Nondestructive dynamic tests evaluated stiffness over time in torsion and bending. Torsion destructive tests provided maximum torque and rotation values, whereas the four-point bending tests provided the yield load, maximum bending load, and maximum displacement.Results: The INT group showed higher torsional stiffness and maximum torque but similar bending stiffness, torsional strength, and bending strength in one or more groups. LP and TIF 2 exhibited the highest similarity frequencies among the treatment groups, whereas the TIF 1 group displayed lower stiffness and strength for most of the evaluated parameters.Conclusion: Similar results for LP and TIF-2 groups suggest the biomechanical equivalence of these methods for tibiotarsal osteosynthesis in adult hens.","PeriodicalId":51204,"journal":{"name":"Veterinary and Comparative Orthopaedics and Traumatology","volume":" ","pages":"145-152"},"PeriodicalIF":1.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142640266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten metacarpophalangeal joints were collected from five adult Thoroughbred horses, euthanatized for reasons unrelated to orthopaedic disease. Each pair of metacarpophalangeal joints was randomly instrumented with either a 1.7-mm SSC or a NMPC. Each construct was tested in cyclic loading followed by a single cycle to failure in axial compression. Displacement at a target load of 200 N over 500 cycles at 1 Hz was recorded prior to single-cycle to failure testing.In cyclic testing, the overall movement of the NMPC constructs was more than that of the SSC constructs (p < 0.0001). In single-cycle testing, the maximum load achieved at failure in the SSC constructs was higher compared to the NMPC constructs (p = 0.0002).The results of this study do not support the use of a NMPC as a palmar/plantar tension band for metacarpophalangeal joint arthrodesis in horses suffering from a suspensory breakdown injury, because the stability of the SSC constructs outweighs the potential benefits and ease of application of the NMPC.

The objective of this review is to discuss the physical principles of ultrasound elastography and its applications in the musculoskeletal system of veterinary medicine. This bibliographic review compiles relevant studies exploring elastography's physical basis, its technological development, and its clinical applications in veterinary contexts. Elastography complements B-mode ultrasound by assessing tissue stiffness, offering unique diagnostic insights beyond acoustic impedance and flow properties. Studies have demonstrated the potential of elastography in evaluating tendon injuries, muscle disorders, and bone healing, with promising results in dogs, horses and experimental models like sheep. Techniques such as compression elastography and shear wave elastography provide qualitative and quantitative data, enhancing the assessment of pathological changes. Shear wave elastography enables precise measurements of tissue elasticity, aiding the diagnosis, monitoring of healing and evaluation of therapeutic interventions. Despite technical challenges, elastography is a valuable tool that can optimize musculoskeletal diagnostics and treatment planning. Its expanding use in veterinary medicine underscores its clinical relevance and potential for widespread adoption as a complementary imaging modality.","PeriodicalId":51204,"journal":{"name":"Veterinary and Comparative Orthopaedics and Traumatology","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144042756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
