Scoliosis is a three-dimensional spinal deformity, and paraspinal muscles play an important role as stabilizers of the spinal curve. In this prospective study, we compared elasticity changes in the paraspinal muscles of adolescent patients with scoliosis after surgery or bracing. Elasticity was measured on the concave and convex sides of the paraspinal muscles at the apex of the curve at the beginning of treatment and 6 and 12 months after treatment. Twenty-six patients with correction surgery (n = 15) or bracing (n = 11) were included. At initial evaluation, the Cobb angle was larger in the surgery group (72.3 ± 20.2° in surgery vs. 30.6 ± 5.1° in brace, p < 0.001). The estimated mean elasticity value of the paraspinal muscles was lower in the surgery group at baseline on the convex side (15.8 vs. 22.8 kPa, p = 0.037) and 6 months on both the concave (12.1 vs. 22.7 kPa, p = 0.004) and convex (13.4 vs. 23.8 kPa, p = 0.005) sides. There was a significant stiffness decrease from baseline to 6 months on the concave side in the surgery group (5.9 kPa, p = 0.025). However, the elasticity change recovered at 12 months without significant differences between the two groups.
脊柱侧凸是一种三维的脊柱畸形，脊柱旁肌肉作为脊柱曲度的稳定器起着重要作用。在这项前瞻性研究中，我们比较了脊柱侧凸青少年患者在接受手术或支具治疗后脊柱旁肌肉的弹性变化。在治疗开始时、治疗后 6 个月和 12 个月，在曲线顶点的脊柱旁肌肉的凹侧和凸侧测量弹性。共纳入 26 例接受矫形手术（n = 15）或支具治疗（n = 11）的患者。在初始评估时，手术组的 Cobb 角较大（手术组 72.3 ± 20.2° vs. 支具组 30.6 ± 5.1°，p < 0.001）。基线时，手术组凸侧脊柱旁肌肉的估计平均弹性值较低（15.8 与 22.8 kPa，p = 0.037），6 个月时凹侧（12.1 与 22.7 kPa，p = 0.004）和凸侧（13.4 与 23.8 kPa，p = 0.005）也较低。手术组凹侧从基线到 6 个月的刚度显著降低（5.9 kPa，p = 0.025）。然而，在 12 个月时两组之间没有显著差异，弹性变化得到了恢复。
