Thumbs are defined as unacceptable if IP joint deviation exceeds 15 degrees, MCP joint deviation exceeds 30 degrees, and thumb size is inappropriate based on the examiner's assessment. Also, thumb size one-third greater or less than the contralateral thumb is defined as unacceptable. [7]
A broken finger or finger fracture is a common type of bone fracture, affecting a finger. [1] Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger. [2] Although most finger fractures are easy to treat, failing to deal with a fracture appropriately may result in long-term pain and disability.
Hypermobile metacarpo-phalangeal joints Hyperextension of the thumb Hyperextension of the hand. Hypermobility syndrome is generally considered to comprise hypermobility together with other symptoms, such as myalgia and arthralgia. It is relatively common among children and affects more females than males. Current thinking suggests four ...
Brachydactyly type D, also known as short thumb, [3][1] stub thumb, [5][6] or clubbed thumb, [5][6] is a genetic trait clinically recognised by a thumb being relatively short and round with an accompanying wider nail bed. The distal phalanx of affected thumbs is approximately two-thirds the length of full-length thumbs.
Bennett's fracture. The Bennett fracture is an oblique intraarticular metacarpal fracture dislocation, caused by an axial force directed against the partially flexed metacarpal. This type of compression along the metacarpal bone is often sustained when a person punches a hard object, such as the skull or tibia of an opponent, or a wall.
Syndactyly. Partial simple syndactyly in the second and third toes. Specialty. Medical genetics. Syndactyly is a condition wherein two or more digits are fused together. It occurs normally in some mammals, [1] but is an unusual condition in humans. The term is from Ancient Greek σύν (syn) 'together' and δάκτυλος (daktulos) 'finger'.

When an object, such as an adult finger, is placed in an infant's palm, the infant's fingers reflexively grasp the object. [1] Placement of the object triggers a spinal reflex, resulting from stimulation of tendons in ...
Symbrachydactyly is a congenital abnormality, characterized by limb anomalies consisting of brachydactyly, cutaneous syndactyly and global hypoplasia of the hand or foot. [1] In many cases, bones will be missing from the fingers and some fingers or toes may be missing altogether. The ends of the hand may have "nubbins"—small stumps of soft ...
