线捆绑游离皮质骨块包裹松质骨植骨治疗胫骨节段性骨缺损疗效

Effect of cancellous bone graft with free cordical bone blocks and line bonding for tibial segmental bone defect

摘要:

目的  评价线捆绑游离皮质骨块包裹松质骨植骨治疗胫骨节段性骨缺损的效果。方法  回顾分析治疗胫骨节段性骨缺损35例，其中采用线捆绑游离皮质骨块包裹松质骨植骨治疗15例设为试验组，采用传统方法植骨或ILIZAROV技术治疗20例设为对照组。比较愈合时间、骨愈合分级、并发症、患肢功能恢复和关节活动度恢复情况。结果  患者获12～48个月、平均18.6个月随访。骨缺损均愈合。试验组的愈合时间和并发症少于对照组，差异有统计学意义（P <0.05），两组的骨愈合分级、临近关节活动度和功能恢复比较，差异无统计学意义（P >0.05）。结论  利用线捆绑游离皮质骨块包裹松质骨植骨修复节段性骨缺损，方法简便，愈合较快，愈合率高，并发症少，但也有适应证等方面局限性。

Abstract:

Objective To evaluate the therapeutic effect of cancellous bone graft wrapped using free cortical bone blocks and line bonding for repairing tibial segmental bone defects. Methods A total of 35 cases with tibial segmental bone defects were retrospectively studied, 15 cases were performed cancellous bone graft using free cortical bone blocks and line bonding as test group while 20 cases were performed traditional bone graft or Ilizarov technique as control group. The healing time, healing grade, complications, functional recovery and range of movement of joint of limbs were compared. Results The patients were followed up for 12 to 48 months, average 18.6 months. All bone defects were healed. The healing time and complications in the test group were less than those in the control group, there were significant differences between two groups (P ＜ 0.05). No significant differences were found in the healing grade, functional recovery and range of movement of joint between two groups (P ＞ 0.05). Conclusions Cancellous bone graft wrapped free cortical bone blocks and line bonding for repairing tibial segmental bone defects is simple, with fast healing and high healing rate, but also has limitations in indications and so on.
