Multi-center, prospective, observational cohort.
To compare myelopathic vs. non-myelopathic ambulatory patients in short- and long-term neurologic function, operative treatment, and patient-reported outcomes.
Pediatric deformity patients from 16 centers were enrolled with the following inclusion criteria: aged 10-21 years-old, a Cobb angle ≥100° in either the coronal or sagittal plane or any sized deformity with a planned 3-column osteotomy, and community ambulators. Patients were dichotomized into 2 groups: myelopathic (abnormal preoperative neurologic exam with signs/symptoms of myelopathy) and non-myelopathic (no clinical signs/symptoms of myelopathy).
Of 311 patients with an average age of 14.7 ± 2.8 years, 29 (9.3%) were myelopathic and 282 (90.7%) were non-myelopathic. There was no difference in age ( = 0.18), gender ( = 0.09), and Risser Stage ( = 0.06), while more patients in the non-myelopathic group had previous surgery (16.1% vs. 3.9%; = 0.03). Mean lower extremity motor score (LEMS) in myelopathic patients increased significantly compared to baseline at every postoperative visit: Baseline: 40.7 ± 9.9; Immediate postop: 46.0 ± 7.1, = 0.02; 1-year: 48.2 ± 3.7, < 0.001; 2-year: 48.2 ± 7.7, < 0.001). The non-myelopathic group had significantly higher LEMS immediately postoperative ( = 0.0007), but by 1-year postoperative, there was no difference in LEMS between groups (non-myelopathic: 49.3 ± 3.6, myelopathic: 48.2 ± 3.7, = 0.10) and was maintained at 2-years postoperative (non-myelopathic: 49.2 ± 3.3, myelopathic: 48.2 ± 5.7, = 0.09). Both groups improved significantly in all SRS domains compared to preoperative, with no difference in scores in the domains for pain ( = 0.12), self-image ( = 0.08), and satisfaction ( = 0.83) at latest follow-up.
In severe spinal deformity pediatric patients presenting with preoperative myelopathy undergoing spinal reconstructive surgery, myelopathic patients can expect significant improvement in neurologic function postoperatively. At 1-year and 2-year postoperative, neurologic function was no different between groups. While non-myelopathic patients had significantly higher postoperative outcomes in SRS mental-health, function, and total-score, both groups had significantly improved outcomes in every SRS domain compared to preoperative.
多中心、前瞻性、观察性队列研究。
比较脊髓病性与非脊髓病性门诊患者的短期和长期神经功能、手术治疗及患者报告的结局。
来自16个中心的小儿脊柱畸形患者符合以下纳入标准：年龄10 - 21岁，冠状面或矢状面Cobb角≥100°，或任何大小的畸形且计划行三柱截骨术，以及社区行走者。患者被分为两组：脊髓病性（术前神经检查异常且有脊髓病体征/症状）和非脊髓病性（无脊髓病临床体征/症状）。
311例患者平均年龄为14.7±2.8岁，其中29例（9.3%）为脊髓病性，282例（90.7%）为非脊髓病性。两组在年龄（P = 0.18）、性别（P = 0.09）和Risser分期（P = 0.06）方面无差异，而非脊髓病性组既往有手术史的患者更多（16.1%对3.9%；P = 0.03）。脊髓病性患者术后每次随访时的平均下肢运动评分（LEMS）与基线相比均显著增加：基线时：40.7±9.9；术后即刻：46.0±7.1，P = 0.02；1年时：48.2±3.7，P < 0.001；2年时：48.2±7.7，P < 0.001）。非脊髓病性组术后即刻的LEMS显著更高（P = 0.0007），但术后1年时，两组间的LEMS无差异（非脊髓病性组：49.3±3.6，脊髓病性组：48.2±3.7，P = 0.10），且在术后2年时保持无差异（非脊髓病性组：49.2±3.3，脊髓病性组：48.2±5.7，P = 0.09）。与术前相比，两组在所有SRS领域均有显著改善，在最新随访时疼痛（P = 0.12）、自我形象（P = 0.08）和满意度（P = 0.83）领域的评分无差异。
在患有术前脊髓病的严重脊柱畸形小儿患者接受脊柱重建手术时，脊髓病性患者术后神经功能有望显著改善。术后1年和2年时，两组间神经功能无差异。虽然非脊髓病性患者在SRS心理健康、功能和总分方面的术后结局显著更高，但与术前相比，两组在每个SRS领域的结局均有显著改善。
