The restauration of the local kyphosis is crucial for spinal fractures outcomes. Recently, the Tektona™, (Spine Art) system, constituted by a flexible lamella for reduction has emerged as a promising solution for osteoporotic fractures. However, no study has yet focused on its results on traumatic fractures.
A retrospective longitudinal study on prospectively collected data was conducted on 53 patients. 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, early post-operative and at follow-up.
Fractures were mainly located at the upper lumbar spine and were Magerl A3.1 type for 51%.
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 vertebroplasty 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).
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.
