RESUMEN
OBJECTIVE: To assess clinical outcomes of lung lobectomies in dogs and cats using either self-ligating loops (SLLs) or thoracoabdominal (TA) staplers, aiming to inform sample size calculations for future superiority trials. STUDY DESIGN: Retrospective study. ANIMALS: A total of 72 dogs and 15 cats. METHODS: Records from January 2003 to October 2023 at a single institution were reviewed. Cases with lung lobectomy performed via TA stapler or SLL with a minimum 14-day postoperative follow-up were included. Pre-, intra-, and postoperative data were collected, with outcomes of interest including the frequency of intra- and postoperative complications. Outcome comparisons between techniques were performed to inform sample size calculations. RESULTS: A total of 101 lung lobectomies were performed. The TA stapler was used in 83 (82.2%) and the SLL in 18 (17.8%) lung lobectomies. Intraoperative complications were identified in 14/101 lung lobectomies (13.9%), including intraoperative hemorrhage in 12/101 lobectomies (11.8%) and air leakage in 2/101 lobectomies (1.9%). Postoperative complications were identified in 12/87 cases (13.8%), including 4 (4.6%) catastrophic complications and 5 (5.8%) major complications. All intra- and postoperative complications occurred in cases having undergone stapled lung lobectomy; however, no differences were identified between surgical technique and either intraoperative (p = .069) or postoperative complications (p = .112). A sample size of 103 lobectomies per technique group would be required for appropriate evaluation. CONCLUSION: Lung lobectomy using either surgical technique provided a good short-term outcome in this population. CLINICAL SIGNIFICANCE: Self-ligating loop lung lobectomy provided a comparable alternative to stapled lung lobectomy. Further studies are needed to assess technique superiority.
RESUMEN
OBJECTIVE: To describe the dome trochleoplasty procedure and report the short-term outcomes and complications associated with a novel technique to correct patellar luxation and patella alta. ANIMALS: 13 dogs (16 stifle joints) diagnosed with medial patellar luxation with concurrent patella alta in dogs > 20 kg. CLINICAL PRESENTATION: Medical records of dogs weighing > 20 kg that underwent a dome trochleoplasty for correction of a medial luxating patella were prospectively evaluated. The procedure described involves an osteotomy of the femoral trochlea, which is then translated and/or rotated to correct patellar luxation. Clinical results were assessed using subjective lameness scoring, radiographic evaluation, and the Canine Brief Pain Inventory (CBPI) tool. RESULTS: 16 stifle joints were included in this study. The overall complication rate was 50%. Major complications occurred in 43.8% of stifle joints due to pin migration and recurrent luxation of the patella. One dog experienced a catastrophic complication 4 months postoperatively. Uncomplicated osteotomy healing was present in 94% of dogs. The median initial lameness score was 2 (mean, 1.81; range, 0 to 4) and at the final recheck was 0 (mean, 0.31; range, 0 to 2). The CBPI scores were available for 50% of stifle joints. The median initial CBPI score was 45.5 (mean, 48.8; range, 32 to 74) and at the final recheck was 17.5 (mean, 20.5; range, 0 to 43). CLINICAL RELEVANCE: The dome trochleoplasty procedure offers an alternative technique for surgical correction of patellar luxation secondary to patella alta in large-breed dogs, but due to its higher complication and reluxation rates, it should be used cautiously and probably in combination with other corrective procedures, such as tibial tuberosity transposition, soft tissue imbrication, and/or soft tissue release rather than as a stand-alone procedure.

OBJECTIVE: To evaluate the clinical outcomes associated with the Biomedtrix Centerline canine cementless total hip arthroplasty implant (C-THA). ANIMALS: 17 dogs (20 hips) surgically implanted with C-THA to treat coxofemoral pathology. CLINICAL PRESENTATION AND PROCEDURES: Dogs with C-THA (2015 through 2020) with follow-up of ≥ 6 months were evaluated. Data included signalment, complications, management of complications, radiographs (bone implant interface), and clinical outcomes. Outcomes were assessed radiographically and subjectively via surgeon orthopedic examinations. RESULTS: 15 of 20 (75%) with long term radiographic follow-up had an excellent outcome. 5 hips (25%) had postoperative complications: femoral neck fracture (n = 1; 5%), aseptic loosening (2; 10%), and septic loosening (2; 10%). CLINICAL RELEVANCE: C-THA can restore function in dogs with coxofemoral pathology. This novel procedure showed outcomes comparable to initial reports of other traditional THA implants (cemented, cementless, and hybrid) but complications occurred at a higher rate than recent outcomes of other long-standing THA procedures. Increased case numbers and surgeon experience with this novel implant system may eventually yield results comparable to other accepted THA systems.
