摘要
１９８２～１９９５年，应用半环槽式外固定器成功的治疗了２１例外伤后感染性胫骨骨不连，并对６例肢体短缩者重建了肢体长度。２１例均采用骨外固定器行骨断端加压固定，所有病例均行腓骨截骨术。合并肢体短缩者６例于同期或二期行胫骨上或下干骺端截骨延长术，以达到肢体长度的均衡。虽有再骨折、针道感染、钢针松动等并发症，但所有骨不连最终均达到愈合，创面感染快速得到控制。骨愈合时间３～１１个月，平均５个半月。肢体短缩者６例均恢复了肢体长度。目前在骨不连的治疗方法中，骨外固定器越来越受到重视，其优点是：（１）牢稳的弹性固定及固定刚度的可调性，应力遮挡率低；（２）远离感染病灶，不干扰骨断端的血循环，利于畸形矫治；（３）方便术后处理；（４）利于早期下床及负重锻炼。
From 1982 to 1995, 21 cases of infected posttraumatic tibial nonunion were treated with external skeletal fixation. Six cases of leg shortening were treated at the same setting or in two stages of metapphyseal osteotomy and bone lengthening. Though there were some complications such as refracture at the original fracture site, pin tract infection and pin loosening etc, union and eradication of infection were achieved within 3-11 months eventually. For the six cases of limb discrepancy, limb shortenings were corrected. The advantages of this method of treatment are: (1)stable and elastic fixation with adjustable rigidity and low stress protection rate, (2)no interference with blood circulation of the bone ends, (3)convenience in nursing care and simultaneous correction of the associated deformities, (4)early mobilization and weight bearing.
