摘　　要：目的观察颌间牵引钉联合可吸收性微型骨接板治疗老年下颌骨骨折的临床效果。方法选取石家庄市第二医院收治的下颌骨骨折老年患者90例,按照治疗方案不同随机分为对照组和观察组各45例。对照组行钛板内固定联合颌间牵引钉外固定治疗,观察组行可吸收性微型骨接板内固定联合颌间牵引钉外固定治疗,比较2组术后下颌骨骨折稳定性(AF-BF距、AXB角)以及临床相关指标、并发症发生率和治疗效果。结果治疗后3个月,观察组下颌骨骨折稳定性提高,AF-BF距、AXB角均高于对照组(P<0.05);观察组下颌骨、整体的最大应力值高出对照组,但固定板最大应力值低于对照组,差异均具有统计学意义(P<0.05);观察组下颌骨、整体、固定板的最大位移值高出对照组(P<0.05);观察组并发症发生率低于对照组(P<0.05);观察组治疗效果好于对照组(P<0.05)。结论颌间牵引钉联合生物可吸收性微型骨接板治疗老年下颌骨骨折效果良好,值得临床推广应用。Objective To observe the clinical effect of intermaxillary traction nail combined with biological absorbable micro plate in the treatment of senile mandibular fracture.Methods Elderly patients with mandibular fracture admitted to Shijiazhuang Second Hospital were selected and divided into control group and observation group according to different treatment plans by random number table method.The control group received internal fixation with titanium plate combined with external fixation with intermaxillary traction nail,and the observation group received internal fixation with biological absorbable micro plate combined with external fixation with intermaxillary traction nail.The postoperative clinical indicators,incidence of complications and therapeutic effect of the two groups were compared.Results Three month after treatment,the AF-BF distance and AXB Angle in the observation group were higher than those in the control group(P<0.05);the maximum stress value of mandible and whole in the observation group was higher than that in the control group,but the fixed plate was lower than that in the control group(P<0.05).Compared with the control group,the maximum displacement values of mandible,whole and fixed plate were higher in the observation group(P<0.05);the observation group had a lower rate of complications than that in the control group(P<0.05);the treatment effect of the observation group was better than that in the control group(P<0.05).Conclusion Intermaxillary traction nail combined with biological absorbable micro plate has significant effect in the treatment of elderly mandibular fractures,which is worthy of clinical promotion and application.
