🔍 Key Findings

• TPA decreased significantly from preoperative to follow-up (mean 5.89°; p < 0.001), and from immediate postoperative to follow-up (mean 2.2°; p = 0.018)
• Use of tension band in addition to K-wires did not significantly improve TPA reduction compared to K-wires alone
• Cranial K-wire positioning may attenuate growth at the cranial tibial physis, allowing relative caudal growth to reduce TPA over time
• Dynamic TPA reduction may reduce risk of cranial cruciate ligament rupture even when initial TPA is high
• Small breeds (e.g., French Bulldogs) were overrepresented; further research is needed in larger breeds with more growth potential
• Surgical reduction is difficult, but perfect alignment may not be essential if TPA reduces postoperatively
• Radiographic TPA measurement was reliably performed with low interobserver variability
• K-wire removal at 3–8 weeks may facilitate continued growth in growing dogs

🔍 Key Findings

• BLIS (bupivacaine liposome injectable solution) provided equivalent analgesia to fentanyl CRI based on CMPS-SF scores at all time points except 6h, where BLIS was superior
• Fewer adverse effects (nausea, vomiting, sedation) were noted in the BLIS group
• BLIS dogs ate sooner postoperatively (median 6h vs 9h in control)
• Sedation occurred in 2/20 dogs in BLIS group vs 10/20 in fentanyl group
• Vomiting occurred in 0/20 BLIS dogs vs 4/20 in fentanyl group
• Rescue analgesia rates were similar (5 BLIS vs 4 fentanyl group), confirming noninferiority
• Owner-reported VAS scores were lower for BLIS on day 1 a.m. and p.m. despite variability
• Results suggest BLIS could reduce opioid reliance post-amputation

🔍 Key Findings

Incidence of BFX lateral bolt stem breakage: 2.95% (13 dogs, 14 stems)

Implant factors:

• 13/14 were BFX lateral bolt stems (sizes #5–7)
• +9 necks used in 5/11 of 17 mm heads
• 10/14 stems undersized based on radiographs
• 10/13 dogs exceeded weight limits for implanted stem size

Malalignment:

• 10/14 had varus alignment (median 3.9°)
• 8/14 had insufficient proximodistal seating

Breakage site: Proximolateral shoulder in all cases

Revision outcomes:

• 11 revised (7 CFX, 3 larger BFX, 1 collared)
• 9/10 revised dogs regained full function
• Complications: 1 rebreakage, 1 periprosthetic fracture, 1 fixation failure

Histopathology:

• Electron microscopy showed fatigue striations and incomplete bead fusion

Conclusion: Avoid small BFX lateral bolt stems if undersized or if long necks required; use weight guidelines to prevent fatigue failure.

🔍 Key Findings

• TPLO mRUST scoring showed improved inter-rater reliability (ICC = 0.56) compared to subjective evaluation (Kappa = 0.33).
• Intra-rater reliability was similar for both methods (TPLO mRUST: 0.73, subjective: 0.72).
• TPLO mRUST scores ≥10/12 strongly correlated with radiographic union, as subjectively assessed (99% agreement).
• No significant difference in healing between first and second TPLO sides (P = .09), countering assumptions about load-bearing impact.
• Higher initial lameness scores and younger age were associated with higher TPLO mRUST scores, suggesting more robust healing in those groups.
• Postoperative complications were linked to lower TPLO mRUST scores, indicating impaired healing.
• Medial cortex was excluded from scoring due to plate obstruction, validating use of only 3 cortices for scoring.
• The TPLO mRUST system may standardize healing assessment, reducing subjective bias across specialties.

🔍 Key Findings

• CESF with distraction osteogenesis restored elbow congruity and normalized aLDRA in skeletally immature dogs with PCDRP.
• Radial head subluxation was eliminated in all dogs, and elbow incongruity reduced significantly (from 6.1 mm to 0.3 mm, p <.01).
• Mean radial lengthening of 22.6 mm (∼11% of normal length) was achieved, but only 80% of recorded distraction translated to length gain.
• Major complications occurred in 2/12 dogs: one with permanent carpal contracture, one with radial fracture at wire tract.
• Minor complications (e.g., carpal pain, restricted extension, synostosis, pin tract issues) were noted in 10/12 dogs but generally resolved.
• Owner surveys (8/12 dogs) reported good to excellent long-term function, even up to 6 years post-op.
• Radial valgus deformities were moderate (mean 15°) and less severe than deformities from ulnar physeal closure.
• Surgical strategy included staged distraction, with radial or combined radius/ulna distraction guided by fluoroscopy and adjusted per case.

