Ball of Foot Pain/Metatarsalgia/Calluses/IPKs
This pleasant, 82-year-old lady came to me complaining of horrible pain under her second and third balls/knuckles/MTPJ of her her foot.
Her foot presented toes that looked like claws, with advanced calluses on the bottom surface at balls/knuckles 2 & 3 that are referred to as IPKs (Intractable Plantar Keratosis)(pictured). She came to me with my competitor’s orthotic for an opinion. This orthotic she brought had no accommodation for her calluses other than a metatarsal pad. This is a bump on the top surface of the orthotic that is believed to remove pressure off of the knuckles/calluses. It does this two ways. One, by attempting to straighten the claw-like posture of the toes by adding an upward pressure, thereby stopping the calluses from continuing to occur. Two, the upward pressure “unweights” the calluses when the foot is flat on the ground.*
Because her chief complaint was the obvious calluses, I had asked her if the previous practitioner had noticed them and if that was her chief complaint when she saw him. She said yes but that her current orthotic offered no relief. She said that he had told her the metatarsal pad would have taken care of the calluses. She noted that the calluses had done nothing but get worse over time. Because the orthotic was made very well, I did not see the reason to charge the woman $425 to be able to help her. As it was she paid over $700 for orthotics that did not help her enough.
What I did was place the orthotic over her foot, and mark exactly where her calluses lined up on the bottom of her existing orthotic. Then, taking the device into my laboratory, I used my industrial Dremel to grind out the bottom material, as well as some of the shell, creating a very deep platform for each of her respective calluses.
The difference for the patient was night and day.
*Why didn’t the metatarsal pad work? If you Google search DIY cures for metatarsalgia, clawed toes or calluses, you’ll see the call for metatarsal pad. Whereas with this patient, her calluses only became worse (unbearable even). How come?
The answer is this, her clawed toes were rigid and the upward force from the pad did nothing to straighten the toes (if anything it even added more pressure). Also, because of metatarsal pad is located immediately behind the balls/knuckles of the foot, when the heel leaves the ground (when the calluses are most vulnerable) the pad is nowhere. For specific pressure underneath balls of the foot, the best way to relieve the pressure is to create a depression(s) underneath the device.
Instead of forcing this woman to spend $425 on a pair of new orthotics (which any practitioner would have done), she was charged $100 for her adjustment.
