Objective To report incidence and relevance of positive intraoperative total hip replacement ( THR ) bacterial cultures taken at the time of surgical closure in dogs having unilateral THR . Study design Retrospective case series. Animals Dogs (n = 100) with cemented ( CFX ), cementless ( BFX ), or hybrid THR . Methods Medical records ( J anuary 2007– M arch 2010) of dogs that had THR were reviewed. Signalment, type and side of THR , concurrent surgery, operative and anesthetic times, intraoperative coxofemoral closing ( CC ) bacterial culture results, organism cultured, duration of postoperative antibiotic administration, physical examination findings at 3 weeks, 3 months, and at 6 months to 1 year after surgery, radiographic findings at 3 months and between 6 months and 1 year after surgery, and incidence of complications were retrieved. Results There was a significant difference in duration of surgery between CC culture negative and CC culture positive groups (103.27 minutes versus 122.50 minutes, respectively, P < .038) and in total anesthetic time between CC culture negative and culture positive groups (165.20 minutes versus 189.50 minutes, respectively, P < .038). There was no significant difference between CC culture negative and culture positive groups for median age (30 months versus 39 months, respectively, P < .75), median weight (36.91 kg versus 35.68 kg, respectively, P < .61), median clinical signs (4 months versus 3.5 months, respectively, P < .65), sex (males 44.32% versus females 25.00%, respectively, P < .20), laterality (left 55.68% versus right 50.00%, respectively, P < .71), concurrent surgery (extracapsular lateral imbrication/medial patella luxation/lateral patella luxation [ ECLI / MPL / LPL ] 22.73% versus none 25.00%, respectively, P < 1.00), and THR type (hybrid 17.05% versus 25.00% respectively; CFX 60.23% versus 75.0%; BFX 22.73% versus 0.0%; F isher's exact test P < .17). Conclusions Surgical and anesthetic duration were significantly associated with positive CC culture results. Positive CC culture results were not associated with adverse results at 3 months and at 6‐month to 1‐year follow‐up evaluation.
