Broken finger needs help

[rayrodo]

X-rays were taken when the finger was broken. a ball hit me on the tip of the finger and pushed it so hard in towards my hand , bang on, that i split the finger bone as it joined on the the knuckle part of the hand. The finger has been strapped for the last 5 weeks to my ring finger to brace it and support it. as of Yesterday i have decided to leave it unstrapped in order to try and get more moement in my finger and to get rid of the stiffness. The finger closes most of the way and almost opens straight but still tends to be a little bent when extened to max.

I wanted to know if there was any stretching exercise or bending or straighting excercise to help the finger become more mobile as well a become less stiff.

Any advice on the matter will be greatly apprciated.
