DVR解剖型桡骨掌侧锁定接骨板置入内固定治疗桡骨远端C型骨折：与普通掌侧接骨板的比较

背景：纵观目前治疗粉碎及不稳定桡骨远端骨折的各种方法,金属材料桡骨掌侧锁定接骨板的优点日益突出。目的：观察DVR解剖型桡骨掌侧锁定接骨板置入内固定治疗桡骨远端AO分型C型骨折的效果。方法：纳入AO分型桡骨远端C型骨折患者51例,根据其意愿及经济状况非随机分为2组,实验组27例应用DVR解剖型桡骨掌侧锁定接骨板,对照组24例应用普通掌侧接骨板。对比两组患者在手术时间、术中C臂透视次数,术中接骨板安装次数,正中神经炎发生、术后腱鞘炎发生、腕关节功能恢复时间6个方面的差异。结果与结论：实验组X射线片显示骨折全部Ⅰ期愈合,均无感染、骨不连、钢板松动、正中神经炎等并发症。和同期普通掌侧接骨板治疗方法相比,具有明显的优势,Mcbride腕关节功能恢复优良率明显高于对照组（P〈0.001）。提示使用DVR解剖型桡骨掌侧锁定接骨板置入内固定治疗桡骨远端C型骨折具有操作更加便捷,安全可靠,完全解剖复位,固定坚强,可早期进行功能锻炼,关节功能恢复优良等优点。

DVR system versus palm plate for internal fixation of C-type distal radius fractures

BACKGROUND：Looking at the current therapies for comminuted and unstable fractures of the distal radius,metal locking plate becomes prevalent.OBJECTIVE：To observe the effect of DVR system on internal fixation of C-type distal radius fractures classified according to AO classification.METHODS：Fifty-one patients with C-type distal radius fractures were assigned into two groups according to their will and economic conditions：DVR（n=27） receiving DVR system fixation and control group（n=24） undergoing palm plate fixation.The following parameters were compared between the two groups：time of operation,number of patients receiving intraoperative C-arm fluoroscopy,number of times to install bonding plates during the operation,occurrence of median neuritis,incidence of postoperative tenosynovitis,and time to recover wrist function.RESULTS AND CONCLUSION：The results of X-ray showed that all the cases in the DVR group were healed without infection,bone nonunion,plate loose and median neuritis.As compared with the control group,the excellent and good rates of wrist function recovery were higher in the DVR group according to Mcbride scoring（P 0.001）.It is indicated that it is simple,safe and reliable to treat C-type distal radius fractures with DVR system with good recovery of joint function.
