The Canine Sacroiliac Joint Angle: Breed Variations and Relationship to Lumbosacral, Pelvic, and Stifle Angles

Breed(s): German Shepherd Dog, Labrador Retriever
Study Type: Radiographic Study
Study Location: North Carolina State University

This joint (the attachment between the spine and pelvis) Varies widely in dogs of the same breed. It is currently unknown how this angle affects other joint angles and the development of the skeletal system in the hind limbs. We want to collect background data (x-rays) during a single visit. Without sedation, your dog will stand for radiographs of his/her pelvis. Adhesive skin markers will be placed over 6-8 anatomic landmarks and standing photographs of your dog will also be taken. The adhesive markers are easily removable. Your dog will then be laid on his/her side(s) and a radiograph will be taken of his/her tibias (bone between the knee and ankle).

Investigators are seeking normal, healthy 1-8 year old Labrador retrievers and German shepherds with no orthopedic issues.
