Jourdain et al: Fluoroscopically-assisted closed reduction and percutaneous fixation of sacroiliac luxations in cats using 2.4 mm headless cannulated compression screws: Description, evaluation and clinical outcome
Veterinary Surgery 4, 2024

🔍 Key Findings

  • Minimally invasive fluoroscopic technique yielded median reduction of 94.1% immediately postoperative.
  • Screw purchase ≥60% in sacral body achieved in 82% of cases, with median purchase of 73.3%.
  • One screw exited caudally; no dorsal, ventral, or cranial exits reported.
  • At 7-week follow-up, reduction and purchase slightly declined but remained effective (p = .008 and p = .013).
  • No screw loosening observed, even in suboptimal reductions or purchases.
  • Pelvic canal width and symmetry (PCDR and HCWR) were restored and maintained.
  • Excellent long-term function: FMPI ≥0.98 in 9 of 10 cats; owners reported 10/10 satisfaction.
  • Fluoroscopy enabled accurate screw placement and minimized tissue trauma, contributing to rapid recovery.

Multiple Choice Questions on this study

In Jourdain 2024 et al., on fluoroscopic fixation of feline SIL, what percentage of screws had ≥60% purchase within the sacral body?

A. 52%
B. 64%
C. 71%
D. 82%
E. 95%

Answer: 82%

Explanation: 14 of 17 screw placements (82%) had ≥60% purchase within the sacral body, a threshold for biomechanical stability.
In Jourdain 2024 et al., on fluoroscopic fixation of feline SIL, how many screws exited the sacral body postoperatively?

A. 0
B. 1
C. 2
D. 3
E. 5

Answer: 1

Explanation: Only one screw exited caudally; no cranial, dorsal, or ventral exits were observed.
In Jourdain 2024 et al., on fluoroscopic fixation of feline SIL, what was the median postoperative reduction immediately after surgery?

A. 73.3%
B. 78.2%
C. 88.3%
D. 94.1%
E. 98.0%

Answer: 94.1%

Explanation: The median sacroiliac reduction immediately after surgery was 94.1%, with 11 of 17 procedures achieving ≥90%.
In Jourdain 2024 et al., on fluoroscopic fixation of feline SIL, what tool enabled accurate screw guidance during surgery?

A. C-arm with targeting jig
B. K-wire and laser guide
C. Custom 3D-printed drill guide
D. C-arm fluoroscopy with cannulated guide wire navigation
E. Open reduction via dorsolateral approach

Answer: C-arm fluoroscopy with cannulated guide wire navigation

Explanation: The headless cannulated screws were placed with fluoroscopic guidance over a guide wire.
In Jourdain 2024 et al., on fluoroscopic fixation of feline SIL, what was the long-term owner-reported satisfaction outcome?

A. 80% good to excellent
B. No cats recovered fully
C. One-third required reoperation
D. All cats reported poor function
E. All but one scored 10/10

Answer: All but one scored 10/10

Explanation: Owner-reported outcomes were excellent; all cats scored 10/10 except one that had prior amputation.
