In Araos 2024 et al., on helmet CPAP in brachycephalic postoperative dogs, how many dogs were withdrawn due to poor helmet tolerance?
🔍 Key Findings
- CPAP at 5 cmH₂O via helmet significantly improved PaO₂/FiO₂ ratio in the early postoperative period of brachycephalic dogs, supporting enhanced pulmonary oxygen exchange (p = .04).
- CPAP had no significant effect on SpO₂ (p = .9), PaCO₂ (p = .18), or rectal temperature (p = .5).
- Helmet tolerance decreased over time, with 13 dogs withdrawn for intolerance (9 CPAP, 4 control) and 6 dogs withdrawn for airway compromise (5 control, 1 CPAP).
- CPAP group maintained PaO₂/FiO₂ ratios near or above 400 mmHg, while control dogs showed consistently lower values.
- Authors suggest PaO₂/FiO₂ is a more reliable oxygenation measure than SpO₂ for evaluating postoperative lung function.
- The study found no cases of hyperthermia; temperatures normalized over time in both groups.
- Arterial catheterization failed in several dogs, limiting blood gas analysis to a subset of the population.
- Authors recommend further studies focused on BOAS patients and exploring longer-duration CPAP use to assess impact on critical outcomes like tracheostomy rates or hospitalization.

In Maeta 2022 et al., on total cystectomy in cats, how was urinary incontinence managed postoperatively?
🔍 Key Findings
- First reported case of total cystectomy and bilateral cutaneous ureterostomy in a cat using a modified Toyoda technique.
- Histologically complete tumor resection was achieved, with tumor-free ureter and urethral margins >20 mm.
- The modified Toyoda technique involved shaping the ureter into a fish-mouth aperture and anastomosing it to a rectangular skin defect for stomal formation.
- Incontinence was managed using a diaper changed every 6–8 hours, with no dermatological complications.
- Obstruction of the right ureter occurred 14 months post-op, associated with a subcutaneous nodule at the anastomosis site.
- Despite incontinence, owner satisfaction and perceived quality of life were high, with the cat living ~16 months post-op.
- The stents were removed on days 7 (left) and 28 (right) postoperatively, with initial patency maintained until 14 months.
- This surgical approach may offer palliative or curative benefit for feline trigonal TCC where partial cystectomy is not feasible.

In McCagherty 2025 et al., on WID detection accuracy, what was a notable limitation of using PCR in this study?
🔍 Key Findings
- Bacterial fluorescence was detected in all wounds (17 dogs, 4 cats) using the point-of-care wound imaging device (WID).
- The WID confirmed the presence of clinically relevant wound infection in all evaluated cases at the time of imaging.
- No significant difference was found in bacterial yield or burden between image-guided and non-guided swabs (QBC and PCR; p > 0.05).
- The WID helped guide wound debridement in some cases by localizing areas of fluorescence, especially in necrotic tissue.
- Most infections were polymicrobial and dominated by anaerobes, highlighting the need for anaerobic culture inclusion.
- PCR analysis showed low bacterial DNA yields, often complicated by host DNA contamination, limiting its utility.
- The study did not evaluate sensitivity/specificity of WID, as only fluorescence-positive wounds were included.
- Clinical utility of WID lies in immediate visual confirmation of infection, supporting timely antimicrobial treatment decisions.

In Gollnick 2024 et al., on TCTF risk with Arthrex STS in TPLO, what was the TCTF rate for STS screws placed distal to the osteotomy?
🔍 Key Findings
- 42% of dogs (33/78) treated with Arthrex 3.5 mm STS during TPLO developed radiographic TCTF
- TCTFs occurred exclusively distal to the osteotomy
- 14% of screws (36/250) distal to the osteotomy were associated with TCTFs
- 6% of dogs with TCTFs developed major complications (e.g., complete tibial fracture requiring surgical revision)
- Angulation of cortical STS screws, especially in the distal plate holes, was a key contributor to complications
- Locking screws were also involved, but cortical screws angled improperly were overrepresented in serious outcomes
- Revision recommendations included preemptive fixation for large TCTFs or angulated screw placements
- Use of non-self-tapping screws (NSTS) previously showed a <1% TCTF rate, supporting higher risk with STS

In Karlin 2026 et al., on acetabular cup radiography, what was the primary reason proposed for poor accuracy in open-face version measurement using the CPAD?
🔍 Key Findings
- CPAD accurately measured angle of lateral opening (ALO) on sagittal radiographs with near-perfect agreement (Lin’s Rc = 0.994) compared with known angles.
- No significant difference between measured and true ALO values was detected (p = 0.655), supporting accuracy of the device for this parameter.
- Mean ALO measurement error was only 0.14° ± 1.18°, indicating high precision of the CPAD method.
- Open-face version measurements were significantly inaccurate compared with known values (p < 0.0001).
- Mean error in version measurement was 9.5° ± 6.31°, showing only moderate agreement (Rc = 0.424).
- Measurement error in version likely resulted from radiographic superimposition of the V-axis bar with the cup edge, making bar endpoints difficult to identify.
- CPAD accuracy for ALO (~1.18°) is nearly five times better than previous radiographic techniques, which typically achieve ~5° accuracy.
- Intraoperative fluoroscopic use of CPAD may allow real-time adjustment of cup orientation, potentially reducing luxation risk after canine THA.

In Guénégo 2025 et al., on AMA-based CCWO, which combination was key to minimizing SSIs in AMA-based CCWO?
🔍 Key Findings
- AMA-based CCWO realigned the anatomical and mechanical axes in 82% of dogs >50 kg, with postoperative AMA angle of 0° in most cases.
- Surgical site infection (SSI) rate was only 0.5%, markedly lower than TPLO-reported rates in similar populations (up to 37.5%).
- All osteotomies achieved Grade 4 healing by 8 weeks, with no implant failures.
- AMA-based planning based on preoperative AMA and TPA allowed for better correction of proximal tibial angulation compared to TPLO in large dogs.
- Use of a double locking plate (DLP) fixation and Robert Jones bandage (RJB) contributed to improved mechanical stability and infection prevention.
- Dogs with AMA angle >3.4° (hyper-CCAPT) were 38% of the cohort, supporting AMA as a critical metric in planning.
- Postoperative alignment of the AA and MA was more consistently achieved when preoperative AMA was >2.4°, confirming suitability of AMA-based CCWO for severe angulation.
- Most infections in TPLOs occur within 15 days, but RJB plus antibiotics in this study appeared protective, suggesting benefit for early-phase SSI prevention.

In Kwok 2023 et al. on BFX lateral bolt THR in dogs,what factor was most associated with postoperative femoral fractures?
🔍 Key Findings
- 97.4% of dogs returned to normal function after total hip replacement using the BFX lateral bolt.
- Mean femoral stem subsidence was 1.22 mm, with most occurring in the first month and minimal thereafter.
- Postoperative complication rate was 13.6%, with 9.2% major and 4.4% minor complications.
- Femoral fractures (3.6%) and coxofemoral luxations (3.6%) were the most common major complications.
- Increased age and higher stem size were risk factors for postoperative femoral fractures; CFI >2.0 was also associated.
- Medial calcar fractures were avoided, and fractures occurred distal to stem ingrowth zone, simplifying repairs.
- Three cases underwent prophylactic plating, all with excellent outcomes and no complications.
- Explant rate was 2.6% (5/195), with most failures involving acetabular cup rather than femoral stem.
