摘要:

背景:儿童弹性髓内钉为具有特定弹性带有弯头的金属圆条结构,是由成人长骨干骨折治疗中使用的髓内针经过发展、演化、改进而来,属于儿童骨折微创治疗方法,作为髓内固定器械,它对于儿童长骨骨折有着足够的固定强度,同时又可以促进骨折部位微动,从而促进骨折部位的愈合,目前已成为治疗儿童长骨骨折的一种新型的内固定材料。
目的:回顾性总结评价弹性髓内钉微创内固定修复儿童长骨干骨折的临床效果。
方法:自2010 年1月至2014年4月采用弹性髓内钉置入内固定修复儿童长骨干骨折30例,其中股骨4例,胫腓骨骨折11例,肱骨4例,尺桡骨双骨折7例,尺骨骨折3例,桡骨1例,均为新鲜闭合骨折;男21例,女9例;受伤年龄5-16岁,平均9.6岁;23例为闭合复位,7例因闭合复位困难,行小切口有限切开复位。观察患儿的骨折复位情况、手术时间、骨折愈合时间、内固定后功能恢复情况、Flynn髓内钉疗效、内固定后并发症和不良事件。
结果与结论:30例患儿手术时间25-65 min,平均51 min,所有骨折都获得良好的复位。随访6-12个月,骨折均顺利愈合,愈合时间8-16周,平均12周,Flynn髓内钉疗效优良率为100%,患肢功能恢复正常,无并发症发生。证实该方案具有切口小、不需要剥离骨膜、软组织损伤小、手术时间短、感染率低、生物力学稳固、功能恢复快、愈合快、并发症少等优点,其设计上重视儿童骨折特点和骨组织的生长发育规律,特别适合儿童长骨骨折的内固定治疗。

Abstract:

BACKGROUND: Elastic intramedullary nail for children with specific elastic with bend round metal strip structure, is based on adult long bone fracture treatment using intramedullary needle through the development, evolution and improvement, and has become the minimally invasive treatment method in children with fractures. As a intramedullary fixation device, it has sufficient fixing strength for children long bone fractures, simultaneously can promote jiggling at the fracture site, finally contribute to fracture healing. At present, it has been a novel fixation material for treatment of children long bone fractures.
OBJECTIVE: To retrospectively summarize and evaluate the clinical outcomes of elastic intramedullary nail internal fixation for the treatment of children with long bone shaft fracture using minimally invasive surgery.
METHODS: From January 2010 to April 2014, 30 children with long bone shaft fractures were treated with elastic intramedullary nail fixation, including 4 cases of femur, 11 cases of tibia and fibula fractures, 4 cases of humerus, 7 cases of ulnar and radial fractures, 3 cases of ulnar fractures, and 1 case of radial fracture. All cases were fresh closed fracture. There were 21 males and 9 females. Their age at injury was from 5 to 16 years old, averagely 9.6 years. 23 cases received closed reduction, and 7 cases received limited small incision reset due to difficult closed reduction. Fracture reduction, operation time, healing time, functional recovery after fixation, curative effects of Flynn intramedullary nail, post-fixation complications and adverse events were observed in children. 
RESULTS AND CONCLUSION: Operation time was between 25 and 65 minutes in 30 children, averagely 51 minutes. All fracture sites were reduced. All patients were followed up for 6-12 months. All fractures were healed, and the healing time ranged from 8 to 16 weeks, averagely 12 weeks. The excellent and good rate of Flynn intramedullary nail was 100%. The function of affected limbs recovered to normal. No complication occurred. The technology has the advantages of small incision, no need to strip periosteum, minor soft tissue injury, short operation time, low infection rate, biomechanical stability, quick functional recovery, fast healing, and less complications. Its design focuses on children fracture characteristics and growth rule of bone tissue, and is very suitable for long bone fracture fixation.
