Thumb: The first digit on the radial side of the hand which in humans lies opposite the other four.Carpometacarpal Joints: The articulations between the CARPAL BONES and the METACARPAL BONES.Metacarpophalangeal Joint: The articulation between a metacarpal bone and a phalanx.Fingers: Four or five slender jointed digits in humans and primates, attached to each HAND.Trigger Finger Disorder: A painful disability in the hand affecting the finger or thumb. It is caused by mechanical impingement of the digital flexor tendons as they pass through a narrowed retinacular pulley at the level of the metacarpal head. Thickening of the sheath and fibrocartilaginous metaplasia can occur, and nodules can form. (From Green's Operative Hand Surgery, 5th ed, p2137-58).Finger Joint: The articulation between the head of one phalanx and the base of the one distal to it, in each finger.Hand Strength: Force exerted when gripping or grasping.Hand Deformities, Congenital: Alterations or deviations from normal shape or size which result in a disfigurement of the hand occurring at or before birth.Trapezium Bone: A carpal bone adjacent to the TRAPEZOID BONE.Finger Injuries: General or unspecified injuries involving the fingers.Polydactyly: A congenital anomaly of the hand or foot, marked by the presence of supernumerary digits.Rheumatic Nodule: A small round or oval, mostly subcutaneous nodule made up chiefly of a mass of Aschoff bodies and seen in cases of rheumatic fever. It is differentiated from the RHEUMATOID NODULE which appears in rheumatoid arthritis, most frequently over bony prominences. (From Dorland, 27th ed)Toes: Any one of five terminal digits of the vertebrate FOOT.Hand: The distal part of the arm beyond the wrist in humans and primates, that includes the palm, fingers, and thumb.Splints: Rigid or flexible appliances used to maintain in position a displaced or movable part or to keep in place and protect an injured part. (Dorland, 28th ed)Metacarpal Bones: The five cylindrical bones of the METACARPUS, articulating with the CARPAL BONES proximally and the PHALANGES OF FINGERS distally.Amputation, Traumatic: Loss of a limb or other bodily appendage by accidental injury.Metacarpus: The region of the HAND between the WRIST and the FINGERS.Neoprene: An oil-resistant synthetic rubber made by the polymerization of chloroprene.Movement: The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.Hand Deformities, Acquired: Deformities of the hand, or a part of the hand, acquired after birth as the result of injury or disease.
