Abstract This study describes the surgical management of a traumatic scapular avulsion including complications and clinical outcome in a 3-year-old Maine Coon cat. Traumatic scapular avulsion was diagnosed clinically and confirmed on a computed tomography scan, alongside severe scapula displacement. The scapula was stabilized surgically by the placement of two circumcostal sutures, through paired bone tunnels drilled both cranial and caudal to the base of the scapular spine, and two sutures passing through bone tunnels in the dorsal border of the scapula bone secured to the serratus ventralis muscle. The cat was able to bear weight on the affected limb within 48 hours of surgery; however, limb function subsequently deteriorated at home. Revision surgery was required 14 days postoperatively to replace failed polydioxanone suture with ultra-high molecular weight polyethylene suture (Fiberwire). Following revision surgery, the cat had a very acceptable functional outcome, with scapular stability and only intermittent lameness/stiffness noted in the medium-term follow-up. The present case report demonstrates that the described modified surgical technique may be used successfully in the treatment of scapular avulsion in cats and restores acceptable function to the affected limb.

Abstract Objective The aim of this study was to describe the successful surgical treatment of a complicated mandibular fracture with a 3.5 mm string-of-pearls (SOP) locking plate in a 5-month-old Appaloosa filly presenting with neurological signs. Study Design This is a case report. Results The neurological signs were due to severe head trauma and stabilized with medical treatment. Financial concerns initially prevented advanced imaging; radiographs identified a mandibular symphysis fracture, a fracture of the left vertical ramus that originated at the junction between the horizontal and vertical ramus and extended toward the coronoid process and rostral maxillary fractures. Following intra-dental wiring of the symphysis fracture, a lateral malocclusion developed. Computed tomography additionally identified fractures of the right wing of the basisphenoid bone, right zygomatic arch, left paracondylar process and the lateral body of the mandible. The vertical ramus fracture was repaired utilizing a 20-hole 3.5 mm SOP plate contoured to the ventral aspect of the angle of the mandible. A scaled (1:4) three-dimensional printed model aided pre- and intra-operative surgical planning. The filly was comfortable and eating well at the 4-week recheck. Radiographs showed good callus formation at the maxilla, healing of the mandibular symphysis and ramus. Just prior to the 10-week recheck, the filly suffered severe enterocolitis and was euthanatized. Conclusion The locking function of the SOP plate provided adequate stability for the fracture to heal without the expense of locking screws. The three-dimensional printed model aided in navigation of the complex fracture without the availability of fluoroscopy.
摘要目的描述3.5 mm珍珠串(SOP)锁定钢板成功治疗5月龄阿帕卢萨母马出现神经系统症状的复杂下颌骨骨折。研究设计这是一份病例报告。结果患者的神经症状多为严重颅脑外伤所致，经药物治疗后病情稳定。最初，资金问题阻碍了高级成像;x线片确认为下颌骨联合骨折，左侧垂直支骨折，起源于水平支和垂直支之间的连接处，并向冠突和上颌吻侧骨折延伸。在牙内连接联合骨折后，出现了侧错牙合。计算机断层扫描还发现了基突骨右翼、右颧弓、左髁旁突和下颌骨外侧体的骨折。垂直支骨折采用20孔3.5 mm SOP钢板进行修复，钢板轮廓为下颌骨的腹侧角。一个比例(1:4)的三维打印模型辅助术前和术中手术计划。在4周的复查中，母马感觉舒适，饮食状况良好。x线片显示上颌骨骨痂形成良好，下颌联合和支愈合。就在为期10周的复查之前，这匹小马患上了严重的小肠结肠炎，并被安乐死。结论SOP钢板的锁定功能为骨折愈合提供了足够的稳定性，无需使用锁定螺钉。三维打印模型在没有透视的情况下有助于复杂骨折的导航。

