🔍 Key Findings

• Cystoscopic-guided laser ablation (CLA) was associated with significantly fewer minor complications (13%) than neoureterostomy (100%) (P < .01)
• CLA resulted in significantly fewer recurrences of incontinence compared to neoureterostomy (0/7 vs 5/12; P < .05)
• 80% of dogs achieved continence within 1 month postoperatively, with a median continence score of 10
• Long-term continence was achieved in 88% of dogs, with or without adjunctive treatment, over a median of 66 months
• Major complications occurred in only 8% of dogs, and all were successfully managed with surgical revision
• Persistent ureteral remnants were seen only in neoureterostomy dogs, potentially contributing to incontinence recurrence
• All dogs with incontinence recurrence responded to medical treatment, while only 1/5 with persistent incontinence after surgery did
• CLA is recommended over open surgery for iEU correction, due to lower complication and recurrence rates

🔍 Key Findings

• Dogs with MPL had significantly shallower femoral trochlear grooves compared to controls, based on CT-measured femoral trochlear groove angle (FTGA).
• FTGA >134° in small breeds (SB) and >128° in medium/large breeds (MLB) were associated with MPL and can serve as surgical thresholds for considering trochleoplasty.
• FTA and FTRIA measurements were less reliable, showing lower sensitivity/specificity than FTGA.
• Inter-rater reliability for FTGA was excellent (ICC > 0.9), supporting its use in clinical decision-making.
• FTGA differed significantly between SB and MLB dogs, suggesting anatomical variation influences MPL predisposition.
• Dogs with MPL but with FTGA below threshold may not benefit from trochleoplasty, supporting individualized surgical planning.
• CT provides more precise and reproducible evaluation of trochlear morphology than radiography or ultrasound.
• The study introduces a CT protocol using P25 and P50 reference points for consistent FTGA measurement.

🔍 Key Findings

• Hybrid THR in cats showed no major complications across 17 hips in 15 cats, including 2 bilateral cases.
• Postoperative radiographs confirmed stable implant positioning with no loosening, migration, or dislocation in follow-up imaging.
• Mean owner satisfaction was high, with a mean short-form feline musculoskeletal pain index (sf-FMPI) score of 2/36 at a mean follow-up of 438 days.
• SCFE (slipped capital femoral epiphysis) was the most common indication, seen in 13/17 hips.
• Partial tenotomy of rectus femoris origin resolved intraoperative medial patella luxation in 3 cases—no cats required surgical correction later.
• A micro BFX cup allowed for increased acetabular offset, possibly reducing luxation risk even when using a +0 femoral head offset.
• Hybrid THR was successfully used as a revision for failed CFX THR due to recurrent luxation—implants remained stable post-revision.
• Use of oversized cups (12 mm) with shallow seating or medial breach still resulted in stable outcomes, suggesting good implant fixation even with reduced bone stock.

🔍 Key Findings

• Ex vivo study using 24 canine cadaver pelves to test screw thread direction in SI luxation.
• Four groups: RhRSI, RhLSI, LhRSI, LhLSI.
• Right-handed screws on right side (RhRSI) had 313% higher torque and 274% higher load vs left side (p < .01).
• Left-handed screws on left side (LhLSI) had 198% higher torque and 195% higher load vs right side (p < .03).
• All failures occurred due to rotation, with no screw breakage or fractures.
• Body weight and moment arm were similar across groups.
• Clinical implication: Use of screw matching handedness to luxation side improves stability.

🔍 Key Findings

• Both patient-specific and universal guides yielded correction errors <2°, with no statistically significant difference in accuracy.
• Universal guide corrected aLDFA up to 24° and AA up to 20°, addressing multiplanar deformities effectively.
• Patient-specific guides allowed for preoperative simulation, providing more stable pin placement and potentially aiding less-experienced surgeons.
• Universal guide eliminated the need for CT-based customization, reducing time and cost.
• Cadaver and bone model trials showed consistent accuracy, validating both methods in vitro and ex vivo.
• No significant differences in outcome when correcting uniplanar (aLDFA) vs biplanar (aLDFA + AA) deformities.
• Universal guide's fixed size presented limitations in small dogs, potentially requiring multiple size options.
• Universal guide showed potential for standard use, offering repeatable outcomes with minimal prep despite needing precise intraoperative placement.

