AO钢板、矩形髓内钉、带锁髓内钉治疗胫骨骨折的比较

目的探讨胫骨骨折内固定物的临床疗效。方法采用ＡＯ钢板治疗５２例，矩形髓内钉１６例，带锁髓内钉３６例，并进行临床随访分析。结果骨折愈合时间ＡＯ钢板组平均８个月，矩形髓内钉组９个月，带锁髓内钉组６个月。ＡＯ钢板组发生伤口感染３例，延迟感染１例，钢板松动３例；矩形髓内钉组发生畸形愈合２例；带锁髓内钉组发生伤口感染１例，远端锁钉松动１例，膝关痛１例。结论带锁髓内钉为轴性及弹性内固定，内固定坚强，为闭合或半

Comparison of treatment of the tibia fractures with AO plate, square intramedullary nail and interlocking nail

Objective\ To explore the clinical effect of internal fixation devices in treatment of tibia fractures.Methods\ There were 52 patients treated by AO plate,16 cases by square intramedullary nail, and 36 cases by interlocking nail.All the patients were followed up.Results\ Union occurred at an averaged time of 8 months, 9 months, 6 months respectively in AO plate, square intramedullary nail and interlocking nail.In AO plate group there were wound infection in 3, delayed infection in 1, plate loosening in 3; there was 1 case of deforming union in square intramedullary nail group; and in interlocking nail group there were wound infection in 1, distal screw loosening in 1, and painful knee in 1 case. Conclusion\ Interlocking nail is axial, elastic and it is the most solid internal fixation devices,and it is a semi closed operation with less operative trauma.It should be firstly choosen in patients with open or unstable fracture.
