摘要
目的:观察应用空心加压螺钉内固定加植骨术治疗腰椎峡部裂症的临床疗效。方法:自2003年2月以来,使用空心加压螺钉内固定加植骨术治疗腰椎峡部裂症16例,男10例,女6例,年龄18~54岁,平均32岁。L4椎弓崩裂5例,L5椎弓崩裂11例,均为双侧病变。所有患者均明确主诉腰痛。采用后正中入路,暴露双侧病灶,将峡部裂中的纤维瘢痕组织彻底清除,咬除残端硬化部分至出血为止,髂后上棘取骨行峡部裂处局部植骨。安放空心加压螺钉固定。结果:术后随访14~26月,疼痛症状明显缓解,峡部裂处植骨骨性愈合,未见骨不连及内固定断裂。结论:对于腰椎峡部裂症患者可以采用空心加压螺钉内固定加植骨进行峡部修复,避免脊柱多元节段融合术;空心加压螺钉是一种安全、有效的内固定装置。
Objective:To observe the clinical results of a hollow compression nail applied to treat the lumbar spondylolysis without spondylolisthesis. Methods:Since February,2003,sixteen cases of lumbar spondylolysis without spondylolisthesis have been treated with a hollow compression nail and bone grafting .The mean age of the group was 32,from 18 to 54.Five cases of spondylolysis located at L4 and the other 11 at L5.All the patients suffered from severe back pain.During the operation,the presence of the pars interarticularis defect was confirmed.The defects were cleared of any fibrous and cartilaginous tissues.The sclerotic bone margins were curetted until bleeding was noted .Autograft harvested from posterior ilium was done.The hollow compression nail was placed onto the index vertebra. Results:All the patients were followed-up for more than 14 months (14~26 months).The significant back pain relief was found in all the cases.The bony healing was comfirmed in 11 cases ,and the other 5 were in the process of bone growth. Conclusions:The simple spondylolysis can be treated by the hollow compression nail without spinal fusion.The hollow compression nail is proved to be safe and effective.
