Abstract:
The hypothesis that dogs with osteoarthritis in the elbow joint showed very complex changes in their vertical force distribution of the individual paws compared to healthy dogs was confirmed. The aim of this study was to compare the paws of 23 dogs with osteoarthritis in the elbow joint and 22 healthy dogs relating to peak vertical force (PFz), vertical impulse (IFz) and time of occurrence of maximum vertical force within stance phase (TPFz) using a pressure plate by dividing the paws into four quadrants.The vertical forces in the paw of the lame anterior extremity was significantly lower, but not equally compensated by all extremities: PFz was lower in all quadrants of the lame anterior extremity except the caudo-medial quadrant, IFz was lower in both cranial quadrants only than in healthy dogs. The compensation of lameness by the other extremities was also complex: The contralateral anterior extremity compensated by additional loading of the two caudal quadrants, the posterior extremities compensated by additional loading of the caudo-medial quadrants, whereas the cranio-medial quadrants were less loaded. Referring to IFz, the caudo-lateral quadrant is additionally loaded more. Both anterior extremities reached TPFz later in almost all quadrants.This study is the first study, which uses the system of dividing the paws into four quadrants for an orthopedic disease and contributes an important input to further comparisons with other orthopedic diseases and an examination method that can also be used for more accurate diagnostics of the various orthopedic diseases.
