Objectives A very limited safe anatomical window for transiliosacral implant placement exists in cats (<0·5 cm 2 ). Lag screw fixation requires multiple bilateral implants thus increasing the risk of iatrogenic trauma and implant interference. We describe a safe and effective method for bilateral sacroiliac fixation in cats using a single implant to minimise inadvertent iatrogenic damage to local structures and restore pelvic canal diameter. Materials and Methods Eight cats underwent surgical fixation for traumatic bilateral sacroiliac luxation using a single smooth intramedullary pin. The pin spanned both ilial wings and sacrum. Implants were applied using a Universal C‐guide. Pre‐ and postsurgery pelvic canal diameter ratios were calculated. Short‐term follow‐up was performed at 10 to 14 days postoperatively. Long‐term follow‐up was performed using the Feline Musculoskeletal Pain Index Questionnaire. Long‐term radiographic assessment was available in two cases. Results The technique achieved safe and accurate implant position with precise sacroiliac joint reduction. Pelvic canal diameter ratios were restored to normal in all cases. Rapid return to normal hind leg function and excellent long‐term clinical outcomes were achieved. Clinical Significance This technique offers a simple, safe, repeatable and affordable technique for treating bilateral sacroiliac luxations in the cat without the aid of fluoroscopy. The procedure can be performed using surgical tools and inventory readily available in general small animal practices.
