Investigation of the Effect of Screw Fixation of Sacroiliac Luxation on Pelvic Canal Width Ratio in Cats

The aim of this study was to evaluate the pre- and postoperative effects of screw stabilization on the inter-ilium distance, pelvic canal width, and hemipelvic canal ratios in cats that developed sacroiliac luxation as a result of trauma. The study included 18 cats of different breeds, sexes, ages, and weights that were diagnosed with sacroiliac luxation due to trauma and underwent surgical intervention at the Selcuk University Small Animal Hospital between 2023 and 2024. Clinical, hematological, and radiological examinations were performed. Following medical treatment and rehabilitation of the patients requiring stabilization before surgery, screw fixation was applied between the ilium and sacrum to stabilize the sacroiliac luxation. Among the 18 cases, 16.6% had bilateral sacroiliac luxation, 16.6% had sacroiliac luxation with an ilium fracture, 16.6% had sacroiliac luxation with an ischium fracture, 11.1% had sacroiliac luxation with a pubis fracture, 11.1% had sacroiliac luxation with both pubis and ischium fractures, 5.6% had sacroiliac luxation with an acetabulum fracture, 5.6% had sacroiliac luxation with both acetabulum and ilium fractures, 5.6% had sacroiliac luxation with both ilium and ischium fractures, 5.6% had sacroiliac luxation with pubis and ilium fractures accompanied by femoral head luxation, and 5.6% had sacroiliac luxation with pubis, ilium, ischium, and symphysis pelvis fractures. In 84% of the 18 cases diagnosed with sacroiliac luxation and treated surgically, the postoperative pelvic canal width ratio (PCWR) was found to be ≥1.1. No statistically significant difference was observed between the pre- and postoperative inter-ilium distance and pelvic canal ratios. However, a statistically significant difference was found in the hemipelvic canal ratio between the pre- and postoperative measurements (p
