Study aim was to find out if patients with Lenke type 1 curve exhibit smaller pedicles and specific pedicle width pattern compared with individuals with no scoliosis.
4,828 pedicle width measurements (T1-L5) in 61 consecutive patients with adolescent idiopathic scoliosis of Lenke type 1 curve, 61 control subjects, and 20 patients with Lenke type 5 curve, were retrospectively performed by an experienced neuroradiologist.
Among patients with Lenke type 1 curve, the differences between the width of right and left upper thoracic pedicles were statistically significant; smallest at right T4 (2.6 mm). At scoliotic apex, the pedicles on the concave (left) side were significantly smaller than those on the convex (right) side; smallest at left T7 (3.2 mm). Among patients with Lenke type 1 curve, 97% had pedicle width <4 mm.
Our study showed that patients with Lenke type 1 curve exhibit smaller pedicles and asymmetric pedicle width compared with control subjects.
本研究旨在探讨 Lenke 1 型脊柱侧凸患者与无脊柱侧凸患者相比，其椎弓根是否更小，以及椎弓根的宽度是否存在特定模式。
回顾性分析 61 例连续接受治疗的青少年特发性脊柱侧凸 Lenke 1 型患者（61 名对照受试者和 20 例 Lenke 5 型患者）的 4828 个椎弓根宽度测量值（T1-L5），由一位经验丰富的神经放射科医生进行测量。
在 Lenke 1 型脊柱侧凸患者中，右侧和左侧上胸椎椎弓根的宽度差异具有统计学意义；右侧 T4 椎弓根最窄（2.6mm）。在脊柱侧凸顶点处，凹侧（左侧）的椎弓根明显小于凸侧（右侧）；左侧 T7 椎弓根最窄（3.2mm）。Lenke 1 型脊柱侧凸患者中，97%的患者椎弓根宽度<4mm。
本研究表明，与对照组相比，Lenke 1 型脊柱侧凸患者的椎弓根更小，且椎弓根的宽度存在不对称性。
