This could be a number of things, the calf could have a pinched nerve, could have broken hips (result of mother accidentally stepping on it), the best way to discover what the problem is, call your veterinarian, they will be able to view the calf and diagnose the problem.
I hope that this is a help.
On its rear legs on the equivalent of what would be a knee on a human.
First, you have to get her in a head-gate, if she's a bit nervous of you poking around her rear. Then reach inside the birth canal to see if the calf's coming normally. If it's not, you will have to correct the calf yourself or phone the vet to come out and help you. Get the calving chains or calf puller on the calf and start pulling. Pull out and down, and pull when the cow strains. Once the calf is out, get it breathing by clearing the air-way and tickling its nose or ear with a clean piece of straw. Once and if the calf starts breathing and shaking its head, move it to a small pen where you can let the cow in with her new calf. Keep them there for a couple hours or until the calf has been up and suckling at his mother's udder. If you cannot pull the calf out without causing injury to the cow or calf, get the vet out to do a C-section on the cow.
It really depends on the animal. Some animals' feet are simply called feet. However, some of them have specific names. For some, like the dog, the feet are called paws. For some, like the cow, the feet are called hooves.
This is likely a pig being restrained for field castration, but this method is not often used for humane reasons.
Long-horned grasshoppers and crickets have "ears" on their legs. Short-horned grashoppers (the kind seen just about everywhere) are often said to have ears on their legs, but their hearing organ is actually located on the abdomen just behind the rear legs where the legs join the body.
Between your legs at the rear.
When a dog runs away from something in fear (usually after a fight), it will tuck its tail between its rear legs so its tail can't get bitten off. This is the origin of the phrase, so if someone runs away "with their tail between their legs", then they just lost an argument and are backing away.
Strong rear legs.
Seals do not have legs they have 2 front flippers and a rear tail.
There are a great variety of Dragons. Some have six legs but in the majority the second pair has evolved into a pair of wings. Some Dragons have lost the last pair of legs and have only wings and front legs. The Chinese Dragon has only four legs having lost the mid-pair altogether. Some have lost all their legs: Knuckers and Hydra. Then there are rare weird things that are deemed to belong to the same class as Dragons that have odder physiques. One such is the Vlariak River Dolphin. This blind bottom dweller has one rear leg with a webbed fin-like foot that it uses as a rudder. And some Dragons have four legs and a pair of wings. [European Dragon, etc.]
