In Scheuermann 2024 et al., on 3D-printed reduction guides for tibial fractures, what was the most common plane for angular pin-guide placement error?
🔍 Key Findings
- The study was a prospective clinical trial evaluating the efficacy of a three-dimensional (3D)-printed, patient-specific reduction system for aligning diaphyseal tibial fractures stabilized using minimally invasive plate osteosynthesis (MIPO) in fifteen client-owned dogs.
- Virtual surgical planning (VSP) and fabrication were feasible within a clinically relevant timeframe, with a mean of 50.7 hours. Surgical efficiency improved with experience.
- Pin-guide placement was accurate, with median translational discrepancies of 2.7 mm (proximal) and 2.9 mm (distal), and angular discrepancies highest in the axial plane.
- The proximal guide was easier to apply (median Likert score: 8) than the distal guide (median: 6).
- The 3D-printed system enabled near-anatomic reduction in 87% of cases and acceptable reduction in the remaining 13%; no unacceptable reductions occurred.
- Postoperative alignment and tibial length were well-restored, with all dogs within 5° or 5 mm of contralateral measurements.
- Temporary circular fixation was occasionally used to assist reduction and improve alignment.
- Precontoured plates fit easily, with a median Likert score of 9; total surgical time was shorter than conventional MIPO at the institution.
- The study lacked a control group but builds on prior cadaveric feasibility work.

In Antonakakis 2022 et al., on telovelar tumor resection, what postoperative imaging finding confirmed complete resection of the tumor?
🔍 Key Findings
- Telovelar approach enabled complete resection of a fourth ventricle choroid plexus tumor in a dog without postoperative complications.
- Postoperative MRI confirmed gross total tumor removal, and the dog remained neurologically normal 28 months post-surgery.
- The tela choroidea was used as a surgical landmark and incised to allow atraumatic access to the tumor.
- Cerebellum was spared using this technique, minimizing risk of cerebellar injury (e.g., cerebellar mutism).
- No hemorrhagic complications were noted during surgery due to dissection through avascular planes.
- Histopathology favored choroid plexus carcinoma based on mitotic index (9/10 HPFs), though definitive diagnosis remained pending.
- The case highlights the utility of telovelar over transvermian approach, given its minimally traumatic nature and improved exposure.
- Survival beyond 2 years without adjunctive therapy suggests surgical excision alone may be curative in select cases.

In Low 2025 et al., on machine-learning outcomes in IVDE, which factor was associated with improved functional recovery?
🔍 Key Findings
The study included 162 deep-pain-negative dogs undergoing decompressive surgery (hemilaminectomy) for acute thoracolumbar intervertebral disc extrusion (IVDE).
Ambulatory recovery occurred in 53.1% of dogs (86/162).
The best performing machine-learning model was XGBoost, with an AUC of 0.9502 and accuracy of 89.1%, outperforming Ridge, AdaBoost, and Naive Bayes models.
Preoperative-only XGBoost models were less accurate, with AUC dropping to 0.8271 and accuracy to 71.9%.
Top predictive features (by SHAP analysis) included:
- T2-weighted to L2 spinal cord signal ratio (lower values predicted better outcome)
- Use of fenestration (presence associated with better recovery)
- Hospitalization duration
- Imaging modality used
- Duration of nonambulatory status
Machine learning provided better insight into prognostic factors than traditional statistical methods.

In Adair 2023 et al., on PCCLm vs. open cystotomy, what factor increased the odds of surgical site infection/inflammation in the PCCLm group?
🔍 Key Findings
- PCCLm resulted in significantly fewer postoperative lower urinary tract signs compared to OC (13.0% vs 60.9%, p <.001).
- Incomplete urolith removal was not significantly different between PCCLm and OC (11.4% vs 20%, p = .112).
- PCCLm had significantly shorter anesthesia times than OC when no concurrent procedures were performed (97.5 vs 120 min, p < .001).
- Surgical site infection/inflammation (SSII) rates were low and not significantly different between groups (4.5% PCCLm vs 1.8% OC).
- Dogs undergoing PCCLm were more frequently discharged same-day (84.7% vs 0% in OC), reflecting faster recovery.
- PCCLm had higher intraoperative complication rates (22.1% vs 3.4%), mostly due to incision extension or conversions.
- Time to additional surgery for urolith recurrence was longer in PCCLm dogs (24 vs 11.5 months, p = .004).
- Calcium oxalate uroliths were more prevalent in PCCLm cases, while OC had more struvite or mixed types.

In Bilmont 2025 et al., on cup version comparison, which variable most affected open face version without significantly changing truncated face version?
🔍 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.

In Sullivan 2025 et al., on TTT stabilization methods, which stabilization method showed significantly different failure force or stiffness?
🔍 Key Findings
- Spacer pin fixation showed no difference in failure force or stiffness compared to tension band wire (TBW) or 2-pin techniques.
- All constructs failed under loads >1000 N, exceeding estimated peak quadriceps force in dogs during walking (~240 N).
- Patellar ligament failure was the most common mode of failure across all groups (5–8 samples per group).
- Distal tibial crest fractures were seen only in 2-pin and spacer pin groups, not in TBW group, suggesting TBW may protect against crest failure.
- No failures occurred at pin tracts, possibly due to pin placement within patellar ligament footprint.
- Spacer pin technique avoids placing pins through the tuberosity, potentially reducing risks of soft tissue complications like tendinopathy or irritation.
- Use of partial osteotomy with robust distal crest may substitute for TBW without compromising initial mechanical strength.
- Further in vivo or cyclic loading studies are required, as this cadaveric study tested only acute tensile failure.

In Pfeil 2024 et al., on fluoroscopic pinning, what was the median time to radiographic bone union?
🔍 Key Findings
- Fluoroscopically guided normograde metabone pinning (FGNMP) was used to treat 17 animals (15 dogs and 2 cats) with 57 metabone fractures, including various fracture configurations (short-oblique body, physeal, and comminuted).
- All 57 fractures were stabilized using intramedullary pins via FGNMP. The study exclusively focused on pin fixation and did not include screws or combined fixation techniques.
- Median surgical time was 54 minutes (range 26–99 min), indicating efficient procedural execution.
- Radiographic bone union was achieved in all fractures, with a median time to union of 6 weeks (range 4–12 weeks). Union was confirmed in all initially non-united fractures on follow-up.
- No major complications were reported. A single pressure sore at the olecranon resolved uneventfully, and no pin migration or osteomyelitis was observed.
- Pin extensions were noted radiographically (e.g., 42% distal subchondral overextension), but were not associated with clinical problems.
- Fluoroscopic guidance improved implant accuracy and preserved soft tissue, enabling effective fracture alignment and stabilization using this minimally invasive osteosynthesis (MIO) approach.
- The authors concluded that FGNMP is an effective, safe, and minimally invasive method for a variety of metabone fracture types, yielding quick recovery, fast healing, and good to excellent long-term functional outcomes in all 17 cases.
