摘要
目的探讨股骨、胫骨骨折应用交锁髓内钉固定后骨不连的诊断及应用微创内固定系统(LISS)或锁定加压钢板(LCP)治疗其骨不连的临床疗效。方法2003年2月～2004年12月,对7例股骨和胫骨骨折患者髓内钉固定后应用X线或CT扫描观察骨不连情况,并应用LISS或LCP固定+植骨治疗,病程10～49个月,平均23.3个月。结果7例患者获4～16个月(平均9.1个月)随访;骨折均在术后4～6个月牢固连接,平均愈合时间4.7个月,无植入物松动等并发症发生。结论对骨折端较长时间存在骨折线、且骨折局部伴有疼痛症状者要果断进行手术干预,消除骨折端的微动和消灭骨缺损。LISS或LCP因其先进的锁定设计,可有效治疗股骨和胫骨骨不连。
Objective To explore diagnosis of nonunion following intramedullary nailing of femoral and tibial fractures and the treatment of nonunion of femoral and tibial fractures with Less Invasive Stabilization System （LISS） or locking compression plate （LCP） . Methods From February 2003 to December 2004, 7 cases of nonunion after intramedullary nailing of femoral and tibial fractures were diagnosed by X-ray or CT scanning or CT-3D. LISS or LCP fixation and bone grafting were employed to treat the 7 cases of nonunion in the femur and tibia. Their case histories ranged from 10 to 49 （mean 23.3） months. Results All the 7 patients were followed up for a mean of 9.1 （4 to 16） months. The bone union time for all the fractures averaged 4. 7 months （ranging from 4 to 6 months） . No loosening or breakage of the implants occurred in this series. Conclusions The operation should be done for the patients who feel pain in the lower extremities or the fracture line still exists at the fracture ends long time after intramedullary nailing. In order to improve the healing of bone fractures, micromovement and bone defects at the fracture site should be eliminated. Because of its merits in design, the LISS can be used to effectively treat nonunion at the distal femur or the proximal tibia.
