Abstract:
We report the case of a man with bilateral monodactyly whose sole remaining (third) finger on each hand is sensitive and mobile, and whose wrist motor control is normal. Opposed to the palm, the finger provides sufficient clamp function to manipulate medium-sized objects, while bi-manual grip is used for either very thin or voluminous items. Some gestures, such as using a crank, are achieved by simple palm pressure. His foot deformations have no functional consequences. His excellent driving skills suggested that he would be capable of learning to fly an airplane after two years of training with a private instructor, the Inspector of Civil Aviation and Medical Council of the Civil Aeronautic Board gave him the all-clear. Without the need for special equipment, this man is able to write, to drive a car with a manual gearbox, and now to fly passenger-carrying single-engine planes throughout the world.

Muscles of the Forearm that Move the Hand and Fingers
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
Changes in the Appendicular Skeleton with Age
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
