OBJECTIVES:

To determine ground reaction forces, head and pelvis vertical motion (HVM and PVM, respectively), and thoraco-lumbar lateral angular motion (LAM) of the spine using kinematic gait analysis in dogs with mild asymmetric weight-bearing of the pelvic limbs while trotting.

To gain insight into the adaptive mechanisms to tripedal locomotion and increase understanding of the biomechanical consequences of limb amputation, this study investigated kinetic and temporal gait parameters in dogs before and after the loss of a hindlimb was simulated. Nine clinically sound Beagle dogs trotted on an instrumented treadmill and the ground reaction forces as well as the footfall patterns were compared between quadrupedal and tripedal locomotion.

OBJECTIVES:

To identify environmental and management factors affecting injury rate in racing greyhounds.

METHODS:

Surveys of racing injuries at two greyhound tracks in the UK were conducted using injury data collected by track veterinary surgeons. At Track A the relative frequency of common injuries was determined and compared with previously published studies conducted in the UK. At Track B the effects of month of the year, ambient temperature and track condition ("going") on injury rate were determined.

Objectives: To develop a platform that used standard size force plates for large breed dogs to capture ground reaction force data from any size dog. Methods: A walkway platform was constructed to accommodate two force plates (60 cm x 40 cm) positioned in series to a variety of smaller sizes. It was constructed from a custom wood frame with thick aluminium sheet force plate covers that prevented transfer of load to the force plate, except for rectangular windows of three different dimensions.

Objective-To compare the 3-D motion of the pelvic limb among clinically normal dogs and dogs with cranial cruciate ligament (CCL)-deficient stifle joints following tibial plateau leveling osteotomy (TPLO) or lateral fabellar-tibial suture (LFS) stabilization by use of an inverse dynamics method. Animals-6 clinically normal dogs and 19 dogs with CCL-deficient stifle joints that had undergone TPLO (n = 13) or LFS (6) stabilization at a mean of 4 and 8 years, respectively, prior to evaluation.

Objective-To use an inverse dynamics method to describe the motion of the canine pelvic limb in 3 dimensions. Animals-6 healthy adult dogs. Procedures-For each dog, 16 anatomic and tracking markers were used to define the center of rotation for the pelvic limb joints and a kinematic model was created to describe the motion of the pelvic limb.

OBJECTIVE:

To determine if currently used ground reaction force (GRF) normalization methods are accurate and precise enough to be used on a single-limb basis.

STUDY DESIGN:

Prospective clinical trial.

ANIMALS:

Clinically normal (n = 69) dogs and 40 dogs with unilateral ruptured cranial cruciate ligaments (CCL).

METHODS:

OBJECTIVE:
To assess (2006 to 2012) conservative management for treatment of fractures of the third metatarsal bone (MT3) in racing greyhounds.
METHODS:
All racing greyhounds with MT3 fractures seen prospectively between 2006 and 2012 were included. Fracture morphology, type of conservative management, outcome and the time to a return to racing were recorded. Outcome was assessed either by communication with the trainer or by accessing the website of the Greyhound Board of Great Britain to find the complete racing history of the dog.

This study evaluated adaptations in vertical force and temporal gait parameters to hind limb lameness in walking and trotting dogs. Eight clinically normal adult Beagles were allowed to ambulate on an instrumented treadmill at their preferred speed while the ground reaction forces were recorded for all limbs before and after a moderate, reversible, hind limb lameness was induced. At both gaits, vertical force was decreased in the ipsilateral and increased in the contralateral hind limb.

Objective-To characterize injuries (on the basis of type and severity of injury and affected region of the body) among dogs participating in agility training and competition events and examine associations between injury characteristics and perceived causes of injury. Design-Internet-based, retrospective, cross-sectional survey. Animals-3,801 privately owned dogs participating in agility training or trials.
