🔍 Key Findings Summary

• Design: Prospective, randomized, double-blinded controlled trial
• Population: 32 brachycephalic dogs undergoing cut-and-sew sharp staphylectomy
• Groups: Adrenaline + lidocaine (Group A) vs. Lidocaine only (Group NA)
• Main Findings:
  • Total hemorrhage significantly lower in Group A (median 1.82 g) vs Group NA (7.95 g); p = .013
  • Normalized hemorrhage significantly lower in Group A; p = .021
  • Surgeon-assigned hemorrhage scores significantly lower in Group A; p = .029
  • No adverse effects (tachycardia, hypertension, arrhythmia, etc.) noted from adrenaline use
  • Breed effect: English Bulldogs bled more overall even after normalization
• Clinical Implication: Adrenaline in nerve blocks reduces hemorrhage without added risk

🔍 Key Findings

• Oversewing the transverse staple line using barbed suture showed no difference in initial (ILP) or maximum leakage pressure (MLP) compared to monofilament suture (p = .439 and .644).
• Barbed suture repairs were ~18% faster (25 seconds faster; p < .001) than monofilament suture.
• No difference was found between unidirectional and bidirectional barbed sutures in leakage resistance or repair time (p = .697).
• Mean ILP and MLP were significantly higher in control jejunal segments (6.6x and 5.1x greater respectively; p < .001).
• Leakage consistently occurred at the crotch of the FEESA in all oversew groups (>80%), not the staple line.
• All oversewn techniques leaked at supraphysiologic pressures, indicating clinical safety against in vivo leakage.
• No leakage was observed from barbed suture holes, addressing concerns of tissue trauma due to barb design.
• The study supports barbed suture as a viable alternative to conventional monofilament suture for FEESA oversew in dogs.

🔍 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

80 toy breed dogs with surgically repaired transverse radius/ulna fractures were analyzed.
Fracture gap in the caudal cortex was present in 46% of cases.
Implant failure rate:

• 27% in cases with fracture gap
• 2% in cases without fracture gap

Fracture gap significantly associated with implant failure:

• OR = 23.0, 95% CI: 2.7–197.9, p = 0.004

Absence of external coaptation also associated with increased implant failure risk:

• OR = 10.1, 95% CI: 1.1–89.6, p = 0.04

Prolonged external coaptation (>1 week) linked to non-implant complications (skin wounds, osteopenia, osteomyelitis):

• OR = 5.4, p = 0.04

Plate thickness, type, open screw holes, and working length were not statistically significant predictors of implant failure after multivariable analysis.

🔍 Key Findings

• Crescent guide use resulted in significantly less medial cortical damage (mean 3.8 mm²) than the radial saw guide (35.7 mm²) and standard jig (51.3 mm²) in bone models.
• No significant difference in osteotomy accuracy (distance of eccentricity, coronal or axial angulation) among crescent guide, radial guide, or standard jig in either bone models or cadavers.
• Device application time was shortest with the crescent guide and longest for the radial saw guide.
• Osteotomy time was fastest with the crescent guide compared to the radial saw guide (P = .015).
• Participants rated the crescent guide easier to apply than both the radial saw guide (P < .005) and the standard jig (P = .015).
• 5 of 6 novice participants preferred the crescent guide over the other devices for performing TPLO.
• Subjective ease of osteotomy performance was higher with the crescent guide vs. radial guide (P < .001).
• Crescent guide does not assist in fragment stabilization or plateau rotation unlike a standard TPLO jig.

🔍 Key Findings

• FGPP (fluoroscopic-guided percutaneous pinning) resulted in successful healing in 10/13 fractures, with good limb function.
• Complications occurred in 5 of 11 cases, including intra-articular implants, malunion, implant failure/nonunion, and implant migration.
• Cases with delayed surgery (>15 days) or radiographic remodeling were more likely to experience major complications.
• Most fractures (10/13) were classified as Salter-Harris type I with mild displacement.
• Median surgical time was 60 minutes, and no conversions to open surgery were needed.
• Postoperative femoral neck resorption was minimal, suggesting possible benefits of the minimally invasive approach for preserving vascular supply.
• One intra-articular pin led to progressive joint disease and required femoral head ostectomy.
• FGPP appears best suited for acute, minimally displaced fractures in young dogs (<8 months) with planned elective explant to avoid growth disturbance.

🔍 Key Findings

• Minimally invasive repair of acetabular fractures using precontoured plates on 3D-printed models is feasible and technically reproducible in dogs.
• All cadavers had fracture gaps <2 mm and step defects <1 mm, indicating accurate reduction.
• Sciatic nerve injury was minimal or absent in all cases, supporting potential neuroprotection from indirect approaches.
• Pelvic angulation was maintained <5°, confirming preservation of alignment post-reduction.
• Surgical time averaged ~46 minutes in cadavers for both approaches and repair.
• Clinical case showed good radiographic healing by 8 weeks and full union by 3 months, with early weight-bearing post-op.
• Use of locking screws improved reduction fidelity, particularly across a broad plate span.
• 3D printing accelerated surgical planning, though its necessity remains debated due to the availability and cost concerns.

🔍 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

• Lymphaticovenous anastomosis (TD to AV) was successfully performed in all 8 feline cadavers using a microvascular anastomotic coupler (MAC).
• Anastomotic patency was confirmed intraoperatively and postoperatively in 7/8 cats via contrast lymphography or retrograde venography.
• Dissection and anastomosis took a median of 120 minutes, with minimal technical complications.
• A 1.5 mm MAC was used in 6 cats, and a 2.0 mm in 2 cats; TD diameter ranged 1.0–1.5 mm, AV up to 2.25 mm.
• Challenges included vessel twisting and luminal patency issues, resolved intraoperatively with minor adjustments (e.g., repeat pinning, tacking suture).
• MAC use eliminated need for hand-suturing, lowering skill demands but requiring precise alignment.
• Technique provides direct lymphatic-to-venous drainage, potentially reducing the stimulus for collateral vessel formation.
• May serve as a future treatment option for feline idiopathic chylothorax, warranting further in vivo studies.
