Digital anatomy of lumbar spinous process tilt angle of adults in northeast China:prodinding reference for pedicle screw insertion
摘要
Abstract
BACKGROUND:Posterior lumbar fusion using pedicle screw-rod system fixation is the main surgical method for various lumbar diseases, and the accuracy of pedicle screw insertion is the key to success. Spinous processes are superficial in position, which serve as a anatomical landmark providing significant reference. OBJECTIVE: To analyze the anatomical classification of spinous process tilt of adult in northeast China, and to discussthe feasibility of it as the reference of anatomical landmark in pedicle screw fixation.METHODS: The tilt angle of spinous processes of 97 adults in northeast China was measured, and spinous processes of lumbar vertebrae were then classified. All subjects underwent simulative operation to determine the optimal insertion angle,measure the angle between pedicle screw and the spinous process, or standard sagittal plane for comparative analysis.RESULTS AND CONCLUSION: (1) The results were as follows: the distribution of type I was 75.1%, and 20.9% of typeII, 2.3% of type III, 1.7% of type IV. Moreover, there were no significant differences in the angle between pedicle screwand the spinous process, or standard sagittal plane. (3) These findings suggest that lumbar spine angle varies in different individuals, which shouldbe defined through relative examinations. Additionally, spinous process can be a reference inpedicle screw inserting operation.关键词
