Clinodactyly (from Ancient Greek ??????? klÃÆ'nein which means "bending" and "latin" title = "Ancient Greek text"> dÃÆ'¡ktulos < meaning "digits") is a medical term that describes the curvature of a digit (finger or toe) in the palm of the hand, most often the fifth finger ("pinkie") toward the adjacent fourth finger ("ring finger").

This is a fairly common isolated anomaly that is often overlooked, but also occurs in combination with other disorders of certain genetic syndromes.

Genetics

Clinodactyly is an autosomal dominant trait that has variable expressiveness and incomplete penetration.

Klinodactyly can pass inheritance and present either as an isolated anomaly or a component manifestation of the genetic syndrome. Many syndromes are associated with clinodactyly, including:

• Down Syndrome
• Turner's Syndrome
• Aarskog Syndrome
• Carpenter Syndrome
• Seckel's Syndrome
• Cornelia de Lange's Syndrome
• 1 orofaciodigital syndrome
• 13q removal syndrome
• XXYY syndrome
• Silver-Russell Syndrome
• Andersen-Tawil's Syndrome

When identified before birth, for example during ultrasonography midwifery, may be an indication for intrauterine sampling for fetal chromosome analysis as it is statistically correlated with an increased risk of chromosomal aberrations in the fetus.

Pathophysiology

Because of the developmental arrest there is a normal alignment of the joint surface in one of the interphalangeal joints causing angulation in the palm of the hand. Fingers may be slightly bent or have a very prominent bend.

Diagnosis

There is no consensus about the degree of angulation that justifies the diagnosis, the slope between 15 Â ° and 30 Â ° is typical. An audible-like term, camptodactyly, is the flexural flexibility fixed from the digits.

Management

Treatment is only necessary if the level of curvature is sufficient to cause disability or if it causes emotional distress. Splinting does not routinely improve deformity. Surgical treatment closes the sliced ​​osteotomy, opens the wedge osteotomy, and reversed osteotomy. Radiography of the radius is useful in planning surgical procedures. Severe klinodactyly may require soft-tissue changes in digits such as skin discharge, extensor tendon relocation, and increased collateral ligaments.

Epidemiology

The degree of small curvature is common. Incident reports vary between 1% and 19.5%.
