In June we had a Poodle Mix in our care at the San Jose Animal Care Center that had a peg leg. Essentially the dog’s right hind leg was not able to bend in a normal way so it just stuck out and got in the way and impeded her mobility.
Although there is no way to know this dog’s history, we believed that this dog had fractured the femur on the right hind leg and it was not given swift and proper care, resulting in what is known as quadriceps contracture.
The following is what the Merck Veterinary Manual has to say about the condition:
“Quadriceps Contracture (Quadriceps Tie-Down, Stiff Stifle Disease)
This serious fibrosis and contracture of the quadriceps muscles develops secondary to distal femoral fractures, inadequate surgical repair, and excessive dissection in young dogs. Adhesions develop between the bone, periosteal tissue, and quadriceps muscles, which lead to limb extension, disuse, osteoporosis, degenerative joint disease, and bone and joint deformations. Clinical signs include hyperextension and cranial displacement of the affected limb. Surgery is usually required to resect fibrous tissues and increase motion of the stifle joint. Bone and soft-tissue reconstructions along with postoperative flexion bandages and physical therapy are required to recover limb function. Prognosis is guarded. Prevention of the condition by accurate, biologic stable repairs of bone fractures is preferred.
While there are options available to treat animals with femur fractures so as to minimize or eliminate the risk of quadriceps contracture, it can happen fast (within a day) and be permanent! Fast surgical correction of the fracture paired with rehabilitation is often the key to preventing it from happening. If you are looking for a rehabilitation facility in your area, please visit the Canine Rehab Institute’s page and select Find a Therapist.
Unfortunately, this dog was not so lucky and had been living with this leg for who knows how long.
The only option for this dog was surgery to amputate the burdensome leg.
In the following two photos you can see abnormal positioning of the dog’s right hind leg. This is particularly evident when the leg is manipulated in the second photo but does not bend in a normal way, but rather remains locked.
