Clinical efficacy comparison of Mazor X robot-assisted and traditional freehand techniques in the treatment of atlantoaxial fracture and dislocation.

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
backgroundThe optimal treatment strategy for atlantoaxial fracture-dislocation remains a focal point of clinical research and a subject of ongoing debate, with a paucity of definitive comparative clinical studies.
objectiveWith the increasing application of robot-assisted (RA) technology in spinal surgery, the present study aims to compare the clinical efficacy of traditional fluoroscopy-assisted freehand screw placement (FA) and robot-assisted screw placement in the treatment of atlantoaxial fracture-dislocation, providing a reference for clinical practice.
methodsThis retrospective study analyzed the clinical data of 59 patients with atlantoaxial fracture-dislocation who underwent surgical treatment at Honghui Hospital in Xi'an from May 2023 to August 2024. Patients were divided into two groups based on the method of screw placement: the freehand group (n = 36) and the robot-assisted group (n = 23). Data on surgical time, intraoperative blood loss, postoperative hospital stay, and the incidence of complications, such as vascular, neural, and spinal cord injuries were collected. The accuracy of pedicle screw placement was evaluated using the Gertzbein and Robbins scoring system. Treatment outcomes were assessed using visual analog scale (VAS) scores for pain, Japanese Orthopaedic Association (JOA) scores for cervical spine function, and the incidence of postoperative complications.
resultsAll 59 patients successfully underwent surgery, with significant postoperative improvement in symptoms. The study results demonstrated that the robotic-assisted group had significantly longer operative times (171.1 ± 23.6 min) and higher intraoperative blood loss (305.9 ± 53.7 ml) compared with the manual group (operative time: 109.9 ± 18.5 min; intraoperative blood loss: 185.0 ± 21.2 ml), with statistically significant differences between the two groups (P < 0.01). However, the robotic-assisted group exhibited significantly higher accuracy and safety in screw placement (96.5%) compared with the manual group (87.4%), and the postoperative hospital stay was significantly shorter in the robotic-assisted group (4.3 ± 1.0 days) than in the manual group (6.3 ± 1.2 days), with statistically significant differences between the two groups (P < 0.01). Moreover, at the final follow-up, the Visual Analog Scale (VAS) scores and Cervical Japanese Orthopaedic Association (JOA) scores of all patients had significantly improved compared with preoperative values (P < 0.05).
conclusionIn the treatment of atlantoaxial fracture-dislocation, robot-assisted techniques offer significant advantages in terms of screw placement accuracy and safety compared with traditional freehand methods, and effectively reduce postoperative hospital stay duration. These findings suggest that robot-assisted technology holds great promise for complex spinal surgeries and is worthy of further promotion and application in clinical practice.
