Abstract:

Objective To measure the structures relevant to the spondylolysis process and isthmus of the lower lumbar spine by using the imaging method, and to analyze the new lumbar posterior planting bone surgery operation in the process of the safety range and the patients with the relationship between the height and weight. Methods Lateral lumbar spine X-ray images were collected from 300 normal adult males and females, 150 each. The width, length, depth, the spondylolysis depth, graft length and absolute depth of the superior articular process of the 3rd-5th lumbar vertebral were measured with the Digimizer software. The equation of linear regression method was used to analyze these indicators and the patients’height and weight. Results The width, length, depth and the depth of spondylolysis and absolute depth of the articular process, and patients’weight and height in both males and females were not correlated (P> 0.05). There was a significant correlation between planting bone bed length and height (P< 0.05), but not the weight (P> 0.05). Conclusion The image method measuring the lower lumbar spine on the joints and outstanding spondylolysis anatomical structure related to posterior lumbar for bone graft operation provides accurate and reliable operation data.
