In Bae 2025 et al., on SI screw orientation, what was the observed failure mode in all specimens?
🔍 Key Findings
- Ex vivo study using 24 canine cadaver pelves to test screw thread direction in SI luxation.
- Four groups: RhRSI, RhLSI, LhRSI, LhLSI.
- Right-handed screws on right side (RhRSI) had 313% higher torque and 274% higher load vs left side (p < .01).
- Left-handed screws on left side (LhLSI) had 198% higher torque and 195% higher load vs right side (p < .03).
- All failures occurred due to rotation, with no screw breakage or fractures.
- Body weight and moment arm were similar across groups.
- Clinical implication: Use of screw matching handedness to luxation side improves stability.

In Lee 2022 et al., on TPLO accuracy, what was a noted limitation affecting the generalizability of the study?
🔍 Key Findings
- 3D-printed TPLO guides significantly reduced osteotomy inclination angle in both bone models and cadaver limbs compared to jig alone (P < .001).
- Torsional deformities were lower when the 3D-printed guide was used in bone models (P < .001), but not significantly different in cadavers.
- Angular deformities were significantly reduced in cadavers using 3D-printed guides (P < .001).
- Proximal jig pin angulation was more accurate with the guide in cadavers (P < .001); not significant in bone models.
- Medial cortex damage was substantially reduced in bone models when the 3D-printed guide was used (P < .001).
- Postoperative tibial plateau angle (TPA) did not differ significantly between groups, suggesting that clinical alignment can still be achieved without the guide.
- Clinical significance of improved metrics is uncertain, but improved precision may reduce surgical complications.
- 3D guide design allowed direct placement of jig and bone plate, potentially improving workflow and safety.

In Carrera 2024 et al., which technique was used to correct high external tibial torsion in one patient?
🔍 Key Findings Summary
- 5 juvenile dogs (mean age 7.2 months) with grade III–IV MPL were treated surgically.
- Most had femoral varus + external tibial torsion; some had shallow trochlear grooves.
- Distal femoral osteotomy was performed in 4/5 dogs; Tibial tuberosity transposition (TTT) in 3/5; Sulcoplasty in 2/5.
- Mean time to weight bearing: 9.8 ± 5.5 days; healing: 55 ± 24 days
- No reluxations, and final radiographic values for aLDFA and torsion were maintained at 1 year.
- One complication due to domestic trauma, not surgical failure.
- Early surgery appeared to preserve alignment and prevent deformity progression.

In Longo 2022 et al., on CT-guided osteotomies, what clinical outcome was observed in 94% of dogs after femoral and/or tibial detorsional osteotomy?
🔍 Key Findings
- 3D CT volume rendering and CAL measurement successfully guided correction of femoral and tibial torsion in dogs with patellar luxation (PL).
- Physiological patellar tracking was restored in 100% (22/22) of cases after detorsional osteotomy.
- 94% of dogs (17/18) had either full or acceptable functional outcomes post-surgery.
- CAL-based correction was accurate in 19/22 cases, confirming reliability of the measurement technique.
- Complication rate was 45%, with major complications in 2/22 cases—both involved combined femoral and tibial osteotomies.
- Combined femoral and tibial osteotomies in the same limb were linked to a higher risk of complications and poorer outcomes.
- Diaphyseal osteotomies offered more implant space, but metaphyseal locations were associated with faster bone healing.
- Use of a TPLO jig or goniometer was not essential—CAL-based bone marking was sufficient in most cases.

In Lomas 2025 et al., on hybrid THR in cats, what was the most common indication for total hip replacement (THR) in this cohort?
🔍 Key Findings
- Hybrid THR in cats showed no major complications across 17 hips in 15 cats, including 2 bilateral cases.
- Postoperative radiographs confirmed stable implant positioning with no loosening, migration, or dislocation in follow-up imaging.
- Mean owner satisfaction was high, with a mean short-form feline musculoskeletal pain index (sf-FMPI) score of 2/36 at a mean follow-up of 438 days.
- SCFE (slipped capital femoral epiphysis) was the most common indication, seen in 13/17 hips.
- Partial tenotomy of rectus femoris origin resolved intraoperative medial patella luxation in 3 cases—no cats required surgical correction later.
- A micro BFX cup allowed for increased acetabular offset, possibly reducing luxation risk even when using a +0 femoral head offset.
- Hybrid THR was successfully used as a revision for failed CFX THR due to recurrent luxation—implants remained stable post-revision.
- Use of oversized cups (12 mm) with shallow seating or medial breach still resulted in stable outcomes, suggesting good implant fixation even with reduced bone stock.

In Kuvaldina 2023 et al., in Minimally invasive axillary lymphadenectomy in dogs, which technique was used for access in the minimally invasive procedure?
🔍 Key Findings
- A minimally invasive endoscopic technique was successfully developed for excisional biopsy of axillary lymph nodes in dogs.
- The procedure was performed on 4 cadavers (6 limbs) and 3 clinical patients, with no major complications reported.
- Mean cadaveric time: accessory axillary node 5.1 min; axillary node 33 min. One limb had a double axillary node.
- In clinical cases, 2/3 were completed endoscopically; one required conversion to open due to node elevation difficulty.
- Surgical times in clinical cases ranged from 35 to 58 minutes, depending on node accessibility and number.
- Postoperative morbidity was minimal: no lymphedema, minor seroma or lameness resolved quickly.
- The SILS port approach enabled effective access, though precise placement was critical to visualization.
- This is the first reported veterinary endoscopic technique for axillary lymphadenectomy; potential for improved staging and reduced morbidity.

In Caldeira 2025 et al., on femoral neck fixation, what complication was more likely with the three-screw construct?
🔍 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.

In Kershaw 2025 et al., on PSG vs AD, which surgeon experience level was used to assess PSG utility?
🔍 Key Findings
- 3D-printed patient-specific guides (PSGs) significantly improved accuracy of drill hole entry (p < 0.001) and exit (p = 0.044) compared to commercial aiming devices (AD).
- Zero joint penetrations occurred with PSGs, whereas 3 of 7 AD-guided screws were predicted to penetrate the joint (p = 0.19).
- Variance in exit point and drill angle was significantly lower in PSG group, suggesting more consistent results.
- One PSG case failed due to improper guide seating, but this was corrected with improved soft tissue clearance.
- PSGs enabled safer trajectories despite use by novice surgeons, emphasizing their value in less experienced hands.
- Drill holes placed with ADs deviated more cranially and distally, increasing the risk of articular violation.
- Use of PSGs allowed for tighter clustering of drill trajectories, especially in the cranial–caudal axis.
- Subjective feedback favored PSGs for ease of use and ergonomic design, despite requiring slightly larger incisions.

In Power 2022 et al., on liposomal bupivacaine use, what proportion of incisional complications required only topical treatment or no treatment?
🔍 Key Findings
- Overall complication rate was 19.7% (43/218), with most being mild (CSS 1).
- Soft tissue procedures had higher complication rates (26%) than orthopedic procedures (11.6%) (P < 0.01).
- No difference in complication rates between clean, clean-contaminated, and contaminated wounds (P = 0.55).
- No difference in complication rates between labeled use (CCL surgery) and off-label orthopedic procedures (P = 0.21).
- Majority of complications (63%) were mild, resolving without intervention or with topical therapy.
- Severe complications requiring revision surgery were rare (2.3%) and occurred mainly in soft-tissue surgeries.
- Most common complications included SSI (25.6%), dehiscence (16.3%), and seroma (14%).
- Liposomal bupivacaine appears safe for use in broader orthopedic procedures beyond current labeling.