Abstract Objective Osteoarthritis is a common cause of pain and dysfunction in dogs. Intra-articular (IA) corticosteroids have been used to treat human and animal osteoarthritis; however, their systemic effects have not been well documented in dogs. Therefore, our objective is to determine if a single IA triamcinolone acetonide (TA) injection, at two different doses, suppresses the hypothalamic–pituitary–adrenal axis, induces alkaline phosphatase (ALP), or causes other clinicopathological abnormalities in dogs. Study Design Six healthy female intact adult mongrel dogs from a research colony. For phase one, dogs were randomly assigned to injection of 0.25 mg/kg TA into the right (n = 3) or left (n = 3) stifle. Haematology, liver-related biochemistry and adrenocorticotropic hormone stimulation tests were conducted the day prior to injection and repeated on days 1, 3 and 7, and then weekly after injection until values normalized. Following a 2-week washout period, 0.5 mg/kg TA was injected into the contralateral stifle (phase two), and laboratory testing mimicked phase one. Results Mild, transient adrenocortical suppression occurred in both phases, beginning on day 1 and resolving by days 3 and 7 in phases one and two respectively. However, post-adrenocorticotropic hormone stimulation cortisol levels were never outside the normal range for either phase. Alkaline phosphatase activity increased on day 3 in phase two but remained within normal limits. Mild stress leukograms occurred on day 1 in both phases. No clinical abnormalities were noted throughout the study. Conclusion Systemic adverse effects following IA TA stifle injections at 0.25 mg/kg and 0.5mg/kg are unlikely.

Abstract Objective The aim of this study was to report the successful revision of a loose perforated press-fit cup by exchange with a porous-coated press-fit cup while maintaining the original locking stem and head–neck unit. Methods Cup revision was performed in a dog with a loose acetabular cup that had undergone total hip replacement with a perforated press-fit cup and locking stem 29 months previously. The original locking stem was well integrated. A single session cup exchange was performed by implantation of a 28-mm porous-coated press-fit cup with 16 mm internal diameter to allow the original locking stem and head–neck unit to be preserved. Results Revision total hip arthroplasty by cup exchange resulted in excellent functional outcome with long-term follow-up 18 months postoperatively. There were no intraoperative or postoperative complications. Conclusion A loose perforated press-fit cup was successfully revised with a porous press-fit cup while allowing preservation of the initial locking stem and head–neck unit.

Abstract Background Occipitoatlantoaxial malformation (OAAM) is reported rarely in dogs and few treatment options are described. The congenital condition is thought to be associated with a proatlas re-segmentation failure resulting in malformation and malalignment of the craniovertebral junction which can result in C1 to 5 myelopathic signs. Methods Customized three-dimensional printed locking plate with trajectory screw implantation points for the stabilization of the atlantoaxial joint in a dog with OAAM. The dog was evaluated at time points 0, 2, 6 and 9 months to determine clinical outcome, degree of fusion, implant positioning and subsidence. Results New bone formation was noted 9 months after surgery, but complete fusion remained absent, although no implant failure occurred. Clinically, the dog made a good recovery and was able to exercise normally 9 months after surgery. The only residual deficit was a subtle left-sided cervical torticollis. Clinical Significance This report illustrates a management option and outcome of a dog treated with OAAM. Collaboration between clinicians and engineers provides a new dimension of care for patients with vertebral malformations.

Abstract Objective The aim of this study was to describe the clinical presentation, advanced imaging findings and outcomes of arthroscopic treatment of a bacterial septic shoulder arthritis caused by the penetration of a migrating plant awn in a dog. Case Report A 10-month-old, 11 kg, sexually intact male Cocker Spaniel was diagnosed with septic arthritis of the right scapulohumeral joint. Computed tomography revealed marked articular effusion and thickening of the capsule of the right shoulder joint. Ultrasound of the shoulder identified a bilinear hyperechoic structure located within the joint consistent with a plant (grass) awn. Arthroscopy was used for foreign body removal. Antibiotic treatment was prescribed according to bacteriologic sensitivity tests. Treatment was successful: the dog completely recovered and under high levels of activity showed neither clinical signs nor recurrence of lameness on follow-up at 6 and 24 weeks after surgery. Conclusion Migrating plant awn can be the cause of septic arthritis in a dog. The combination of advanced imaging techniques and arthroscopy allowed accurate diagnosis, reduced the risk of surgical complications and shortened recovery time in this patient. Considering the benefits of minimally invasive techniques, arthroscopy represents an excellent option for the treatment of dogs with similar intra-articular foreign bodies.

