Permanent flexion of the proximal interphalangeal joints, although symptoms may vary in person; some people have very tight flexed fingers and other people have flexed fingers that straighten when pressed on [1]
Complications
People with severe camptodactyly may have difficulty holding objects
Usual onset
There are congenital forms, adolescent-onset forms and acquired forms [2]
Duration
Life-long
Treatment
Splinting, surgery, etc.
Frequency
1% of the world population [3][4][5]
Camptodactyly is a medical condition that causes one or more fingers or toes to be permanently bent. It involves fixed flexion deformity of the proximal interphalangeal joints.
Camptodactyly can be caused by a genetic disorder. In that case, it is an autosomal dominant trait that is known for its incomplete genetic expressivity. This means that when a person has the genes for it, the condition may appear in both hands, one, or neither. A linkage scan proposed that the chromosomal locus of camptodactyly was 3q11.2-q13.12.[6]
