Navigation-Assisted Percutaneous Fixation of an Anterior Column and Posterior Hemitransverse Fracture in an Elderly Patient: A Case Report.
Article in Journal of orthopaedic case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Acetabular fractures in elderly patients are often the result of low-energy trauma and are complicated by osteopenia, comorbidities, and limited physiologic reserve. Minimally invasive approaches, such as percutaneous fixation have emerged as viable alternatives to open reduction in selected fracture patterns. Case Report: We report the case of a 76-year-old male with a history of coronary artery disease, hypertension, hyperlipidemia, and osteopenia who sustained a comminuted right anterior column and posterior hemitransverse acetabular fracture following a ground-level fall. His hospital course was complicated by rhabdomyolysis and elevated troponin levels, necessitating cardiac evaluation, which demonstrated normal left ventricular function and no evidence of valvular disease. Given the fracture pattern and his polytrauma status, including an ipsilateral proximal humerus fracture and multiple rib fractures, he underwent navigated percutaneous screw fixation of the right acetabulum using O-arm-assisted guidance and iFuse TORQ TNT screws (SI-Bone, Santa Clara, California). Outcome: The patient recovered well without perioperative or post-operative complications. Radiographs at 6 months post-operatively demonstrated fracture healing and stable hardware. He achieved independent ambulation with full, pain-free, passive right hip range of motion. Conclusion: This case highlights the successful application of image-guided percutaneous fixation in an elderly patient with polytrauma and poor bone quality. The use of 3-dimensional navigation and larger-diameter porous screws may offer a biomechanical advantage with improved fixation in osteoporotic acetabulum fractures. Further studies are warranted to evaluate long-term outcomes in this patient population.
