Thoraco-lumbar traumatic vertebral fractures augmentation by osteo-conductive and osteo-inductive bone substitute containing strontium-hydroxyapatite: our experience.

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
introductionThe aim of our study was to evaluate the effectiveness of osteointegrable strontium-hydroxyapatite (Sr-HA) bone cement in the treatment of thoracolumbar traumatic vertebral fractures by percutaneous vertebroplasty (VTP).
methodsWe treated 35 patients [29 (82.85 %) men, 6 (17.14 %) women, mean age 34.05 ± 8.36 years (range 21-54 years)] with single type A1.1 and A1.2 thoracolumbar traumatic vertebral fracture without endospecal bone fragments. Pain intensity was evaluated before and at 1 day; 1 week; and 1, 6, and 12 months after VTP by a 10-point visual analog scale (VAS) score (0 = no pain, 10 = unbearable pain). Physical status and quality of life were evaluated by Oswestry Disability Index (ODI) questionnaire before and 1, 6, and 12 months after VTP.
resultsProcedural technical success was achieved in all patients with no deaths observed during follow-up. In three patients (8.57 %), postprocedural CT showed cement leakages: one intradiscal and two in venous plexus. No adjacent vertebral body fractures nor intrasomatic recollapse was detected. The VAS and ODI scores showed a statistically significant reduction 1 week after procedure (P value <0.0001) with a progressive statistically significant reduction during follow-up (P value <0.0001). Twenty-three patients (65.71 %) assigned a value of 0 to the VAS scale at 1 year after treatment.
conclusionsStrontium-hydroxyapatite bone cement is an effective and safe bone filler in percutaneous vertebroplasty with low leakage rate and absence of major complications when performed by a skilled equipe. It allows an immediate and long-lasting stabilization with a significant pain reduction and quality of life improvement.
