Correlation of spontaneous radiographic cranial tibial translation with complete cranial cruciate ligament rupture and medial meniscal tears in dogs.

The primary objective of our study was to determine the prevalence of cranial tibial translation on a single unstressed, standing angle, mediolateral radiograph of the stifle and the accuracy of diagnosing complete cranial cruciate ligament rupture in dogs with this finding using a previously published method. The secondary objective was to determine if there was a higher incidence of meniscal injuries associated with spontaneous radiographic cranial tibial translation as previously proposed. Medical records were reviewed for client owned dogs with cranial cruciate ligament rupture that underwent surgical stabilization with intra-operative evaluation of the stifle joint via arthrotomy between June 2013 to January 2022 and had pre-operative radiographs performed within 60 days prior to surgery. Pre-operative radiographs were evaluated for cranial tibial translation via the previously published method. Three hundred twenty-three dogs met the inclusion criteria for the study. Intra-operative findings and radiographic assessments were evaluated for correlations. Cranial tibial translation on pre-operative standing angle radiographs detected cranial cruciate ligament tears in 24.8% of cases but had a positive predictive value of 97.5% for diagnosing complete cranial cruciate ligament rupture with a specificity of 95.4% and an overall accuracy of 36.8%. Meniscal tears were present in 58.75% of cases with radiographic cranial tibial translation and 41.25% of cases without. There was no significant increase in the incidence of meniscal tears between the two groups. The presence of radiographic cranial tibial translation in dogs on an unstressed, standing angle, mediolateral radiograph of the stifle is diagnostic for cranial cruciate ligament rupture, but cannot be used to determine the presence of a meniscal tear.

A novel dextran polymer hydrogel local antimicrobial therapy in dogs: A pilot study.

Our purpose was to evaluate physical, laboratory, and/or radiographic abnormalities associated with a novel dextran polymer hydrogel local antimicrobial agent impregnated with amikacin and clindamycin in dogs having tibial plateau leveling osteotomy implants removed due to suspected surgical site infection. A total of 28 client-owned dogs were enrolled and 20 completed the study. Routine plate explantation and bacterial cultures were performed and the polymer hydrogel was applied to the surgery site. No systemic antimicrobials were used after surgery. Serum biochemistry, hematology, urinalysis, physical examinations, and radiographs were monitored before surgery and up to 12 wk after surgery. Sixteen of the 20 dogs (80%) had a positive bacterial culture, 44% of which were methicillin resistant. There were no significant alterations of laboratory values, physical examination, or radiographs to indicate adverse reactions to the polymer hydrogel. There were no signs of inflammation or infection in any patient at the 12-week postoperative recheck.

Thérapie antimicrobienne innovatrice locale à l'hydrogel de polymère de dextrane chez les chiens : étude pilote. Notre but consistait à évaluer les anomalies physiques, de laboratoire et/ou radiographiques associées à un nouvel agent antimicrobien local d'hydrogel de polymère de dextrane imprégné d'amikacine et de clindamycine chez les chiens dont les implants d'ostéotomie de nivellement du plateau tibial avaient été enlevés en raison d'une infection suspectée du site de la chirurgie. Un total de 28 chiens appartenant à des clients ont été recrutés et 20 ont fait partie de l'étude. Une explantation de routine de la plaque et des cultures bactériennes ont été réalisées et l'hydrogel de polymère a été appliqué au site de la chirurgie. Aucun antimicrobien systémique n'a été utilisé après la chirurgie. Une biochimie sérique, l'hématologie, l'analyse d'urine, des examens physiques et des radiographies ont été réalisés avant la chirurgie et jusqu'à 12 semaines après la chirurgie. Seize des 20 chiens (80 %) avaient une culture bactérienne positive dont 44 % était résistante à la méthicilline. Il n'y avait aucune altération importante des valeurs de laboratoire, de l'examen physique ou des radiographies pour indiquer des réactions indésirables à l'hydrogel de polymère. Il n'y a eu aucun signe d'inflammation ou d'infection chez aucun patient lors d'un examen postopératoire à 12 semaines.(Traduit par Isabelle Vallières).
