🔍 Key Findings

• Case: 9-year-old Labrador with a right caudal pulmonary adenocarcinoma.
• Technique: Peritumoral injection of indocyanine green (ICG) under VATS guidance, followed by near-infrared (NIR) imaging.
• SLN identified: Right tracheobronchial lymph node fluoresced and was safely extirpated.
• Histology: Grade 1 adenocarcinoma, pneumonia, reactive node.
• Outcome: Patient deteriorated and died on postoperative day 3 due to systemic complications (not linked to surgical technique).
• Clinical relevance: First clinical application of SLN mapping for canine pulmonary neoplasia; method feasible with open or minimally invasive approaches.

🔍 Key Findings

• Accurate femoral isometric placement was achieved in 63% of cases, significantly more with SwiveLock (78.6%) than FASTak (38.9%).
• Inaccurate placement was associated with increased internal tibial rotation at follow-up (p = .009), suggesting potential implant failure.
• Pivot shift grade improved in 90.9% of stifles postoperatively, regardless of implant positioning accuracy.
• SwiveLock implants had a faster learning curve and higher placement accuracy than FASTak.
• Higher patient weight was linked to more accurate implant placement (p = .012), likely due to easier anatomical landmark identification.
• No correlation found between implant type or positioning accuracy and final pivot shift grade at 6 weeks.
• Minor and major complications were low and not significantly different between implant types.
• A simplified 2-grade pivot shift system was proposed for clinical use (Grade 1: glide, Grade 2: clunk), aiding intraoperative decision-making.

🔍 Key Findings Summary

• No significant difference in mechanical properties between contoured vs non-contoured SOP-LC rods
• Clamp configuration significantly influenced mechanical performance:
  • Single-side clamps → ↑ yield load, ↑ displacement, ↑ bending strength (p < 0.05)
  • Alternating-side clamps → ↑ initial torsional stiffness (p = 0.029)
• Clamp slippage was evident only in torsional tests; screw loosening may be torque-dependent
• Mild screw bending and construct offset suggest subtle instability
• Recommends clamp configuration choice based on loading scenario
• Suggests 3.0 Nm torque may be more effective than 2.5 Nm to prevent clamp slippage

🔍 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

• Fascia was present over most of the canine forelimb, but key areas like the elbow, carpus, and manus lacked robust fascial planes for wide resection.
• Type I fascia (discrete sheet) was primarily found in the antebrachium, with type IV (periosteal) fascia located at the olecranon, scapular spine, and accessory carpal bone.
• Distal antebrachial fascia was thin and adherent, often blending with carpal structures and lacking reliable surgical planes.
• Partial tenectomy or joint capsule resection was often required for wide excision in the distal limb, especially over the triceps tendon and carpus.
• Nerve transections (e.g., superficial radial or ulnar branches) were commonly needed to maintain fascial margins, though often with minimal functional loss due to overlapping innervation.
• Digital and metacarpal pads lacked clear deep fascial borders, making digit amputation necessary for oncologic margins in distal tumors.
• Dissections revealed fascial junctions as either Type A (easily separable) or Type B (risk of disruption), guiding resection plane selection.
• Findings provide a surgical map to guide preoperative planning for superficial tumor excision on the forelimb.

🔍 Key Findings

• TPLO alone failed to neutralize rotational instability under tibial pivot compression (TPT), despite a negative TCT.
• TPLO combined with lateral augmentation (TPLO-IB) restored both craniocaudal and rotational stability to near-intact levels.
• Cranial tibial translation was 6× greater after TPLO vs intact stifles when tested with TPT (p < .001).
• No significant difference in cranial tibial translation or internal rotation between intact stifles and TPLO-IB group during TCT, eTPT, or iTPT.
• TPLO-IB did not overconstrain the stifle, avoiding excessive external rotation.
• External tibial rotation (eTPT) was more sensitive than TCT in detecting persistent instability after TPLO.
• Excellent intraobserver reliability for both eTPT and iTPT (ICC > 0.9).
• Study supports intraoperative use of TPT to identify cases needing additional rotational stabilization.

🔍 Key Findings

• Open transcholecystic cholangioscopy was feasible using a 3.8 mm disposable flexible endoscope in all 8 canine cadavers.
• Visualization was consistently achieved up to the junction of the hepatic ducts, common bile duct, and cystic duct.
• Advancement past the junction was limited by the endoscope diameter (3.8 mm) and anatomical flexure.
• The 1.9 mm flexible ureteroscope could visualize the entire biliary tree, including the major duodenal papilla, in a large dog (43.8 kg).
• Endoscopic tools (e.g., 3 Fr grasping forceps) could be passed through the working channel only after removing the irrigation line.
• Standard biopsy forceps were incompatible with the disposable endoscope's 1.2 mm working channel.
• Cadaver study showed no rupture, but clinical extrapolation is limited due to lack of diseased tissue.
• Disposable endoscope setup cost (~$6,100) was significantly lower than traditional endoscopy systems (~$75,000–100,000), improving accessibility.

🔍 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

🔍 Key Findings Summary

• Lateral humeral condylar fractures = 69.8% of cases; medial = 16.2%; Y/T = 14.0%
• Falls/stairs were the inciting trauma in 45.6% of cases; significantly younger dogs were more likely to fracture after major trauma (p = 0.01)
• Complication rate = 22% (10 major, 20 minor); implant migration and seroma most common
• Fixation method had no significant impact on complication rates (p = 0.87)
• Epicondylar comminution was significantly associated with complications (p = 0.02, OR = 3.27)
• Contralateral intracondylar fissure found in 9.8%, none progressed to fracture during study
• Wide inter-center variation in complication rate (5–62%, p = 0.002)

🔍 Key Findings

50 dogs underwent bilateral anal sacculectomy using a modified closed technique.
Intraoperative anal sac perforation occurred in 5 dogs (10%), with no postoperative complications in those dogs.
Postoperative complications (43 dogs with follow-up):

• Grade 1 (e.g., scooting, inappropriate defecation): 14/43 (32%)
• Grade 2 (medical treatment needed): 2/43 (5%)
• Grade 3B (revision surgery): 2/43 (5%)

93% of grade 1 and 100% of grade 2–3B complications resolved by two weeks postop.
Technique highlights: direct duct tracking, no anal sac packing, minimal dissection.
