OBJECTIVES: To design a device for the conversion of linear to rotational motion and to use it in order to determine torsional properties of canine tibiae in a universal tension/compression testing machine. METHODS: A fixture incorporating a cable and pulley at one end and a guide block and rail assembly at the other was used to test 10 whole canine tibiae to failure in torsion at 1( degrees )/s. RESULTS: The device produced spiral fractures in all tibiae. Torsional strength and stiffness were 13.9 +/- 1.4 N m and 0.53 +/- 0.07 N m/degree, respectively.

OBJECTIVE: To design and manufacture custom titanium bone plates and a custom cutting and drill guide by use of free-form fabrication methods and to compare variables and mechanical properties of 2 canine tibial plateau leveling methods with each other and with historical control values. SAMPLE POPULATION: 10 canine tibial replicas created by rapid prototyping methods.

OBJECTIVE: To determine differences in bacterial strike-through for materials commonly used to cover the distal aspect of the pelvic limb during operative site preparation. STUDY DESIGN: Randomized block design; ex vivo model. ANIMALS: Canine cadaveric pelvic limbs (n=40). METHODS: Pelvic limbs (n=40) were randomly assigned to 4 treatment groups: Group 1=Vetrap+sterile Coban; Group 2=latex glove+Vetrap+sterile Coban; Group 3=latex glove+Vetrap+sterile Coban+sterile latex glove+sterile Coban; and Group 4=latex glove+Vetrap+sterile disposable drape+sterile Coban.

OBJECTIVE: To report surgical planning, technique, and long-term outcome of custom transcutaneous tibial implants used to restore ambulation after bilateral pelvic limb amputation in a dog. STUDY DESIGN: Case report. ANIMALS: A 4-year-old, 25.5 kg, female spayed, Siberian Husky. METHODS: Computed tomographic scans of the pelvic limbs were used to build sterolithographic models of the remaining tibia after bilateral amputation of the distal aspect of the tibiae. The sterolithographic models facilitated fabrication of implants that would replace the missing distal segments of the tibiae.

Surgical site infections are an inherent risk in orthopaedic surgery and many of the infections that develop are likely to be non-preventable. However, a variety of measures can be undertaken to reduce the risk and impact of surgical site infections. The development and implementation of an infection control program, including surgical site infection surveillance, can be an important tool for patient management.

In April 2004, a questionnaire was distributed to veterinary nurses across the UK to assess their attitudes towards the assessment and management of pain in practice. During the six-week collection period, a total of 541 questionnaires were returned, of which 24 (4.25 per cent) were discounted due to completion errors.

Osteoarthritis (OA) is an insidiously progressive disease producing pain and loss of function in affected joints. The suffering and restrictions on exercise that the active disease produces, make a profound impact on the quality of life of the patient. Fortunately, although the disease is widespread, estimated to affect one in five of all dogs, it is not always associated with debilitating disease [1]. Indeed it has been speculated that only animals with moderate to severe OA pathology are identified and presented as clinical problems [2].
