Denervation of the Coxo-Femoral Joint (CFJ) is a recently introduced surgical technique for the treatment of Canine Hip Displasia (CHD). Synovitis was induced by injecting sodium urate under ultrasonographic guidance in right CFJ in 6 dogs at 2 occasions, one week before surgical denervation and two weeks post denervation. Dogs were then examined for signs of pain, lameness and range of motion of both CFJs. In this study, restriction of CFJ motion and pain were the most important clinical signs after induction of synovitis. Restriction of joint motion was manifested clinically by decreased joint flexion, extension and abduction. A decrease in limb forces of the affected limb and an increase in limb forces in the contra lateral pelvic limb were noticed, while no compensatory loading of the forelimbs was detected. In the present study, selective denervation of the canine CFJ did not result in the prevention of gait abnormalities induced by sodium urate crystals. No significant differences were found when comparing kinetic and kinematic parameters measured following injection, before and after denervation. Thus, the hypothesis that selective denervation of the canine CFJ will prevent CFJ pain from sodium urate crystals induced synovitis was not accepted.
