🔍 Key Findings

• HIF-affected dogs had significantly greater angle A and B, indicating increased axial articular angulation of the medial and lateral humeral condyle (p < .001).
• Vertical condylar height (lengths a and b) was significantly greater in HIF-affected dogs compared to controls (p = .007 and p < .001 respectively).
• Angle G (dorsal plane medial condyle angle) was also significantly greater in HIF-affected dogs, suggesting altered medial humeral morphology (p < .001).
• The angle between axial surfaces (A–B angle) was significantly more acute in HIF dogs (107.4° vs. 114.2°, p < .001), suggesting potential for increased shear force.
• Springer Spaniels with HIF showed significantly greater angulation and vertical height than unaffected Springer controls (p < .001 to .007 across variables).
• Morphological differences persisted across non-spaniel breeds, reinforcing that altered condylar geometry is not breed-restricted.
• Authors propose that greater condylar angulation contributes to shear stress, orthogonal to the fissure, possibly contributing to HIF pathogenesis.
• These morphologic alterations could inform future screening or preventive strategies, and may explain variable surgical outcomes and implant failure.

🔍 Key Findings

• Postoperative Protein C (PC) activity increased in 78.7% of dogs, and was significantly higher in dogs with excellent clinical outcomes.
• Complete acute shunt occlusion resulted in higher postoperative PC activity (96.3%) and better ultimate clinical outcomes than incomplete occlusion.
• Preoperative PC was not predictive of clinical status, but postoperative PC was associated with improved outcomes.
• Standard biochemical markers (HCT, MCV, ALB, BUN) also improved postoperatively, especially in dogs with excellent clinical outcomes.
• Dogs requiring a second procedure had significantly lower postoperative PC (43.5%) than those not requiring further intervention (78.5%).
• Repeat procedures improved PC and BUN values, with PC increasing significantly after second intervention (to 69.8%).
• PC normalization (within reference interval) occurred in 87.5% of dogs with excellent clinical status, compared to only 12.5% in those with poor status.
• Clinical outcome classification (excellent/fair/poor) correlated with biochemical normalization and lack of need for diet/medications.

🔍 Key Findings

• CCT surgery was performed in 80 dogs (89 limbs) across five referral centers in a retrospective cohort study evaluating surgical treatment outcomes.
• Tendon repair with tarsocrural immobilization was the most common treatment (51.7%), followed by pantarsal arthrodesis (36%) and immobilization without repair (12.3%).
• The three-loop pulley was the most frequently used tendon repair suture pattern (41.3%) among repaired tendons.
• Overall complication rates did not differ significantly between tendon repair (56.5%) and pantarsal arthrodesis (42.8%) (p = .543).
• Catastrophic complications were significantly higher after tendon repair with immobilization (26.1%) compared with pantarsal arthrodesis (0%) (p = .005).
• Temporary tarsocrural immobilization (with or without tendon repair) was associated with higher revision surgery risk than pantarsal arthrodesis.
• Median referral follow-up time was 10 weeks (range 6–256 weeks).
• Long-term owner outcomes (LOAD questionnaire) showed no difference in mildly affected dogs among surgical groups (p = .493).

🔍 Key Findings

• Temporary transarticular locking plates successfully immobilized the stifle joint for protection of primary repairs (e.g., ligament reconstruction or articular fracture fixation) in dogs and cats.
• 15 stifle joints in 13 patients met inclusion criteria (9 dogs, 4 cats) treated for injuries such as patellar fracture, patellar ligament rupture, stifle luxation, and femoral condylar fractures.
• The plate was contoured along the medial distal femur and proximal tibia, immobilizing the joint at 135–145° extension with at least three screws in each bone segment.
• Implant removal occurred at a median of 58 days (range 27–96), aligning with the planned ~6-week immobilization period intended to protect repair while limiting cartilage damage.
• No intraoperative complications were reported, and all animals were able to ambulate comfortably postoperatively.
• One major complication (plate breakage at 19 days) required early removal and temporary orthotic support.
• Four minor complications involved plate breakage occurring after the recommended removal time, often related to delayed follow-up appointments.
• Respecting the planned 6-week implant removal is important to prevent implant failure, and dedicated anatomically designed plates may further improve technique reliability.

