Camptodactyly of finger
Permanent flexion of the finger
HP:0100490
What it means
The distal interphalangeal joint and/or the proximal interphalangeal joint of the fingers cannot be extended to 180 degrees by either active or passive extension.
Note that some restrict the use of the term to inability to extend the proximal interphalangeal joint of the fifth finger. We do not restrict the term in this way. This term should not be used if the patient has Clenched hand. A similar effect can be created by radial angulation within the distal phalanx with thickening of the epiphysis, which is called Kirner deformity or dystelephalangy. The affected digits should be specified.

The range is how often this sign appears among people diagnosed with each disease — it is not a probability of having any of them. Many of these signs also occur in common, non-rare conditions. A sign on this page is a conversation to have with a clinician, not a conclusion.
