Due to the fact that birds have small, and sometimes hollow bones, it is not unusual for them to break them due to trauma. Falling off a perch, being injured by another animal, or even being stepped on by its owner are some of the more common causes of a fracture. Sometimes there are underlying problems causing the bones to be weak and susceptible to fracture during normal activity. The tibiotarsal (shin bone) is the one most commonly fractured.
This page shows a tape splint on a simple fracture. This splint is light and stable, perfect for a small bird like a budgie (parakeet) or a cockatiel. At the end of this page you will see fractures that need surgery, with a link to seeing the full surgical repair of a fractured femur (thigh bone) in a rabbit at our hospital.
Most birds that have broken legs will not bear weight on the affected leg. Most fractures can be palpated by one of our doctors, although a bone can be fractured without any obvious evidence during examination. Taking a radiograph is one of the best methods to determine if a fracture is present.
Do you see the fracture in this view?
The fracture is more apparent in this side view. This emphasizes the importance of taking two views. This fracture is classified as a mid shaft transverse fracture of the tibiotarsal bone.
Most tibiotarsal bones heal well when splinted with special tape. We usually keep the splint on for one month, although this varies. On occasion we need to perform surgery for proper stabilization. This is more common when there is a fracture of the femur (thigh bone).
The first layer of tape is applied directly to the skin. We use a type of tape that will cause minimal irritation to the sensitive skin during the healing process and when we remove it after the bone has healed.
These tape strips are molded over the leg to provide the beginning stages of stability. Several pieces are used to cover above and below the fracture.
The next layer of tape is waterproof and much stronger. Several strips are used to provide the necessary stability.
When all the layers of tape are applied a hemostat is used to gently mold all the layers tight up against the bone. Now the fracture site is stable and the bone can begin the healing process.
One our doctor feels the bones are lined up properly and the fracture site is stable, the excess tape is trimmed.
The splint is trimmed for easier mobility. With the fracture stable this bird will feel substantially better, and start bearing weight very soon. It needs to remain quiet and not climb or play excessively during the healing process. The foot should be checked daily for swelling and the splint should be kept clean and dry (of course it is OK to sign the splint). Weekly rechecks by one of our doctors will ensure the splint is secure and the foot is not swelling.
This budgie also had a broken tibiotarsal bone that was repaired with a tape splint
For comparison purposes this is a cast put on a wiggly 6 year old boy named Mike. As you can see, one of his fans is signing the cast while he enjoys some R & R. Your bird needs the same kind of attention during its healing process. Make sure it gets plenty of rest and good nutrition, and remove perches initially so it can not climb around the cage. Putting something soft in the bottom of the cage is also needed.
Some tibiotarsal fractures will not heal with a tape splint.
These are typical of bird fractures that require surgery
This is not a bird tibiotarsal fracture. It gives you an idea of how we might use pins on a bird
We would like to use plates on birds fractures like other animals. Bird bones are too thin, and the plate is too heavy, to use in a bird.
This is a rabbit femur fracture
