改良Halo-骨盆架分期牵引治疗重度僵硬性脊柱侧凸的疗效分析

目的：探讨改良Halo-骨盆架分期牵引联合手术治疗重度僵硬性脊柱侧凸的临床疗效。方法：自2004年1月至2010年5月治疗50例重度僵硬性脊柱侧凸患者,男23例,女27例;年龄4～16岁,平均10.8岁;先天性脊柱侧凸24例（分节不良11例,形成障碍7例,混合型6例）,特发性脊柱侧凸26例。采用改良Halo-骨盆架分期牵引联合手术治疗：Ⅰ期术前牵引,Ⅱ期松解牵引,Ⅲ期牵引矫形内固定。对治疗前后患者身高、侧凸Cobb角、后凸Cobb角及矫正率进行观察。结果：患者身高由治疗前平均（152.1±11.1）cm矫正至（158.5±10.5）cm,侧凸Cobb角由平均（91.8±14.5）°矫正至（30.8±7.9）°,后凸Cobb角由平均（69.5±14.0）°矫正至（31.6±10.1）°。Ⅰ期术前牵引后侧凸、后凸Cobb角平均矫正率分别为（30.4±6.6）%、（22.3±5.2）%;Ⅱ期松解牵引后侧凸、后凸Cobb角平均矫正率分别为（26.7±5.1）%、（21.2±6.0）%;Ⅲ期牵引矫形内固定后侧凸、后凸Cobb角平均矫正率分别为（33.7±7.2）%、（27.1±5.3）%（矫正率参照的基准Cobb角是上一期治疗的Cobb角）;分期牵引联合手术治疗的侧凸、后凸Cobb角平均矫正率分别为（66.5±7.2）%、（55.1±6.4）%。各期治疗前后患者身高、侧凸Cobb角、后凸Cobb角及矫正率差异均有统计学意义（P〈0.05）。结论：采用改良Halo-骨盆架分期牵引联合手术治疗重度僵硬性脊柱侧凸,可获得良好的畸形矫正和躯干平衡,并能减少术中、术后并发症,具有临床可操作性。

Analysis of the clinical effects of the modified Halo pelvic frame for the treatment of severe scoliosis with rigidity

Objective:To evaluate the clinical curative effect of the modified Halo pelvic frame and surgery for the treatment of severe scoliosis with rigidity. Methods:From January 2004 to May 2010,50 patients with severe scoliosis patients with rigidity were treated in our hospital. Twenty-three patients were male and 27 patients were female,with a mean age of 10.8 years old,ranging from 4 to 16 years. Twenty-four patients were congenital scoliosis and 26 patiens were idiopathic scoliosis. The mean body height were(...
