🔍 Key Findings:

• Sample: 24 canine cadavers, 477 total pins across 240 vertebrae.
• Technique Comparison: 3D printed guides (3DPG) vs freehand (FH).
• Acceptable Placement Rates: 3DPG = 87.5%, FH = 69.8% (p < .0001).
• Odds Ratio for FH: 0.28 (95% CI 0.16–0.47), significantly less likely to yield acceptable placement.
• Worst Accuracy Locations: T10 (OR 0.10), T11 (OR 0.35).
• Surgeon Impact: Surgeon 2 outperformed others (OR 9.61, p = .001).
• Modified Zdichavsky Classification used to score implant accuracy (Grades I–IIIb).
• Primary Benefit of 3DPG: Increased safety and precision, regardless of surgeon experience.

🔍 Key Findings

• 3D-printed endoscopy ports (3DEP) enabled accurate ventral slot creation in cadaveric dogs at C3–C4, regardless of surgeon experience.
• Screw trajectory accuracy was high, with mean angular deviation <2.5°, entry/exit point deviation <1.6 mm, and <0.6 mm screw penetration into the spinal canal.
• No statistical differences were found between experienced and inexperienced surgeons for slot dimensions or screw placement accuracy.
• Ventral slot length and width ratios were within recommended limits, averaging ~30% and ~46% of vertebral body dimensions, respectively.
• 27/30 slots were classified as ideal (Type I), with all 3 deviating cases still considered clinically safe.
• 3DEP design allowed precise alignment and fixation, reducing risk of tilting and improving visualization without soft tissue intrusion.
• Custom dilator system facilitated safe, repeatable MISS approach without need for retractors or excessive tissue manipulation.
• Debris containment and suction through the 3DEP improved visualization, compared to conventional MISS techniques.

🔍 Key Findings

• Feasibility study in 5 canine cadavers plus 1 clinical case (Chihuahua, 5.5 kg).
• Technique used two small approaches (caudal and craniolateral) connected with an epiperiosteal tunnel.
• Plates were precontoured on mirrored 3D-printed hemipelves to improve fit and reduce intraoperative bending.
• Cadaver outcomes: fracture gap <2 mm, step defect <1 mm, pelvic angulation <5°.
• Sciatic nerve injury was minimal: 1/5 cadavers had a mild indentation; others had no gross injury.
• Median total surgical time: ~46 minutes in cadavers; incisions ~5 cm.
• Clinical Chihuahua case: weight-bearing within 24 hrs, radiographic union at 3 months; one screw fractured but no adverse effect.
• Authors conclude: MIAF with 3D printing is feasible and accurate, but requires further evaluation before routine use.

🔍 Key Findings

• 65% of stifles with patella luxation and intact CCLs had increased radiographic soft tissue opacity
• Weight and radiographic OA were significantly associated with increased opacity (p = .0029 and p = .0143)
• Each 1 kg increase in weight increased the odds of opacity by 10%
• Grade of patella luxation, age, and muscle atrophy were not significantly associated with increased opacity
• 19% of dogs with long-term follow-up developed a CCL rupture post-patella surgery, 50% of those had opacity at initial presentation
• Radiographic opacity alone should not be interpreted as CCL disease in dogs with patella luxation
• Radiographic findings likely represent effusion or synovial hyperplasia, not CCL pathology
• Arthrotomy was used to confirm CCL integrity at surgery, but arthroscopy could provide better sensitivity

🔍 Key Findings

Study size: 105 dogs (73 ORPS; 32 MIPO)

MIPO vs ORPS differences:

• Surgical time: MIPO median 130 min vs ORPS 85 min (p < .001)
• Explant rate: MIPO 25% vs ORPS 4.1% (p = .003)
• Time to clinical union: MIPO 85 days vs ORPS 57 days (p = .010)
• Frontal alignment deviation: MIPO 3.5° vs ORPS 2.0° (p = .047)
• Comminution more frequent in MIPO (41% vs 16%; p = .012)

Significant predictors for MIPO use: More proximal fracture margin (p = .004), surgeon identity (p < .001)

