Specialty. Medical genetics. Clinodactyly is a medical term describing the curvature of a digit (a finger or toe) in the plane of the palm, most commonly the fifth finger (the "little finger") towards the adjacent fourth finger (the "ring finger"). [citation needed] It is a fairly common isolated anomaly which often goes unnoticed, but also ...
Brachymetatarsia is a rare malformation that causes one or more toes to be abnormally short. The condition is characterized by a metatarsal arch shortness of more than 5 mm. The condition is more common in females, and the incidence reported in the literature ranges from 0.02% to 0.05%. Brachymetatarsia appears to be the result of epiphyseal ...

Saethre–Chotzen syndrome (SCS), also known as acrocephalosyndactyly type III, is a rare congenital disorder associated with craniosynostosis (premature closure of one or more of the sutures between the bones of the skull). This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face.
Camptodactyly is a medical condition that causes one or more digits (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 ...

A hammer toe, hammertoe or contracted toe is a deformity of the muscles and ligaments of the proximal interphalangeal joint of the second, third, fourth, or fifth toe, bending it into a shape resembling a hammer. In the early stage, a flexible hammertoe is movable at the joints; a rigid hammertoe joint cannot be moved and usually ...

It is classified as a branchial arch syndrome, affecting the first branchial (or pharyngeal) arch, the precursor of the maxilla and mandible. Disturbances in the development of the branchial arches in fetal ...
