Resumo(s)
To describe the weight-bearing compensation in working dogs with bilateral hip osteoarthritis (OA), 50
police working dogs were evaluated with a weight distribution platform at the initial evaluation and after
intra-articular treatment (a negative control 0.9% sodium chloride (NaCl), a platelet concentrate, Hylan G-F
20, triamcinolone hexacetonide or stanozolol). Six evaluation sessions were performed, over a 180-day
period. Results were compared by breed, age, sex, weight and Orthopedic Foundation for Animals hip grade
scores with the Independent Samples T-Test, repeated samples Analysis of variance and Pearson correlation
coefficient, P < .05.
Animals had a mean age of 6.5 § 2.4 years and a bodyweight of 26.7 § 5.2kg. No significant differences were
observed when comparing weight-bearing for different breeds, sex, hip grades or weight during the initial
evaluation. Significant differences were observed in deviation (P < .01) and symmetry index (P < .01)
between the control and treatment groups during the follow-up period. A weight shift from pelvic to thoracic
limbs was observed, with a weak, although a significant, correlation between a pelvic limb and the opposing
contralateral thoracic limb. Labrador Retrievers showed higher symmetry index and deviation from normal
values during the follow-up period than German Shepherd Dogs and Dutch Shepherd Dogs. Male dogs also
showed higher symmetry index and deviation compared with females. At this period, the symmetry index
showed a weak, although significant, correlation with body weight. Weight-bearing of all limbs correlated
with the remaining limbs, reflecting a more balanced weight distribution than the initial evaluation. The
weight distribution platform can be used to evaluate patients, at the initial presentation and during the
assessment of response to treatment.
