🔍 Key Findings

• 48% of the intra-articular biceps tendon was visible at a standing angle; this increased to 63% in flexion (p = 0.0003).
• 58% of the medial glenohumeral ligament's cranial border was within view.
• 20% of the subscapularis tendon was visualized via the standard lateral arthroscopic approach.
• Visibility was assessed using tattoo ink markers and confirmed via dissection in cadavers.
• Limitations of standard lateral portals may lead to underdiagnosis of deeper or distal pathology in these structures.

🔍 Key Findings

• FFP resulted in longer median surgery (75 min) and anesthesia (111 min) durations than S (51 min and 80 min, respectively).
• No significant difference in anesthetic complications, regurgitation, aspiration pneumonia, or hospitalization time between S and FFP.
• Major complications were rare (4%) and equally distributed between procedures; included tracheostomy and euthanasia due to severe airway disease.
• Postoperative oxygen use was common (52% of dogs) but not significantly different between procedures.
• FFP dogs more often had laryngeal collapse (especially Grade 1: 68% vs. 32% in S dogs).
• Most dogs (85%) had concurrent nares surgery, with caudal wedge resection more frequent in FFP dogs.
• Few dogs needed revision soft palate surgery (7/124 total); similar between groups.
• Postoperative clinical signs improved across both procedures; regurgitation was the most persistent sign post-op.

🔍 Key Findings

• Fewer R1 margins (tumor on ink) were achieved in mast cell tumors (MCTs) when using 6–10 mm lateral margins versus 0–5 mm (7% vs. 55%; _P_ = .049).
• For soft tissue sarcomas (STSs), no benefit was seen in margin completeness between 0–5 mm vs. 6–10 mm lateral margins (41% vs. 43% R1).
• Overall R1 rates were 26% for MCTs and 42% for STSs following PNE.
• R scheme (“tumor on ink” = R1) had better interobserver agreement (83%) compared to ≤1 mm margin criteria (68% agreement).
• Complication rate was moderate (26%), but no surgeries required revision.
• Local recurrence/metastasis occurred in 14% of dogs, with 60% of those having R1 margins.
• Adjunctive therapy was considered clinically indicated in 46% of 0–5 mm margin cases vs. 24% of 6–10 mm cases.
• Histologic grade and tumor size were not predictive of margin completeness.

🔍 Key Findings

The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).

Ambulatory recovery occurred in 53.1% of dogs (86/162).

The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.

Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.

Top predictive features (by SHAP analysis) included:

1. T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
2. Use of fenestration (presence associated with better recovery)
3. Hospitalization duration
4. Imaging modality used
5. Duration of nonambulatory status

Machine learning provided better insight into prognostic factors than traditional statistical methods.

🔍 Key Findings Summary

• Subtotal coronoidectomy improved vertical and propulsive forces, but braking forces remained subnormal at 26 weeks.
• No significant benefit was seen from ACP vs placebo at any timepoint across all force parameters or lameness scores.
• Force plate analysis was more sensitive than visual lameness scoring.
• Braking force (%FY+) was best at detecting persistent lameness, and SI < 0.9 persisted in most dogs at 26 weeks.
• Outcome less favorable than historically reported — challenges status of subtotal coronoidectomy as “gold standard” for MCD.

🔍 Key Findings

• 3D-printed cannulas (3DPCs) reduced mean surgical time significantly in cadaveric procedures (125.6 vs 95.2 min, p = 0.03).
• Cannula pullout events decreased from a mean of 10 to 2.2 per procedure when using only 3DPCs (p = 0.03).
• Instrument collisions were significantly fewer with 3DPCs (6.8 vs 2.6 collisions, p = 0.03).
• Live patients experienced no postoperative complications, including no incision site infections or discomfort.
• Initial versions of 3DPCs had minor issues, including valve leakage and looser trocar fit, requiring surgical workarounds.
• Customization of cannula shaft length (3 cm vs standard 5–8.3 cm) improved working space and reduced instrument interference.
• Production cost was under $5 per cannula, suggesting 3DPCs may be a cost-effective and reusable alternative for small patients.
• Study supports broader use of 3DPCs in laparoscopic procedures requiring long-jawed instruments or intricate tissue handling.

