Camptodactyly/Clynodactyly
Camptodactyly is the term that describes a flexion deformity of one of the fingers; the finger with this difference is bent and cannot be straightened. Camptodactyly can be caused by problems in the tendons the ligaments or the bones of the finger. This difference presents in approximately 1% of the population, the cause of this difference is not known but it can be associated with other congenital differences or syndromes this is why prompt assessment by a specialist is required.
An experienced hand surgeon must examine the hand of the child in order to initiate appropriate treatment. Usually camptodactyly can be managed without surgery, passive stretching exercises or finger splinting may correct the deformity. Some surgical procedures can be indicated by the hand specialist when the flexion contracture of the finger is larger than 30°. Surgical procedures depend on each case individually, but tendon excisions and transfers can be performed to correct this difference. Although correction can be obtained, the risk of residual flexion is always present.
Clinodactyly refers to the curving of the fifth (little) finger toward the fourth (ring) finger. This difference occurs because of a misshaped bone of the fifth finger. This minor difference can be found in a completely normal child, but it’s also a common finding in patients with Down and Klinefelter syndrome. This difference does not require any treatment, finger and hand function is normal.
