All are true of Dupuytren's contracture except -
Usually 4th finger is involved
Bilateral disease is rare
Surgical release is useful
May be associated with Pyronie disease
Often both hands are affected (Bilateral disease), one more than the other.
The earliest sign is a small thickened nodule in the mid-palm opposite the base of ring finger.
Gradually this extends distally to involve the ring or little finger.
There is a rare, curious association with fibrosis of the corpus Cavernosum.
