My husband had this surgery approx. 6 years ago. It was more involved than we anticipated, but his doctor we believe did a great job, and gave really good advice. He has not had any return signs of the Dupuytren.
That said, he did all his hand therapy appointments. The doctor also said that he needed to do the daily hand exercises no matter how much it hurt. I was like a drill sargeant when it came to doing his hand exercises and we both agree that went a long way to making for a good recovery result.
Everyone is different and everyone heals differently,,,,,listen carefully to your doctor especially when it comes to what to do after the surgery. Best of luck to your both,
