Attenuation From Shoes and Pads in Equine Nuclear Scintigraphy, With Relevance to Solar Views.

Nuclear scintigraphy can be beneficial in the investigation of equine lameness and poor performance. Images obtained through the sole allow for better identification of a region of increased radionuclide uptake in the foot. The presence of shoes or pads may affect these images.

Treatment of subchondral lucencies in the medial proximal radius with a bone screw in 8 horses.

Objective: To describe the results of screw placement through subchondral lucencies (SCL) of the proximal radius in 8 horses.

Study Design: Retrospective clinical study.

Animals: Horses with cubital SCL causing lameness (n=8).

A mechanical study of ligature security of commercially available pre-tied ligatures versus hand tied ligatures for use in equine laparoscopy.

Objective: To determine a hand-tied ligature knot configuration, suture size, and suture type that would be an acceptable substitute to commercially available ligature knots for use in equine laparoscopic surgery.

Study Design: Three-factor ANOVA with the fixed effects being suture type, suture size, and knot type. The dependent variable was ligature security (load to failure).

Rupture of the peroneus tertius tendon in 27 horses.

The purpose of the study was to identify factors influencing the outcome and prognosis of rupture of the tendon of the peroneus tertius muscle in 27 horses. Information on history, physical examination findings, diagnosis, treatment, and final outcome was summarized from medical records. Long-term follow-up information on horses was obtained by telephone survey.

Gastrointestinal endoscopic surgery.

A working knowledge of normal endoscopic anatomy and the effects of positioning must be mastered to take advantage of endoscopic procedures involving the gastrointestinal system. Endoscopic procedures involving the gastrointestinal system offer advantages over conventional surgery in that they are less invasive and provide direct visualization. Laparoscopy can be used to evaluate horses with abdominal pain before and after surgery.

The effects of ethylene oxide and gas-plasma sterilization on failure strength and failure mode of pre-tied monofilament ligature loops.

Objective: To evaluate the effects of ethylene oxide and gas-plasma sterilization on the failure strength and failure mode of pre-tied monofilament ligature loops.

Study Design: A randomized block design was used by blocking for suture (size 1 polyglyconate, size 2 polydioxanone) and sterilization technique (control, ethylene oxide, gas plasma).

Sample Population: Twenty replicates of each suture-sterilization technique combination.

An in vitro biomechanical comparison of two interlocking-nail systems for fixation of ostectomized equine third metacarpal bones.

Objective: To compare the mechanical properties of 2 interlocking-nail systems for fixation of ostectomized equine third metacarpi (MC3): (1) a standard interlocking nail with 2 parallel screws proximal and distal to a 1-cm ostectomy; and (2) a modified interlocking nail with 2 screws proximal and distal to a 1-cm ostectomy with the screws offset by 30 degrees.

Animal Or Sample Population: Twelve pairs of adult equine forelimbs intact from the midradius distally.

Methods: Twelve pairs of equine MC3 were divided into 2 test groups (6 pairs each): torsion and caudocranial 4-point bending.

Treatment of methicillin-resistant Staphylococcus epidermidis infection following repair of an ulnar fracture and humeroradial joint luxation in a horse.

A 27-month-old Rocky Mountain Horse was examined because of a fracture of the proximal portion of the ulna and luxation of the humeroradial joint (Monteggia fracture). Open reduction was performed, using a mechanical distractor, and the ulnar fracture was stabilized by application of a bone plate and screws. After surgery, the horse developed an infection of the surgical site, and bacterial culture of fluid from the surgical site yielded a pure growth of methicillin-resistant Staphylococcus epidermidis susceptible to oxytetracycline, erythromycin, rifampin, and vancomycin.

Diagnosis and surgical repair of patellar luxations in a flock of sheep.

Eleven sheep with a common ancestry were evaluated for clinical signs of hind limb lameness. Physical examination revealed advanced forms of patellar luxation. Radiography confirmed the diagnosis of patellar luxation; flexed dorsoproximal-dorsodistal radiographic views were obtained and revealed hypoplasia of the femoral trochlea.

Ultrasonographic appearance of exogenous isobutane gas in the mammary glands of dairy cows.

Objective: To determine whether exogenous isobutane gas infused into the udders of dairy cattle could be detected ultrasonographically, and if so, what effects volume of gas infused and infusion pressure had on how long after infusion exogenous isobutane gas could be detected.

Design: Randomized block design.

Animals: 8 Holstein cows 28 to 32 days after parturition.

Cardiopulmonary changes associated with abdominal insufflation of carbon dioxide in mechanically ventilated, dorsally recumbent, halothane anaesthetised horses.

The use of laparoscopy for the diagnosis or therapeutic management of abdominal disease in the horse has distinct advantages when it allows the horse to remain standing. However, distending the abdomen by insufflation of a biologically active gas in an anaesthetised horse may add to the physiological challenge of general anaesthesia and recumbency. The cardiopulmonary responses to abdominal insufflation with carbon dioxide (CO2) to 15 mmHg pressure were evaluated in 6 horses in dorsal recumbency anaesthetised with halothane in oxygen and subjected to laparoscopic colopexy.

Laparoscopic colopexy in horses.

Objective: To describe a technique for laparoscopic colopexy in horses.

Study Design: Description of a technique to perform laparoscopic colopexy in horses.

Animals: Six healthy adult horses between 3 and 23 years of age and weighing between 440 and 636 kg.

Clinical and radiographic findings, treatment, and outcome in cattle with osteochondrosis: 29 cases (1986-1996).

Objective: To summarize the radiographic and clinical findings, treatment, and outcome in cattle with osteochondrosis diagnosed radiographically.

Design: Retrospective case series.

Sample Population: 29 cattle with radiographic evidence of osteochondrosis.

Isolation of methicillin-resistant Staphylococcus aureus from a postoperative wound infection in a horse.

Methicillin-resistant Staphylococcus aureus (MRSA) was isolated from a postoperative wound infection in a horse. Methicillin-resistant S aureus infections in animals have been reported. In human beings, MRSA is an important cause of hospital-acquired (nosocomial) infections.

Management of a transverse fracture in the distal phalanx of a horse.

A yearling horse was presented with a septic, transverse fracture in the frontal plane of the distal phalanx. The fracture fragment was surgically removed from the parent bone via the sole. The foot was managed by corrective farriery and the horse was able to be ridden for pleasure.
