Patients with a minimum follow-up period of 12 months and complete medical records were included and analyzed for radiographic and clinical outcomes.Results: Thirty THA with SCSL in 23 dogs were included in this study. Complications were observed in seven hips, comprising two minor and five major complications, with two hips experiencing two major complications. Among these seven major complications, six were associated with the femoral implant and one involved cup luxation. Of the 30 THA, 4 were explanted, while 26 remained in place for a median follow-up of 17.5 months (range, 12-38 months).Conclusion: No cases of late aseptic loosening were observed with SCSL. THA using SCSL helps reduce cup-associated complications and is appropriate for THA surgery, and the overall complication rate is comparable with that of other single-implant systems.

Construct stiffness and surface strain, calculated using three-dimensional digital image correlation, were compared across plate length and region of interest (ROI) on the construct.Results: The 12-hole plates (80% plate-bone ratio) had significantly higher construct stiffness than 6-hole, 8-hole, and 10-hole plates and significantly lower plate strain than 6-hole plates at all ROIs. Strain on the bone model was significantly lower in constructs with 10-hole and 12-hole plates than 6-hole plates under both compression and tension bending.Conclusion: Incremental increases in construct stiffness and incremental decreases in plate strain were only identified when comparing 6-hole, 8-hole, and 10-hole plates to 12-hole plates, and 6-hole to 12-hole plates, respectively. Strain on the bone model showed an incremental decrease when comparing 6-hole to 10-hole and 12-hole plates.

This study aims to describe in detail CT and MRI features of gracilis myopathy.Study design: This is a retrospective study. Medical records of dogs with characteristic gait and available pelvic limb MRI or CT, presenting to four referral institutions, were reviewed.Results: Seven cases with MRI (3/7) or CT (4/7) were included, all German Shepherd dogs. MRI findings in all cases included a well-defined, T1-/T2-/proton density-weighted hypointense band along the axial margin of the gracilis muscle, shorter affected muscles, thickening and T2W/STIR hyperintensity with contrast enhancement at the symphyseal tendon, and concurrent focal indentation of the axial border of the gracilis muscle. CT findings included a hyperattenuating band (4/4), single instances of contrast enhancement at the origin of the muscle, thickening of the tendon at the origin and insertion, and concurrent thickening at the musculotendinous muscle.Conclusion: CT and MRI can present advantages in correctly identifying the specific muscles affected within the gracilis-semitendinosus muscle complex. Both modalities can localize anatomically lesions in detail, for instance at the origin or insertion of the muscle, which could present advantages in novel treatment strategies for this condition.","PeriodicalId":51204,"journal":{"name":"Veterinary and Comparative Orthopaedics and Traumatology","volume":" ","pages":"87-95"},"PeriodicalIF":1.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142640265","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}

Surgical planning utilized CAD-based techniques, and 3D-printed guides were created for precise osteotomies and implant placement. Follow-ups included radiographic assessments, re-examinations, and owner-reported outcomes.Results: Four feline cases with distinct shoulder issues were successfully treated using PSG. Postoperative management, radiographic evaluations, and long-term follow-ups revealed positive outcomes in terms of limb function and patient activity. The study demonstrates the potential of PSG in achieving accurate humeroscapular alignment in feline shoulder arthrodesis.Clinical significance: This case series highlights the clinical significance of PSG in enhancing the precision of humeroscapular alignment during feline shoulder arthrodesis.

Signalment, body weight, fracture aetiology, fracture location and configuration, radius diameter, plate-bone ratio, repair method, clinical and radiographic outcomes, complications, and time to last follow-up were recorded.Results: Thirty fractures in 28 dogs were included. Median body weight was 2.4 kg (range 1.3-5.5 kg). The mean length of the proximal segment relative to the total length of the radius was 67% (range 33-93%).

All groups were tested with destructive axial compression with load applied to the femoral head. The stiffness, load, and displacement were evaluated at the failure of Group 1, and the yield load and displacement of Groups 2 and 3.Results: The placement of the three cannulated screws was more demanding than two cannulated screws because of the risk of cortical perforation, especially in the trochanteric fossa area. The smaller the width of the femoral neck, the higher the risk of cortical bone wall perforation. The intact control bones were stiffer (674 N/mm) than both the two-screw repair (90 N/mm) and three-screw repair (120 N/mm) groups (p < 0.05). The failure load was greatest for Group 1 (2692 N). The yield loads for Groups 3 and 2 were 586 and 303 N, respectively.
