摘要
目的 :探讨用Ilizarov微创技术矫正各种类型膝关节屈曲畸形。方法 :在Ilizarov牵伸器基础上 ,研制了新型膝关节牵伸器 ;包括股骨、胫骨骨外固定器 ,并在膝关节两侧由关节铰链连接。术中安装时确定膝关节伸屈的旋转中心 ,用于伸缩的带弹簧牵伸杆安装在膝后的上下两个钢环上 ,手术中将牵伸器用 2mm克氏针交叉穿股骨和胫骨于膝关节中央 ,术后逐渐旋转牵伸杆 ,膝关节软骨面在避免挤压的情况下慢慢伸直。结果 :2 7例 3 0个膝关节 ,术后平均牵伸时间 5 8d ( 18d~ 10个月 ) ,全部病例膝关节伸直皆达到矫形需要的要求 ,未发生影响治疗效果的并发症。结论 :新型Ilizarov膝关节牵伸器的研制和临床应用技术 ,开辟了一条微创、简便、安全治疗屈膝挛缩的有效方法 。
Objective:To explore minimally invasive technique for correcting various flexion knee abnormalities.Method:Based on the Ilizarov's distraction apparatuses of the joints,a new type instrument was created.It included the femoral and tibial external fixation instruments with two rings,they were connected on the two sides of the knee through two hinges,and the threaded rods behind the knee.The rotational center of the knee joint was proved during the operation.The threaded rods worn springs were installed on the upper and lower rings behind the knee,the apparatus was fixed on the femur and tibia through the cross 2mm k-wires.After the operation,the telescopic rods were rotated,the knee of flexion contracture slowly got straight under no compression of the articular cartilage.Result:Twenty-seven patients with 30 knees,averaged postoperative distraction time were 58d (18d~10months).All the patients' effect was satisfactory,no complications influencing treatment.Conclusion:The new type Ilizarov distraction apparatuses of knee joint are the minimally invasive,simple,safe,effective methods and technique,which treat the flexed contracture of the knee,and can also correct the serious flexed malformations of knee which can be difficultly corrected by the traditional operations.
