颌面部多发性骨折不同负载内固定治疗模式的临床研究

Multiple fracture treatment with different loading modes of internal fixation in maxillofacial region:a clinical analysis

目的回顾性比较分析颌面部多发性骨折治疗所采用的不同内固定负载模式的疗效差异。方法收集2002—2008年间采用内固定治疗并具有完整资料的颌面部多发性骨折患者31例,对155处骨折内固定所采取的接骨板负载模式及其治疗结果进行对比研究。结果按照4级评价标准,完全负载和共同负载内固定治疗术后的分级结果构成有差异(P<0.005);术后1年随访,2种内固定方法在临床疗效上无显著性差异(P>0.05)。结论共同负载模式内固定有利于骨折断端受到持续性功能性力学刺激,在颌面骨折治疗中可取得较好的临床效果,能部分取代坚强内固定。

Objetive To compare two kinds of different load modes of internal fixation in the treatment of maxillofacial multiple fracture. Methods The 31 patients from 2002 to 2008 with 155 fractures fixed were investigated and anlayzed, and the comparative study was chosen to find out the difference between two kinds of load modes. Results According to the four-rank evaluation criterion, the re- sults between load bearing fixation and load shearing fixation had constitutive difference （P 〈 0. 005 ）. Two kinds of fixaton didn＇t have significant differece after one-year follow up（P 〉 0. 05 ）. Conclusions The load sharing fixation had the advantage of having the fracture suffer from the durative stimulation of functional force. It could partly substitute the rigid internal fixation in the maxillofiacial fracture and get excellent results.