Abstract Objective This study aimed to analyse the epidemiological data of canine appendicular avulsion fractures from three academic veterinary hospitals in the United States. Study Design A total of 114 avulsion fractures that presented to three study centres (teaching hospitals in New York, California, and Michigan) between 2008 and 2018 were analysed for avulsion type, breed, sex, body weight, age and affected side. Results The mean age for avulsion fractures was 1.6 years (±2.3 standard deviation), and side and sex were comparable (53% females and 54% left sided, only 2% bilateral). Tibial tuberosity fracture was the most common type, comprising 54% of all avulsion fractures, significantly more prevalent in younger and lighter dogs (p < 0.001). There was no significant difference in avulsion type, breed, sex, weight, age and affected side among three study centres (p = 0.66). Conclusion The most common avulsion fractures were tibial tuberosity fractures, which tend to occur in young, small dogs. There is no sex or side predilection for avulsion fractures noted in this study, although the effect of neuter could not be determined. There were no differences in fracture characteristics among the three different geographical locations in the United States.

Abstract This study aimed to describe surgical technique of arthroscopically guided proximal tibial epiphysiodesis screw placement in the treatment of a bilateral partial cranial cruciate ligament (CrCL) rupture in a 5.6-month-old Golden Retriever. A 19-kg, 5.6-month-old female Golden Retriever was diagnosed with bilateral partial CrCL rupture. Proximal tibial epiphysiodesis was performed bilaterally under arthroscopic guidance. Arthroscopic stifle joint inspection was performed bilaterally with a 2.7 mm arthroscope. A medial port at the level of the distal one-third of the patella was used as camera portal. A lateral instrument port was positioned at the level of the distal one-third of the patella. A 3.0 mm diameter headless cannulated self-compressive screw was placed into the centre of the tibial cranial intercondyloid area as parallel as possible to the tibial shaft axis under arthroscopic control. Screw head was buried. Arthroscopic guidance allowed good accuracy in screw placement, specifically in its insertion point. However, the screw orientation was less satisfactory. The tibial plateau angle progressively decreased in both stifles to achieve 15 degrees on the left and 16 degrees on the right at the last follow-up. A varus deformity developed on both stifles. No clinical consequences were observed. Recurrence of right pelvic lameness occurred 1 year postoperatively because of a medial meniscal lesion, which necessitated partial caudal meniscectomy. Arthroscopically guided proximal tibial epiphysiodesis is technically feasible and is a minimally invasive treatment of CrCL injury in a juvenile dog.

Abstract A 9-year-old, intact male, German wirehaired pointer was referred for suspected Achilles tendon rupture 3 weeks after an injury. A three-loop pulley suture pattern combined with a locking loop suture reduced the gap between the tendon ends to 7 mm and a central gastrocnemius turnover aponeurotic flap was used to cover the remaining gap. A type II free-form methyl methacrylate transarticular external skeletal fixator was used to keep the tarsocrural joint in extension until 45 days postoperatively. Short- and long-term clinical and ultrasonographic evaluations showed gradual improvement in weight-bearing and progressive tendon healing. At 6 months after surgery, the dog had normal limb function and had returned to the previous activity level. To the authors' knowledge, this tendon repair technique has been described in humans and in one cat but has not yet been reported in dogs.

To the authors' knowledge, this tendon repair technique has been described in humans and in one cat but has not yet been reported in dogs.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131386706","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}

Abstract This study aimed to assess the long-term outcome and intervertebral fusion following surgical distraction and stabilization using an intervertebral cage and pedicle screw and rod fixation (PSRF) in a dog with severe degenerative lumbosacral stenosis (DLSS).Degenerative lumbosacral stenosis is a common disorder in large breed dogs and has a multifactorial origin. Surgical treatment by dorsal laminectomy and discectomy results in decompression of neural structures, but when distraction–fixation is applied, the ultimate goal is vertebral fusion. A 4-year-old male neutered Leonberger, presented with DLSS and pre-existent chronic discospondylitis, was treated by dorsal laminectomy, partial discectomy, curettage of the end plates, distraction with an intervertebral spacer (SynCage), and PSRF. At 26 months after surgery, the Helsinki pain score and neurological Griffith score were improved; however, the dog passed away shortly thereafter due to an unrelated disorder. The lumbosacral segment became available for computed tomography (CT), micro-CT and histopathology. On CT, bone volume through the largest hole of the cage was 91.0% and for compact bone 76.1%. Micro-CT and histopathology revealed vertebral fusion. Distraction–fixation using an intervertebral spacer and PSRF was well-accepted in this dog with severe DLSS, and the dog had a good clinical outcome with long-term follow-up. CT, micro-CT and histopathology showed evidence of vertebral fusion.
