In McClean 2025 et al., on shoulder arthrocentesis techniques, which of the following best summarizes the accuracy comparison between SA and ST techniques?
🔍 Key Findings
- Study Type: Cadaveric study using 36 paired canine shoulders (n = 18 per group: Subacromial [SA] and Supratubercular [ST])
- Survey Results: 75% of clinicians preferred SA technique; 25% used ST
- Complete accuracy: 50% (SA), 44% (ST) — no significant difference (p = .8)
- Partial accuracy: 39% (SA), 50% (ST)
- Complete miss: 11% (SA), 5.6% (ST)
- Incidence of IACI:
- SA: 50% (9/18 shoulders)
- ST: 11% (2/18 shoulders) → statistically significant (p = .007)
- Lesion depth: All ST lesions were partial-thickness; SA group had one full-thickness lesion (p = .027)
- Location: Lesions found on glenoid and humeral head with even distribution in SA; only one each in ST
- Landmark-guided injections were ≤50% completely accurate, even by an experienced operator.
- ST technique is safer with lower risk of cartilage damage, despite similar accuracy.
- Findings support considering image-guided techniques to improve both safety and accuracy in clinical settings.

In Perez Neto 2025 et al., on hip resurfacing arthroplasty, implantation of the prosthesis reduced maximum load by approximately what percentage compared to controls?
🔍 Key Findings
- In an ex vivo study of 20 canine femur pairs, implantation of a novel hip resurfacing arthroplasty (HRA) prosthesis reduced maximum load (ML) by 22% and load at collapse (LC) by 27% vs. intact controls (p ≤ 0.05).
- Displacement at maximum load (DML), displacement at collapse (DC), and stiffness (k) were not significantly different between prosthesis and control groups.
- Both groups showed similar failure patterns, with 92% failing at the femoral neck.
- All prosthetic femurs still withstood ~6.2× body weight — exceeding estimated in vivo peak loads (~1.64× BW).
- Prosthesis positioning (neutral vs valgus) had no significant effect on biomechanical outcomes.
- Implant design preserved more metaphyseal bone stock than total hip replacement, possibly explaining the smaller load reduction compared to other short-stem prostheses.
- The press-fit cobalt–chromium design with conical stem allowed full contact and stress distribution over the femoral head/neck.
- Authors conclude the device has adequate immediate biomechanical strength for clinical use, though long-term in vivo studies are needed.

In Marshall 2022 et al., on delayed and non-union risk, what was the **strongest predictor** of delayed or non-union in canine fractures?
🔍 Key Findings
- Delayed union occurred in 13.9% of fractures; non-union in 4.6%; mal-union in 0.7%
- Major implant failure increased odds of delayed or non-union by 12.9×
- Surgical site infection increased risk 3.2×; bone grafting (any type) was also associated (OR 3.3)
- Comminuted fractures had 4.2× greater odds of delayed or non-union
- Older age increased risk, with odds increasing by 21% per year
- Radius and ulna fractures in toy breeds were not high risk, contrary to historical belief
- Most non-unions required revision surgery with rhBMP-2 or autograft to achieve union
- Ilium fractures showed 0% delayed/non-union — possibly due to robust muscle envelope

In Niida 2024 et al., on surgical residents and TPLO time, what data did the study provide on complication rates?
🔍 Key Findings
- Resident involvement significantly increased TPLO surgery duration compared to cases performed by faculty surgeons (FS)-only. Residents required 54% more surgery time (GLSM, 153 min) than FS-only cases (GLSM, 99 min), representing a 1.54-fold increase.
- The study did not report on short-term complication rates. No conclusions can be drawn from this source regarding complications between resident and faculty groups.
- Bone plate contouring was not evaluated. The source does not provide data regarding contouring frequency or its comparison between groups.
- Surgery duration significantly decreased after the first year of residency, but remained stable between second- and third-year residents. This was largely due to shorter tibial osteotomy durations, while arthroscopy times remained unchanged across residency years.
- Meniscal treatment was performed in 80% of cases, and it was associated with increased surgical duration, but the study did not compare the frequency of medial meniscal release between resident and faculty cases.
- The study did not evaluate osteotomy healing or revision surgery. Cases requiring immediate reoperation were excluded.
- Bone union outcomes were not assessed at 8 weeks or any other time point.
- The study concludes that resident participation significantly prolongs surgical time, but no data are provided regarding the effect on short-term clinical outcomes.

