为了评估退行性平背（DFB）患者的静态和动态参数特征，并比较成功和不成功手术结果组之间的改善程度，纳入了 47 名 DFB 患者，他们在矫正手术前和术后 6 个月进行了全脊柱 X 射线和三维运动分析。选择 44 名受试者作为对照组。作为静态参数，测量胸椎后凸（TK）、胸腰椎交界处（TLJ）、腰椎前凸（LL）、骨盆倾角（PI）、骶骨倾斜（SS）和骨盆倾斜（PT）。作为动态参数，获得矢状面中骨盆倾斜、下肢关节、胸椎和腰椎的最大和最小角度（动态TK和LL）。 DFB组的TK值较小，LL值较大，骨盆后倾、髋关节屈曲、膝关节屈曲和踝关节背屈均大于对照组。大多数这些参数都通过融合手术得到了显着纠正。动态脊柱参数与静态脊柱参数相关。成功组的最大和最小动态LL比不成功组有显着改善。 DFB 组在动态和静态参数中表现出特征性的下肢和脊柱角度。在脊柱节段中发现了静态和动态参数之间的相关性。动态 LL 是成功手术结果的良好预测因子。
To evaluate characteristics of static and dynamic parameters in patients with degenerative flat back (DFB) and to compare degree of their improvement between successful and unsuccessful surgical outcome groups Forty-seven patients with DFB were included who took whole spine X-ray and three-dimensional motion analysis before and 6 months after corrective surgery. Forty-four subjects were selected as a control group. As static parameters, thoracic kyphosis (TK), thoracolumbar junction (TLJ), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), and pelvic tilt (PT) were measured. As dynamic parameters, maximal and minimal angle of pelvic tilt, lower limb joints, and thoracic and lumbar vertebrae column (dynamic TK and LL) in sagittal plane were obtained. The DFB group showed smaller TK and larger LL, pelvic posterior tilt, hip flexion, knee flexion, and ankle dorsiflexion than the control group. Most of these parameters were significantly corrected by fusion surgery. Dynamic spinal parameters correlated with static spinal parameters. The successful group obtained significant improvement in maximal and minimal dynamic LL than the unsuccessful group. The DFB group showed characteristic lower limb and spinal angles in dynamic and static parameters. Correlation between static and dynamic parameters was found in spinal segment. Dynamic LL was good predictor of successful surgical outcomes.
