the dorsal side of the finger. The ROM also increased. After some more time we'll check for the bone spur with US sonography. Hopefully he will be good without surgery. That's it for now. If anyone is interested I will report what is happening after some more time. Happy new year!
