In Moreira 2024 et al., on predictive equations for TPA correction, what was the purpose of the generated corrective equations?
🔍 Key Findings
- A linear relationship was observed between wedge angle and tibial plateau angle (TPA) correction across all four CCWO techniques.
- All techniques produced predictable TPA corrections using linear regression-derived equations, allowing wedge angle extrapolation to achieve a target postoperative TPA of 5°.
- TLA shift (tibial long axis) increased with wedge angle and influenced final TPA; greatest in Frederick & Cross method.
- Tibial shortening (mTL%) varied by technique, being most severe (up to 40.9%) in traditional Slocum & Devine CCWO and least in newer techniques (7.5–12%).
- The Oxley mCCWO technique showed lower TLA shift compared to the Frederick & Cross and Christ techniques, though similar to Slocum & Devine; tibial shortening was more pronounced than other modified techniques at wedge angles ≤40°.
- Techniques varied in craniocaudal translation and wedge apex positioning, influencing planning accuracy and mechanical axis alignment.
- The corrective wedge angle equations reliably predicted TPA within 4–6° across varied tibial conformations.
- The study supports equation-based planning over static TPA–5° subtraction to reduce risk of under- or over-correction.

In McNamara 2022 et al., on transoral endoscopic arytenopexy, which of the following best describes the tissue fixation performed during TEA?
🔍 Key Findings
- TEA significantly increased the rima glottis area (RGA) from a mean of 0.52 cm³ to 0.78 cm³ (p < .0001)
- Mean RGA increased by 157%, equivalent to an 84% estimated decrease in airway resistance
- LEGS (laryngeal epiglottic-glottic seal) remained intact in all cadavers post-procedure, indicating maintained airway protection
- TEA was technically feasible in all 15 cadaveric dogs using a custom endoscopic gag port (EGP)
- TEA avoids cervical dissection, potentially reducing surgical trauma and risks compared to UAL (unilateral arytenoid lateralization)
- Compared to UAL, TEA showed slightly less RGA increase, but greater LEGS preservation, potentially reducing aspiration risk
- No cartilage was included in sutures; arytenopexy involved soft tissue fixation to pharyngeal wall across the piriform recess
- Cadaver model limitations include inability to assess functional outcomes like swallowing and respiratory motion impact

In Dalton 2023 et al., In Minimally invasive acetabular fracture repair in dogs, what was the primary purpose of using mirrored 3D-printed hemipelves in this study?
🔍 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.

In Zann 2023 et al., In Long-term outcomes after proximal humeral OC debridement in dogs, what difference was noted in affected limbs compared to contralateral limbs in unilaterally affected dogs?
🔍 Key Findings
- 20 dogs (26 shoulders) evaluated at mean 3.5 years post-surgery after arthroscopic or open debridement.
- Ipsilateral muscle atrophy and decreased range of motion (↓ extension, ↓ flexion) in affected limbs compared to contralateral healthy shoulders.
- All treated shoulders developed osteoarthritis, confirmed radiographically, by CT, and arthroscopically.
- Moderate to severe synovitis was present in all shoulders; lesions showed patchy, incomplete cartilage infilling even up to 8.9 years post-op.
- Kinetic gait analysis showed no significant differences in PVF/VI between affected and unaffected limbs, despite mild lameness clinically.
- Owners reported good to very good mobility (median LOAD = 6), often underestimating clinical lameness.
- CT detected larger lesion dimensions than radiographs (wider, deeper defects).
- Despite progression of OA, surgical debridement was associated with satisfactory long-term function, though not prevention of degenerative changes.

In McNamara 2022 et al., on transoral endoscopic arytenopexy, what limitation of the cadaver model was specifically mentioned regarding functional outcomes?
🔍 Key Findings

In Story 2024 et al., on surgical correction of excessive tibial plateau angle (eTPA), which two techniques demonstrated the most accurate achievement of their target TPA values?
🔍 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.

In Chitty 2025 et al., on tibial fracture fixation in immature dogs, which complication was most common in the external fixation group?
🔍 Key Findings
Internal fixation (IF) group (n=59):
- Complication rate: 20.3%
- Major complications: 15.3%
- Longer time to discharge if complications occurred (median: 12.5 weeks)
External skeletal fixation (ESF) group (n=36):
- Complication rate: 55.6% (p < .001 vs IF)
- Major complications: 52.8%
- Most common issue: pin tract morbidity
Multivariable analysis:
- Use of IF significantly reduced odds of complications (OR 0.23, p = .004)
- Use of post-op antibiotics associated with increased odds of complications (OR 3.53, p = .028)
Fixation choice influenced by age:
- Older puppies more likely to receive IF (OR 1.25 per week increase in age, p < .001)
Breed & fracture distribution:
- Common breeds: Labrador, Border Collie, Whippet
- Common fracture sites: middle and proximal third of tibia

In Monnet 2023 et al., on barbed vs conventional suture in vesicourethral anastomosis (VUA), how did the number of suture bites compare between the UBS and conventional groups?
🔍 Key Findings
- Leakage pressure was not significantly different between unidirectional barbed suture (UBS) and conventional (C) suture groups (p = .236).
- UBS group had a 28% lower median leakage pressure than the C group (8.6 mmHg vs. 11.7 mmHg), suggesting higher biological risk of leakage.
- UBS significantly reduced suturing time (median 12.7 vs. 17.3 minutes; p < .0002).
- Fewer suture bites were needed in the UBS group (median 14 vs. 19; p = .012).
- No suture breakage or urethral narrowing occurred in either group.
- Leakage site distribution (ventral vs lateral) was similar between groups; no dorsal leaks noted.
- Leakage occurred as low as 5 mmHg in UBS group, indicating potential for postoperative extravasation.
- UBS may aid intracorporeal suturing in minimally invasive prostatectomy, but catheterization remains necessary postoperatively.

In Caldeira 2025 et al., on femoral neck fixation, what was the main mechanical advantage of using three cannulated screws over two?
🔍 Key Findings
Design: In vitro study on cadaveric femurs (n=21) with basilar femoral neck fractures stabilized using 2 vs 3 titanium cannulated screws.
Stiffness: Control > 3-screw > 2-screw (674 > 120 > 90 N/mm).
Yield Load: 3-screw (586 N) > 2-screw (303 N); both < intact femur (2692 N).
Displacement: No difference across groups.
Complication: 3-screw technique more demanding; higher risk of cortical perforation, especially with narrow femoral necks.
Failure Mode: Dislodgement of femoral head + screw shaft bending.
Conclusion: 3 screws = stronger construct than 2 screws. Clinical implications need further study.
