Abstract Objective The aim of this study was to identify risk factors for an agility dog becoming injured during its career. We hypothesized that certain factors involved with the training, competition, age, sex, age of neuter, body condition, and management could be associated with the risk for injury. Study Design The outcome of interest in this cross-sectional survey design was injury versus no injury, and an initial univariable analysis screening was performed. All variables with a p-value of less than 0.20 in univariable analysis were entered into a multivariable logistic regression model. Manual backward stepwise removal was performed until remaining variables had a p-value of less than 0.05. Results Five-hundred responses were included in the analysis. In the final multivariable model adjusting for all other variables, breed, age, age at neuter, and level of competition remained associated with injury in the study population. Conclusion These findings support existing literature on the predispositions for injury with certain breeds and competition level. Our study further suggests, however, that there is a need to better understand how health decisions earlier in life may affect the prevalence for injury in the agility competitor, particularly regarding age at neutering and age of the competitor.

Abstract A 32-month-old female Labrador Retriever mix-breed presented for right pelvic limb lameness with firm swelling on the lateral aspect of the stifle. Radiographs revealed a mass with periosteal elevation along the lateral cortex of the proximal tibia. Histology on a core biopsy sample was diagnostic for osteosarcoma. Surgical treatment was declined. Eight months post diagnosis, the patient was re-evaluated by the primary care veterinarian and had no lameness, pain, or tibial swelling. Sixty-three months later (5.2 years), the patient presented for cranial cruciate ligament ruptures. Radiographs revealed a smooth bony protuberance on the lateral aspect of the right proximal tibia in the area of the previous osteosarcoma. The patient underwent bilateral tibial plateau levelling osteotomies. The surgical recovery was uneventful with normal healing. Twenty-seven months following surgery, the patient returned for painful swelling around the right proximolateral tibia. Radiographs revealed an 8 × 9 cm osteoproliferative and osteolytic lesion of the proximal tibia. Osteosarcoma was confirmed via core biopsy. The bone tumour grew rapidly, and the patient was euthanatized 3 months thereafter. This case report demonstrates the unusual occurrence of an osteosarcoma in a young dog which spontaneously regressed. Ninety months (7.5 years) after clinical resolution of the initial tumour, osteosarcoma formed again in the same location. Lifetime patient monitoring with repeated clinical exams, serial radiographs, and multiple biopsies by the same surgeon, pathologists, and radiologist are unique features of this case report.

Abstract A 10-year-old Labrador Retriever was referred for persistent lameness due to chronic right shoulder pain, unresponsive to various pain management therapies. Radiographs indicated signs of severe degenerative changes in the joint. Synovial fluid analysis was not diagnostic. Septic arthritis was suspected based on computed tomography and clinical signs. Arthroscopy allowed joint exploration, tissue biopsies, and copious joint lavage. Trichophyton spp. proliferation was identified on antimicrobial culture and histological analysis on samples obtained during arthroscopy. Oral griseofulvin therapy was initiated. Two months later, the referring veterinarian decided to interrupt the treatment after a negative synovial culture despite persistent lameness. Euthanasia was elected upon after pain also appeared on the tarsus; a post-mortem exam was not authorized by the owner. The origin of the infection remains unclear as this patient had no skin lesions and its immunological status was unknown. However, dermatophytosis has been reported in healthy dogs without skin lesions. To the author's knowledge, this is the first report of an osteoarticular infection with a dermatophyte in a dog.

Abstract Medial patellar luxation is a multifactorial condition resulting from a misalignment of the stifle extensor mechanism. Several techniques have been described for correcting this condition, depending on the specific morphological changes identified. This case series describes the combination of tibial tuberosity transposition tool techniques and distal lateral femoral closing wedge osteotomy in the treatment of dogs with medial patellar luxation. A combination of these two techniques was used in five dogs with varying degrees of medial luxation of the patella resulting from distal femoral varus and less than 20 degrees distal external torsion of the tibia. The combination of techniques allowed the alignment of the stifle extensor mechanism and corrected medial patellar luxation in all dogs. Radiographic bone union occurred in all dogs, with a mean time of 30 ± 2 days for tibial osteotomy and 48 ± 16 days for the femur. There was no recurrence of patellar dislocation, and no complications developed in any animal during a 1-year-long observation period. This case series demonstrates that the combination of tibial tuberosity transposition tool techniques and distal lateral femoral closing wedge osteotomy can be an effective treatment for medial patellar luxation associated with distal femoral varus with external tibial torsion less than 20 degrees.

Abstract The aim of this study was to report the surgical treatment of stifle joint luxation through temporary immobilization of the joint with locking plates in a cat. Stifle joint was immobilized using a temporary trans-articular locking plate applied medially. Return to function was assessed by physical and radiographic follow-up examinations. The cat had good return to function despite a reduction in range of motion. Moderate chronic gonarthritis developed, as seen radiographically. Under the limitation of this single case, temporary trans-articular plating may be considered as useful method for the treatment of long-standing, severely displaced stifle joint luxations in cats.

