【摘要】:目的评价应用闭口万向螺钉(closed multi-axial screws,CMAS)骶髂固定系统联合后路部分脊柱内固定系统行腰椎-骨盆内固定治疗不稳定型骶骨骨折的临床效果。方法回顾分析2013年1月—2014年11月采用CMAS骶髂固定系统联合后路部分脊柱内固定系统行腰椎-骨盆内固定治疗的25例(39侧)不稳定型骶骨骨折患者临床资料。其中男17例,女8例;年龄19~55岁,平均33.9岁。致伤原因:交通事故伤15例,高处坠落伤8例,挤压伤2例。受伤至入院时间1~13 d,平均3.5 d。骨折按Denis分型:Ⅰ型2侧,Ⅱ型20侧,Ⅲ型17侧。术前20例伴神经损伤,根据Gibbons评分Ⅰ级2例,Ⅱ级2例,Ⅲ级7例,Ⅳ级9例。术后2 d根据Matta标准对骨折复位质量进行评价,根据Majeed功能评分标准及Gibbons评分标准分别对临床功能和神经功能进行评价。结果手术时间80~150 min,平均110 min;术中出血量250~1 400 mL,平均570 mL。2例术后出现切口感染,经清创术及抗生素治疗后愈合。25例患者均获随访,随访时间15~22个月,平均18个月。X线片及CT复查示骶骨骨折均达临床愈合,愈合时间8~12周,平均10周。根据Matta评分标准评估骨折复位质量,获优32侧、良好6侧、一般1侧,优良率97.5%。术后12~20个月,平均13个月取出内固定物,无螺钉松动、断裂,内固定物与周围组织无粘连,未见明显电解离现象发生。末次随访时,根据Majeed标准评价临床功能,为64~98分,平均84.7分;获优18例、良好5例、一般2例,优良率92.0%。20例神经损伤者其神经功能较术前明显恢复,Gibbons评分获Ⅰ级8例,Ⅱ级8例,Ⅲ级3例,Ⅳ级1例。结论应用CMAS骶髂固定系统联合后路部分脊柱内固定系统行腰椎-骨盆内固定治疗不稳定型骶骨骨折,不仅为骶骨骨折提供了坚强固定,实现早期完全负重,而且可进行术中骶神经探查及减压以促进神经功能恢复。
[Abstract]:Objective to evaluate the clinical effect of lumbar vertebrae pelvic internal fixation with closed universal screw (closed multi-axial screws,CMAS) sacroiliac fixation system combined with posterior partial spinal internal fixation system in the treatment of unstable sacral fractures. Methods from January 2013 to November 2014, 25 cases (39 sides) of unstable sacral fractures treated with CMAS sacroiliac fixation system combined with posterior partial spinal internal fixation system were retrospectively analyzed. There were 17 males and 8 females, with an average age of 33.9 years (1955 years). The causes of injury were: 15 cases of traffic accident, 8 cases of falling injury and 2 cases of crush injury. The time from injury to admission was 1: 13 days, with an average of 3.5 days. According to Denis classification, type 鈪,
