Fracture of the Carpus (Wrist) and Tarsus (Ankle) in Cats

Fracture of the Feline Wrist and/or Ankle in Cats

Isolated fractures of the bones of the carpus (wrist) or tarsus (ankle) are not frequently encountered in veterinary medicine. More commonly these fractures are found in conjunction with other fractures or shearing injuries (where the tissues are ground off on a hard surface) of the legs.

These fractures are usually the result of trauma and often cause a severe lameness of the affected limb. The lameness may improve with time and rest such that it becomes obvious only with exercise.

The potential long-term effects of these fractures range from none to severe, debilitating arthritis in the joint.

Diagnosis Fracture of the Carpus and Tarsus in Cats

Diagnostic tests are necessary to determine the presence of the fracture and assess its location and severity concerning how many fragments are present and association of the fracture with the joint and/or ligaments. In addition to obtaining a complete medical history and performing a thorough physical examination, tests that your veterinarian may wish to perform include:

Treatment of Fracture of the Carpus and Tarsus in Cats

There are many bones that make up both the carpus and tarsus. Depending on the nature of the specific fracture, management may be different for each case. Treatment of these fractures may include the following:

Home Care and Prevention

If immobilization of the joint in a split or a cast is the sole form of treatment for these fractures, you will need to restrict your cat’s activity for several weeks. The toes will be visible at the bottom of the splint or cast and you will need to touch and squeeze them daily to make sure they are warm, non-painful and not excessively swollen. The splint will need to be redressed or changed approximately every two weeks (or sooner if it becomes wet or soiled, or if your cat develops any rub sores at the top or bottom of the splint). Contact your veterinarian if you have any questions or concerns regarding your cat’s splint or cast.

Regardless of whether the affected leg is placed in a cast or repaired by surgery, your cat needs to be kept restricted from activity for several weeks. Depending on the type of surgery, a skin incision may be visible. Monitor the incision for swelling, redness or discharge. Stitches or staples will need to be removed in 10-14 days after the surgery.

A re-check appointment with your veterinarian will usually be scheduled for several weeks after your cat was released from the hospital. Your veterinarian will perform radiographs to evaluate how the bone is healing and will monitor your cat’s progress before allowing you to increase his activity level.

Many traumatic events are true accidents and thus unavoidable; however, you can avoid the risk of having your pet sustain motor vehicle trauma by keeping cats at home where it is safe.
