The ability to diagnose the cause of a lameness is essential to the small animal clinician. In our day to day practice settings, dogs and cats present with a variety of lamenesses. Many of these problems resolve with rest, or a diagnosis is readily available (cut pad, ingrown nail, etc?).
Urine diversion techniques are performed to temporarily or permanently divert urine from its normal anatomic course from the kidney through the ureter to the bladder and finally through the urethra. Veterinarians are most familiar with temporary urine diversion (urethral catheters) that are often used to stabilize animals that are sick as a result of metabolic changes associated with urinary tract obstruction.
Rabbits should be spayed anytime after 5 months of age. When very young, the uterine horns and ovaries are very tiny making identification challenging. However, in older mature and perhaps overweight rabbits, the mesometrium is extremely fatty and friable. OVH is indicated in all female rabbits to prevent pregnancy, control territorial aggression, prevent uterine neoplasia (80% incidence), or other uterine disorders such as pyometra.
Laryngeal paralysis is a congenital or acquired disease that causes upper airway obstruction. Paralysis causes partial or complete obstruction of the laryngeal lumen due to denervation of the cricoarytenoideus dorsalis muscle of the larynx. Interruption of nerve transmission from the recurrent laryngeal nerve or the vagus results in failure of the arytenoid cartilages and vocal folds to abduct on inspiration.
The pinna of the external ear may vary a great deal between breeds. There are two cartilage segments that support the external ear and the ear canal. The auricular cartilage forms the pinna, the base of the ear, the horizontal and part of the vertical canal. The annular cartilage acts as the framework for the vertical canal and is attached to the external acoustic process and the auricular cartilage.
This text is not intended to cover each and every aspect relating to wounds presented in veterinary medicine. It is, however, designed as a simplified handbook, which will assist members of the veterinary medical team in properly assessing patients and their wounds.
Traumatic fragmented medial coronoid process (TFMCP) is a condition in the elbow joint of dogs that appears to occur commonly in performance dogs. Unlike the classic condition of fragmented medial coronoid process (FMCP) affecting the elbow joints of skeletally immature large to giant breed dogs, jump down syndrome (TFMCP) appears to have no age or size limitations.
While considered a very common problem in small animal medicine, osteoarthritis is very likely the most under diagnosed, and misunderstood rheumatic disease in dogs and cats. Part of the problem veterinarians face with OA is that it is a slow, progressive and often insidious problem.
It is important to understand that when a dog presents with a dog with hip laxity (hip dysplasia) with or without secondary degenerative changes, that there is not one single way to manage every patient. Initially, one must decide if a particular patient is better suited for medical or surgical options.
Current treatment options for osteoarthritis are extensive and can be categorized into medical/ conservative or surgical therapies. Medical therapies may consist of weight control, exercise modification, rehabilitation therapy, pain management medications, oral joint protective compounds, and intra-articular treatments.
The most common hind limb orthopedic/sports medicine conditions afflicting active dogs are iliopsoas strains, cranial cruciate ligament (CCL) insuffiency and gracilis and semitendinosus contracture. Of the hind limb muscular injuries iliopsoas strain is, by a considerable margin, seen more frequently than gracilis and semitendinosus contracture.
There are numerous studies indicating the positive benefits of rehabilitation therapy following CCL surgery. In summary, rehabilitation therapy has been shown to improve muscle mass and attenuate muscle atrophy that occurs in the post-operative period, increase stifle joint ROM, especially extension, improve weight-bearing as measured by force plate analysis, and reduce the progression of osteoarthritis.
Soft tissue injuries and osteoarthritis are common conditions afflicting active dogs due to the repetitive forces placed on the joints. Microtrauma to the tendons, ligaments, and the articular surfaces of joints can occur, creating an environment for osteoarthritic development.
Megacolon occurs more frequently in cats than dogs and is usually seen in middle-aged to geriatric cats. The ascending, transverse, and descending colon are chronically large in diameter and filled with dry stool. A congenital form of the disease has been seen especially in Manx cats with rectal/anal atresia and a sacral spinal deformity.
Metallic implants placed in the body should be corrosion-resistant, biocompatible, and must have adequate strength to withstand functional stress. Corrosion of metal occurs because of the electrochemical ions in body fluid. Most metal implants currently used in veterinary surgery are of 316L stainless steel.
Similar to dogs, joint disorders of the cat are common. Despite this fact, the reported treatment options for cats with joint disease are limited. The object of this presentation is to describe the clinical findings, surgical / arthroscopic findings and post-operative management of cats with joint disorders including elbow osteoarthritis and medial compartment disease, shoulder osteoarthritis and medial shoulder instability, and cranial cruciate ligament insufficiency.
Careful consideration of preoperative, intraoperative, and postoperative management techniques will assist in preventing complications related to anesthesia and surgery in patients with urinary tract surgical disease. Hospital acquired renal insufficiency is common in humans, seemingly less so in animals but caution is advised. Hypotension of any cause is a potential predisposing cause to renal failure.
Diagnosing and treating forelimb conditions in dogs can be very challenging. Many dogs present with a similar history including minimal responsive to rest and non-steroidal anti-inflammatory drugs and increased lameness following exercise and heavy activity. It can be difficult to localize the lesion on palpation as many dogs may show increased sensitivity in the shoulder and elbow from referred pain and compensation.
A working definition of antimicrobial prophylaxis in surgery is the administration of an antimicrobial drug to a patient, in the absence of infection, prior to surgery. The history of the use of these agents during surgery is interesting and reveals many of the problems which occur with their use.
A systematic approach can help ensure safety.
Four studies on treating joint disease.
A roundtable discussion of joint health and disease in dogs and cats.
Owners and veterinarians often seek additional therapies for dogs with osteoarthritis that are safe and effective.
Tube drainage of the thorax is indicated to drain free air or fluid in the pleural space. This is not an absolute indication as small amounts of air within the thorax do not require a thoracostomy tube. Similarly, the presence of blood within the pleural space is not usually an indication for thoracic drainage.
Surgical fenestration of the intervertebral space provides a means of prophylaxis on disk disease. If protrusion exists, surgical removal of the nucleus remaining in the intervertebral area will eliminate the pressure causing the protrusion.
