Dogs + Surgical Conditions

  • Laser surgery is a procedure in which a beam of light energy is generated at a specific wavelength, resulting in the cutting of tissues. Laser surgery has major advantages when compared to traditional surgery, including decreased pain, decreased inflammation, and improved tissue healing.

  • The femoral head is the ball part of the hip joint and if it develops necrosis or dies, it can no longer function properly. Necrosis is due to loss of the blood supply to the femoral head, which may be the result of a growth abnormality or trauma to the hip. It is a hereditary condition of small breed dogs. The most common clinical signs are slowly progressing hind limb lameness with a resulting inability to bear weight on the affected limb or both hind limbs. Diagnosis is made by radiographs of the hip joint. The treatment of choice is femoral head and neck ostectomy, which results in a good prognosis.

  • This handout discusses lens luxation in dogs. The lens is the transparent structure within the eye that focuses light on the retina. Lens luxation is when the support ligaments of the lens weaken or break, causing the lens to dislocate from its normal position. The various types, clinical signs, heredity of the condition, diagnosis, treatment, and prognosis are outlined.

  • Lumbosacral disease, or cauda equina syndrome, is caused by the narrowing of the spinal canal and results in compression of the spinal nerve roots; pressure on the nerves that exit the spine cause the clinical signs. This pressure may be due to a narrowed spinal canal caused by arthritis, intervertebral disc herniation, an infection in the disc, trauma, congenital malformation, or a spinal tumor. Dogs with lumbosacral disease are in pain. If the clinical signs and radiographs suggest lumbosacral disease, advanced imaging such as MRI or CT is recommended to make a diagnosis. Treatment involves either conservative medical treatment or surgical intervention.

  • A luxating patella is a kneecap that moves out of its normal location. A luxating patella can be corrected surgically, especially if the patella luxates frequently. If your veterinarian performs surgery before arthritis or another knee injury occurs, the prognosis is excellent.

  • A mammary tumor is an abnormal growth in the mammary gland that develops because of abnormal replication of cells that make up the breast tissue. Mammary tumors can be benign (non-cancerous) or malignant (cancerous). This handout outlines diagnosis, treatment, management, and prognosis of malignant tumors.

  • Mast cell tumors are most common in the skin of dogs and may appear red, ulcerated, or swollen. They can be itchy and can fluctuate in size. Tumors can range from lower-grade, with minimal spread, to higher-grade, with a high risk of local invasion. Treatment usually involves surgical removal and may require supportive treatment including chemotherapy, radiation therapy, and therapy to target the mutation that instigated the tumor.

  • A meibomian gland adenoma is a benign tumor that arises from the epithelial tissue of the eyelid. These tumors start out quite small and can expand into a thick, nodular (bumpy) mass. Removal is considered curative, but the tumor can grow back if not all the affected tissue is removed during surgery.

  • Muscle tears are direct or indirect traumatic injuries that cause damage to muscle tissue. The most common cause is an indirect injury, or strain, caused by overstretching during athletic activities. This handout discusses these injuries, the clinical signs, diagnostic testing, therapy, and expected prognosis.

  • A chemodectoma is a type of tumor made up of chemoreceptor cells. Chemoreceptor cells detect chemical changes in the body and respond by regulating chemical or physical processes. These tumors are most often seen along one of the carotid arteries and the aorta. Brachycephalic breeds are more predisposed to these types of tumors, though they may occur in any dog breed. These tumors are usually locally aggressive, however, there are rare cases of metastasis to other organs, including the lungs, lymph nodes, and bone.
