🔍 Key Findings

Incidence of BFX lateral bolt stem breakage: 2.95% (13 dogs, 14 stems)

Implant factors:

• 13/14 were BFX lateral bolt stems (sizes #5–7)
• +9 necks used in 5/11 of 17 mm heads
• 10/14 stems undersized based on radiographs
• 10/13 dogs exceeded weight limits for implanted stem size

Malalignment:

• 10/14 had varus alignment (median 3.9°)
• 8/14 had insufficient proximodistal seating

Breakage site: Proximolateral shoulder in all cases

Revision outcomes:

• 11 revised (7 CFX, 3 larger BFX, 1 collared)
• 9/10 revised dogs regained full function
• Complications: 1 rebreakage, 1 periprosthetic fracture, 1 fixation failure

Histopathology:

• Electron microscopy showed fatigue striations and incomplete bead fusion

Conclusion: Avoid small BFX lateral bolt stems if undersized or if long necks required; use weight guidelines to prevent fatigue failure.

🔍 Key Findings

• Two-pin fixation had significantly greater strength (639 N) than single-pin fixation (426 N) in TTAF models (p = .003).
• Stiffness was also higher with two-pin constructs (72 N/mm vs 57 N/mm); statistically significant (p = .029).
• Both fixation types withstood loads greater than quadriceps force in dogs at a walk (240 N), indicating clinical viability.
• Failure was most commonly due to pin bending or pullout (82%), with fewer cases of ligament tearing or epiphyseal fracture.
• K-wire insertion angle (KWIA) did not significantly differ between fixation types (p = .13).
• Single larger pins delivered ~68% of the strength and ~83% of the stiffness of two smaller vertically aligned pins.
• Clinical implication: Two vertically aligned pins are biomechanically superior for TTAF fixation in canine models.
• Study used mature cadavers, which may underestimate loads and stiffness compared to immature clinical cases.

🔍 Key Findings

Sample: 21 cats (10 control, 11 affected); 14 normal limbs vs 18 with MPL (MPL II: 7, MPL III: 11).

Significantly different CT measurements in MPL vs control:

• aLDFA: MPL II > control and MPL III (p = 0.014)
• FTW: MPL III > control (p = 0.021)
• FTD: control > MPL II and III (p < 0.001)
• TTA: MPL II and III had increased external tibial torsion vs control (p < 0.001)
• fPL and PV: MPL III cats had longer and more voluminous patellae

No significant differences in AA, mMPTA, TTD, fPW, aPH.
Patella width exceeded trochlear width in all groups.
Authors suggest femoral and tibial angular correction may not be indicated in most feline MPL II–III cases.
Soft tissue techniques and trochleoplasty warrant further investigation.
CT method: Intraobserver ICC good in 64%, interobserver poor in 36% of metrics.

🔍 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.

🔍 Key Findings

• Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
• Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
• Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
• Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
• Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
• Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
• PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
• Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.

🔍 Key Findings

• Lateral humeral condylar fractures (LHCF) were most common, comprising 63.6% of cases.
• Transcondylar screw (TCS) + K-wire(s) fixation had a 7.62x higher risk of major complications compared to other methods (p = .009).
• All cases of TCS migration occurred in the TCS + K-wire group; none occurred with plate fixation.
• Overall complication rate was 40.9%, with 29.5% being major and requiring intervention.
• Contralateral humeral intracondylar fissures (HIF) were found in 58.1% of French Bulldogs with CT data.
• No significant association between age and presence of HIF, but fissure length increased with age (R = 0.47, p = .048).
• Younger, lighter dogs had higher complication and screw migration rates, possibly due to softer bone and smaller condyles.
• TCS + plate fixation had the lowest complication rate, suggesting biomechanical superiority.

🔍 Key Findings

• Cholelithiasis was the most common indication for cholecystectomy in cats.
• Perioperative complications were frequent, with intraoperative hypotension in all recorded cases and postoperative anemia in 14 cats.
• Perioperative mortality was 21.7%, lower than historical rates for feline biliary surgery.
• 78.3% of cats survived to discharge, and 83.3% of those lived >6 months; 44.4% survived >3 years.
• Vomiting was the most common short- and long-term complication, though most cats were medically managed.
• Concurrent EHBDO was not a contraindication provided CBD patency was restored.
• Positive bacterial cultures were found in 15 cats, with E. coli and Enterococcus faecalis most common.
• Owner-reported outcomes were excellent in all cats that survived long-term.

🔍 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

🔍 Key Findings

Synovitis was present in 100% of canine stifles with CCL disease (n = 163).

The most frequent severity score was 3/5 (55.2%), followed by 4/5 (24.5%).

Higher synovitis scores were significantly associated with:

• Higher median cartilage scores (p = .042, OR = 2.1 per unit increase)
• Longer duration of clinical signs (p < .001, OR = 1.27 per month)

Bodyweight (p = .083) and sex (p = .17) were not statistically significant in multivariable analysis.

Bucket handle meniscal tears were not associated with synovitis severity.

Clinical implication: Earlier intervention may help reduce synovitis and slow OA progression.

🔍 Key Findings

• Intraoral approach (IOA) reduced surgical time compared to lateral orbitotomy (median: 42.0 vs 65.7 minutes, p = .005)
• Ease of closure (Stage III) was better with IOA (p < .001), though gland removal (Stage II) was easier with LOA (p = .039)
• Complete gland removal was achieved in 8/10 IOA vs 10/10 LOA cases in cadaveric study
• All 3 clinical cases had uneventful recoveries post-IOA, including one carcinoma, with no intra- or short-term postoperative complications
• LOA had superior surgical exposure, but was more invasive and time-consuming
• IOA posed greater difficulty in complete gland removal in brachycephalic dogs, with remnant tissue noted in 2/10 cadavers
• IOA avoids osteotomy, reducing potential complications like delayed union and postoperative pain
• Cosmetic outcomes and healing were better with IOA, and no E-collar was required postoperatively
