目的:介绍10年间应用半环槽式外固定器治疗儿童严重胫骨开放性骨折的经验,并评价其疗效。方法:本组14例,年龄4～14岁,平均9岁,按 Gustilo 骨折分类,Ⅱ°1例,Ⅲ°_A2例,Ⅲ°_B8例,陈旧性骨折伴伤口感染,骨及软组织缺损3例。对不同骨折类型的固定方法进行了详细的介绍。结果:术后随访11例,随访时间20个月至9年,无骨不连、再骨折及骨骺早闭,关节活动满意。功能恢复好。6例发生伤肢过度生长,但均<1.4cm。结论:骨外固定于骨折区外穿针固定,不干扰骨折端的血循环;无内固定物的置入,减少了感染机率;其固定强度的可调性及稳固的固定有利于术后早期功能锻炼。对严重开放性骨折,脑外伤肌张力升高及多发伤者更为适用。
OBJECTIVE: To introduce the experience of applying semi-annular external fixator in 10 years to treat open tibial fractures in children and to evaluate its curative effect. Methods: The group of 14 patients, aged 4 to 14 years old, average 9 years old, according to Gustilo fracture classification, Ⅱ ° 1 case, Ⅲ ° _A2 cases, Ⅲ ° _B8 cases of old fracture with wound infection, bone and soft tissue defects in 3 cases . The different fracture types of fixation methods are described in detail. Results: Eleven patients were followed up for 20 months to 9 years. No bone nonunion, then fracture and epiphyseal early closure, joint activity was satisfactory. Function recovery is good. 6 cases of excessive growth of injured limbs, but all <1.4cm. CONCLUSIONS: External fixation of the bone outside the fracture area through the needle does not interfere with the blood circulation at the fracture end. With no internal fixation, the probability of infection is reduced. The adjustable fixation and firm fixation are beneficial to early postoperative functional exercise . For severe open fractures, brain injury increased muscle tension and multiple injuries are more applicable.
