The changes in lumbar lordosis angle (LL) and sacral slope angle (SS) related to upper limb elevation and thoracic kyphosis angle (TK) in baseball players with spondylolysis remain unclear. Herein, we investigated baseball players with spondylolysis and those without low back pain, comparing LL and SS with upper limb elevation within and between groups and TK between groups. Baseball players with spondylolysis were enrolled as subjects, and baseball players without low back pain were enrolled as controls (n = 8 each). X-rays were obtained in the standing position and with maximal elevation position of the upper limb (elevation position). LL and SS were measured in the standing and elevated positions, and TK was measured in the standing position. LL was significantly larger in individuals with spondylolysis than controls. The SS of the control group was significantly larger in the elevated position than in the standing position, while the SS of the spondylolysis group was not significantly different between positions. SS was significantly larger in the spondylolysis group than in the control group, only in the standing position. Physical therapy for spondylolysis should focus on hyperlordosis alignment in the standing and maximal elevation positions of both upper limbs, sacral hyper-slope alignment in the standing position, and decreased sacral slope motion.
腰椎前凸角（LL）和骶骨倾斜角（SS）与上肢抬高的变化以及棒球运动员脊柱裂的胸腰椎后凸角（TK）之间的关系尚不清楚。在此，我们调查了患有脊柱裂的棒球运动员和没有腰痛的运动员，比较了组内和组间上肢抬高时的 LL 和 SS 以及组间的 TK。将患有脊柱裂的棒球运动员作为研究对象，将没有腰痛的棒球运动员作为对照组（每组 8 人）。在站立位和上肢最大抬高位（抬高位）时拍摄 X 光片。在站立位和抬高位测量 LL 和 SS，在站立位测量 TK。脊柱裂患者的 LL 明显大于对照组。对照组在抬高位的 SS 明显大于站立位，而脊柱裂组在两个位置之间的 SS 没有明显差异。脊柱裂组的 SS 明显大于对照组，仅在站立位。脊柱裂的物理治疗应侧重于站立位和双侧上肢最大抬高位的过度前凸排列、站立位的骶骨过度倾斜排列以及骶骨倾斜运动的减少。
