I had z plastic done one time . The procedure seemed to activate the contracture . In less than a month after surgery my pinky finger began to curl up worse than original contracture before surgery. 4 months later 3rd and 4th fingers begin to contract. By 6 months three fingers had contracted to a fist. All while therapy and splints were used.

In my case the surgery caused the nodes in two additional cords to contract two additional fingers. Originally only had one cord to pinky effected.
My surgeon would not try surgery again, instead referred me to another hand surgeon for xiaflex injections. This procedure is painful but worked and straightened out all the cords in three fingers with several small injections in the palm area. That was 9 years ago. All fingers still ok.
However, over the past few years since xiaflex injections it’s important to take care to not do things to aggravate the palm,ie.vibrations and from pressure holding things. Wearing foxglove-a type of glove splint for Dupuytren’s at nite helps keep the contraction at bay.

Surgery caused thick scar tissue build up in my palm. Also in my case activated DC in two additional fingers along with the pinky.

Xiaflex eliminated all the thick scar tissue on my palm from surgery and the nodes on three cords with no recurrence of DC in 9 years.

Scar tissue and nodes on the cords are made up of collagen tissue which xiaflex is designed to dissolve. Within a month my hand was useful again .