Abstract A 5-year-old 38 kg entire male German Shepherd dog was referred for persistent non-weight bearing left thoracic limb lameness 5 weeks following failed triceps tendon repair. Physical exam revealed complete incompetence of the triceps mechanism with a large palpable defect proximal to the olecranon and when the shoulder was fixed in extension, the elbow could be fully flexed. A purulent draining tract was present on the caudolateral aspect of the distal brachium. Staged tendon repair was delayed until resolution of infection to allow for improved healing. Culture following surgical exploration of the traumatized area with resection of sinus tract and interposed fibro-granulomatous tissue yielded no growth. Definitive triceps brachii tendon repair was augmented with an autogenous thoracolumbar fascia onlay graft. Postoperatively, the repair was protected with a spica splint and the left thoracic limb immobilized with the elbow maintained in an extended position for 6 weeks. Re-evaluation 7 months later revealed the patient to be free of lameness. Disruption of the triceps brachii tendon is a rarely reported tendon injury with chronic disruption of triceps tendon associated with a guarded prognosis. To the authors knowledge, successful surgical repair of tendinous injury incorporating the use of an autogenous thoracolumbar fascia onlay graft has not previously been described.

Abstract The objective of this case series was to report the surgical technique, complications, and long-term outcome of feline talocalcaneal luxation stabilized with a dorsally applied two-hole, 1.0 mm compression plate. It is a retrospective study of four cats that underwent surgical stabilization of talocalcaneal luxation with a dorsally applied two-hole, 1.0 mm compression plate between 2013 and 2019. Medical history and diagnostic imaging (radiographs ± computed tomography scans) were reviewed. The owners of three of the four cats were contacted with a follow-up questionnaire based on the Feline Musculoskeletal Pain Index to assess long-term outcome. No intraoperative or postoperative complications were encountered. All three owner questionnaires were returned and Feline Musculoskeletal Pain Index scores of 0, 1, and 4 were recorded out of a maximum score of 83 (normal cat range is −18 to 4; cats with degenerative joint disease range from 11 to 66). Quality of life was rated by the owners as excellent (⅔) or good (⅓). All cats returned to full activity. Stabilization of feline talocalcaneal luxation with a dorsally applied two-hole, 1.0 mm compression plate was technically straightforward, easily accessible, and a relatively low-cost treatment option which carries a low risk of complications and an excellent prognosis.

Abstract In this case report, we describe an alternative surgical procedure to treat proximal radius and ulnar nonunion in a toy breed dog. A 14-month-old, Maltese cross-breed dog was referred after previous treatment with external and internal fixation had failed, resulting in a nonunion of a fracture of the proximal radius and ulna with the proximal radius fragment too small and friable to be used for fixation. A craniomedial approach was made to debride the radius nonunion site and a second approach to the lateral aspect of the ulna was made. The fracture was realigned and a titanium locking plate was applied in bridging fashion, fixed to the proximal ulnar fragment with three locking screws in the most proximal plate holes, a fourth screw was inserted in the mid-shaft of the distal ulnar fragment and three locking screws were inserted in the distal most holes of the plate through the distal ulna to engage the distal radial fragment. A recombinant bone morphogenetic protein 2 graft was inserted into the radius and ulna fracture sites. The dog had a successful clinical and radiographic outcome with bridging of the defect 4 weeks postoperatively and complete callus formation 8 weeks postoperatively. Implants have undergone dynamization and then removal. Use of a locking plate as an internal fixator achieving fixation of the proximal ulna and distal radius can be considered an option for the treatment of proximal radioulnar nonunions with a small proximal radial fragment.

Abstract Objectives This work sought to determine the prognosis for dogs for return to athletic function in canine agility competitions after digit amputation. Materials and Methods Data were collected using an Internet-based survey of owners of agility dogs with digit disorders that required amputation. Signalment and physical characteristics were compared between dogs with traumatic and nontraumatic disorders. Athletic performance before and after amputation was assessed subjectively by owner opinion and objectively for eight dogs using competition performance records. Results Problems leading to digit amputation in 46 dogs included acute or chronic traumatic lesions (30 dogs), infection (7 dogs), neoplasia (7 dogs), and cystic lesions (2 dogs). There were no differences in signalment or physical characteristics between dogs with traumatic and nontraumatic disorders. Of the 46 dogs, 39 (84.7%) had returned to agility at the time of the survey and 94.6% of the owners (37/39) were satisfied with performance after amputation. No dog failed to return to agility as a result of the digit disorder or amputation. There was no difference in mean competition speed before and after amputation. Clinical Significance Most agility dogs undergoing digit amputation perform satisfactorily after surgery, although modifications to performance criteria may be appropriate for some.

Abstract Introduction Visual gait analysis is prone to subjectivity, but objective analysis systems are not widely available to clinicians. Simple video analysis using high-definition recordings might enable identification of temporal or spatial variations that could permit objective and repeatable assessments of lameness in general practice. Methods Cohorts of normal and mildly to moderately lame dogs were filmed using a standardized protocol. Using freely available software, measurements of stance, swing and stride time were obtained, along with measurements of pelvic, shoulder, and head height for each limb. Symmetry ratios were calculated, and distributions of normal and lame dogs compared using Mann–Whitney U test and Kruskal–Wallis test. Results Recordings from 35 normal dogs were assessed along with 30 dogs with grade 1 to 3/5 lameness. While no consistent significant differences in temporal characteristics could be found, head height asymmetry was significantly different between lame and normal dogs (p = 0.003), with pairwise comparison showing this difference was restricted to forelimb-lame dogs (p = 0.03). Conclusion While potentially useful for patient records, use of video recordings at walking speeds for simple spatiotemporal gait analysis does not appear to offer clinically significant advantages over visual gait analysis in a typical clinical population of lame dogs.

Conclusion While potentially useful for patient records, use of video recordings at walking speeds for simple spatiotemporal gait analysis does not appear to offer clinically significant advantages over visual gait analysis in a typical clinical population of lame dogs.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"04 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130163844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
