🔍 Key Findings

From Allaith et al., 2023 – Outcomes from a multiuser canine hip replacement registry

• 2375 total hip replacements were analyzed across 1852 dogs, making this the largest multiuser canine THR dataset to date.
• Most common indications for THR were hip dysplasia (51%) and osteoarthritis (34%).
• Implants used included Kyon (46%), BioMedtrix CFX (22%), Hybrid (11%), BFX (9%), and Helica (4.5%).
• Veterinary-reported complication rate was 8.5%, while owner-reported was 23%, with moderate agreement (k=0.44).
• Most common complications: Luxation, femoral fracture, and aseptic loosening.
• BioMedtrix BFX and Helica implants had a higher risk of complications when used after femoral head and neck excision (P = .031).
• Postoperative LOAD scores significantly improved vs preoperative (21 → 11; P < .0001), supporting improved mobility.
• Owner satisfaction was high, with 88% rating outcome as very good or good.

🔍 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

• LVSG was feasible in 9/10 feline cadavers and both live cats, with no intra- or postoperative complications in live cases.
• Two cadavers developed suspected stenosis due to staple lines too close to the lesser curvature; avoided with orogastric tube placement in later cases.
• No evidence of gastric leakage in any cadavers (8/10 tested) or live patients after methylene blue leak tests.
• Mean surgical time was ~110 min cadavers / 115 min live, and 27.6% of stomach mass was resected.
• Both live cats recovered uneventfully, lost 21–24% body weight over 3 months, and had no GI complications at 6-month follow-up.
• Orogastric tube and tension on the greater curvature were critical to avoid staple line misplacement or stenosis.
• No oversew of the staple line was needed, and unreinforced staples showed no leakage in live patients.
• Future studies needed to assess metabolic outcomes and ideal staple sizing and closure techniques.

🔍 Key Findings

• Open face version was significantly greater than truncated face version by 14°–22° (p <.001).
• Open face version increased linearly with inclination and pelvic extension, while truncated face version remained largely stable.
• Truncated face version is an unreliable surrogate for open face version.
• Accurate interpretation of cup version should include both truncated face version and inclination.
• Canine 3D pelvic model and CT-based simulation used for all measurements.

🔍 Key Findings

Design: Ex vivo cadaver study (n=8 dogs, 24 sites)
Comparison: Freehand vs. 3D-printed drill guide-assisted ventral slot (GAVS vs FHVS)
Findings:

• GAVS produced slots not significantly different from planned dimensions (p = .722–.875)
• FHVS produced significantly shorter slots than intended (p < .01)
• No difference in surgical time (p = .071)
• Shape ratio and slot divergence from midline were similar between groups (p > .4)
• Use of guide significantly reduced variability in slot position (63% → 29%), shape (65% → 24%), and divergence (54% → 50%)

Conclusion: 3D-printed guides improved accuracy and consistency of ventral slot creation by novice surgeons; supports future evaluation in live dogs and small breeds

🔍 Key Findings

• Chlorhexidine-based asepsis protocols were comparable to povidone-iodine for reducing surgical site infection (SSI) rates in veterinary surgery.
• No significant difference in skin bacterial colonization was observed between the two antiseptics, at both immediate and delayed timepoints.
• Chlorhexidine-alcohol protocols showed a non-significant trend toward improved bacterial reduction in some studies, though inconsistent across all studies.
• Use of neutralizing agents was inconsistent, which may have led to overestimation of antiseptic efficacy in several studies.
• Formulations and concentrations varied widely (e.g., chlorhexidine 0.5–4%, povidone-iodine 0.7–1%), contributing to heterogeneity and limiting definitive conclusions.
• Only a minority of studies reported using CDC criteria for SSI diagnosis, affecting the reliability of infection outcomes.
• Risk of bias was high or unclear in multiple domains across all included studies, limiting overall confidence in conclusions.
• Meta-analysis confirmed no statistically significant superiority of either protocol for SSI prevention or skin bacterial reduction.

🔍 Key Findings Summary

• 48 dogs (60 stifles) underwent custom 3D-printed TRP implantation for patellar luxation
• 24 treated with TRP alone; 36 with additional procedures (e.g., DFO, TTT)
• Success rate: 59/60 corrected patellar tracking
• Functional outcome: 57/60 full function, 2 acceptable, 1 unacceptable
• Complication rate: 3 total (2 minor, 1 major recurrence)
• TRP spares cartilage unlike trochleoplasty, offering implant-based ridge augmentation
• No implant loosening or infection observed

🔍 Key Findings

• Study population: 36 brachycephalic dogs (20 French bulldogs, 16 pugs).
• Objective: Compare intra- and interobserver reliability for fluoroscopic measurement of nasopharyngeal collapse using two methods:
  • Functional method
  • Anatomically adjusted method
• Key measurements: Minimum (LMin), maximum (LMax) dorsoventral height, and dynamic change ratio (ΔL).
• Outcomes:
  • Intraobserver agreement for ΔL was higher with the functional method (ICC 0.751 vs. 0.576).
  • Observer 1 (radiologist) showed excellent repeatability (>0.9 ICC).
  • Agreement for grading collapse was only moderate (κ ~0.49–0.53), worse than ΔL-based agreement.
  • ΔL ≥ 0.5 to <1 = partial collapse; ΔL = 1 = complete collapse.

🔍 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 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
