Hamsters are small quick creatures. Unfortunately, their squirming can cause them to be dropped. If they fall from a height, it is all too easy for a bone to snap, most commonly a back leg. A broken bone, also known as a fracture, is a serious problem, and you must always put your pet's welfare first when deciding what is best. If your hamster has a fracture, you'll need to take him to the vet.

Responding to a Fracture

  1. You may be able to tell that your hamster is in pain. He might not be as active or won't want to move at all. Other signs that your hamster has a fracture include: [1]
    • Swelling
    • A crackling or popping sound (from the broken bone rubbing against itself)
    • The bone visibly sticking out of the open wound (which is rare)
  2. Once you suspect your hamster has a broken bone, you need to determine what type of a break he has. If it's an open fracture, the white of the bone will be visibly poking through the skin. If he has a closed fracture, the bones aren't visible and there's no skin wound. Instead, the broken bones remain sealed within the muscles of the leg. If your hamster has a closed fracture, you will notice: [2]
    • Dragging of the leg
    • The hamster avoids putting weight on the leg
    • A crunching sensation beneath your fingers when you gently feel the area

  3. If your hamster has a fracture, you must visit the vet. You won't be able to treat a break at home and without medical treatment, and if it is an open fracture, your hamster can get infected bone stumps, leading to general tissue infection, blood poisoning, and death. This is slow and painful for your hamster, so get immediate help.
    • If it is an open fracture, you should be prepared for the vet to suggest euthanasia, to prevent the hamster from suffering. If there's no medical option to treat the leg, euthanasia will save your pet from pain and suffering.
  4. If your hamster has an open fracture, the veterinarian may suggest that the best course of treatment is amputating the limb, or trying to fix the fracture. Both of these are high risk procedures that need to be done under strict sterile surgical conditions in order to avoid infection. Your hamster will need anesthesia to deal with the pain. Be aware that the procedure is high risk and there is a high likelihood of the hamster passing away.
    • Do not try to replace the bone ends under the skin without anesthesia, since this is incredibly painful for your hamster. It should only be done under trained medical supervision.
    • Do not give pain relief at home since the small size of the hamster makes it inevitable you will overdose the hamster. Too much pain relief is harmful and could cause gastric ulcers or death.

Managing Closed Fracture Treatment

  1. After taking your hamster to the veterinarian, take away the hamster wheel to prevent further damage to the leg. If he lives in a rotastak system with multiple levels and pipes to climb through, remove all of the connections, shelving, or ladders to keep him in one unit. You should also avoid putting him in his exercise ball while his leg is healing. In general, avoid handling him in case he struggles and moves awkwardly on the broken leg. [3]
    • By preventing the hamster from being too active, you will reduce the amount of weight he places on the leg. This lets the fractured ends start knitting together and repairing.
    • If the hamster is active and uses his wheel, he will disrupt the early scar tissue and delay or prevent healing from taking place.
  2. Feed a nutritious diet. Talk with the veterinarian about recommending a healthy diet that includes fresh fruits and vegetables. Consider offering them dried vegetables and other pellets so that they don't rot when your hamster tries to hoard them in a corner of his cage. You may also want to offer milk to drink, since the calcium can help heal bones. But, make sure the milk is fresh and replaced at least every two hours to avoid bacterial contamination. Don't feed your hamster too much, or it may grow overweight, which would put extra weight on its broken leg. [4]
    • Not all hamsters can digest milk, so if his pellets become soft or he develops diarrhea, stop offering milk immediately.
  3. Since hamsters are so small, it's impossible to bandage the fracture in any way that will help the healing process. It's more likely that a bandage would rub and cause skin sores, or distress your hamster. Your hamster would most likely chew off the bandage, possibly swallowing some of it. The pressure of a bandage on the fracture could also cause more pain. [5]
    • Keep in mind that while other animals, like cats or dogs, can have fractures supported in bandages, their bones are first aligned. The tiny size of a hamster makes this impossible to do.
  4. Typically, a fracture takes at least 4 weeks to heal, but some hamsters could take longer, up to 12 weeks. Once you've given him some time, watch for signs of healing, like walking on the leg, or no swelling over the fracture site. When you gently handle the leg, he won't react with pain and there shouldn't be any grating if the fracture has healed. If he reacts with pain, stop handling him immediately.
    • The clearest way to tell if healing is complete is to have your hamster x-rayed. But, this is expensive and you may need to anesthetize your hamster. [6]
    • If your hamster has healed, you can reintroduce his wheel or multiple levels of his cage. There is a chance that your hamster's leg may heal incorrectly. If it does, don't panic. Just monitor your hamster and it should be fine.

    Yes, hamsters can break bones. The bones in a hamster's leg are thinner than matchsticks and may break accidentally, such as if the hamster is dropped from a height.

      Article Summary X

      To treat your hamster’s broken leg, you’ll first need to confirm the type of break before deciding to treat it at home or go to the vet. If you see the bone sticking out through its skin, this is an open fracture. Open fractures must be treated by a vet, because they can lead to infection. If your hamster drags its leg or doesn’t put weight on it but you don’t see the bone sticking out, these could be signs of an internal fracture. You can treat this by allowing your pet lots of rest. Remove the hamster wheel and exercise ball, and disconnect any ladders or tubes in a multi-level cage. Feed it a healthy diet of fresh fruits and vegetables to help its leg heal. Internal fractures can take between 4 and 12 weeks to heal, so watch for signs of improvement, like walking on the leg or a reduction in swelling. For tips from our Veterinary co-author on how to prepare your hamster for surgery for an open fracture, read on!
