摘要

35 www.wjir.org摘要-对于因各种原因需要内固定的患者,椎弓根形态测量学知识对于外科医生成功应用手术螺钉的能力非常重要。考虑到错误放置椎弓根螺钉可能产生比实际损伤本身更严重的并发症,这一点更加重要。通常表现为脊髓或神经根损伤、椎弓根骨折、血管损伤、脑脊液漏等。本研究采用土壤和水浸渍法制备的成人椎体共185块。共有34对雄性和3对雌性。从L1到L5椎弓根的长度和厚度在颅侧增加,但这没有统计学意义。观察到蒂宽度以类似的方式增加。雌虫的蒂值高于雄虫,最小为8.25 mm。该研究得出结论,椎弓根尺寸在人群和性别之间存在差异,并建议在腰椎手术前进行适当的术前评估和评估。

Morphological Characteristics of Lumber Pedicle: A Study of Adult Nigerian Cadaver
35 www.wjir.org  Abstract— Knowledge of pedicle morphometry is important in the surgeons’ ability to successfully apply a surgical screw to the spine of patients who need instrumentation for various reasons. This is more so considering that a wrongly placed pedicle screw can produce complications worse than the actual injury itself. Often these may present as spinal cord or nerve root injuries, pedicle fractures, vascular injuries, leakage of cerebrospinal fluid among several others. A total of 185 adult lumber vertebrae, prepared through soil and water maceration were used in this study. There were 34 sets of males and three sets of females. Craniocaudal increase was noted in Pedicle length and thickness from L1 to L5 but this was not statistically significant. Pedicle width was observed to increase in a similar manner. Females had higher pedicle values than their male counterparts and the least was 8.25 mm. The study concludes that pedicle dimensions vary among population and between sex and recommend proper pre-operative evaluation and assessments prior to surgical instrumentation on the lumbar spine.
