Objective to evaluate the clinical effect of single vertebra reduction fixation system plus isthmic bone grafting on treating lumbar spondylolysis 摘要目的评价单椎体内固定峡部植骨融合治疗腰椎峡部裂的临床疗效。
N o mal healing were observed in all the 7 cases , absorption and poor healing at bot h ends of the graft were not found , too 所有7例煮沸肿瘤骨均获正常骨愈合，与活骨端相连接的植骨两端未见煮沸肿瘤骨吸收或愈合不良。
If associated with osteomyelitis , irrigating and flap grafting was used to control infections and bone grafting followed 单纯骨折不愈合病例均予髓内、外植骨；合并骨髓炎则予以冲洗及皮瓣移植控制感染，二期行植骨手术。
Advantage of the method includes increasing immediate stabilization of the fused segment , improving fusion rate and benefiting rehabilitation 该方法的优点是：达到了固定阶段即时稳定性，提高了植骨融合率，有利于康复。

Conclusion the method used for direct repair of the defect of the pars interarticularis in this patients proved to he simple and effective 结论单节段峡部植骨椎板钩固定是治疗腰椎峡部不连性下腰痛的一种简单有效的方式。
Consequently , if shortening will not be too great , the defect should be obliterated , and the fragments should be apposed before the grafts are applied 因此、如果短缩不是太多，在植骨前应先将骨块对位，避免出现骨缺损。
The most frequent mistreating is curettage for a malignant lesion based on a misdiagnosis , such as osteomyelitis , fibrodysplacia , gct , cyst , etc 对恶性骨肿瘤给予刮除植骨.该类错误治疗的原因多是误诊为骨髓炎、纤维结构不良、骨巨细胞瘤或囊肿等。