🔍 Key Findings

• All dogs (11/11) showed improved radiohumeral articulation postoperatively, confirmed arthroscopically.
• Median shortening: radioulnar (3.2 mm), humeroradial (1.8 mm), humeroulnar (1.2 mm).
• Median lameness score improved from 2/4 to 1/4 by final follow-up.
• Bone healing achieved in a median of 8 weeks (range: 4–14 weeks).
• No major complications; minor issues included 1 screw loosening and 1 superficial infection.
• Subjective function was graded full in 4 dogs, acceptable in 7.
• Arthroscopy enabled accurate dynamic joint assessment, preferred over static radiographs.
• Use of both orthopedic wire and plating provided secure fixation and improved outcomes.

🔍 Key Findings

• Accurate femoral isometric placement was achieved in 63% of cases, significantly more with SwiveLock (78.6%) than FASTak (38.9%).
• Inaccurate placement was associated with increased internal tibial rotation at follow-up (p = .009), suggesting potential implant failure.
• Pivot shift grade improved in 90.9% of stifles postoperatively, regardless of implant positioning accuracy.
• SwiveLock implants had a faster learning curve and higher placement accuracy than FASTak.
• Higher patient weight was linked to more accurate implant placement (p = .012), likely due to easier anatomical landmark identification.
• No correlation found between implant type or positioning accuracy and final pivot shift grade at 6 weeks.
• Minor and major complications were low and not significantly different between implant types.
• A simplified 2-grade pivot shift system was proposed for clinical use (Grade 1: glide, Grade 2: clunk), aiding intraoperative decision-making.

🔍 Key Findings

• Mitral valve plasty (MVP) in dogs with MMVD significantly reduced regurgitant volume and fraction, and normalized LA:Ao ratio, indicating reversal of volume overload.
• MVP altered mitral valve geometry, with reduced annular dimensions and increased coaptation length, enhancing valve competence.
• Postoperative LA:Ao ratio dropped from 2.2 to 1.2, consistent with improved left atrial pressure and size.
• Forward stroke volume index and cardiac index increased at 3 months, reflecting improved hemodynamic function despite reduced fractional shortening.
• Three dogs (3.9%) died postoperatively, highlighting a 96.1% survival rate within 3 months.
• The repair technique involved artificial chordal replacement and annuloplasty; no cleft closure or leaflet suturing was used.
• Color Doppler echocardiography confirmed substantial reduction in mitral regurgitation postoperatively in most dogs.

🔍 Key Findings

• Zurich mini-cementless THA was successful in 9/10 hips in dogs <4 kg, with no lameness at 52 weeks in completed cases.
• Helsinki Chronic Pain Index significantly improved from a mean of 19.8 to 2.3 at 52 weeks (p = 0.0141).
• Fluoroscopy improved implant positioning, especially in LCPD and HD cases, aiding in accurate reaming and alignment.
• Intraoperative complications occurred in 2/10 cases, including acetabular fractures; one case required discontinuation.
• Prophylactic bicortical screws and reinforcement plates were used in cases with rotational instability or cortical compromise and were effective in preventing loosening/fractures.
• Medial patellar luxation improved postoperatively in one dog, though recurrence was noted later without surgical correction.
• No stem or implant loosening or fracture occurred over a mean follow-up of 24.4 months.
• CT is recommended in preoperative planning, particularly in luxoid hip dysplasia cases with uncertain bone stock.

🔍 Key Findings

• Double pelvic osteotomy (DPO) significantly decreases dorsal acetabular rim angle (DARA), confirming improved acetabular ventroversion and femoral head coverage in dysplastic hips.
• The achieved acetabular ventroversion is consistently less than the plate’s predetermined angle, indicating predictable loss of rotation during DPO.
• Median reduction in DARA was 23.4°, 16.7°, and 15° with 30°, 25°, and 20° plates respectively, demonstrating that larger plates produce greater rotation but still less than intended.
• Actual ventroversion achieved was ~5–8° less than the plate angle, with median losses of 6.6°, 8.3°, and 5° for 30°, 25°, and 20° plates.
• Postoperative DARA decreased from ~16–18° preoperatively to approximately −4°, aligning with recommended postoperative acetabular slope targets.
• Postoperative DARA remained stable on short-term (~48 days) and long-term (~386 days) CT follow-up, suggesting minimal remodeling after DPO.
• Most acetabular rotation (~88%) occurs at the pelvic symphysis rather than through iliac torsion, explaining partial loss of rotation relative to plate angle.
• CT-measured DARA provides a reliable surgical planning metric and may improve implant angle selection for DPO procedures.
