目的:分析青少年特发性脊柱侧凸(AIS)女性患者瘦素、可溶性瘦素受体(sOB-R)水平与其躯体生长发育特征的关系,探讨瘦素、可溶性瘦素受体浓度在AIS女性患者躯体生长发育特征异常中的可能作用.方法:研究对象包括63例单胸弯AIS女性患者和27例同龄健康女孩.测量所有AIS组和对照组女孩的身高及体重.AIS患者与正常对照青少年的体重指数计算方法为BMI =体重(kg)/臂长2 (m2).运用酶联免疫
目的:探讨凸侧短段肋骨切除术在青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)矫形中的作用.方法:对66例采用后路全椎弓根螺钉矫形的AIS患者进行回顾性分析,根据是否进行凸侧短段肋骨切除术分为两组:A组,凸侧短段肋骨切除术组,行后路全椎弓根螺钉侧凸矫形术及凸侧短段肋骨切除术;B组,对照组,单纯进行后路全椎弓根螺钉侧凸矫形术.所有病人随访1年以上,术前及
目的: 探讨前路内固定矫形联合纳米人工骨椎间融合术治疗Lenke 5型特发性脊柱侧凸的融合效果及临床疗效.方法:前路单棒内固定矫形和纳米人工骨椎间融合术的Lenke 5型特发性脊柱侧凸患者共24例.均为女性,年龄12~25岁.术前主弯Cobb角为40 °~56°(平均46.2°).术中在固定区最近端和最远端的椎间隙放入充填好自体肋骨的钛网椎间融合器,而其余间隙则放入充填好纳米磷酸钙人工骨的钛网椎间