🔍 Key Findings

Study Design: Case series of 8 dogs with confirmed or suspected PJI after total hip replacement (THR)
Dogs were categorized into:

• Curative intent (CI) group (n=5): short-duration infections, implant retention attempted
• Non-curative intent (NCI) group (n=3): chronic infections, implants scheduled for removal or revision

Success Rate: 7 of 8 dogs had infection resolution, including 4 of 5 in the CI group
Sampling sensitivity:

• Arthroscopic culture success was 80% in the CI group but only 33% in the NCI group
• All explanted implants from NCI group yielded positive cultures

Common isolates: Staphylococcus pseudointermedius (including MRSP), S. epidermidis, Stenotrophomonas maltophilia, and E. coli
Ancillary treatments included:

• Partial synovectomy, high-volume lavage (5–10 L), biofilm-depleting lavage, and/or amikacin-impregnated calcium sulfate beads

Mean follow-up: >1 year (mean 812 days); no signs of recurrence in successfully treated cases
Conclusions: Arthroscopic management of THR infections is feasible and effective in appropriately selected dogs. Success aligns with human literature when infection type is favorable (Type 1, 3, 4). Sensitivity of arthroscopic culture is higher in early/acute infections.

🔍 Key Findings

• Mitral valve plasty (MVP) in dogs with MMVD significantly reduced regurgitant volume and fraction, and normalized LA:Ao ratio, indicating reversal of volume overload.
• MVP altered mitral valve geometry, with reduced annular dimensions and increased coaptation length, enhancing valve competence.
• Postoperative LA:Ao ratio dropped from 2.2 to 1.2, consistent with improved left atrial pressure and size.
• Forward stroke volume index and cardiac index increased at 3 months, reflecting improved hemodynamic function despite reduced fractional shortening.
• Three dogs (3.9%) died postoperatively, highlighting a 96.1% survival rate within 3 months.
• The repair technique involved artificial chordal replacement and annuloplasty; no cleft closure or leaflet suturing was used.
• Color Doppler echocardiography confirmed substantial reduction in mitral regurgitation postoperatively in most dogs.

🔍 Key Findings

• The study was a prospective clinical trial evaluating the efficacy of a three-dimensional (3D)-printed, patient-specific reduction system for aligning diaphyseal tibial fractures stabilized using minimally invasive plate osteosynthesis (MIPO) in fifteen client-owned dogs.
• Virtual surgical planning (VSP) and fabrication were feasible within a clinically relevant timeframe, with a mean of 50.7 hours. Surgical efficiency improved with experience.
• Pin-guide placement was accurate, with median translational discrepancies of 2.7 mm (proximal) and 2.9 mm (distal), and angular discrepancies highest in the axial plane.
• The proximal guide was easier to apply (median Likert score: 8) than the distal guide (median: 6).
• The 3D-printed system enabled near-anatomic reduction in 87% of cases and acceptable reduction in the remaining 13%; no unacceptable reductions occurred.
• Postoperative alignment and tibial length were well-restored, with all dogs within 5° or 5 mm of contralateral measurements.
• Temporary circular fixation was occasionally used to assist reduction and improve alignment.
• Precontoured plates fit easily, with a median Likert score of 9; total surgical time was shorter than conventional MIPO at the institution.
• The study lacked a control group but builds on prior cadaveric feasibility work.

🔍 Key Findings

• Microvascular density at the site of foreign body obstruction was significantly lower in obstructed dogs compared to healthy controls.
• PBR (perfused boundary region) was paradoxically lower in obstructed dogs, indicating that PBR may not reliably correlate with tissue viability in this context.
• No significant difference in microvascular perfusion between subjectively viable vs nonviable intestines, suggesting subjective assessment is unreliable.
• No difference in perfusion parameters between handsewn and stapled enterectomies, indicating both techniques preserve vascular health equally.
• Stapled enterectomy using green TA staples is safe and did not impair intestinal perfusion at the anastomosis site.
• SDF videomicroscopy is feasible intraoperatively and can differentiate healthy from diseased intestine in dogs.
• Surgeons' subjective evaluations led to potentially unnecessary enterectomies, as microvascular parameters did not differ.
• No cases of dehiscence or mortality, suggesting both surgical approaches are effective when applied properly.
