腰椎椎体前融合术用于治疗椎体滑脱和椎间盘脱出有许多优点,包括良好的骨性融合率、维持脊椎的稳定性和正常的椎间隙、可切除足够的变性椎间盘、不伤及脊髓和神经根以及早期离床行走等。但由于术后不可能用常规平片或断层来分析脊椎椎管内变化,故作者研究了1985年～1989年间10例椎间盘脱出和13例椎体滑脱者行此种手术的术前与术后的CT变化。男性11例,女性12例,年龄19～60岁,平均随访17.6个月。在同一层面及相同角度行术前和术后CT检查,层厚3mm。术后6～8个月复查CT以评
Lumbar vertebral body anterior fusion for the treatment of vertebral body spondylolisthesis and prolapse have many advantages, including good bone fusion rate, maintain the stability of the spine and normal intervertebral space, can be removed enough degeneration of the intervertebral disc, does not hurt the spinal cord and Nerve root and early walking out of bed and so on. However, due to the postoperative can not be used to analyze the plain film or the spinal changes in the spinal canal, so the author studied in 1985 to 1989, 10 cases of disc herniation and 13 cases of vertebral spondylolisthesis surgery before and after surgery CT changes. 11 males and 12 females, aged 19 to 60 years, with an average follow-up of 17.6 months. Preoperative and postoperative CT examination was performed on the same level and at the same angle with a layer thickness of 3 mm. Postoperative 6 to 8 months to review CT to comment
