Objective— To describe a technique for closed reduction and percutaneous insertion of a lag screw for fixation of sacroiliac fracture‐luxations, and to report the success of this technique in stabilizing sacroiliac fracture‐luxations. Study Design— A retrospective clinical study. Study Population— 13 consecutive client‐owned dogs with sacroiliac fracture‐luxations. Methods— Sacroiliac fracture‐luxations were stabilized by using a closed reduction and percutaneous lag screw fixation technique. Preoperative, postoperative, and last re‐examination radiographs were used to assess the location and number of pelvic injuries, other orthopedic injuries, percent reduction of the sacroiliac joint, percent sacral width screw depth, position of the screw, pelvic canal diameter ratio, hemipelvic canal width ratio, and complications. Information on signalment, weight, weight‐bearing status, neurologic status, and complications was obtained from the medical record. Results— Mean percent reduction of the sacroiliac joint was 92.33%. All screws were placed within the sacral body with a mean screw depth/sacral width of 79.03%. No screw loosening occurred. Mean pelvic canal diameter ratios were 0.99, 1.20, and 1.14 preoperatively, immediately postoperatively, and at the last re‐examination, respectively. Nine of 13 dogs were willing to walk on the ipsilateral rear leg the day after surgery. Conclusions— Closed reduction and percutaneous insertion of a lag screw for stabilization of fracture‐luxation of the sacroiliac joint is an acceptable method of repair. Clinical Relevance— Sacroiliac fracture‐luxations can be successfully reduced and stabilized using a minimally invasive technique.
