A 12-year-old boy with spinal muscular atrophy (SMA) Type II presented 5 years after undergoing spinal growing rod placement with cervical kyphosis at C2-3. He underwent anterior cervical discectomy and fusion but 6 years later developed significant kyphosis at the adjacent C3-4 level.
We describe a rare adjacent segment kyphotic condition in a young man with SMA Type II. Clinicians should be cognizant of the risk of cervical kyphosis in adolescent patients with SMA.
一名 12 岁男孩患有脊髓性肌萎缩症（SMA）Ⅱ型，在接受脊柱生长棒置入术后 5 年出现 C2-3 颈椎后凸。他接受了前路颈椎间盘切除融合术，但 6 年后在相邻的 C3-4 水平出现了明显的后凸。
我们描述了一名 SMA Ⅱ型年轻男性罕见的相邻节段后凸情况。临床医生应意识到 SMA 青少年患者颈椎后凸的风险。
