Adrian, I don't recall what your hand looked like before and how long your contracture had prevailed until you had surgery. Both determined the outcome to some extent.

On your picture also your MCP (base joint) is bent but I guess that's just a normal bending and you can fully straighten it?

If you keep wearing your night splint for another 3-6 months there is a slight chance that your PIP might still straighten a little. At least someone reported that in our German forum. I wouldn't wear the night splint for too long during the day, your fingers need to move to keep the joints flexible. Eventually, after your wounds healed fully, you might also try massaging your finger and your PIP maybe a little straighter.

Obviously also a part of your aponeurosis in the palm was removed and you will develop scarring there. I myself had a similar surgery (my hand is on the bottom of http://www.dupuytren-online.info/dupuytren_surgery.html with the cuts indicated). I experienced some tightness afterwards and have to admit that that never went away. I still have it, 9 years after surgery, but got used to it and it doesn't bother me anymore. My hand never became what it used to be but it is fully functional.

Flexibility is very important. During the day you should be flexing your hand in both directions, making a fist and then flexing to a flat hand. Each day you should be trying to increase the range of flex. I only went to PT twice and then the rest was done on my own. My surgeon agreed that if a person was diligent, PT was not necessary. More importantly the individual PT should be done throughout the day.
