髓内扩张自锁钉治疗胫骨骨折

The clinical effectiveness of intramedullary expanded self-locking nail for the treatment fracture of tibia

目的 观察髓内扩张自锁钉(IESN)治疗胫骨骨折的临床疗效。方法 本组25例,其中男17例,女8例;螺旋型及长斜型骨折18例,蝶型骨块粉碎型4例,短斜型3例。闭合性骨折18例,开放性骨折7例(按Gustilo分型:Ⅰ型6例,Ⅱ型1例)。所有患者均采用髓内扩张自锁钉内固定。结果 随访时间6个月～1.5年,术后无感染及断钉。髓内扩张自锁钉固定治疗胫骨骨折,平均骨折愈合时间4.5个月,无畸形愈合,按Johnerwruh评分标准全部达到优良水平。结论 髓内扩张自锁钉固定坚强持久,无应力遮挡,提高了疲劳极限,且操作简单,手术时间短,组织损伤小, 愈合时间短,是较理想的固定方法,适宜于向基层医院推广。

Objective To observe the results of patients with fracture of tibia treated withintramedullary expanded self-locking nail ( IESN) internal fixation.Methods Twenty five patients ,17 male and 8 female with fracture of tibia were treated operatively using IESN internal fixation.Results The follow-up ranged from 6～18 months (average 10 months), all cases healed up without malunion.The average fracture healing time was 4.5 months. According to Johnerwruh evaluation method,allpatients were classified as excellent.Conclusion IESN can improve the fracture healing throughprotecting the clotting blood around the fracture and periosteal blood supply.IESN can be used widelyin fracture of tibia for simple procedur with short time of operation and healing.
