这项研究的目的是确定密尔沃基支具和胸腰骶骨矫形器(TLSO)对青少年Scheuermann\'s后凸(SK)的头骨盆矢状位的影响。共研究了52名接受支撑治疗的SK青少年。他们接受了头部到骨盆的双平面射线照相(EOS成像,巴黎,法国)在开始支撑之前和之后6个月。我们测量了T1斜率,颈部倾斜(NT),颈椎矢状面垂直轴(cSVA),胸廓入口角(TIA),C0-C2脊柱前凸,C2-C7脊柱前凸,胸椎后凸(TK),腰椎前凸(LL),骨盆发病率(PI),骨盆倾斜(PT),骶骨斜坡(SS),矢状垂直轴(SVA)和T1脊柱骨盆倾角(T1SPi)。TIA基线值无显著差异,PT,SS,PI,SVA,TK,cSVA,两组间NT和T1斜率比较(p>0.05)。T1斜率的基线和最终测量值之间存在显着差异,cSVA,TK,LL,T1SPi和TIA在两组中均有统计学意义(p<0.05)。结果表明,支具治疗可以显着影响SK青少年的头部到骨盆矢状参数。然而,比较TLSO和密尔沃基支架的短期效果时,头骨盆矢状参数值没有显着差异。
The aim of this study was to determine the effects of the Milwaukee brace and thoracolumbosacral orthosis (TLSO) on head to pelvis sagittal alignment in adolescents with Scheuermann\'s kyphosis (SK). A total of 52 adolescents with SK who were under brace treatment were studied. They underwent biplanar radiography of the head to pelvis (EOS Imaging, Paris, France) before and 6 months after the beginning of bracing. We measured T1 slope, neck tilt (NT), cervical sagittal vertical axis (cSVA), thoracic inlet angle (TIA), C0-C2 lordosis, C2-C7 lordosis, thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), sagittal vertical axis (SVA) and T1 spinopelvic inclination (T1SPi). There were no significant differences in baseline values of TIA, PT, SS, PI, SVA, TK, cSVA, NT and T1 slope between the two groups (p > 0.05). There were significant differences between the baseline and final measurements of T1 slope, cSVA, TK, LL, T1SPi and TIA in both groups (p < 0.05). The results imply that brace treatment can significantly affect head to pelvis sagittal parameters of adolescents with SK. However, there are no significant differences in the values of head to pelvis sagittal parameters when comparing short-term effect of TLSO and the Milwaukee brace.
