Occasionally, cats’ teeth do not erupt in the right location, resulting in pain and poor function. Treatment options include orthodontic appliances to move the teeth, extraction, or crown amputation with restoration. Many veterinarians are comfortable delivering orthodontic care for cats. Your veterinarian may seek the advice of a board-certified veterinary dental specialist for advice or referral.

Supportive braces can help dogs with many orthopedic conditions, including skeletal deformities, carpal hyperextension, and cruciate ligament disease. It is important to have any brace properly fitted to avoid complications. Braces are not considered equivalent to surgery for cruciate ligament disease.

Osteochondritis dissecans is an inflammatory condition that occurs when diseased cartilage separates from the underlying bone. It most commonly affects the shoulder joint but the elbow, hip, or knee (stifle) may also be involved. This is a developmental disease that occurs in rapidly growing large breed dogs typically between 6 and 9 months of age and tends to occur more often in male dogs. Dogs that are affected with OCD typically limp or are lame in the affected leg or legs. Several radiographs of each affected leg are necessary to get an accurate assessment of various bones and joints. Treatment may involve conservative medical management or surgical intervention.

Osteochondrosis (OCD) is a failure of the bone underlying the smooth articular cartilage inside the joints, i.e. the subchondral bone, to form properly from the skeleton's cartilage template.

Osteosarcomas are somewhat rare in cats and progress slowly. Osteosarcoma is very painful. The most common location where osteosarcomas develop in cats is the hindlimb. Amputation is by far the most common treatment. Chemotherapy is not generally pursued without evidence of metastasis, given the relatively long-term control with surgery alone.

Osteosarcoma, or bone cancer, is common in large breed dogs and is very aggressive, with upwards of 90-95% of patients having micrometastasis. Osteosarcoma is very painful. Lameness or a distinct swelling may be noted. Amputation is by far the most common treatment with chemotherapy following surgery. Radiation therapy may also be an option.

Rarely, ovarian tissue can be left behind when a cat is spayed. This leads to the ongoing secretion of hormones such as estrogen and progesterone that can result in a cat continuing to have a heat cycle. Ovarian remnants are difficult to diagnose but vaginal cytology, combined with hormone testing, can be used to confirm the presence of functional ovarian tissue. Surgical treatment is typically recommended to prevent other health conditions from developing.

Ovarian tumors are quite rare in North American pets, mainly due to routine spaying practices. This handout discusses ovarian tumors in dogs and cats. The various forms of ovarian tumors, clinical signs, diagnosis, treatment, and prognosis of this cancer are outlined.
