I clicked the site you provided and I understand your problem!
I, myself has a problem, not with my little finger, but with my Index finger. The same finger we will use to barre chords. Now, try this solution!
Use a CAPO, so instead of using your Index finger to barre the chords, you can use that Index finger to fret and free your little finger that you're having difficult using or cannot use. Good enough?
The only problem in using CAPO is if you want to navigate from fret to fret, meaning up and down the fretboard using the barre chords. You will keep on placing and removing the CAPO, from one fret to another. But, at least, you can play and solve your problem with your little finger, right?
Same suggestion with all you guys, like me, who have problem with a finger!
Use the CAPO so you can use a finger to substitute the finger that you are having difficulty using or cannot use.
Hope this suggestion will help!!!
Keep on playing!!!
