In Kang 2024 et al., on sacroiliac fixation strength, which statement best describes screw placement accuracy in both groups?
🔍 Key Findings Summary
- 20 cats with pelvic fractures treated using locking plates with only cortical screws
- 28 fractures stabilized (ilium: 17, acetabulum: 6, ischium: 3, pubis: 2)
- Implants: Primarily 1.5/2.0 mm LCPs or String-of-Pearls plates
- Major complications in 2/20 cases (10%): sciatic entrapment, malunion requiring THA
- Minor complications in 2/20 cases (10%): plate impingement, transient lameness
- Clinical union in all cats by 8 weeks; all cats returned to full function
- Authors conclude cortical screws alone can provide adequate fixation in feline pelvic fractures if screw purchase and bone quality are sufficient

In McLean 2024 et al., what was the average increase in TPA among dogs with rock-back?
🔍 Key Findings Summary
- 95 TPLO procedures reviewed retrospectively with follow-up radiographs
- Rock-back defined as increase in tibial plateau angle (TPA) ≥2° from immediate post-op to recheck
- 21% of stifles (20/95) experienced rock-back
- Mean ΔTPA among rock-back cases = 3.2° ± 2.6°
- No implant failures or tibial tuberosity fractures were reported in these cases
- Plate inclination and exit cut angle (ECA) were not associated with increased risk of rock-back (p = 0.4 and 0.2)
- Authors hypothesize that compression across osteotomy in vivo may mitigate torsional effects from ECA, unlike in gap-model studies
- Emphasizes that rock-back is relatively common, even with well-placed implants

In David 2024 et al., on single-port cryptorchidectomy, why was a 6 mmHg capnoperitoneum preferred?
🔍 Key Findings
- Single-port laparoscopic-assisted cryptorchidectomy (SP-LAC) was feasible in 13/14 dogs with abdominal cryptorchidism.
- Median surgical time was 17 min for unilateral and 27 min for bilateral cryptorchidectomy.
- All testes were successfully exteriorized through a 15-mm mini-celiotomy in most dogs; only 2 needed slight enlargement.
- One major complication occurred (testicular artery hemorrhage, requiring conversion to open surgery).
- Two minor complications involved trocar-related issues (splenic capsule laceration, capnoretroperitoneum).
- No incisional complications were reported postoperatively; some dogs had mild dermatitis at the clipped site.
- The technique requires only one surgeon and no advanced tools beyond a single-port endoscope.
- Low-pressure capnoperitoneum (6 mmHg) was adequate for visualization in most cases.

In Kershaw 2025 et al., on PSG vs AD, what factor contributed to an outlier error in the PSG group?
🔍 Key Findings
- 3D-printed patient-specific guides (PSGs) significantly improved accuracy of drill hole entry (p < 0.001) and exit (p = 0.044) compared to commercial aiming devices (AD).
- Zero joint penetrations occurred with PSGs, whereas 3 of 7 AD-guided screws were predicted to penetrate the joint (p = 0.19).
- Variance in exit point and drill angle was significantly lower in PSG group, suggesting more consistent results.
- One PSG case failed due to improper guide seating, but this was corrected with improved soft tissue clearance.
- PSGs enabled safer trajectories despite use by novice surgeons, emphasizing their value in less experienced hands.
- Drill holes placed with ADs deviated more cranially and distally, increasing the risk of articular violation.
- Use of PSGs allowed for tighter clustering of drill trajectories, especially in the cranial–caudal axis.
- Subjective feedback favored PSGs for ease of use and ergonomic design, despite requiring slightly larger incisions.

In Horwood 2024 et al., on complications in luxoid hip dysplasia, which cup orientation angle was associated with increased risk of postoperative luxation?
🔍 Key Findings
- Luxoid hip dysplasia (LH) was present in 8% of THA cases and significantly increased risk of major complications (p < .001).
- Intraoperative fissures/fractures were 3x more likely in LH dogs vs non-LH (39% vs 16%, p = .001).
- Dorsal luxation was more frequent in LH dogs (28% vs 4%, p = .019).
- Acetabular cup placement with ALO >35° was associated with luxation in LH dogs.
- Morphologic abnormalities (e.g., femoral valgus, lateralization/medialization of cortices) were common in LH and may complicate implantation.
- Despite higher risk, 94% of LH dogs achieved satisfactory outcomes after appropriate revisions.
- Younger age and lighter weight characterized LH dogs (mean age 14.7 months vs 40.9 months, p < .001).
- All LH dogs were treated with cementless stems; prophylactic cerclage was rarely used.

In Israel 2023 et al., on povidone-iodine lavage, what was the calculated break-even cost for the PrePIL protocol?
🔍 Key Findings
- No infections (0/102) occurred in cases where preclosure povidone-iodine lavage (PrePIL) was used, compared to 21/2111 (0.99%) with saline lavage.
- Break-even cost for PrePIL was calculated at $49.74, while the actual cost was only $2.07, confirming strong cost-effectiveness.
- No adverse reactions or healing complications were reported in the 102 PrePIL cases.
- The PrePIL protocol used 0.35% povidone-iodine for 3 minutes before closure, followed by sterile saline lavage.
- Majority of THRs (97%) used cementless fixation (BFX) in PrePIL group; only 3 cases used CFX components.
- Surgeries followed consistent perioperative antibiotic protocols, making PrePIL the only major protocol variable.
- Antibiotics were not added to lavage, aligning with WHO and CDC guidelines for antimicrobial stewardship.
- The infection reduction with PrePIL supports routine use in total hip replacement to reduce periprosthetic joint infections.

In Turner 2025 et al., on TPA changes after SH-1/2 fracture repair, which breed was most represented in the study cohort?
🔍 Key Findings
- TPA decreased significantly from preoperative to follow-up (mean 5.89°; p < 0.001), and from immediate postoperative to follow-up (mean 2.2°; p = 0.018)
- Use of tension band in addition to K-wires did not significantly improve TPA reduction compared to K-wires alone
- Cranial K-wire positioning may attenuate growth at the cranial tibial physis, allowing relative caudal growth to reduce TPA over time
- Dynamic TPA reduction may reduce risk of cranial cruciate ligament rupture even when initial TPA is high
- Small breeds (e.g., French Bulldogs) were overrepresented; further research is needed in larger breeds with more growth potential
- Surgical reduction is difficult, but perfect alignment may not be essential if TPA reduces postoperatively
- Radiographic TPA measurement was reliably performed with low interobserver variability
- K-wire removal at 3–8 weeks may facilitate continued growth in growing dogs

In Ritson 2025 et al., on feline hilar lobectomy sealants, what was the **design benefit** of the double-shank (DS) titanium clip?
🔍 Key Findings
- No leakage occurred using pretied ligature loops (PLL) or double-shank (DS) titanium clips up to 40 cm H₂O airway pressure.
- 1/10 stapled lobes leaked at supraphysiologic pressure (40 cm H₂O), but this was not statistically significant (p = .33).
- All techniques sealed effectively under physiologic and supraphysiologic pressures in cadaveric feline lungs.
- PLL and DS clips required less working space than staplers, making them more practical for small thoracic cavities.
- DS titanium clips offer enhanced security due to dual shanks and tissue-gripping design, reducing clip slippage.
- Leak testing was cyclic and submerged, simulating physiologic ventilation and allowing robust evaluation.
- Stapling failure occurred along the staple line, highlighting risks of air leakage due to staple misalignment or poor hilar access.
- PLL and DS clips may be cost-effective and efficient alternatives for open or minimally invasive feline lung lobectomy.
