TiRobot-assisted percutaneous vertebroplasty in the management of middle and upper thoracic osteoporotic vertebral compression fracture.
Article in BMC surgery, 2025. 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
purposeThis study aimed to evaluate the clinical efficacy and safety of TiRobot-assisted PVP surgery in the treatment of middle and upper thoracic OVCF. We also aimed to determine (1) changes in Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) before and after treatment, (2) imaging changes of the fractured vertebra, (3) operation time and intraoperative blood loss, (4) frequency of puncture and fluoroscopy, hospital stay, radiation exposure of patient and surgeon, and (5) bone cement leakage and distribution and operation-related complications.
methodsA retrospective analysis was performed on 62 patients with OVCF of the middle and upper thoracic vertebrae (T1-T8) who underwent PVP surgery in Shenzhen Traditional Chinese Medicine Hospital from January 2017 to January 2023. Of them, 30 and 32 patients underwent TiRobot-assisted PVP surgery (robot group) and conventional C-arm-assisted PVP surgery (conventional group), respectively. VAS and ODI scores and the anterior height and local kyphotic angle of the fractured vertebra were compared before surgery and 3 days, 1 month, and 1 year after surgery. Simultaneously, the operation time, intraoperative blood loss, puncture frequency, fluoroscopy frequency, hospital stay, surgeon radiation exposure, patient radiation exposure, bone cement leakage, cement distribution, and complication were compared between the two groups.
resultsVAS score and ODI score at 3 days, 1 month, and 1 year after surgery were significantly improved in both groups compared with those before surgery (p < 0.05). The VAS score of the robot group was lower than that of the conventional group 3 days after surgery (p < 0.05), with no significant difference observed before and after surgery (p > 0.05). No significant difference was observed in anterior height and local kyphotic angle of fractured vertebra between the two groups before and after the surgery (p > 0.05). The operation time, intraoperative blood loss, puncture frequency, fluoroscopy frequency, hospital stay, surgeon radiation exposure, patient radiation exposure, bone cement leakage, and cement distribution of the robot group were all better than those of the conventional group (p < 0.05). Simultaneously, the incidence of complications in the robot group was 3.33% (1/30) lower than that of the conventional group (15.62%) (5/32) (p < 0.05).
conclusionsCompared with traditional PVP surgery, the use of TiRobot-assisted PVP in the treatment of middle and upper thoracic OVCF has the advantages of accuracy, safety, and low-radiation exposure, which can further improve surgical safety, reduce bone cement leakage, and achieve satisfactory clinical efficacy.
