I had a compound fracture of the right hand a few years back (idiotic, very cheap, high speed, overhead metal ceiling fan in a public place....the same year, a father accidentally scalped his two year old son lifting him up.) I compared the injury to the kind endured in a sword battle of old.

Had a wonderful, national specialist of a doctor; a doctor that surgeons go to when they break a hand. No set to the bone - the body has a marvelous capacity to heal and redistribute calcium of the bones when the muscles are actively in use.

Have patience - lots and lots of patience.

It will probably take years for it to become "normal." I had almost given up hope it ever would. I had hoped I might also get an extra key into the note span - nope.

Loved the hot wax "warm-up" of occupational therapy. (My favorite childhood piano teacher used to use the hot paraffin to get a few hours relief from arthritis)

The best therapy is to eventually forget it. Carrying things (bags) seems to stretch it out. Pull weeds. Knead bread. Do origami. Button buttons. And, of course, play - no matter how uncoordinated.

Counting back - I would guess it took the proverbial seven years to regain 98%. Just work through the discomfort and awkward control of the first three years. Practice the more difficult finger patterns of your good hand that you "never had patience for."

GOOD LUCK and Best Wishes,

Sincerely,
