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.
