🔍 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

Internal fixation (IF) group (n=59):

• Complication rate: 20.3%
• Major complications: 15.3%
• Longer time to discharge if complications occurred (median: 12.5 weeks)

External skeletal fixation (ESF) group (n=36):

• Complication rate: 55.6% (p < .001 vs IF)
• Major complications: 52.8%
• Most common issue: pin tract morbidity

Multivariable analysis:

• Use of IF significantly reduced odds of complications (OR 0.23, p = .004)
• Use of post-op antibiotics associated with increased odds of complications (OR 3.53, p = .028)

Fixation choice influenced by age:

• Older puppies more likely to receive IF (OR 1.25 per week increase in age, p < .001)

Breed & fracture distribution:

• Common breeds: Labrador, Border Collie, Whippet
• Common fracture sites: middle and proximal third of tibia

🔍 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.

🔍 Key Findings

• 42% of dogs (33/78) treated with Arthrex 3.5 mm STS during TPLO developed radiographic TCTF
• TCTFs occurred exclusively distal to the osteotomy
• 14% of screws (36/250) distal to the osteotomy were associated with TCTFs
• 6% of dogs with TCTFs developed major complications (e.g., complete tibial fracture requiring surgical revision)
• Angulation of cortical STS screws, especially in the distal plate holes, was a key contributor to complications
• Locking screws were also involved, but cortical screws angled improperly were overrepresented in serious outcomes
• Revision recommendations included preemptive fixation for large TCTFs or angulated screw placements
• Use of non-self-tapping screws (NSTS) previously showed a <1% TCTF rate, supporting higher risk with STS

🔍 Key Findings

• MEFF occurred in 11.4% (10/88 elbows) following medial-to-lateral transcondylar screw placement in dogs with HIF.
• Screw size to condylar height ratio >41% significantly increased MEFF risk (P = .004, OR 1.52).
• MEFF was not recognized intraoperatively in 60% of cases and was only seen on follow-up or retrospective imaging review.
• Screw loosening was the most common complication (11.2%), observed both with and without MEFF.
• MEFF tended to increase the risk of screw loosening (P = .06), but was not statistically significant.
• Most MEFFs did not require treatment and healed radiographically by 14–17 weeks in monitored cases.
• Shaft screws were used in all MEFF cases, but shaft vs cortical design was not significantly associated with MEFF.
• The clinical impact of MEFF was minor in most cases, although long-term significance is unknown.

🔍 Key Findings

• Both free-hand probing (FHP) and 3D-printed guides (3DPG) enabled accurate spinal pin placement, with 87.5% vs 96.4% of pins graded as optimal (Grade I).
• 3DPGs had fewer intraoperative deviations (0/56 pins) compared to 6/56 with the FHP technique.
• No pins using either method fully breached the medial vertebral canal (Grade IIb) — a critical safety outcome.
• Pins placed using 3DPGs required less time overall (mean 2.6 min) than FHP (mean 4.5 min).
• FHP required specific experience and has a learning curve, whereas 3DPG use requires CAD software and 3D printing access.
• FHP had more lateral canal violations (Grade IIIa: 4/56 vs 0/56 for 3DPG), suggesting slightly less precision.
• Both techniques were safe, and all deviations were recognized and corrected intraoperatively.
• 3DPGs may offer practical advantages in clinical settings lacking surgical expertise, while FHP allows immediate intervention without 3D printing delay.

🔍 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
