PURPOSE
Spinal deformities due to adolescent idiopathic scoliosis (AIS) result in impairment in the back surface topography. Sophisticated interventions are needed that address different aspects of deformity. The purpose of our study is to test the reliability of hand-held 3D scanners on the assessment of AIS.
METHODS
Forty-two AIS patients were included in our study. The back surfaces of the patients were scanned with the hand-held 3D scanner, while the patients were in the standing position with the arms hanging at the sides (P1), with the arms extended (P2), and forward bending position (P3). The acquired original image was superimposed with the mirror image. Root mean square (RMS) of the point-to-point distance was calculated, and the differences between the surfaces were determined. Correlation between RMS, Cobb, POTSI, scoliometer, radiographic rotations, TRACE results was calculated.
RESULTS
A significant correlation coefficency (r) was found between the RMS and Cobb values in the thoracic (P1 = 0.80, P2 = 0.76, P3 = 0.71) and lumbal region (P1 = 0.56, P2 = 0.65, P3 = 0.63); between RMS and Raimondi in the thoracic (r, P1 = 0.80, P2 = 0.81, P3 = 0.78) and lumbar regions (P1 = 0.54, P2 = 0.64, P3 = 0.59); between RMS and scoliometer measurements in the thoracic (r, P1 = 0.58, P2 = 0.50, P3 = 0.41) and lumbar regions (P1 = 0.35, P2 = 0.41, P3 = 0.59); in thoracolumbar region between RMS and POTSI (P1 = 0.50, P2 = 0.25, P3= 0.36), between RMS and TRACE (P1 = 0.68, P2 = 0.5, P3 = 0.52), CONCLUSION: The hand-held scanners may contribute to gaining new insight into diagnosis and follow-up of AIS by its mobility that enables the acquisition of data in desired body position and place such as bedside or our patient clinics.
LEVEL OF EVIDENCE IV
Diagnostic: individual cross-sectional studies with consistently applied reference standard and blinding.
目的
青少年特发性脊柱侧凸（AIS）引起的脊柱畸形导致背部表面形貌受损。需要进行复杂的干预，以解决畸形的不同方面。我们研究的目的是测试手持式 3D 扫描仪在 AIS 评估中的可靠性。
方法
本研究纳入 42 例 AIS 患者。使用手持式 3D 扫描仪对患者的背部进行扫描，患者在站立位，手臂垂在身体两侧（P1）、伸展手臂（P2）和前屈位（P3）。获取原始图像后与镜像图像叠加。计算点到点距离的均方根（RMS），并确定表面之间的差异。计算 RMS 与 Cobb、POTSI、脊柱侧凸计、放射学旋转、TRACE 结果之间的相关性。
结果
在胸椎（P1=0.80，P2=0.76，P3=0.71）和腰椎（P1=0.56，P2=0.65，P3=0.63）区域，RMS 值与 Cobb 值之间存在显著的相关系数（r）；在胸椎（r，P1=0.80，P2=0.81，P3=0.78）和腰椎（r，P1=0.54，P2=0.64，P3=0.59）区域，RMS 值与 Raimondi 值之间存在显著相关系数；在胸椎（r，P1=0.58，P2=0.50，P3=0.41）和腰椎（r，P1=0.35，P2=0.41，P3=0.59）区域，RMS 值与脊柱侧凸计测量值之间存在显著相关系数；在胸腰椎区域（P1=0.50，P2=0.25，P3=0.36），RMS 值与 POTSI 值之间存在显著相关系数，在胸椎（P1=0.68，P2=0.5，P3=0.52）和腰椎（P1=0.68，P2=0.5，P3=0.52）区域，RMS 值与 TRACE 值之间存在显著相关系数。
结论
手持式扫描仪可通过其移动性为 AIS 的诊断和随访提供新的见解，使其能够在所需的体位和位置（如床边或我们的患者诊所）获取数据。
证据水平 IV：诊断：个体横断面研究，应用一致的参考标准和盲法。
