Abstract

Study design: A prospective study.

Objective: To measure 3-dimensional cervical range of motion (ROM) by noninvasive optical tracking-based motion-capture technology in patients undergoing laminoplasty, and to elucidate the postoperative effects of laminoplasty on cervical mobility.

Summary of background data: Cervical laminoplasty is a motion-sparing decompression surgery for degenerative cervical myelopathy. Unlike cervical laminectomy and fusion, the true postoperative impact of laminoplasty on neck motion has not been well studied.

Methods: Participants comprised 25 patients undergoing double-door cervical laminoplasty for degenerative cervical myelopathy in a single center. Maximum flexion/extension, left/right rotation, and left/right side bending were recorded using the motion-capture device preoperatively and 3 months postoperatively. ROMs in 3 orthogonal axes were calculated. Preoperative differences in C2-7 Cobb angles on lateral flexion/extension x-rays were also measured as the radiologic ROM to assess reliability. Preoperative and 1-year postoperative Japanese Orthopaedic Association score, Neck Disability Index [NDI], and Euro-QOL were recorded, and correlations with ROMs were assessed.

Results: Preoperative mean (±SD) ROMs for flexion/extension, rotation, and side bending were 90±17, 107±16, and 53±17 degrees, respectively. Although radiologic sagittal ROM measurement showed a smaller range than motion capture, averaging 36±13 degrees, a moderate to strong correlation between radiologic and motion capture values was observed (R=0.57, P =0.003). Preoperative NDI showed a negative correlation with coronal ROM (rho=-0.547, P =0.02). Postoperative ROM showed a significant reduction in rotation (95±16 degrees, P =0.002) but not in flexion/extension or side bending.

Conclusions: Three-dimensional motion-capture analysis allowed reliable measurement of cervical ROM. Rotational ROM was significantly reduced after laminoplasty, showing that cervical kinematics are still significantly altered.

基于运动捕捉技术的颈椎板层成形术患者活动范围三维测量。

研究设计前瞻性研究：通过无创光学追踪运动捕捉技术测量接受颈椎板成形术患者的三维颈椎运动范围（ROM），并阐明颈椎板成形术对颈椎活动度的术后影响：颈椎椎板成形术是一种治疗退行性颈椎病的减压手术。与颈椎椎板切除术和融合术不同，颈椎板成形术术后对颈部活动的真正影响尚未得到充分研究：研究对象包括在一个中心接受双门颈椎板成形术治疗退行性颈椎病的 25 名患者。术前和术后3个月使用运动捕捉装置记录最大屈/伸、左/右旋转和左/右侧屈。计算了3个正交轴的ROM。此外，还测量了侧屈/伸展X光片上C2-7 Cobb角的术前差异，以评估放射学ROM的可靠性。记录术前和术后一年的日本骨科协会评分、颈部残疾指数[NDI]和欧洲生活质量指数（Euro-QOL），并评估与ROM的相关性：术前屈伸、旋转和侧弯的平均（±SD）ROM分别为90±17度、107±16度和53±17度。虽然放射学矢状面ROM测量显示的范围小于运动捕捉，平均为36±13度，但放射学值和运动捕捉值之间存在中度到高度的相关性（R=0.57，P=0.003）。术前 NDI 与冠状位 ROM 呈负相关（rho=-0.547，P=0.02）。术后ROM显示旋转显著减少（95±16度，P=0.002），但屈伸或侧屈没有减少：结论：三维运动捕捉分析可以可靠地测量颈椎的ROM。结论：三维运动捕捉分析能够可靠地测量颈椎的ROM，而椎板成形术后旋转ROM明显减少，这表明颈椎运动学仍有明显改变。

期刊介绍： Clinical Spine Surgery is the ideal journal for the busy practicing spine surgeon or trainee, as it is the only journal necessary to keep up to date with new clinical research and surgical techniques. Readers get to watch leaders in the field debate controversial topics in a new controversies section, and gain access to evidence-based reviews of important pathologies in the systematic reviews section. The journal features a surgical technique complete with a video, and a tips and tricks section that allows surgeons to review the important steps prior to a complex procedure. Clinical Spine Surgery provides readers with primary research studies, specifically level 1, 2 and 3 studies, ensuring that articles that may actually change a surgeon’s practice will be read and published. Each issue includes a brief article that will help a surgeon better understand the business of healthcare, as well as an article that will help a surgeon understand how to interpret increasingly complex research methodology. Clinical Spine Surgery is your single source for up-to-date, evidence-based recommendations for spine care.
