RESUMEN
PURPOSE: Idiopathic scoliosis is an evolutive deformity during patient's life. In case of moderate deformity in a well aligned adolescent, it's a big concern to decide when to do the surgery. Objective of this work was to evaluate and compare clinical, radiological and surgical data of patients with adolescent idiopathic scoliosis operated in childhood (before 20 years) and those operated adults (after 35 years). METHODS: In this retrospective multicenter study, inclusion period extended from 2008 to 2018. Two groups were defined, those operated on before the age of 20 (YAIS), and those operated on after 35 years (OAIS). Demographic, radiographic and surgical data were collected. At follow-up, radiographic data and functional outcomes (VAS, SRS, SF12, Oswestry) were analyzed. Minimum FU was 5 years for young and 2 years for old patients. RESULTS: YAIS group included 364 patients, and OAIS group, 131 patients. In both groups, deformity was important (mean Cobb 63°). Vertebral osteotomies were significantly more frequent, fusions and length of stays were longer for old than young patients. Main Cobb correction was better in young than old (37 ± 10° vs 2 ± 13°, p = 0.03). Functional outcomes were better for young, operated patients than for operated groups after 35 years (SF12 PCS 50 ± 7 vs 39 ± 6, p = 0.02). The same trends were observed at longer follow-up. CONCLUSION: Surgery for idiopathic scoliosis seems to offer a better quality of life and deformity correction when it is performed at adolescence. After 35 years, surgery remains an acceptable therapeutic option, despite higher complication rate.

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.
