Objective: To report a case of unilateral lateral coronoid process fragmentation in a dog treated via lateral elbow arthroscopy portals., Animal: A 9-month old male intact English Bulldog., Study Design: Case report., Methods: The dog presented with a history of intermittent right thoracic limb lameness. Orthopedic examination on presentation was unremarkable. Computed tomography of the right thoracic limb was pursued and revealed a mineralized focus along the lateral margin of the lateral coronoid process as well as sclerosis of the medial coronoid process and subtrochlear region of the ulna. Elbow arthroscopy was performed via a lateral approach and revealed chondromalacia of the entire lateral coronoid process. Abrasion arthroplasty of the lateral coronoid process was performed., Results: Complete resolution of the lameness was achieved within two weeks of surgery. At 6 weeks postoperatively, the dog remained sound and a gradual return to normal activity was recommended. At the final follow up assessment, 5 months after surgery, no abnormalities were found on orthopedic examination and the owners reported excellent limb function with no observable lameness., Conclusion: Lateral coronoid disease can occur as a rare component of elbow dysplasia in dogs. Abrasion arthroplasty via lateral arthroscopic portals may have resulted in a successful outcome in this case and may form an effective treatment option for lateral coronoid disease in dogs., (© 2024 The Authors.

Objective: To evaluate the usefulness of a high-fidelity model for teaching ovariohysterectomy (OHE) to veterinary students., Study Design: Longitudinal survey., Sample Population: Clinicians with ≥2 years postgraduate experience in small animal surgery and a sophomore veterinary student population at 1 institution., Methods: Twelve clinicians evaluated the high-fidelity model for realism. Questionnaires were distributed to sophomore veterinary students prior to and after OHE training on the high-fidelity model (SynDaver Surgical Canine) and after performing OHE as primary surgeon with a live dog. Time for students to perform OHE (identify the first ovarian pedicle to transecting the uterine body) and number of technical errors (visceral injury, hemorrhage, loose ligatures) were compared between the model and live dog groups., Results: Evaluators rated the high-fidelity model as moderate-to-highly realistic. Students' confidence improved after practicing on the model in all critical steps and additionally improved after performing an OHE on a live dog. Time to complete the OHE on the model (mean ± SD,73.4 ± 27.1 minutes) and live dogs (83.0 ± 24.7 minutes) did not differ (P = .20). Frequency of hemorrhagic events (P = .77) and accidental visceral injury (P = .30) did not differ between the model and live dogs. However, fewer loose ligatures were placed in live dogs (23/64) compared with the model (22/37; P = .02)., Conclusion: The high-fidelity model improved the confidence of sophomore students. The duration of OHE did not differ between the model and live dogs., Clinical Impact: The high-fidelity model is valuable for improving confidence in veterinary students prior to live-dog OHE., (© 2019 The American College of Veterinary Surgeons.)

Objective: To assess iatrogenic articular cartilage injury (IACI) resulting from arthroscopy versus medial parapatellar mini-arthrotomy of the stifle., Study Design: Paired comparison of canine cadaver stifles treated with arthroscopy or mini-arthrotomy ANIMALS: Paired canine stifles from 14 cadavers (≥20 kg)., Methods: Stifles (N = 28) were assigned to arthroscopy or arthrotomy. Full stifle joint exploration and meniscal probing were performed. Joints were disarticulated and India ink assay performed. IACI was defined as sharply delineated lesions with India ink uptake. Incidence, number, and lesion area in defects articular cartilage, incision length, surgery duration, and joint structures visualized were recorded., Results: Arthroscopy resulted in greater IACI than mini-arthrotomy, including incidence of IACI (arthroscopy: 13 stifles, mini-arthrotomy: 4 stifles; P = .009), number of IACI per stifle (arthroscopy: 3.4 ± 2.90, mini-arthrotomy: 0.9 ± 1.96; P = .04), and IACI area (arthroscopy: 5.9 ± 7.58 mm 2 , mini-arthrotomy: 1.7 ± 4.50 mm 2 ; P = .003). Incision length was shorter with arthroscopy (1.0 ± 0.38 cm) versus mini-arthrotomy (5.3 ± 0.61 cm; P < .0001). Surgical duration was not significantly different between groups (arthroscopy: 12.5 ± 3.49 minutes, mini-arthrotomy: 11.05 ± 1.60 minutes; P = .21). Visualization of articular structures was incomplete in 14/14 mini-arthrotomy stifles and 1/14 arthroscopy stifles (P < .001)., Conclusion: Incidence, number, and area of IACI were greater in the arthroscopy group versus the mini-arthrotomy group. Mini-arthrotomy resulted in a longer incision and incomplete joint visualization. Methods of preventing IACI and clinical significance of IACI warrant further investigation., (© 2017 The American College of Veterinary Surgeons.)
