In Scheuermann 2023 et al., on MIPO with 3D-printed bone models, what was the tradeoff of using the FRS compared with IMP reduction?
🔍 Key Findings
- Precontoured plates based on 3D-printed femurs produced accurate femoral alignment (median deviations <3 mm or <3° in all planes).
- Both fracture reduction system (FRS) and intramedullary pin (IMP) methods achieved near-anatomic alignment in cadaveric femoral fractures.
- FRS required fewer fluoroscopic images (median 7 vs. 26, P = .001), but longer surgical time (median 43 vs. 29 min, P = .011).
- Sagittal plane alignment: FRS led to mild increased recurvatum (median 2.9°), but still within near-anatomic limits (<5°).
- Axial alignment: Both groups achieved near-anatomic torsion (<10°), though one IMP case had acceptable (not near-anatomic) alignment.
- Custom drill guides and FRS improved fluoroscopy efficiency but were cumbersome and time-consuming to use. Authors do not recommend current prototype for clinical use.
- Clinical significance: 3D printed models allow accurate precontouring, reducing intra-op plate adjustment; custom guides may reduce radiation exposure for the surgical team.

In Dalton 2023 et al., on acetabular fracture repair, what was the observed rate of sciatic nerve injury in cadaveric repairs?
🔍 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.

In Canever 2022 et al., on labial flap vascular anatomy, which intraoperative technique was used to help locate labial vessels prior to flap design?
🔍 Key Findings
- Superior and inferior labial arteries in cats perfuse robust angiosomes, which support musculomucosal axial pattern flaps.
- Cadaver angiography confirmed vascular anatomy, with consistent patterns between sides and among specimens.
- The vascular supply is located primarily in the musculomucosal layer, not the skin, critical for flap viability.
- Flap harvest requires inclusion of the orbicularis oris (± buccinator) muscle to ensure vascular integrity and flap survival.
- Two clinical cases demonstrated successful use of superior and inferior labial musculomucosal flaps for palatal reconstruction with complete flap survival and resolution of clinical signs.
- Intraoperative transillumination aided vessel localization, facilitating surgical planning and flap design.
- No cases of distal flap necrosis or dehiscence occurred, although mild donor site morbidity (lip retraction, mucosal denuding) was noted.
- These flaps offer a valuable option when local tissues are compromised, especially after failed previous repairs or radiation therapy.

In McCarthy 2022 et al., on 3D drill guide accuracy, what was the advantage of 3D-GDT in terms of drill end point deviation?
🔍 Key Findings
- 3D-printed drill guides (3D-GDT) significantly reduced craniocaudal and dorsoventral drilling angle deviation compared to free-hand drilling technique (FHDT), with statistical significance (p < .0001 and p = .01 respectively).
- No sacral corridor breaches occurred with 3D-GDT, whereas FHDT resulted in 20% drill exit incidences (3/15 cases).
- 3D-GDT had lower deviation from optimal drill trajectory at end points in all axes: craniocaudal (1.84 ± 1.6 mm vs. 4.18 ± 2.4 mm), dorsoventral (1.11 ± 1.0 mm vs. 2.4 ± 1.5 mm), and 3D linear (2.47 ± 1.4 mm vs. 5.35 ± 2.2 mm), all statistically significant.
- Strong correlation (r = 0.77) between CT and 3D software measurements validated method reliability.
- 3D guide trajectories showed consistent proximity to the optimal trajectory, especially at drill endpoints, indicating reduced variability in execution.
- 3D-GDT was developed using open-source software and inexpensive materials, supporting future clinical application.
- Major errors in FHDT occurred primarily at the drill endpoint, underscoring the challenge of maintaining optimal angulation during free-hand drilling.
- The sacral corridor was recharacterized as pyramidal (not quadrilateral), with implications for safer implant placement.

In Lhuillery 2022 et al., on GDV stabilization timing, what was noted about degree of gastric torsion between immediate and delayed groups?
🔍 Key Findings
- Survival rates did not differ between immediate (90 min) and delayed (≥5 h) surgical stabilization groups at discharge or 1-month post-op (approx. 80% survival in both).
- Hyperlactatemia at 24 hours post-fluid therapy was significantly associated with in-hospital and 1-month mortality (P = .01 and P = .02).
- Persistent tachycardia during hospitalization was linked to increased 1-month mortality (P = .015).
- Partial gastrectomy was required in ~6–10% of cases, with high associated mortality.
- Preoperative stabilization protocols (trocarization, nasogastric tube) allowed safe surgical delays up to 13.7 hours without impacting survival.
- Degree of gastric torsion differed between groups; more 0° torsions in delayed cases, potentially due to decompression-induced derotation.
- No difference in post-op complications such as arrhythmias, hypotension, or AKI between groups.
- More intra-anesthetic deaths occurred in immediate surgery group, highlighting importance of adequate pre-op stabilization.

In Huerta 2025 et al., on TPLO healing assessment, which breed had significantly lower healing scores at 8 weeks?
🔍 Key Findings
Population: 29 Boxer dogs and 29 age-matched Labrador Retrievers undergoing TPLO.
Scoring Systems Compared: 5-point vs. 10-point radiographic healing systems.
Healing Scores (Week 8):
- Boxers: 5-point mean = 3.3; 10-point mean = 6.9
- Labradors: 5-point mean = 3.6; 10-point mean = 7.5
- → Statistically significant difference (p = 0.0003 and p < 0.0001)
Osteotomy Gap ≥1 mm (present in 16.4%): Associated with significantly lower healing scores and increased recommendations for additional radiographic follow-up (p < 0.0001).
Observer Reliability:
- Both systems = good interobserver consistency.
- Slightly better intraobserver consistency with the 10-point scale.
Clinical Implication: Boxer dogs may need extended healing time or altered follow-up strategy after TPLO.
