猪手，又叫猪脚、猪蹄。其分前后两种，前蹄肉多骨少，呈直形，后蹄肉少骨稍多，呈弯形。中医认为猪蹄性平，味甘咸，是一种类似熊掌的美味菜肴及治病“良药”。一般来说猪手就是指猪的前蹄子，猪蹄是指猪的后蹄子。
A ham hock (or hough) or pork knuckle is the joint between the tibia/fibula and the metatarsals of the foot of a pork, where the foot was attached to the hog's leg. It is the portion of the leg that is neither part of the ham proper nor the ankle or foot (trotter), but rather the extreme shank end of the leg bone.