In Dickerson 2023 et al., on surgical outcomes in hepatic abscessation, which surgical intervention was most commonly performed?
🔍 Key Findings
- Liver lobectomy was the most common treatment (27/36 dogs), with multiple lobes removed in ~1/3 of cases.
- Septic peritonitis was present in 21/23 sampled dogs, making it a frequent complication.
- Perioperative complications occurred in 21/36 dogs, including aspiration pneumonia, pancreatitis, and acute kidney injury.
- Intraoperative hypotension was common (32/36), often requiring vasopressors or colloids.
- Mortality prior to discharge was 21% (8/38), with deaths related to sepsis, aspiration pneumonia, and multi-organ dysfunction.
- Median survival time was 638 days in dogs surviving to discharge.
- No recurrence of hepatic abscessation was observed in the surviving population.
- E. coli and Clostridium spp. were the most commonly cultured organisms, often as single-agent infections.

In Jeong 2025 et al., on contoured saw guide vs jig, what best describes *medial cortical damage* outcomes in bone models?
🔍 Key Findings
- TPLO with the contoured saw guide achieved more accurate osteotomy angles for both inclination and torsion in bone models and cadaveric limbs (p < .05).
- Medial cortical damage was significantly lower with the contoured guide (247 vs. 1866 pixels in bone models; p < .001).
- No significant difference in eccentricity (distance between actual and intended osteotomy center) was found between groups.
- Postoperative tibial plateau angle (TPA) was similar between groups (6.4° vs. 7.6°; p = .15), though both were slightly higher than the target of 6°.
- Deviation in medial mechanical proximal tibial angle (mMPTA) showed no significant group difference; valgus deformity occurred in both.
- Osteotomy and device application times were similar between the contoured guide and jig-assisted TPLO.
- The contoured guide eliminated the need for proximal jig pin, potentially reducing intra-articular pin risk.
- The guide's multiple pin fixation system improved stability and alignment, supporting safer osteotomy on curved tibial surfaces.

In Vandekerckhove 2024 et al., what force was required for 90% of hips to reach at least 90% of LImax?
🔍 Key Findings Summary
- Used VMBDmD to quantify hip laxity under increasing force in cadaveric dogs (n=34).
- 90% of hips reached ≥90% of LImax at 95.32 N, defining this force as sufficient for subluxation.
- LImax was not significantly influenced by osteoarthritis, weight, sex, or limb side.
- Position of device (lever length) influenced rate of laxity acquisition, not final LImax.
- LI curves were repeatable across 5 sessions, indicating elastic—not plastic—deformation.

In Barrett 2023 et al., on complication grading systems, what percentage of complications were graded as **Grade 3** using the aCD system?
🔍 Key Findings
- Cook system had good reliability across all cases (ICC = 0.848), even when complications, sequelae, and failure-to-cure were included.
- aCD system had excellent reliability when excluding sequelae/failure-to-cure cases (ICC = 0.975) but only moderate reliability when including them (ICC = 0.620).
- Majority of complications (60–63%) were graded as Grade 3 in the aCD system, corresponding to surgical or anesthetic intervention.
- Cook system classified most cases (78–81%) as major complications.
- Assessors had difficulty distinguishing sequelae from Grade 1 complications, and failure-to-cure from Grades 1–2, reducing aCD reliability.
- The aCD system offers more resolution (5 grades vs. 3) and less subjectivity through objective definitions.
- Novel terminology (e.g., sequelae, failure to cure) in the aCD system may hinder its uptake without proper training.
- Reclassifying expected events (e.g., swelling, bruising) as sequelae could significantly reduce reported complication rates in other studies.

In Shetler 2022 et al., on radial head OCD, which of the following was reported at the 5-month postoperative follow-up?
🔍 Key Findings
- Bilateral radial head OCD lesions were identified in a 6-month-old English Bulldog with elbow lameness.
- Medial arthroscopic portals allowed only partial visualization of radial head lesions, insufficient for treatment.
- Lateral arthroscopy portals provided excellent access for fragment removal and abrasion arthroplasty.
- Histopathology confirmed OCD, showing cartilage degeneration and retained cartilaginous cores.
- Dog showed complete resolution of lameness and no elbow pain at 5 months post-op.
- Lesions were caudolateral on the radial head, with discoid elevation of cartilage and clefts.
- Lateral approach avoids major neurovascular structures, reducing iatrogenic risk.
- The authors suggest lateral elbow arthroscopy may have broader indications, including for medial compartment disease or synovial biopsies.
