🔍 Key Findings Summary

• The lateral approach via scapular osteotomy allowed safe access to the T1-2 foramen in a French Bulldog with foraminal disc extrusion.
• A mini-hemilaminectomy was performed, preserving articular facets.
• The dog had no neurologic deficits postoperatively, returned to ambulation within 24 hours, and was discharged in 3 days.
• At 10 months, CT confirmed excellent scapular healing and no recurrence.
• Double 2.4-mm locking plates provided stable fixation across the scapular spine.
• The technique avoided thoracic entry or dorsal spine dissection, suggesting a less invasive alternative for select T1-2 foraminal cases.

🔍 Key Findings

• Spinal stabilization with 3D-printed patient-specific drill guides (3D-PSGs) was safe, with no immediate perioperative complications reported.
• 84% of pedicle screws were optimally placed, and only 0.5% breached the spinal canal, reflecting high placement accuracy.
• 80% of dogs experienced no neurologic deterioration postoperatively, indicating reliable short-term safety.
• 3D-PSGs were accurate and reproducible, even across multiple institutions and surgeons.
• Mid-term outcomes were favorable: all dogs were ambulatory, and 90% had static or improved neurologic signs.
• 7 of 10 mid-term follow-ups showed abnormal gait, though owners rated lifestyle ≥3/5, suggesting acceptable function.
• 3D-printed guides enabled precise pedicle screw placement in deformed vertebrae, expanding options in small breeds.
• One dog suffered a T4 spinous process fracture due to overextension of PMMA cement, emphasizing the need for cement placement caution.

🔍 Key Findings

• Supracutaneous locking plates (SLPs) were successfully used to manage 33 diaphyseal fractures (radial–ulnar and tibial) in 30 cats and dogs.
• Median fracture healing time was 50.5 days (range: 27–88), with most patients regaining limb use within days postoperatively.
• CT-based metrics (callus area, HU, and 3D bone volume) increased significantly during healing (p < 0.05), validating CT as a quantitative tool for assessing healing.
• Complications were minimal: minor in 15/33 (e.g., screw tract discharge, edema), and major in 3/33 (e.g., implant failure, delayed union, nonunion).
• Minimally invasive osteosynthesis required longer surgery times than closed reduction (p < 0.05), but both techniques were viable.
• SLPs enabled successful bilateral fracture management without inter-plate interference due to their compact design.
• Screw orientation challenges were noted in cats, especially with cranial application to the radius due to narrow anatomy.
• Polyaxial locking screws were used safely and did not dislodge, allowing for angular insertion (≤10°) to avoid neurovascular structures.

🔍 Key Findings

• Ilio-sacral lymphadenectomy had the highest complication rates: intraoperative (7%) and postoperative (41%)
• Axillary lymphadenectomy showed the lowest complication rates: intraoperative (1%) and postoperative (16%)
• Enlarged or metastatic lymph nodes were significantly associated with intraoperative complications (p = .030)
• Postoperative complications were mostly minor (Grade 1) and self-limiting (seromas, edema)
• Medial retropharyngeal lymphadenectomy had intermediate complication rates: postoperative complications in 26%
• No significant predictors retained significance in multivariate analysis
• Use of methylene blue was associated with fewer complications, although not statistically significant
• Complication rates did not result in mortality, and all were manageable; MST was 374 days

🔍 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.

🔍 Key Findings

• Feasibility study in 5 canine cadavers plus 1 clinical case (Chihuahua, 5.5 kg).
• Technique used two small approaches (caudal and craniolateral) connected with an epiperiosteal tunnel.
• Plates were precontoured on mirrored 3D-printed hemipelves to improve fit and reduce intraoperative bending.
• Cadaver outcomes: fracture gap <2 mm, step defect <1 mm, pelvic angulation <5°.
• Sciatic nerve injury was minimal: 1/5 cadavers had a mild indentation; others had no gross injury.
• Median total surgical time: ~46 minutes in cadavers; incisions ~5 cm.
• Clinical Chihuahua case: weight-bearing within 24 hrs, radiographic union at 3 months; one screw fractured but no adverse effect.
• Authors conclude: MIAF with 3D printing is feasible and accurate, but requires further evaluation before routine use.

🔍 Key Findings

Population: 9 dogs underwent revision of osteointegrated acetabular cups after total hip arthroplasty (THA)

Revision Indications:

• 7 luxations (5 ventral, 2 craniodorsal)
• 1 femoral stem fracture
• 1 aseptic stem loosening

Implants:

• 8 BFX cups, 1 Helica; all revised to BFX
• 7/9 required a larger cup than original

Cup removal: Required sectioning with a high-speed burr and modular osteotome; removal fragments extracted

Complications:

• 1 recurrent luxation
• 1 low-grade infection with possible metallic debris-associated osteolysis
• 2 femoral fissures managed intraoperatively

Outcomes:

• Good to excellent function in 6/6 dogs available at median 621 days
• Minimal complications with success in re-osteointegration of new cup

Clinical takeaway: Revision of stable, ingrown cups is feasible and offers an alternative to pelvic osteotomies; typically requires upsizing

🔍 Key Findings Summary

• 20 cats with pelvic fractures treated using locking plates with only cortical screws
• 28 fractures stabilized (ilium: 17, acetabulum: 6, ischium: 3, pubis: 2)
• Implants: Primarily 1.5/2.0 mm LCPs or String-of-Pearls plates
• Major complications in 2/20 cases (10%): sciatic entrapment, malunion requiring THA
• Minor complications in 2/20 cases (10%): plate impingement, transient lameness
• Clinical union in all cats by 8 weeks; all cats returned to full function
• Authors conclude cortical screws alone can provide adequate fixation in feline pelvic fractures if screw purchase and bone quality are sufficient

🔍 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.
