🔍 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

• Modified subdural shunt (SDS) placement was adapted from prior techniques using a hemilaminectomy approach and no suturing of the dura or shunt.
• Dogs receiving SDS had significantly better long-term outcomes (85.7% improved) compared to those with durotomy alone (41.7%).
• Recurrence rate was lower in the SDS group (14.3%) than control (41.7%), though not statistically significant.
• Most recurrences occurred in Pugs (5/7), suggesting a breed predisposition.
• Shunt size was limited to 25% of spinal cord diameter, typically 3–3.5 Fr.
• CSF flow through the shunt was confirmed intraoperatively, supporting the role of SDS in maintaining flow and possibly preventing recurrence.
• Immediate postoperative outcomes were not different between groups (≈42% deteriorated), but long-term recovery was better with SDS.
• Steroid use pre-surgery did not correlate with improved outcome; fewer SDS dogs received steroids pre-op.

🔍 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

• 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

🔍 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.

🔍 Key Findings

Study focus: Outcomes of cannulated screw fixation in unicondylar humeral condylar fractures (UHCF) in dogs.
Clinical union rate: 89%
Overall complication rate: 36%

• Major complication: Most common was screw breakage

Significant risk factor for screw breakage:

• Body weight >20 kg (statistically significant)

Breed distribution:

• Spaniels, especially English Springer Spaniels, were most common

No mention of plate augmentation as standard in this cohort

🔍 Key Findings Summary

• 20 shoulders from 11 medium-to-large breed dogs evaluated
• Lateral portals used: middle arthroscopic, caudal instrument, cranial egress
• Musculotendinous lesions unavoidable, but small (18G needle); seen in deltoideus (90%), infraspinatus, teres minor, etc.
• Neurovascular safety:
  • Caudal portal was closest to axillary artery/nerve branches (as close as 7 mm)
  • Only 2/20 shoulders (10%) had omobrachial vein penetrated
• Cartilage injuries (IACI) occurred in 65%, primarily minor linear defects; use of guarded cannulas and distractors suggested for minimization
• Supports overall safety of lateral shoulder arthroscopy with portal placement awareness

🔍 Key Findings Summary

• 48 dogs (60 stifles) underwent custom 3D-printed TRP implantation for patellar luxation
• 24 treated with TRP alone; 36 with additional procedures (e.g., DFO, TTT)
• Success rate: 59/60 corrected patellar tracking
• Functional outcome: 57/60 full function, 2 acceptable, 1 unacceptable
• Complication rate: 3 total (2 minor, 1 major recurrence)
• TRP spares cartilage unlike trochleoplasty, offering implant-based ridge augmentation
• No implant loosening or infection observed

🔍 Key Findings

• Arthroscopic-assisted hip toggle stabilization (AA-HTS) was successfully completed in all 14 feline cadaver joints.
• Femoral and acetabular tunnel creation was feasible in all cases, though femoral tunnel placement had a higher rate of deviations.
• Intraoperative complications occurred in 5/14 joints, mostly related to femoral tunnel creation and toggle lodging.
• Minor articular cartilage injury (<10% total cartilage area) occurred in 10/14 joints, but no injury to neurovascular or intrapelvic structures.
• Thirteen surgical technique deviations (8 major, 5 minor) were identified in 7 joints, all involving the femoral tunnel.
• Toggle passage through the femoral tunnel was the most challenging step, being mildly difficult in 6 joints.
• Postoperative CT and gross dissection confirmed all toggles and buttons were in correct position, without damage to major surrounding structures.
• No deviations, complications, or cartilage injuries occurred in the last 4 joints, suggesting a learning curve effect.

🔍 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