🔍 Key Findings

• Overall closure-related complication rate was 14.1%, lower than previously reported (17–78%).
• No clinically meaningful difference in complication rate between orthopedic wire (17.4%) and suture (11.5%) closure methods.
• Dog size (≥20 kg) was the only significant risk factor associated with increased closure-related complications (p = .01).
• Type of closure (wire vs. suture) did not affect risk, even in larger dogs.
• Suture closure showed a non-significant trend toward fewer complications (mean reduction 2.3%, 95% CI: –9.1% to +4.5%).
• Most complications were mild (62%), with only 10 severe cases requiring surgical revision.
• Infection rate was low (2.7%), and not significantly different between wire and suture.
• Suture closure is a valid alternative to wire, including in large dogs, based on this large, multi-institutional study.

🔍 Key Findings

• Both free-hand probing (FHP) and 3D-printed guides (3DPG) enabled accurate spinal pin placement, with 87.5% vs 96.4% of pins graded as optimal (Grade I).
• 3DPGs had fewer intraoperative deviations (0/56 pins) compared to 6/56 with the FHP technique.
• No pins using either method fully breached the medial vertebral canal (Grade IIb) — a critical safety outcome.
• Pins placed using 3DPGs required less time overall (mean 2.6 min) than FHP (mean 4.5 min).
• FHP required specific experience and has a learning curve, whereas 3DPG use requires CAD software and 3D printing access.
• FHP had more lateral canal violations (Grade IIIa: 4/56 vs 0/56 for 3DPG), suggesting slightly less precision.
• Both techniques were safe, and all deviations were recognized and corrected intraoperatively.
• 3DPGs may offer practical advantages in clinical settings lacking surgical expertise, while FHP allows immediate intervention without 3D printing delay.

🔍 Key Findings

• Distal femoral shortening osteotomy (DFSO) enabled prosthesis reduction in all 4 dogs with irreducible luxoid hips undergoing total hip replacement.
• Median femoral shortening ratio was 13.8% (range: 10.7–15.3%) based on intraoperative tension needed for prosthesis reduction.
• Bone union was achieved in all cases post-DFSO, indicating good healing potential.
• Two major complications occurred: one prosthetic luxation and one aseptic stem loosening requiring explantation.
• One intraoperative fracture of the greater trochanter occurred during trial reduction before DFSO.
• DFSO did not result in neurovascular injury, even in cases with significant femoral head displacement (>4 cm).
• Radiographic planning with FHD index and intraoperative assessment were crucial for determining DFSO necessity.
• DFSO avoids complications linked to subtrochanteric osteotomy by preserving proximal femoral anatomy and allowing secure distal fixation.

🔍 Key Findings

• Arthroscopically assisted stabilization with an IAD was feasible in cadaveric canine shoulders using both bone anchor and suture-toggle techniques.
• Suture-toggle repair was successfully performed in all specimens, while bone anchors could not be deployed in 3/10 shoulders, indicating lower feasibility.
• Median surgical time was shorter for the suture-toggle group (25.5 min) compared to the anchor group (37.3 min).
• Postoperative abduction angles returned to baseline in the anchor group, while the suture-toggle group had slightly reduced angles, suggesting possible overtightening.
• Violation of the articular surface occurred in 2 anchor specimens and 1 suture-toggle specimen, but none were considered likely to be clinically significant.
• Overall targeting accuracy using the IAD was 88%, supporting its utility in guiding tunnel/anchor placement.
• CT measurements showed acceptable bone stock and insertion angles, but anchor insertion angles were lower than optimal for mechanical pullout strength.
• Suture-toggle technique was considered simpler and more consistent, with fewer complications and faster execution than anchor placement.
