摘要
目的应用T_(10)至L_(5)新鲜干燥椎体标本行椎弓根(管)至压缩愈合椎体终板外植骨轴线的设计,用于压缩愈合椎体前柱终板外植骨。方法应用16具T_(10)至L_(5)新鲜干燥椎体标本的椎弓根及侧面椎体测量椎弓根(管)椎体轴线长度、椎弓根(管)内矢径、椎体矢径、椎弓根(管)椎体轴线位置(f角)。椎体前柱压缩程度分度方法:Ⅰ°为椎体前柱压缩1/4内,Ⅱ°为1/4~2/4,Ⅲ°为2/4~3/4,Ⅳ°为3/4以上。利用入端的Saillant描述的f角±(记录为f角±度数),使其出现角度线对应压缩愈合椎体终板变为植骨轴线,形成f角±出现角度线,角度线对应压缩骨折终板为植骨轴线。结果f角为8°~10°时,植骨轴线可对应于椎弓根(管)椎体轴线上终板侧的Ⅱ°压缩愈合椎体终板外;f角为16°~18°时,植骨轴线对应于Ⅰ°压缩愈合椎体终板外;f角为-10°~-8°时,植骨轴线对应于椎弓根(管)椎体轴线的下终板侧的Ⅲ°压缩愈合椎体终板外;f角为-18°~-16°时,植骨轴线对应于Ⅳ°压缩愈合椎体终板外。结论以设计的T_(10)至L_(5)椎弓根(管)至压缩愈合椎体终板外植骨轴线植骨,可满足粒骨植入并因椎弓根(管)周围皮质骨坚韧,术式安全、简易。
Objective To anatomically study the external bone graft axis from the pedicle(canal)to the endplate designed for compression healing fractures of the anterior vertebral column in freshly dried vertebral specimens from T_(10) to L_(5).Methods Eight groups of freshly dried vertebral specimens from T_(10) to L_(5)(128 vertebral bodies and 256 lateral pedicles and lateral vertebral bodies)were used to observe the vertebral axis of the pedicle(canal),the internal sagittal diameter of the pedicle(canal),and the sagittal diameter of the vertebral body,and the position of vertebral pedicle(canal)axis(f-angle)before design of the external bone graft axis from the pedicle(canal)to the endplate of the compression healing vertebral body.(1)The internal sagittal diameter of the pedicle(canal)was divided into 3 segments.The lateral segment of the vertebral plate was wide,the middle segment of the isthmus of the vertebral arch was narrow and the medial segment of the terminal segment of the vertebral arch was wide.The narrow isthmus of the middle arch(canal)was used as a transposition axis in the design of the axis of the bone graft from the vertebral arch(canal)to the endplate of the compression healing vertebral body.(2)The axis of the vertebral body of the pedicle(canal)was located medial to the transposition axis,parallel to the f-angle at 0°as described by Saillant G.(3)The compression degree of the vertebral body was measured at the outer edge of the lateral anterior column,withⅠ°for less than 1/4 compression of the anterior column of the vertebral body,Ⅱ°for 1/4 to 2/4,Ⅲ°for 2/4 to 3/4 andⅣ°for more than 3/4 of the compression.(4)The f-angle described by Salliant G at the entry end which was corresponding to the endplate of the compression healing vertebral body was used to design the pedicle(canal)to the outer implant axis of the endplate of the compression healing vertebral body.Results At an f-angle of 8°to 10°,the bone graft axis was aligned with theⅡ°compression healing vertebral endplate on the su
