What are Tibial Tuberosity Avulsion Fractures?

Tibial tuberosity avulsion fracture usually occurs in younger dogs due to the area of the tibia not being fully fused to the rest of the bone. Puppies diagnosed with this type of fracture usually have had some sort of trauma such as falling from a couch or bed and landing with the knee flexed. This can tear the bone fragment from its normal position. If left untreated, a tibial tuberosity avulsion fracture can result in poor function of the knee joint or the entire leg.

Young puppies of any breed can be susceptible to tibial tuberosity avulsion fractures. Small breed dogs, especially toy breeds of any age can also have a tibial tuberosity avulsion fracture occur if they fall or jump off of furniture or steps.

The tibial tuberosity attaches the patella to the tibia with a strong tendon of the quadriceps muscle group. A fracture of the tibial tuberosity can result in an avulsion fracture and pull the quadriceps muscles. An avulsion fracture happens when a bone has been broken and a fragment of the bone is being separated by the pull of an attached muscle or tendon.

Symptoms of Tibial Tuberosity Avulsion Fractures in Dogs

Dogs, especially puppies, can come up with bumps and bruises from any number of causes. However, if you notice that your puppy or young dog has taken a spill and is not acting like his normal self, call your veterinarian for an assessment. Any of the following symptoms should be taken seriously and your dog should immediately see a veterinarian.

  • Sudden onset of lameness on a hind leg 
  • Refusing to bear weight on a hind leg
  • Pain in the joint or leg on a hind leg
  • Swelling around the front of the knee joint on a hind leg

Causes of Tibial Tuberosity Avulsion Fractures in Dogs

Tibial tuberosity avulsion fractures are caused by some form of trauma. They can be difficult to prevent, however, some preventative measures can be taken such as not allowing puppies or small dogs on furniture unsupervised. 

Be careful not to drop puppies or small breeds of dogs when holding them and never allow them to jump on or off furniture. If you have a lot of steps in your home, pick your puppy up and carry them up or down the stairs.

Diagnosis of Tibial Tuberosity Avulsion Fractures in Dogs

When you take your dog in for an examination by your veterinarian, provide as much information as possible including medical history and if you witnessed falls or stumbles. Your veterinarian will perform a physical exam and an orthopedic evaluation to determine the extent of damage that has been done.

Your veterinarian will palpate the injured leg. The leg will be painful to your dog when it is flexed or extended. Swelling may be present and the patella may be higher than usual since it is no longer attached firmly to the tibia.

X-rays and other imaging scans will give a definitive diagnosis. Both legs will be x-rayed so a comparison can be made and the exact displacement of the bone fragment can be found.

In most instances, the tibial tuberosity avulsion fracture is the only medical problem, therefore, blood work will only be needed in the event of surgery. Any dog undergoing general anesthetic should have blood work completed to ensure that they are healthy enough to undergo surgery.

Treatment of Tibial Tuberosity Avulsion Fractures in Dogs

Generally, for a tibial tuberosity avulsion fracture, surgery is the best treatment. Some veterinarians may opt to rest the leg if the avulsion fraction does not look severe to give the swelling a chance to subside. Casting the leg may also be an option if the displacement is minimal.

Surgery will entail putting the bone back into its correct position to keep the quadriceps muscles from continuing to pull the bone fragment out of place. Your dog will be placed under anesthesia and pins and/or wire will be used to correct the fracture. After the bone has been put back into place x-rays will be taken to ensure that the realignment of the bone is correct.

Recovery of Tibial Tuberosity Avulsion Fractures in Dogs

Post surgery care will be required and some veterinarians will expect your dog to remain at the hospital overnight or for a few days for close monitoring. A padded bandage on the leg will be required to keep the incision site clean. Anti-inflammatory medications and antibiotics may be prescribed as well as pain medications.

During recovery from surgery, swelling or redness need to be watched for and any abnormal drainage from the incision site to ensure that the wound is healing properly. If you notice anything unusual, contact your veterinarian immediately. Stitches or staples will be removed about 10 – 14 days following surgery. Exercise should be kept minimal for about 6 weeks following surgery. Your veterinarian will give you detailed instructions that need to be followed exactly to ensure that your dog fully heals from the tibial tuberosity avulsion fracture and the consequential surgery.

My pet has the following symptoms:
Pain When Lifted
Hi, my Dog has just been diagonised with possible Tibial Avulsion Fracture. It is only quite small but he is a large dog. The vet recommeded two options surgery and conservative treatment. What exactly is the conservative treatment and what would be recommended over the two?

Thank you for your question. Tibial avulsions will likely not heal with conservative therapy, and surgery is typically recommended. With the constant force of the ligament pulling on the fracture, it doesn't heal on its own. I hope that all goes well for him.

My pet has the following symptoms:
Bilateral Tibial Tuberositu Avulsion
Is surgery the only option we have in terms of his fracture? It’s just too much to pay and we don’t want to have to put him down.

Thank you for your question. Unfortunately, the treatment for that type of fracture is surgery, as there is too much tension on the bone to be able to splint it. Since I don't know anything about your dog's fracture or situation, it would be best to seek a second opinion from another veterinarian, if you're not sure, as that is a big decision. I hope that everything goes well for your dog.
