In
this orthopedic case a cat was hit by a car. (By the way, almost all animal
hospital employees call these cases HBCs (Hit By Car). Veterinarians
all across America shutter when their receptionists turn to them and
say...usually about 5 o'clock on Friday afternoon..."We've got an HBC coming
right in!"
The cat's right thigh bone
(Femur) was fractured into many pieces. Fortunately the break occurred in about
the middle portion of the bone thus allowing the surgeon to stabilize the two
end fragments better than if the break occurred close to the end of the
bone.

Through an incision along the outside of the thigh, the bone fragments are inspected and in this case the surgeon elected to use a Pin and Wire Technique to fix the pieces together. Sometimes a stainless steel plate and screws will be used to hold the bone fragments together for the 2 to 3 months it will take for the bone to heal. A critical factor in any bone fracture repair mandates that the major pieces must be lined up properly, be tight together, and be held motionless long enough to allow the slow process of new bone to be laid down at the fracture. Sometimes the very tiny fragments cannot be stabilized but that generally won't be a factor as long as the major pieces are set and stabilized properly.
This X-ray clearly shows multiple bladder stones (called Cystic
Calculi) inside the bladder. These develop as a result of a wide range of
factors such as genetic physiological factors, infections in the bladder or
kidneys, and management factors such as water intake. The fastest way to get
things back to normal is to surgically remove the stones. As long as they
are in the bladder they will cause irritation and thickening of the bladder
wall, contribute to persistent bladder infections, and may even cause a
dangerous blockage of the urethra which creates an emergency situation.
Persistent urinary tract problems should always imply the need for x-rays. Long
term prevention of stone reoccurrence can be aided by specific diets that
decrease the chances of the stones developing.
Hip Dysplasia (Please be patient with the download time, a
high quality image is important!) You might ask "Do cats
get hip dysplasia, too?" The answer is yes, but this disorder is much more
prevalent in dogs than in cats. You can review a website about
Feline Hip Dysplasia for all the latest Feline
info.

Here is a nice comparison of two hips. The one on the left is a normal hip. You can see how smooth and round the head of the femur is and how nicely the "ball" fits into the "socket". A hip with this structure is very unlikely to ever develop arthritis....unlike the abnormal hip on the right. Here you can see the result of years of irritation resulting from a poor fit, a shallow "socket", and a short neck attaching the "ball" to the shaft of the femur. This severe arthritis is a result of HIP DYSPLASIA. |

This x-ray shows a large mass at one end of the spleen. The spleen is built like an elongated, thick pancake and is richly supplied with blood. Any cancer of the spleen is potentially dangerous because the mass can break open and bleed into the abdomen, plus the mass can be a source of cancer cells spreading elsewhere in the body. The usual approach is to explore the abdomen surgically and remove the spleen...if there is no evidence of any other cancer sites within the abdomen or liver. |
Esophageal Achalasia
(Scroll up to see other
x-rays while these load.)
This
disorder often has serious consequences. Resulting from a number of
possible sources, the ultimate problem is that the muscular esophagus does not
have the ability to propel food and liquids directly into the stomach. As
the swallowed material builds up in the esophagus the esophageal walls stretch
and often the food is regurgitated. Many dogs with Esophageal
Achalasia suffer from aspiration pneumonia where regurgitated food is
inhaled into the lungs and pneumonia and tracheitis results. Chronic
cough, weight loss, vomiting and discomfort await most dogs who suffer from this
disorder. It sometimes can be managed with liquid diets, feeding in a
"standing" position, and careful attention to bouts of pneumonia. The x-rays
below show you how this condition is diagnosed. It is a good example of
the use of Contrast Material in diagnostic radiology.

| This plain view is from the side and shows the chest and upper abdomen prior to swallowing any Barium. | This view is shortly after swallowing liquid Barium. Instead of immediately being propelled into the stomach by muscular contractions of the esophagus, the Barium is collecting in the weakened and non-muscular esophagus. |
