锁定钢板辅助固定治疗股骨髓内钉术后骨不连

目的 :探讨有限切开应用锁定钢板辅助髓内钉治疗股骨干髓内钉术后骨不连的临床疗效。方法 :回顾性分析2006年1月至2015年12月采用有限切开方式锁定钢板辅助固定治疗的40例股骨骨折髓内钉固定术后骨不连患者的临床资料,其中男22例,女18例;年龄21~60岁,平均(35.0±2.2)岁。骨不连时间为9~24个月,平均(14.1±1.5)个月。观察患者的手术时间、术中出血量、住院时间、并发症、骨折愈合时间、膝关节功能恢复情况,并采用Evanich评分标准对其临床疗效进行评价。结果:40例患者均获随访,时间12~24个月,平均(15.2±2.7)个月。手术时间105.1~130.2 min,平均(112.5±10.2)min;术中出血量207.0~250.2 ml,平均(220.6±14.7)ml;住院时间10~15 d,平均(12.2±1.5)d。患者在附加钢板固定术后4~12个月获得骨性愈合,平均愈合时间(6.2±1.9)个月。术后未出现内植物失效、感染等并发症。根据膝关节Evanich评分:总分83.2±5.6,优22例,良17例,中1例。结论:股骨干髓内钉术后出现骨不连应用有限切开锁定钢板辅助原有髓内钉固定疗效显著,增加了骨折端的稳定性,为骨痂生长提供了稳定的环境,治愈率高,术后创伤小,并发症少,可以尽早功能锻炼,促进膝关节功能恢复良好。

Interlock plate fixation for the treatment of femoral hypertrophic nonunions after intramedullary nailing fixation

Objective: To investigate clinical effect of locking plate assisted intramedullary nail in treating femoral hypertrophic nonunions after intramedullary fixation.Methods: From January 2006 to December 2015,clinical data of 40 patients with femoral nonunions after intramedullary nail internal fixation treated with interlock plate internal fixation were respectively analyzed. Among patients,there were 22 males and 18 females,aged from 21 to 60 years old with an average age of (35.0±2.2) years. The time of bone nonunion ranged from 9 to 24 months with an average of (14.1±1.5) months. Operative time,blood loss,hospital stay,complications,bone healing time and recovery of function were observed,Evanich scoring was applied to evaluate clinical effects.Results: All patients were followed up from 12 to 24 months with an average of (15.2±2.7) months. Operative time ranged from 105.1 to 130.2 min with an average of (112.5±10.2) min;blood loss ranged from 207.0 to 250.2 ml with an average of (220.6±14.7)ml; hospital stay ranged from 10 to 15 days with an average of (12.2±1.5) d. All patients were obtained bone healing from 4 to 12 months after additional plate internal fixation,with an average of (6.2±1.9) months. No implant failure and infection occurred after operation. According to Evanich scoring of knee joint,total score was 83.2±5.6,22 cases obtained excellent results,17 good and 1 fair.Conclusion: Limited incision approach locking plate with original intramedullary nail fixation for femoral hypertrophic nonunions subsequent to intramedullary fixation could receive good results,increase stability of fracture,and could increase stability of fracture,provide environment for callus growth. It had advantages of high cure rate,less trauma and complications,and also could do functional exercise earlier to promote good recovery of knee joint.
