Surgical Conditions

  • Legg-Calve-Perthes disease is also known as avascular or aseptic necrosis of the femoral head. This is a condition in which the head of the femur (the 'ball' in the ball-and-socket joint that forms the hip) spontaneously begins to degenerate. Over time, this degeneration will cause collapse of the hip and lead to arthritis.

  • Also known as acral lick dermatitis, this problem begins as an area of hair loss and reddened skin most commonly on the top of the wrist or carpal joint on the front legs. It often looks like a "hot spot." These differ from "hot spots" in that they persist despite treatment.

  • The term 'foreign body' refers to any non-food object located within the digestive tract of a dog or cat. Our pets have the tendency to play with or chew on non-food objects and, in the process of doing so, these objects can be inadvertently ingested. One especially dangerous type of foreign body, most common in cats, is referred to as a linear foreign body.

  • The patella connects the femur and the tibia and is normally located in a groove called the trochlear groove found at the end of the femur. A luxating patella is a kneecap that 'pops out' or moves out of its normal location. The patella will luxate or slip out of the groove during extension of the leg if the trochlear groove is too shallow, if the cat is bow-legged or cow-hocked, or if the point of attachment on the tibia is off-center. There are 4 grades of patellar luxation, and a higher grade means that the condition is more severe. Your veterinarian will diagnose a luxating patella by feeling the displaced kneecap during palpation of the leg. A luxating patella can be corrected surgically, especially if the patella luxates frequently. If your veterinarian performs surgery before arthritis or other knee injury occurs, the prognosis is excellent.

  • The patella, or kneecap, is normally located in a groove on the end of the femur (thighbone) just above the stifle (knee). The term luxating means out of place or dislocated. Therefore, a luxating patella is a kneecap that moves out of its normal location. Pet owners may notice a skip in their dog's step or see their dog run on three legs. Then suddenly they will be back on all four legs as if nothing happened. Many toy or small breed dogs, including Maltese, Chihuahua, French Poodles, and Bichon Frise dogs, have a genetic predisposition for a luxating patella. Surgery should be performed if your dog has recurrent or persistent lameness or if other knee injuries occur secondary to the luxating patella.

  • The gastrointestinal tract terminates in the large intestine with a tubular organ called the colon. The colon serves as a site for the absorption of water and storage of fecal material; it ends at the rectum. The walls of the colon contain muscles that are stimulated to contract by nerves from the spinal cord. When the colon contracts, fecal material is pushed out of the body.

  • Muscle tears are direct or indirect traumatic injuries that cause damage to the architecture of the muscle tissue. The most common cause is an indirect injury, or strain, caused by overstretching during athletic activities, such as running or jumping. Clinical signs of muscle tears include pain on palpation of the injured area, lameness or limping, swelling of the muscle, and/or bruising. Muscle tears are treated immediately with rest, cold compresses, and nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain, swelling, and inflammation. In the most severe cases, surgery is likely required.

  • A polyp is a benign mass, meaning that it is not malignant or "cancerous" and does not often metastasize (spread to other tissues). Nasopharyngeal polyps develop in the middle ear, which is the compartment just behind the eardrum.

  • This condition is also known as Legg-Calve-Perthes Disease, Legg-Perthes disease, Perthes disease, coxa plana, and aseptic or avascular necrosis of the femoral head.
