Is a trigger finger and swans neck deformity part of Dupuytren’s contracture?
Dear Dr. Herazy,
I have Dupuytrens and swans neck and trigger thumb. Yes, I am Norwegian.
My question is trigger thumb and swans neck a part of Dupuytren’s contracture?
There are many degrees of involvement of the fingers when a person has Dupuytren’s contracture; some are worse and more involved than others.
A “trigger finger” occurs when a finger tendon stick or is caught in the tendon sheath due to sheath swelling or dryness. Depending on the number of fingers affected, location and degree of involvement it is possible to have a trigger phenomenon of one or more fingers. This is fairly common to happen in many cases of DC. See Trigger finger and Dupuytren’s contracture.
A “swan neck” deformity is a less common occurrence in Dupuytrens. This kind of finger deformity occurs when the cord pulls the involved finger in a state of hyperextension of the PIP joint, flexion of the DIP joint, and even sometimes an additional flexion of the metacarpophalangeal joint. Sorry to get technical with you in this explanation but I know of no other way to explain it. TRH