No significant difference: Sagittal alignment, radial length, union rate, or complication rate by surgeon

Implant preference: Fixin plates used in 84% of MIPO; locking plates more common in ORPS

🔍 Key Findings

• 97.4% of dogs returned to normal function after total hip replacement using the BFX lateral bolt.
• Mean femoral stem subsidence was 1.22 mm, with most occurring in the first month and minimal thereafter.
• Postoperative complication rate was 13.6%, with 9.2% major and 4.4% minor complications.
• Femoral fractures (3.6%) and coxofemoral luxations (3.6%) were the most common major complications.
• Increased age and higher stem size were risk factors for postoperative femoral fractures; CFI >2.0 was also associated.
• Medial calcar fractures were avoided, and fractures occurred distal to stem ingrowth zone, simplifying repairs.
• Three cases underwent prophylactic plating, all with excellent outcomes and no complications.
• Explant rate was 2.6% (5/195), with most failures involving acetabular cup rather than femoral stem.

🔍 Key Findings

• Aiming device provided comparable trajectory accuracy to fluoroscopy, especially in right limbs (1.9° vs. 3.4°, p = .0128).
• Eccentricity (deviation from condylar center) was lower with fluoroscopy (3.1 mm vs 4.2 mm, p = .0017), making fluoroscopy more precise.
• Odds of joint infringement were 8× higher with the aiming device, though not statistically significant (p = .0575).
• Residents had greater screw trajectory deviation than diplomates (p = .0366), highlighting impact of experience.
• Aiming device procedures took less time than fluoroscopy in some scenarios, particularly for right limbs with right-handed surgeons.
• Fluoroscopic procedures had more pin/drill attempts, increasing risk of glove puncture and potential aseptic breaks.
• Mean deviation angles in both groups (<3.5°) were within acceptable range to avoid intracondylar fracture gap.
• Cadaver model used large-breed, healthy adult dogs, not small-breed immature dogs, limiting generalizability.

🔍 Key Findings

• AMA-based CCWO realigned the anatomical and mechanical axes in 82% of dogs >50 kg, with postoperative AMA angle of 0° in most cases.
• Surgical site infection (SSI) rate was only 0.5%, markedly lower than TPLO-reported rates in similar populations (up to 37.5%).
• All osteotomies achieved Grade 4 healing by 8 weeks, with no implant failures.
• AMA-based planning based on preoperative AMA and TPA allowed for better correction of proximal tibial angulation compared to TPLO in large dogs.
• Use of a double locking plate (DLP) fixation and Robert Jones bandage (RJB) contributed to improved mechanical stability and infection prevention.
• Dogs with AMA angle >3.4° (hyper-CCAPT) were 38% of the cohort, supporting AMA as a critical metric in planning.
• Postoperative alignment of the AA and MA was more consistently achieved when preoperative AMA was >2.4°, confirming suitability of AMA-based CCWO for severe angulation.
• Most infections in TPLOs occur within 15 days, but RJB plus antibiotics in this study appeared protective, suggesting benefit for early-phase SSI prevention.

🔍 Key Findings

• Tibial plateau fractures (TPF) are rare in dogs, but can be surgically stabilized with good outcomes even in complex trauma cases.
• Lateral TPFs (Unger type 41-B1) were approached via caudolateral arthrotomy, with elevation of the lateral meniscus for visualization and use of lag screws and K-wires for fixation.
• Medial TPF (Unger type 41-B2) was addressed via medial parapatellar approach using K-wires and a figure-of-eight tension band.
• One minor complication occurred: implant yield at 2 weeks in a case with a concurrent fibular fracture, resulting in a 0.8 mm step defect.
• No major complications were recorded, and all dogs achieved clinical union with full function by 8–10 weeks.
• Long-term owner-reported outcomes (LOAD scores) were excellent (5/52), indicating minimal osteoarthritis or chronic pain.
• Concurrent fibular fractures may increase risk of implant failure and should influence implant selection (e.g., considering buttress plating).
• Arthroscopic-assisted techniques may be applicable in select cases, but open reduction was preferred due to fragment displacement or concurrent injuries.
