A literature review of congenital digiti quinti varus: clinical description and treatment.

Congenital digiti quinti varus is a deformity in which the fifth toe overlaps the base of the fourth; it consists of three main components: adduction, dorsiflexion, and external rotation. Treatment for this deformity may consist of conservative or surgical techniques, depending on the severity and/or age of the patient. The surgical techniques recommended by various authors may involve skin plasties, tenotomies and capsulotomies, tendon transfers and lengthenings, and bone resections.
