文题释义:
三维重建CT:通过运用表面遮盖法、最大密度投影法、多平面重建法等技术手段,对二维CT的影像数据进行分析处理,最终生成高质量的三维图像。由此产生的CT三维图像直观、立体、空间立体感强,能够清晰显示各自的解剖关系和毗邻关系,能为临床工作提供更多更全面更准确的有价值的信息,能弥补普通X射线平片和常规CT扫描的不足。
一干三枝分型:基于三维重建CT的骨盆髋臼一干三枝分型法。将完整的骨盆髋臼分为一干和三枝。干:耻骨联合、界线、骶骨;三枝:髂枝、方形枝、后壁枝。具体在临床中可见这4种骨折类型:①单干或者单枝骨折(单干,单髂枝,单方形枝,单后壁枝);②一干一枝骨折(一干合并髂枝骨折,一干合并方形枝骨折,一干合并后壁枝骨折);③一干二枝骨折(一干合并髂枝和方形枝骨折,一干合并髂枝和后壁枝骨折,一干合并方形枝和后壁枝骨折);④一干三枝骨折(一干合并髂枝、方形枝和后壁枝骨折)。
 
摘要
背景:目前尚未有一种系统的分型法能完全、精确、直观地反映骨盆髋臼骨折的特点。螺旋三维重建CT技术为诊断骨盆髋臼骨折提供了直观、全面的影像学资料。
目的:介绍基于三维重建CT的骨盆髋臼骨折一干三枝分型法,并评价其在指导临床修复手术中的作用。
方法:纳入47例骨盆髋臼骨折患者,根据一干三枝分型法,18例单干或者单枝骨折,18例一干一枝骨折,7例一干二枝骨折,4例一干三枝骨折。根据一干三枝分型法选择修复方案:手术入路可分为改良的Stoppa入路、髂腰三角固定后入路、髂窝入路和K-L入路,术中选用一种或者多种联合;入路及固定顺序:先干后枝,若相连的枝已同时复位,无需另选入路及固定,如果没有复位,可能存在旋转,需另选入路及固定。术后随访评价临床效果。
结果与结论:①单干或者单枝骨折、一干一枝骨折、一干二枝骨折、一干三枝骨折的平均手术时间分别为75.2,88.5,97.4,115.8 min,平均失血量分别为321.2,360.4,450.5,650.0 mL;②骨盆骨折术后复位优良率按Matta标准评定:优18例,良27例,可1例,差1例,优良率为96%;髋臼骨折术后复位满意率按Matta标准评定:解剖复位25例,满意复位20例,不满意复位2例,满意率为96%;③所有骨折随访12-35个月,随访率为87%,所有骨盆髋臼骨折平均愈合时间为2.9个月(2.7-4.2个月),平均完全负重时间为3.8个月(2.5-5.6个月);④末次随访时骨盆骨折术后疗效评定按照Majeed量化评分评定:优16例,良25例,可4例,差2例,优良率为87%;末次随访时髋关节功能疗效评定按照改良d'Aubigne和Postel评分标准评定:优15例,良24例,可6例,差2例,优良率为83%。无术后并发症发生;⑤结果表明,基于三维重建CT的骨盆髋臼一干三枝分型在指导骨盆髋臼骨折治疗方法的选择上具有重要意义,有助于指导选择选择手术入路和入路及固定顺序,从而提高骨盆髋臼骨折的治疗效果。

Abstract:

BACKGROUND: There is no systematic classification method that can completely, accurately and directly reflect the characteristics of pelvic and acetabular fractures. Three-dimensional (3D) CT reconstruction technique provides more imaging evidences for the diagnosis of pelvic and acetabular fractures.

OBJECTIVE: To introduce the “one trunk-three branches” classification for pelvic and acetabular fractures based on 3D CT reconstruction, and to evaluate its clinical effect.
METHODS: Forty-seven cases of pelvic and acetabular fractures were enrolled, involving 18 cases of “single trunk or single branch” fracture, 18 cases of “one trunk-one branch”, 7 cases of “one trunk-two branches”, and 4 cases of “one trunk-three branches”. Based on the “one trunk-three branches” classification, the surgical approaches included improved Stoppa, posterior iliac-lumbar, iliac fossa and K-L approaches, and one or combined approaches were recommended. The order of approach and fixation was as follows: trunk first followed by branch, and another approach was necessary when the conjoint branches did not achieve simultaneous reduction. The clinical efficacy was evaluated through postoperative follow up.
RESULTS AND CONCLUSION: (1) The average operation time of the fractures of single trunk or one branch, one trunk-one, one trunk-two branches and one trunk-three branches was 75.2, 88.5, 97.4, and 115.8 minutes, respectively; the average blood loss was 321.2, 360.4, 450.5, and 650 mL, respectively. (2) According to the criteria described by Matta, 25 of the reductions were graded excellent, 20 were graded good, and 2 were poor, and the excellent and good rate was 96%. (3) All patients were followed up for 12-35 months, and the follow-up rate was 87%. The mean healing time was 2.9 months (2.7-4.2 months), and the mean weight bearing time was 3.8 months (2.5-5.6 months). (4) At the last follow up, the clinical outcomes (Majeed criteria) were 16 excellent, 25 good, 4 average and 2 poor, and the excellent and good rate was 87%; the clinical outcomes (Merle d’Aubigne-Postel) were 15 excellent, 24 good, 6 average, and 2 poor, and the excellent and good rate was 83%. None of complications occurred. (5) These results manifest that the “one trunk-three branches” classification for pelvic and acetabular fractures based on 3D CT reconstruction is helpful for designing an appropriate treatment scheme, and choosing optimal surgical approach and fixation order, thereby promoting the functional recovery of the pelvis and acetabulum.
