However, the proposed benefits of closed reduction should be applicable to articular fractures if appropriate reduction and implant placement can be achieved. The aim of this study was to retrospectively evaluate a surgical technique for minimally invasive reduction and stabilization of fractures of the humeral condyle by means of intraoperative traction applied to the ulna under fluoroscopic guidance. Nineteen fractures of the humeral condyle in eighteen dogs were reduced by intraoperative osteotaxis applied by traction of the ulna, minimally invasive approach to the epicondyle and fracture stabilization under fluoroscopic guidance. Postoperative reduction was considered good or excellent in most fractures. This technique can be considered as a potential option for the treatment of condylar fractures, allowing for minimally invasive reduction and stabilization, thus avoiding the need for surgical exposure of the elbow joint.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130847065","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}

In dogs, the test consisted in a flexion of a joint to its full range of motion for 1 minute. Eventual increased lameness was then evaluated. The gait was evaluated using a visual analogue scale. An increase in the lameness score compared with the baseline score was considered as a positive result.The method was described for every major joint of the appendicular skeleton and was evaluated in sound and lame dogs. To evaluate the feasibility, the FT was applied for 3 minutes in eight healthy dogs on all joints. On 27 clinically lame dogs, flexion was applied for 1 minute on the joints with a suspected pathology and on their contralateral side used as a control.\u0000 Results The FT was feasible and well tolerated by the sound dogs on all joints and no positive results were recorded. On clinically lame dogs, lameness increased in 81.5% of dogs. These cases were afterwards diagnosed with an orthopaedic-related disorder and then defined as true positives. False negative results occurred in 18.5% of the lameness cases.\u0000 Conclusion The FT is safe and easy to perform. It did not produce any false positive results. False negatives might occur in a minor number of cases, implying that a negative result does not exclude a joint pathology.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128958003","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}

This report describes the clinical, radiological, and surgical treatment of a basilar invagination associated with instability of the atlantoaxial joint due to an incomplete ossification of the atlas in a cat. At presentation, the clinical signs included obtundation and non-ambulatory tetraparesis with postural reaction deficits in hindlimbs and left forelimb. Radiographic examination revealed cranial displacement of the axis with the dens impinging the basioccipital bone, and computed tomography confirmed the impaction of the axis on the atlas due to an incomplete ossification of the left half of the neural arch with the intercentrum. Magnetic resonance imaging confirmed severe spinal cord compression and myelopathy at this level. The cat underwent surgery for atlantoaxial arthrodesis using a ventral approach to C1-C2. Recovery after surgery was uneventful. Follow-up a year after surgery finds the cat free of neurological signs. An incomplete ossification of the atlas can lead to atlantoaxial instability and basilar invagination in the cat. Diagnosis can be made based on its radiological characteristics, the cranial displacement of the odontoid process in contact with the basioccipital bone being its main feature. This case was successfully treated by atlantoaxial arthrodesis.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128785325","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}

This is further complicated by the inherent inaccuracy of free-hand implant positioning procedures. A 6-month-old German Shepherd presented with a 15 × 7.8 × 4.3 mm OCD defect at the lateral femoral condyle. A synthetic patient-specific implant (PSI) was designed, using the contralateral unaffected condyle as a template. Reaming of the implant bed was fully guided using a set of three-dimensional-printed drill guides. The implant, consisting of a titanium base and a polycarbonate urethane bearing surface, was press-fit into place. Temporary meniscal release of the cranial meniscal horn was repaired, followed by routine closure and postoperative care. The combination of PSI and matching drill guides resulted in an accurate restoration of the normal joint surface at the former defect area. At 6-week and 18-month follow-ups, mild joint effusion, unexpected soft tissue mineralization and a small joint mouse were present. No other complications were encountered, and the dog was clinically lameness-free. At 6 weeks and 6 months, computerized gait analysis documented increased loading of the affected limb from 36% preoperatively to 42 and 40%, on follow-up, respectively. Body weight distribution between both hindlimbs was nearly equal at the 6-month control with 1% difference in loading. Osteochondral resurfacing using a PSI appears to be a promising treatment option for large stifle OCD lesions in which other treatment modalities may not be eligible.","PeriodicalId":443672,"journal":{"name":"VCOT Open","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122867290","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}

Bilateral, rostral, mandibular lesions consistent with dentigerous cysts were identified by intraoral radiography and CT. The left cyst was associated with an open, mildly displaced mandibular fracture. Treatment of the cystic lesions consisted of surgical exposure, extraction of embedded teeth, curettage of the cyst lining, and placement of demineralized bone matrix. Reduction and stabilization of the fracture were achieved by interdental wiring combined with an intraoral splint. Follow-up examination and CT imaging were performed at 8, 18, and 85 weeks postoperatively. Complete fracture healing and resolution of both cystic lesions were confirmed at 18 weeks with no recurrence evident at 85 weeks. No complications were encountered. To the authors' knowledge, this is the first case report of a pathologic mandibular fracture secondary to a dentigerous cyst in a dog, documenting the healing of dentigerous cysts via CT with progressive replacement of demineralized bone matrix by new osseous growth.
