🔍 Key Findings

• Only 2 of 10 PET implants were fully intact and functional at 6 months post-op.
• Owner-reported function (LOAD scores) improved by 51.7% (p = .008) over 6 months.
• Gait asymmetry improved by 86% (p = .002) postoperatively.
• Implant failure occurred in the midbody of the PET device, suggesting fatigue as a failure mechanism.
• One dog (10%) developed implant infection, necessitating implant removal.
• Implant fixation method (screws + washers + interference screw) was mechanically adequate and technically simple.
• Partially intact implants (4/10) still showed improved clinical outcomes, despite structural compromise.
• Midbody tearing and lack of long-term integrity prohibit continued use of this PET implant in CCL repair.

🔍 Key Findings Summary

• 16 dogs (18 stifles) with CrCL rupture and TPA >34° were treated using the DCTPLO
• Mean TPA correction: from 39.4° to 6.3°
• Bone union at 60 days in 17/18 stifles; remaining healed by 90 days
• Minor complications (e.g., small wedge gaps) in 2/18 stifles — no major complications
• Patellar ligament thickening seen in 16/18 stifles but no clinical signs noted
• The technique enabled safer reduction with less risk of tibial crest fracture vs. conventional TPLO

🔍 Key Findings

• 55 cases (49 dogs, 6 cats) with nonarticular tibial fractures were treated using linear ESF with a minimally invasive approach
• All fractures achieved radiographic union; no unacceptable outcomes were reported
• 40% complication rate, mostly minor (82%), primarily pin-tract morbidity; major complications (7%) included osteomyelitis and refracture
• Open fractures had significantly more major complications than closed ones (P = .019)
• Use of intraoperative imaging (72% cases) reduced surgery time but did not improve alignment (P > .05)
• Median surgery time: 74 min with imaging vs. 100 min without (P = .046)
• TPA was lower than normal in both dogs and cats, but did not correlate with poor outcomes
• 62% had full clinical recovery, and 38% had acceptable outcomes at fixator removal

🔍 Key Findings

• Telovelar approach enabled complete resection of a fourth ventricle choroid plexus tumor in a dog without postoperative complications.
• Postoperative MRI confirmed gross total tumor removal, and the dog remained neurologically normal 28 months post-surgery.
• The tela choroidea was used as a surgical landmark and incised to allow atraumatic access to the tumor.
• Cerebellum was spared using this technique, minimizing risk of cerebellar injury (e.g., cerebellar mutism).
• No hemorrhagic complications were noted during surgery due to dissection through avascular planes.
• Histopathology favored choroid plexus carcinoma based on mitotic index (9/10 HPFs), though definitive diagnosis remained pending.
• The case highlights the utility of telovelar over transvermian approach, given its minimally traumatic nature and improved exposure.
• Survival beyond 2 years without adjunctive therapy suggests surgical excision alone may be curative in select cases.

🔍 Key Findings

• MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
• Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
• MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
• Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
• MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
• Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
• Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
• The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.

🔍 Key Findings

• All four techniques achieved TPA <14°, meeting the threshold for acceptable surgical correction in eTPA cases.
• Group A (CBLO + CCWO) and Group D (PTNWO) showed highest accuracy in achieving target TPA values.
• Group B (TPLO + CCWO) resulted in significant tibial shortening compared to other techniques.
• Group A caused the greatest cranial mechanical axis shift, while Group B caused the least.
• Group C (mCCWO) resulted in consistent under-correction of TPA, despite aiming for 0°.
• Modified or neutral wedge osteotomies (Groups C and D) had minimal effect on tibial length, making them suitable when preservation is important.
• All techniques involved mechanical axis shifts, highlighting the importance of preoperative planning to minimize morphologic disruption.
• Supplemental fixation was standard for all procedures to reduce risks such as tibial tuberosity fracture and plateau leveling loss.

🔍 Key Findings

• Ventricular fibrillation (VF) occurred in 3% of pericardiectomy cases across reporting institutions.
• 14 of 16 dogs (88%) that developed intraoperative VF died, indicating high mortality.
• Electrosurgical devices were used in 15/16 dogs; VF onset coincided with their use in 8 dogs, suggesting a potential but unproven association.
• Preoperative arrhythmias were seen in 7 dogs (e.g., VPCs, VT, bradycardia), possibly serving as early warning signs.
• Thoracoscopic approach was used in 75% of cases; however, conversion to open surgery was required in 9/13 thoracoscopic procedures after VF onset.
• Defibrillation was attempted in 13 dogs, but only 3 converted to sinus rhythm, and only 2 survived postoperatively.
• VF may result from stray current or cardiac manipulation; bipolar energy devices were implicated despite lower theoretical risk.
• Preventative strategies include judicious electrosurgery use, close ECG monitoring, rapid CPR preparedness, and preop cardiac risk assessment.

🔍 Key Findings

• Postoperative complications occurred in 20% of stifles, including 7.5% minor, 10.3% surgical, and 3.4% medical complications.
• The PROSPECT machine-learning model achieved high predictive accuracy: 92.3% for surgical complications, 91.9% for minor, and 94.3% for medical.
• Top predictive features included surgical technique, implant type, patient age, and surgeon identity.
• Surgeon-specific variables influenced predictions, indicating operator experience and technique matter.
• Engineered interaction features (e.g., breed × implant) were more predictive than raw clinical data alone.
• Rottweiler, intact male status, and higher bodyweight were associated with increased complication risk; Labradors had decreased risk.
• Model calibration was strong, especially for high and low probability predictions; midrange predictions were less reliable.
• The model supports individualized, probabilistic risk assessment, which could inform client counseling and tailored postoperative care.

🔍 Key Findings

• 3D-printed models using desktop printers (FDM, LFS) showed submillimetric accuracy, comparable to or better than industrial-grade PJP printers.
• Bone size had a greater effect on print accuracy than printer type, especially in proximal humerus regions.
• The humeral condyle region showed the greatest model accuracy, with mean differences under 0.5 mm, regardless of printer.
• Models tended to be slightly smaller than cadaveric bones, potentially due to systematic underestimation during printing.
• FDM printer provided the highest accuracy at the humeral condyle in medium-sized bones (+0.09 mm).
• LFS printer produced prints faster and more reliably than FDM, although both had comparable dimensional accuracy.
• Statistically significant differences existed, but all were submillimetric and unlikely to impact surgical outcomes.
• Desktop printers are suitable for surgical planning, including plate pre-contouring and patient-specific instrumentation.

🔍 Key Findings

• Dorsoventral radiographs artificially increase Norberg angle values by 3.2–5.8% and should be excluded.
• Lateral pelvic tilt >2° causes asymmetric changes in Norberg angle; >3° results in significant side-specific changes.
• Cranioventral-to-caudodorsal tilt >10° results in obvious radiographic tilt, but changes Norberg angle by only ~2%.
• Tilted but subjectively acceptable images have minor impact and may still be usable for screening.
• Norberg angle readings differed consistently between left/right hips — possibly due to operator handedness.
