Background The restauration of the local kyphosis is crucial to thoracolumbar fractures outcomes. Recently, the Tektona™ (Spine Art) system, constituted by a flexible lamella for corporeal reduction has emerged as a promising solution for osteoporotic fractures. However, no study has yet focused on its results on traumatic fractures. Methods A retrospective longitudinal study on prospectively collected data was conducted on 53 patients that had a kyphoplasty by Tektona™, associated or not to percutaneous fixation. The data collected were clinical, surgical and scannographic (measurement of AVH, MVH and PVH (anterior/medium/posterior vertebral height), and RTA (regional traumatic angle) in°), preoperatively, post-operatively and at last follow-up. Results Fractures were mainly located at the upper lumbar spine and were AOSpine A3 type for 74%. The mean RTA was 12° in pre-operative, 4° in post-operative ( p = 2e   − 9  ), and 8° at the last follow-up ( p = 0,01 ). The mean correction of RTA for the fixation group was − 10 ± 6° versus − 7 ± 4° for the kyphobroplasty alone group  (p = 0,006).  The mean correction for fractures located at T10-T12 was − 9 ± 3°, − 9 ± 5° for L1, − 8 ± 3° for L2 and − 5 ± 3° for L3-L5  (p = 0,045).  Conclusions The Tektona® system appears to be efficient for acute thoraco-lumbar fractures, comparable to other available systems, allowing a real intracorporeal reduction work. Its relevance, especially in the long term needs further investigation. The association of a percutaneous fixation allow to obtain a better correction of the RTA but did not seem to prevent the loss of correction at follow-up.
