Clinical application of spinous process forming in posterior lumbar interbody fusion / 中国矫形外科杂志

ABSTRACT

[Objective]To explore the feasibility and clinical effects of spinous proscess forming in posterior in the treatment of lower lumbar diseases. [Methods]Seventy-seven cases suffered from lower lumbar diseases were treated using spinous proscess forming as interbody fusion material.The cases included 35 of lumbar disc herniation,21 of spondylolysis,11 of degenerative spondylolisthesis and 10 of spinal canal stenosis.The clinical data and imaging results were investigated.[Results]Seventy-two patiens were followed up for 1 to 2 years while 5 were lost.During following-up,no loosened internal fixation,broken nail or stick,infravertebra prolapsed,or detachment recurrence was found.Preoperative the height of intervertebral space was 8.5?1.9 mm,10.9?1.8 mm at 2 weeks postoperatively and was 10.7?1.7 mm at last follow-up.The height of intervertebral space were significantly increased postoperatively with statistically significant difference(P
