Plain-English summary
A group of 14 cats with sacroiliac luxation (a dislocation in the pelvis) underwent a minimally invasive surgery using special screws to fix the joint. After the procedure, most of the cats showed significant improvement, with 10 out of 11 owners reporting they were very satisfied with the results. While the screws worked well for most cats, some had issues with loosening when both sides were treated. Overall, this method proved to be safe and effective for fixing this type of injury in cats.

Abstract
OBJECTIVE:  To describe percutaneous fluoroscopy-guided placement of self-drilling, self-tapping, 3.0 mm cannulated headless compression screws (HCS) for surgical reduction of sacroiliac luxation (SIL) in cats, and to document clinical outcome. MATERIALS AND METHODS:  Medical records of cats with SIL, managed by percutaneous fluoroscopy-guided placement of a 3.0 mm HCS, were reviewed. Short-term outcome was assessed by clinical examination and radiographs. Long-term outcome was assessed using an owner questionnaire. RESULTS:  A total of 14 cats, with 17 SIL (11 unilateral and 3 bilateral), were included. Mean postoperative sacroiliac joint reduction was 85%, median sacral purchase was 63% for unilateral and 38% for bilateral HCS, and pelvic canal diameter ratio and hemipelvic canal width ratio were satisfactory in all cases. At follow-up, all cats exhibited satisfactory clinical improvement. Radiographic assessment revealed no implant-related complications of the unilateral HCS; however, screw loosening was observed in 3/6 of bilateral HCS. Owner satisfaction was good, with 10/11 of owners being very satisfied and 1/11 being satisfied. CLINICAL SIGNIFICANCE:  Percutaneous fluoroscopy-guided placement of a 3.0 mm HCS is a safe and effective method for unilateral surgical reduction of SIL in cats. Further studies are needed to establish the most appropriate procedure to treat bilateral SIL.
