1、经皮撬拨复位内固定联合替代骨填充治疗跟骨关节内骨折作者:倪明,梅炯,俞秀茂,王家骐,李山珠,祝晓忠【摘要】[目的]介绍应用经皮撬拨复位内固定联合可注射人工替代骨填充治疗跟骨骨折的经验和技术要点。[方法]2004年4月~2006年4月,作者采用经皮撬拨复位空心螺钉固定联合可注射型高黏度人工替代骨填充方法,对15例16侧跟骨骨折进行治疗,男13例14侧,女2例2侧;年龄24~61岁,平均36.6岁。术前均摄跟骨侧位、轴位及足斜位X线片,并行CT三维重建检查。骨折按Sanders分型:Ⅱ型14侧(Ⅱa型3侧,Ⅱb型3侧,Ⅱc8侧),SandersⅢac型2侧。术中通过斯氏针垂
2、直穿过跟骨结节牵引恢复跟骨长度,再沿跟骨外侧骨折线做0.5cm切口,用弯组织剪向后上方撬拨复位后关节面。根据骨折类型,选择不同规格的空心松质骨螺钉固定骨折块。最后经切口注入人工替代骨填充跟骨内缺损。[结果]所有患者获得12~34个月(平均18.4个月)随访。术后均未发生切口感染、螺钉断裂及跟骨内翻等并发症。术后平均骨折愈合时间为10周。按美国足踝外科协会(AOFAS)后足评分系统,优12例,良4例,优良率100%。X线片检查示Bhler角、Gissane角、跟骨外形基本恢复正常。[结论]经皮撬拨复位内固定联合可注射人工替代骨填充适用于治疗SandersⅡ、Ⅲ型跟骨骨折
