OBJECTIVE: To investigate the correlation between radiographic hip grade and kinetic parameters in German shepherd dogs. METHODS: Dogs were distributed into five groups of eight dogs each according to hip grade (A, B, C, D or E). Dogs were submitted to clinical evaluation and kinetic analysis. Five valid passages were analysed using data collected from a pressure walkway. Peak vertical force, vertical impulse and stance phase duration were evaluated at velocity (1 · 2 to 1 · 4 m/s) ±0 · 1 m/s(2) acceleration. Kinetic data between groups were compared. RESULTS: In pelvic limbs, mean peak vertical force decreased progressively from grade C (mild) to grade E (severe) hip dysplasia. The vertical impulse was decreased in groups C and E compared to groups A, B and D; stance phase duration did not differ significantly between groups. CLINICAL SIGNIFICANCE: Mean peak vertical force was lower in dogs with severe hip dysplasia compared with mildly dysplastic dogs. These results suggest that hip dysplasia degree can affect lameness severity.
