两种内固定技术治疗下颌骨骨折的对比研究

目的:观察下颌骨骨折治疗中加压内固定和非加压内固定的疗效差异,对两种固定形式的临床应用作出评价。方法:下颌骨骨折57例分成两组,分别采用加压内固定和非加压内固定进行治疗,对比研究两组病例术后愈合情况,功能恢复,X片检查结果等差异。结果:两组病例术后骨折愈合情况良好;共有7例术后有咬合干扰,调磨后恢复正常;2例术后感染;术后8周X片显示加压内固定组骨折愈合改建基本完成,优于非加压内固定组。结论:加压内固定和非加压内固定都完全能达到AO关于内固定的要求,均是下颌骨骨折良好的固定方式,加压内固定技术要求高,但固定理想,骨折愈合更快,临床应用表明加压内固定的骨折愈合早期具有明显的优势。

Two Internal Fixation Comparative Study of Treatment of Mandibular Fractures

Objective: To observe mandibular fracture treatment pressurized and non-pressurized fixed within a fixed period of efficacy and two of the clinical evaluation of a fixed form.Methods: 57 patients with mandibular fractures were divided into two groups,namely non-pressurized and pressurized internal fixation for the treatment of internal fixation.Comparative study of two groups of patients after healing,recovery,X-ray findings and others.Results: The two groups of patients who fracture was healed well;There were seven cases postoperative occlusal interference,regulation and resume normal grinding and two cases of postoperative infection;Pressure within eight weeks after X-rays revealed healing fracture fixation into basically completed.was better than the non-pressurized internal fixation.Conclusion: The pressurized and non-pressurized fixed within a fixed period of AO were fully able to meet the requirements of internal fixation.Might be a good mandibular fracture fixation,internal fixation compression technology,but fixed ideals,fracture healing faster.Clinical application had shown pressure early fixation of fracture healing is an obvious advantage.
