The arm of Velociraptor was formed by the humerus (upper arm bone), radius and ulna (forearm bones), and manus (hand). Velociraptor, like other dromaeosaurids, had a large manus with three elongated digits (fingers), which ended up in strongly curved unguals (claw bones) that were similar in construction and flexibility to the wing bones of ...
In 2009, Manning and colleagues undertook additional analysis dromaeosaur claw function, using a numerical modelling approach to generate a 3D finite element stress/ strain map of a Velociraptor hand claw. [44] They went on to quantitatively evaluate the mechanical behavior of dromaeosaur claws and their function.

They analyzed the bio-mechanics of how stresses and strains would be distributed along the claws and into the limbs, using X-ray imaging to create a three-dimensional contour map of a forelimb claw from Velociraptor. For comparison, they analyzed the construction of a claw from a modern predatory bird, the eagle owl. They found that, based on ...
It was also suggested that lighter dromaeosaurids such as Velociraptor and Deinonychus relied on their hand claws to handle prey and retain balance while kicking it; in contrast to this, the heavily built Utahraptor may have been able to deliver kicks without the risk of losing balance, freeing the hands and using them to dispatch prey.

Lastly, he restored the course of the fight with the Protoceratops powerslamming the Velociraptor, which used its raptorial sickle claws to damage the throat and belly regions and its hand claws to grasp the herbivore's head. Prior to their burial, the fight ended up on the ground with the Velociraptor lying on its back under the Protoceratops.

The fossil of a Velociraptor fighting a Protoceratops shows that the Velociraptor pierced the neck of its prey, possibly to impale the arteries or the vein. Velociraptor's wings were used for balance and agility, much like the wings of an African ostrich. Along with its claws, Velociraptor's teeth were useful weapons.
