Adrian et al: Use of Locking Plates Fixed with Cortical Screws for Pelvic Fracture Repair in 20 Cats
Veterinary and Comparative Orthopedics and Traumatology 1, 2024

🔍 Key Findings

  • 20 cats with pelvic fractures treated with SOP plates and cortical screws
  • Full function reported in all patients per FMPI follow-up
  • Screw loosening in 3/20 SOP cases; implant removal in 3 cats
  • Median sacral index decrease at follow-up: 5.7%; mostly mild narrowing
  • Complications: 5 major (3 SOP removals, 2 trochanter osteotomy issues); 20 minor
  • SOP plate shown feasible even in challenging configurations; good functional outcomes

Multiple Choice Questions on this study

In Adrian 2024 et al., on feline pelvic fracture stabilization, what was a suggested strategy to reduce screw pullout in SOP constructs?

A. Use monocortical screws only
B. Avoid fixing to the sacrum
C. Apply shorter plates to reduce stiffness
D. Use longer plates with more bicortical screws
E. Place plates medially to avoid lateral strain

Answer: Use longer plates with more bicortical screws

Explanation: Failure occurred in short plate cases; longer plates improved outcomes.
In Adrian 2024 et al., on feline pelvic fracture stabilization, what was the primary complication encountered postoperatively with SOP plate use?

A. Implant migration
B. Trochanteric fracture
C. Screw loosening
D. Sciatic neuritis
E. Megacolon

Answer: Screw loosening

Explanation: Screw loosening was observed in 3 cats and was the most frequent implant-related issue.
In Adrian 2024 et al., on feline pelvic fracture stabilization, what was the most commonly reported outcome according to the FMPI?

A. Mild pain with acceptable function
B. Moderate discomfort with fair function
C. Partial recovery with limitations
D. Full function with minimal or no pain
E. Significant functional limitation requiring revision

Answer: Full function with minimal or no pain

Explanation: FMPI results showed all 18 cats with follow-up had full function, with low pain scores.
In Adrian 2024 et al., on feline pelvic fracture stabilization, how did the median sacral index change from immediate postop to follow-up?

A. Increased by >10%
B. Increased slightly (~2%)
C. No change observed
D. Decreased by ~5.7%
E. Decreased by >20%

Answer: Decreased by ~5.7%

Explanation: Pelvic canal narrowing led to a median sacral index decrease of 5.7% at follow-up.
In Adrian 2024 et al., on feline pelvic fracture stabilization, what was the most common grade of pelvic canal narrowing at follow-up?

A. Severe narrowing (>30%)
B. Moderate narrowing (10–30%)
C. Mild narrowing (<10%)
D. No narrowing detected
E. Canal widening observed in most cases

Answer: Mild narrowing (<10%)

Explanation: At follow-up, 12 of 16 cats with narrowing showed mild change in sacral index.
