Both patients underwent thoracoscopic treatment in which the abscess was opened, debrided, and lavaged with a combination of sharp dissection and use of a vessel-sealing device. One patient required partial conversion from total thoracoscopic treatment to a thoracoscopic-assisted approach due to limited visualization of the caudal mediastinum.Results: Both dogs recovered uneventfully from surgery and were discharged 3 and 4 days postoperatively. Case 1 was re-evaluated with their primary veterinarian 7 days postoperatively and was reported to be doing very well.

Measurements included osteotomy angulation, medial cortical damage, eccentricity distance, postoperative tibial plateau angle, angular and torsional deformities, and surgical time. Data were obtained from specimen photographs and computed tomography images and then compared statistically.Results: The contoured saw guide was related to improvements in bone models, with reduced osteotomy angle of inclination (0.97° vs. 3.4°, p = .038), osteotomy angle of torsion (257 vs. 2573 pixels, p < .001), and medial cortical damage (247 vs. 1866 pixels, p < .001). In cadaveric limbs, the contoured saw guide also demonstrated better performance, with reduced osteotomy angle of inclination (1.2° vs. 4.3°, p = .008) and osteotomy angle of torsion (2054 vs. 5039 pixels, p = .016).Conclusion: Tibial plateau leveling osteotomy performed with the contoured saw guide achieved more precise osteotomy angulation and caused less medial cortical damage than the conventional jig-assisted technique.Clinical significance: The contoured saw guide may enhance osteotomy accuracy and minimize iatrogenic damage caused by the saw during TPLO but in this study it did not shorten surgical time.","PeriodicalId":23667,"journal":{"name":"Veterinary Surgery","volume":" ","pages":"1397-1408"},"PeriodicalIF":1.3,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144020824","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}

Preoperative variables included age, sex, breed, and affected site(s). Surgical variables included types of KCC used, intraoperative complications, and anesthesia related complications. Long-term outcomes were obtained by telephone interviews with the owners, trainers, and/or attending veterinarians.Results: A total of 38 horses had a KCC placed and 34 of 38 horses (89%) were discharged from the hospital and were alive >3 months postoperatively.

Dogs were excluded if overt pathology of the CCL was noted during orthopedic examination and/or surgical evaluation. Correlation of increased radiographic soft tissue opacity with age, breed, weight, duration of clinical signs, presence of stifle osteoarthritis, muscle atrophy, and luxation grade were evaluated.Results: Increased radiographic soft tissue opacity of the stifle was appreciated in 37/57 (65%) stifles. Weight (p = .029) and presence of osteoarthritis (p = .0143) were associated with the presence of increased radiographic soft tissue opacity. For every 1 kg increase in weight there is a 10% increased risk in having this radiographic change. Four of 21 dogs (19%) with long term follow-up were diagnosed with a CCL injury 2, 2.5, 4, and 4.5 years postoperatively.

Intraoperatively, fluoroscopy was used to identify the intercondylar eminence (intended center of rotation), which was marked with a 0.035-inch Kirschner wire. The osteotomy site was dynamically adjusted to maintain a 21 mm radius from the center of rotation before proceeding with the osteotomy. Preoperative radiographic measurements (D1 and D2) were compared to intraoperative fluoroscopic measurements (R1 and R2) to assess reproducibility. Postoperative TPA was measured on routine radiographs.Results: A total of 30 TPLOs were performed. The median postoperative TPA based on fluoroscopic guidance was 3° (range: 0-4°). The median absolute difference between R1 and 21 mm was 0.5 mm (range: 0.0-3.0 mm), while the difference between R2 and 21 mm was 2.5 mm (range: 0.0-4.0 mm). D1 measurements demonstrated greater intraoperative reproducibility than D2.Conclusion: Fluoroscopy-assisted osteotomy placement resulted in precise postoperative TPA alignment with minimal deviation.
