摘要
目的：观察后入路植骨融合术治疗退行性腰椎滑脱的疗效。方法：应用保留棘突和部份椎弓的椎板开窗减压，加Ｈ型棘突间及椎板植骨融合术，治疗退行性腰椎滑脱。临床共治疗１２例，术前均有明显的腰痛及下肢放射痛，其中腰４滑脱９例，腰５滑脱３例。随诊时间１～３年。结果：临床症状均缓解，植骨情况经Ｘ线检查，证实融合效果佳，脊柱稳定性好。结论：改良的Ｈ型植骨治疗退行性变腰椎滑脱，手术创伤小，不稳定的脊柱滑脱没有因手术而造成新的不稳定因素，还有利于植入的Ｈ型骨块嵌插稳定，使植骨融合成功率高，疗效较满意。
Aim:To observe effect of posterior vertebral fusion in treatment of degenerative spondylolisthesis.Methods:Degenerative spondylolisthesis cases were treated by bilateral partial hemilaminectomy preserving spinous process and H shape bone grafting between spinous processes and laminae.Twelve cases with obvious low back pain and sciatica preoperatively were treated, including nine cases of lumbar four spondylolisthesis and three cases of lumbar five spondylolisthesis.The average follow up was 1～3 years.Results:Clinical symptoms of all cases were relieved.X ray examinations confirmed good fusion effect with satisfactory spinal stability.Conclusions:Treatment of spondylolisthesis with modify H shape bone grafting can reduce operative trauma and benefit compact stability of the bone graft which leads to high fusion rate. No any new disability is caused by the operation.So it is a satisfactory method for treatment of spondylolisthesis.