🔍 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.

🔍 Key Findings

• Intraoral approach (IOA) reduced surgical time compared to lateral orbitotomy (median: 42.0 vs 65.7 minutes, p = .005)
• Ease of closure (Stage III) was better with IOA (p < .001), though gland removal (Stage II) was easier with LOA (p = .039)
• Complete gland removal was achieved in 8/10 IOA vs 10/10 LOA cases in cadaveric study
• All 3 clinical cases had uneventful recoveries post-IOA, including one carcinoma, with no intra- or short-term postoperative complications
• LOA had superior surgical exposure, but was more invasive and time-consuming
• IOA posed greater difficulty in complete gland removal in brachycephalic dogs, with remnant tissue noted in 2/10 cadavers
• IOA avoids osteotomy, reducing potential complications like delayed union and postoperative pain
• Cosmetic outcomes and healing were better with IOA, and no E-collar was required postoperatively

🔍 Key Findings

50 dogs underwent bilateral anal sacculectomy using a modified closed technique.
Intraoperative anal sac perforation occurred in 5 dogs (10%), with no postoperative complications in those dogs.
Postoperative complications (43 dogs with follow-up):

• Grade 1 (e.g., scooting, inappropriate defecation): 14/43 (32%)
• Grade 2 (medical treatment needed): 2/43 (5%)
• Grade 3B (revision surgery): 2/43 (5%)

93% of grade 1 and 100% of grade 2–3B complications resolved by two weeks postop.
Technique highlights: direct duct tracking, no anal sac packing, minimal dissection.

🔍 Key Findings

• LVSG was successfully performed in 9/10 cadavers and both live cats, demonstrating procedural feasibility.
• Mean stomach resected was 27.6% of total weight in cadavers, with no leaks in 8/8 tested or either live patient.
• Mean surgical time: 110.4 min (cadavers) and 115 min (live cats); no intra- or postoperative complications observed.
• Stenosis near the incisura occurred in 2 cadavers; attributed to staple placement too close to the lesser curvature.
• 3D printed cannulas (3DPCs) improved ergonomics and were used in 6/10 cadavers and both live procedures.
• Live cats lost 21–24% body weight over 3 months, with full return to pre-surgical BCS and no GI complications.
• Orogastric tube and proper tensioning were critical in preventing gastric stenosis during staple placement.
• No reinforcement or oversew was used on the staple line; TriStaple cartridges provided reliable closure.

🔍 Key Findings

• 3D-printed patient-specific guides (PSGs) improved tibial cut alignment in the frontal plane compared to generic guides (mean error 1.03° vs 2.41°, p = .036).
• All tibial cuts using PSGs were within 3° of target alignment, while 2/8 of the generic group were outliers.
• PSGs significantly improved sagittal alignment of both distal (p = .018) and cranial (p = .043) femoral cuts.
• No significant difference was found in varus-valgus femoral alignment or closing angle between PSG and generic guide groups.
• Tibial sagittal slope alignment was not significantly different between groups.
• PSGs provided better intraoperative usability, including improved visibility, no loosening, and ease of use.
• Femoral sizing and component fit were equivalent between PSGs and generic guides, ensuring proper prosthesis alignment.
• PSGs may offer training advantages for novice surgeons, especially in anatomically complex or deformed joints.

🔍 Key Findings

• Precontoured plates using 3D-printed femoral models achieved near-anatomic alignment in all cadaver limbs.
• Fracture reduction system (FRS) required significantly fewer fluoroscopy images than intramedullary pin (IMP) methods (7 vs 26, P = .001).
• Despite longer surgical time (43 vs 29 minutes, P = .011), FRS showed equally accurate or better alignment compared to IMP.
• Femoral length, frontal, sagittal, and axial alignment were all within near-anatomic thresholds (<10 mm or <5° deviation) in both groups.
• FRS was associated with more consistent length maintenance, with IMP showing a median shortening of 2.3 mm (P = .03).
• Axial plane deviation was statistically different in the FRS group (P = .04), but still clinically acceptable.
• Study highlights potential for custom 3D-printed guides to reduce radiation exposure and improve precision in MIPO procedures.
• Authors caution that FRS was time-consuming and cumbersome, suggesting design refinements needed for clinical use.
