改良梅花髓内针治疗胫腓骨骨折的疗效评价

Treatment of fracture of tibia and fibula with modified cloverleaf type intramedullary nail

目的分析改良梅花髓内针治疗胫腓骨骨折的可行性.方法自1993年7月～2000年5月,我院应用改良梅花髓内针治疗226例胫腓骨骨折,并对其骨折的类型、手术方法、术后处理及疗效进行总结和分析.结果 180例获得随访,随访时间6个月～6年,平均26个月,除9例延迟愈合,2例不愈合外,余均正常骨性愈合,按Johner-Wruh评分标准,优125例,良40例,中12例,差3例,优良率91.6%.结论该方法具有创伤小、固定可靠、应力遮挡小、可有效地抗旋转作用等优点,其生物力学特性适合胫骨骨折愈合的需要.

ve To study the treatment of fracture of tibia and fibula with modified cloverleaf type intramedullary nail Methods From 1993. 7 to 2000. 5,226 cases of fracture of tibia and fibula were treated with modified cloverleaf type intramedullary nail and the fracture type, operative method, postoperative man-agement and clinical results of the cases were analysed. Results 180 cases were followed up from 6 months to 6 years, with an average of 26 months. All the cases had normal bony union except 9 cases of delayed union and 2 of non-union. According to Johner-Wruh's grading standard, excellent results were obtained in 125 cases, good in 40, fair in 12 and poor in 3, with excellent and good ratio of 91.6%. Conclusion This treatment method is of merits of minimal incision,stable fixation,small stress shielding,effective in resisting rotation and its biomechanic characteristics meet the requirement of tibia fracture union.
