Iliosacral Screw Fixation for Treating Sacral Fractures: A Modified Pedicle-Guided Fixation Technique in Prone Position.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSacral fractures are posterior pelvic ring injuries which mechanisms range from high-energy trauma to low-energy falls in osteoporotic patients. In surgical treatment, percutaneous approaches have demonstrated significant shorter operation time and less soft tissue damage. In this study, we present a method of iliosacral (SI) screw insertion in prone position, with modified pedicle-guided technique.
methodsThe present study is a retrospective case series of 22 patients for SI screw fixation from February 2019 to September 2023 under our method. Surgical technique was described in detail with images. Perioperative clinical parameters were analyzed. Activity status, complications, data of 10-point visual analogue scale (VAS) for pain and further functional outcomes using the Majeed Pelvic Score (MPS) were recorded. In addition, computed tomography (CT) was routinely performed at 6 months postsurgery to inspect the quality of screws position.
resultsExcellence rate of screw position was 97% upon CT. Two patients had screws partially contacting the cortical bone but not violating sacral foramen, and no neurological symptoms were noted. All screws were secure from possible iatrogenic nerve injuries. VAS scores improved significantly over time and most patients recorded excellent functional recovery. One untoward complication occurred involving unexpected cement extravasation after sacroplasty. No associated neurologic compromise, or clinical evidence of venous emboli thrombosis was reported.
conclusionOur method aims at reducing operation time and radiation exposure to surgeons as conventional two-dimensional fluoroscopy was enough to identify safe insertion corridors in SI screw placement. Performing SI fixation in prone position is also advantageous when dealing with obese patients and concomitant spinal injuries.
