摘要:

目的:探讨重建钢板置入内固定抗剪力及稳定性和可塑性,并认识其在治疗髋臼骨折合并关节内前方游离骨块中的作用。
方法:应用计算机应用计算机检索Science Direct 数据库、Ei数据库1960-01/2009-10期间的相关文章,检索词为“cetabular fractures,modified ilioinguinal approach,reconstruction plate”,并限定文章语言种类为English。同时计算机检索中国期刊全文数据库、中国生物医学文献数据库等1994-01/2009-10期间的相关文章,检索词为“髋臼骨折,内固定,重建钢板”,并限定文章语言种类为中文。此外还手工查阅相关专著数部。纳入有关重建钢板内固定治疗髋臼骨折治疗方式研究,包括基础与临床实验。
结果:髋臼顶部是人体负重区,术中力求骨折解剖复位。在重建钢板进行髋臼骨折内固定之前,可在直视下用骨钩、克氏针等作暂时骨折内固定,调整骨盆钢板弯度折弯塑形并与髋臼顶后壁外侧或与前壁内侧一致再拧入螺钉进行骨折内固定,术中还应当注意进钉角度避免入髋臼内。术中认为一块钢板内固定不是很满意时,可加用一至二枚皮质骨螺钉或克氏针作加强内固定,但克氏针针尾一定要折弯,防止克氏针松脱移位误入盆腔;也可加用一块重建钢板进行内固定等。重建钢板内固定在髋臼骨折治疗中的优点有可抵抗剪力,稳定性高,重建钢板可塑性强,可充分预弯来适应髋臼部位的特殊形态,术后钢板松动、断裂发生率低,复位满意,固定牢靠。游离骨块可用克氏针临时固定在获得满意固定后再用重建钢板进行固定。
结论:重建钢板内固定治疗髋臼横行骨折合并关节前方游离骨块,临床效果好,并发症少

Abstract:

OBJECTIVE: To explore the anti-shear force, stability and plasticity of reconstruction plate implantation, and to investigate its role in treating acetabular fractures complicated by free bone graft in the joint.
METHODS: A computer-based online search of Science Direct and Ei databases (1960-01/2009-10) was performed for related English articles with the keywords of “acetabular fractures, modified ilioinguinal approach, reconstruction plate”. In addition, CNKI and CBM database (1994-01/2009-10) were searched for related Chinese articles with the same key words in Chinese. Moreover, related works were manually searched. Studies regarding reconstruction plate implantation in treating acetabular fractures were included, including basic and clinical experiments.
RESULTS: Acetabular top is weight loading region of human body, and the fracture should be reducted by the operation. Prior to reconstruction plate for acetabular fracture fixation, bone hook, and Kirschner wire can be used for temporary fixation, and the plate bending angle should be adjusted to accordant with lateral posterior wall or medial anterior wall of the acetabular top, followed by screw threading for fracture fixation. In addition, the screw entrance angle is very important. If the fixation of one plate is not satisfactory, one or two cancellous bone screw or Kirschner wire can be used to enhance the fixation. But the Kirschner wire tail should be bended to prevent dislocation into the pelvic cavity. Moreover, additional plate can be used for further fixation. Reconstruction plate fixation has advantages of anti-shear force, high stability and plasticity, which fully adapt the special appearance of acetabulum. Moreover, the incidence of postoperative plate loosening and breakage is low, and the satisfaction is high. Free bone blocks can be temporarily fixed by Kirschner wire, followed by reconstruction plate fixation.
CONCLUSION: Reconstruction plate fixation has good clinical effect and few complications in treating acetabular fractures complicated by free bone blocks in the joint.
