Dogs, like other canids, normally have four claws on their rear paws; a fifth is often called a dewclaw and is especially found in certain dog breeds, [80] including the Norwegian Lundehund and Great Pyrenees. A number of mutations of the LMBR1 gene, in dogs, humans, and mice, can cause polydactyly. [80]

The severity of the damage caused by dogs ranges from scratches to loss of limbs. Attacks by several dogs and by certain types of dogs are described as particularly dangerous. The researchers came to the conclusion that certain types of dogs cause particularly serious injuries due to their way of biting, holding and shaking the victim.
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.
De Quervain syndrome is diagnosed clinically based on patient history and physical examination, though diagnostic imaging may be used to rule out fracture, arthritis, or other causes. The modified Eichoff maneuver , commonly referred to as the Finkelstein test , is a physical exam maneuver used to diagnose de Quervain syndrome. [ 2 ]
