EXPRESS: FLUOROSCOPY-ASSISTED SINGLE CANNULATED SCREW PLACEMENT FOR STABILISATION OF BILATERAL SACROILIAC JOINT LUXATION IN SIX CATS: TECHNIQUE AND OUTCOME.

Fluoroscopy-assisted cannulated screw placement is effective for bilateral sacroiliac luxation stabilization in cats.

This retrospective case series describes fluoroscopy-assisted percutaneous cannulated screw placement (FAPPCS) for treating bilateral sacroiliac joint luxation in six cats. The technique involves fluoroscopic guidance for precise screw positioning without using a mechanical guide. Key measurements included percentage of reduction (PoR), pelvic canal width ratio (PCWR), and angle of deviation (AoD). Results demonstrated excellent joint reduction bilaterally (right: 96.2%±6.6%, left: 98.8%±2.9%) with minimal angle deviation (1.3°). Only one minor complication occurred—spontaneously resolving lameness. No major intraoperative complications were identified, including no cranial, ventral, or foraminal impingement. Long-term follow-up revealed excellent functional recovery in 5/6 cases and moderate recovery in 1/6. Recovery timelines were favorable: 16.6% fully recovered within one month, 50% between one and two months, and 33.3% required more than two months. Owner satisfaction regarding postoperative management and quality of life was good. The authors recommend targeting the sacral body center before reducing the ilium. FAPPCS represents a viable salvage procedure for bilateral sacroiliac luxation in feline patients.
