外固定架下带血管蒂腓骨及人工骨泰移植治疗儿童慢性感染性胫骨骨缺损

Chronic tibial defection in children treated with grafting of fibula with vessel pedicles and Lebone under external fixators

目的探讨采用外固定架下带血管蒂腓骨及人工骨泰移植,一期治疗儿童慢性感染性胫骨骨缺损的临床疗效。方法选择慢性感染相对静止期的胫骨骨缺损患儿,彻底清除病灶,取相应长度的带血管蒂的腓骨做支撑,恢复骨长度,用外固定支架固定;用人工骨泰(粉剂)与抗菌素混合填充骨缺损区。共治疗19例。结果15例切口一期愈合,4例切口轻度感染,治疗3～4周后愈合,随访0.5～1.5年感染无复发,骨折愈合满意,肢体功能良好。结论采用外固定架下带血管蒂腓骨及人工骨泰移植等综合手段,一期治疗儿童慢性感染性胫骨骨缺损是可行的,疗效显著,治疗周期缩短,肢体功能良好。

Objective To report one stage treatment of chronic tibial defection in children. Methods 19 children with chronic tibial defection were treated in our department when their infection was at the stage of latency. First their focuses of infection were cleared away. Next a piece of fibula with vessel pedicles whose length was equal to that of the tibial defect was taken as the support to restore the length of the tibia. Then the external fixators were applied and a mixture of antibiotic and Lebone powder was used to fill the defect. Results In 15 cases the incision healed at one stage, slight infection occurred in 4 cases whose incisions healed after treatment of 3 to 4 weeks. Follow-ups of 0.5 to 1.5 years showed that no infection occurred again, bone defects healed well and limb function was satisfactory. Conclusion To treat chronic tibial defection in children at one stage, combined therapy should be applied. Grafting of fibula with vessel pedicles and Lebone under external fixators is a good one, because it can shorten the treatment time at no cost of satisfactory effects.
