Camptodactyly

Camptodactyly is a clinical or imaging descriptive term where there is a flexion contracture (usually congenital) classically at the proximal interphalangeal joint.

The age of presentation can vary from being detected in utero in an antenatal scan or as an obvious deformity after birth or in childhood.

There is often thought to be an abnormal insertion of the lumbrical or flexor digitorum tendons into the hand.

It can occur sporadically or with an autosomal dominant inheritance.

While it can occur in isolation, there are numerous associations with the presence of camptodactyly (especially if detected in obstetric imaging):

The involved joint is flexed and often can't be straightened. The phalangeal head may be small and if the flexion contracture is severe enough, the phalangeal head may articulating with and erode the dorsal cortex of the neck of the proximal phalanx.

  • non operative: stretching or splinting
  • operative: lumbrical insertion excision +/- FDS release or transfer
