30例正常维吾尔族成人胫骨骨髓腔的X线解剖及其临床意义

Applied anatomy of the tibial medullary cavity and its clinical significance of Uigur nationality in Xinjiang

目的:研究维吾尔族正常成人胫骨骨髓腔的 X线解剖特征 ,为临床应用提供形态学依据。 方法 :拍摄30例正常维吾尔族成人右侧小腿正、侧位片 ,对胫骨骨髓腔全长、狭段长、下段定点高、出入口矢状径和横径、狭点矢状径和横径及骨髓腔弧度等一系列相关参数进行测量并进行统计学处理。 结果 :30例维吾尔族正常成人胫骨骨髓腔各参数间无性别差异 (P >0 .0 5 ) ;男女合为一组得胫骨骨髓腔全长为 (30 .6± 2 .5 ) cm,胫骨骨髓腔狭段长度为 (8.0± 0 .6 ) cm,髓腔上开口指数为 11.7± 4 .6 ,髓腔下开口指数为 8.9± 2 .7,胫骨髓腔中心线向后的弧度为2 .7°± 0 .4°。 结论:维吾尔族正常成人胫骨骨髓腔各项参数间无性别差异 ,有种族差异 ;选择髓内钉固定治疗胫骨骨折时 ,应考虑种族差异。

Objective: To provide morphological basis for application by investigating the morphological characteristics of tibial medullary cavity of Uigur nationality in Xinjiang. Methods: A serial parameters were defined and measured on the X-ray photos of right tibias of 30 Uigur adults (male 15,female 15). Results: There were no differences of parameters between male and female ( P >0.05). The total length of tibial medullary was 30.6±2.5 cm,and the length of narrow part was 8.0±0.6 cm. The proximal and distal opening K were 11.7±4.6 and 8.9±2.7 respectively. The arc of the middle line of medullary cavity was 2.7°±0.4°. Conclusions: The parameters have no differences between male and female,but have differences between Uigur and Han nationalities. The differences of parameters of Uigur and Han nationalities should be taken into account as factor for intramedullary nail fixation to treat the fracture of tibia.
