Excision Arthroplasty of the Hip Joint in Dogs: The Role of Age, Weight, Degenerative Joint Disease on the Outcome.

The present clinical study was to evaluate the relationship between weight, degenerative joint disease (DJD) and age on the outcome in dogs underwent excision arthroplasty operation. 105 dogs have been referred to clinic with lameness on hindlimb. Dogs were younger than 1 year (50 dogs), 1 to 5 years (24) and older than 5 years (31). The rest of them were less than 10kg and the rest were heavier than 10kg. Lameness during walking was scored between zero to 5. Radiographic findings were showed that degenerative joint change, hip dysplasia and luxation. Excision arthroplasty of the hip joint was performed. Walking status was examined postoperatively. Intra-group data showed in dogs younger than 1 year, weight was not an effective factor, and association between DJD and the outcome was statistically significant in both weights. DJD had effective role in dogs more than 10kg in comparison to less than 10kg. The association between DJD and the outcome wasn't statistically significant in dogs 1 to 5 years in both weights. In elder dogs, weight wasn't a main factor, and association between DJD and outcome was statistically significant in both weights. In latter group, DJD had effective role on the outcome in dogs less than 10 kg in comparison with more than 10 kg. The authors suggest the weight is not as much effective as age among groups of study after Excision arthroplasty of the hip joint. [ABSTRACT FROM AUTHOR]
