🔍 Key Findings

• Fasting ammonia (FA) was the most specific test (100%) for confirming EHPSS closure postoperatively.
• Serum hyaluronic acid (SHA) and MEGX at 15 minutes post-lidocaine were the most sensitive tests (96.9% and 96.2%, respectively).
• SHA combined with MEGX T15, or with FA or postprandial serum bile acids (SBA), provided 100% sensitivity with good specificity (72.4–82.8%).
• SHA levels remained elevated in all dogs with persistent shunting, even when other tests were normal.
• Paired SBA had moderate sensitivity (90%) and variable specificity (89%).
• The L/MEGX test at 30 min was less useful than at 15 min for assessing closure.
• Traditional SBA testing showed reduced utility postoperatively; normal values did not rule out persistent shunting.
• Blood tests improved when combined, but imaging remains essential to definitively confirm EHPSS closure.

🔍 Key Findings Summary

• 22 dogs (36 shoulders) with shoulder OCD randomly assigned to COPLA scaffold (n=19) or Control (n=17) group
• At 6 months: Significantly fewer dogs in COPLA group had OA (14% vs. 67%; p = 0.019)
• At 1.5 years: OA prevalence increased in both groups with no significant difference (COPLA: 64%, Control: 60%)
• HCPI (pain index) increased significantly at 1 week post-op in COPLA dogs only (p = 0.001), but later normalized
• Static weight-bearing improved only in unilaterally operated COPLA limbs (p = 0.015)
• One dog in COPLA group had a fragment dislodge requiring arthroscopic removal
• Overall, COPLA scaffold may provide short-term benefit in OA reduction, but long-term outcomes were similar

🔍 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

• Proximal BODPUOs (closer to 26–28% of ulna length) resulted in greater increases in proximal ulna tilt postoperatively (up to 18°).
• Distal osteotomies (closer to 48–49%) yielded minimal change in ulna angle.
• Strong linear relationship between osteotomy location and change in angle; correlation coefficient = 0.73.
• Initial proximal ulna angle (IPUA) influences results—angles closer to 90° yielded greater changes.
• Craniocaudal osteotomy angle had minimal impact on tilt change after adjusting for location.
• Osteotomy length had no significant effect on change in angle.
• Prediction intervals showed wide individual variation in outcomes, especially with more proximal osteotomies.
• No increase in complications was associated with more proximal osteotomies, contrary to past assumptions.

🔍 Key Findings Summary

• Tactical harness use altered kinematics in all forelimb joints
• Elbow most affected: increased extension, internal rotation, abduction at walk and trot
• Carpus: reduced flexion, increased abduction at walk
• Shoulder: least affected, but showed reduced flexion and increased abduction during walk
• Only significant ROM increases:
  • Shoulder frontal plane (22%)
  • Elbow transverse plane (19%) at walk
• Results suggest potential functional limitations from harness use during duty

🔍 Key Findings

• Modified prepubic urethrostomy (mPPU) was effective for managing proximal urethral obstructions in male cats.
• All 8 cats regained voluntary urination within 24 hours postoperatively.
• Early urinary incontinence and peristomal dermatitis occurred in all cats but were self-limiting.
• Two cats (25%) required surgical revision due to stomal obstruction from weight gain and abdominal fat.
• No intraoperative complications were reported in any of the 8 cats.
• Follow-up (13–84 months) showed sustained urinary continence and owner satisfaction in all cases.
• The rectus abdominis muscle tunnel likely increased outflow resistance, minimizing persistent incontinence.
• Recurrent hematuria and dysuria occurred in 3 cats but were managed conservatively.

🔍 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 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

• Staphylectomy was linked to higher risk of complicated recovery than folded flap palatoplasty (OR = 59.29, p = .0002).
• Laryngeal collapse > Grade 2 was strongly associated with poor recovery (OR = 97.13, p < .0001).
• Longer general anesthesia duration increased the risk of complications (OR = 1.01 per min, p = .0051).
• Increasing age significantly raised the odds of perioperative complication (OR = 1.04 per month, p = .0113).
• History of aspiration pneumonia was only found in dogs with complications, though not in final model due to instability.
• Complicated recovery included >12 h O₂ therapy, tracheostomy, or death.
• FFP may reduce pharyngeal-laryngeal edema, possibly improving immediate outcomes.
• Bulldogs comprised 80% of population, with French Bulldogs most common (63%).
