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 study the X-ray anatomical characteristics of the tibia medullary cavity of Uygur normal adults and to provide morphological evidence for clinical application. Methods: The normal and lateral radiographs of the right lower leg of 30 normal Uighur adults were taken. The total length of the medullary cavity of the tibia, the length of the narrow segment, the fixed point of the inferior segment, the sagittal and transverse diameters, the sagittal and transverse diameters of the sagittal plane, Bone marrow cavity arc and a series of related parameters were measured and statistically processed. Results: There was no significant difference in the parameters of the tibial medullary cavity of 30 Uighur normal adults (P> 0.05). The total length of the tibia medullary cavity was (30.6 ± 2.5) cm and the tibia The length of the medullary cavity was (8.0 ± 0.6) cm, the index of the medullary cavity was 11.7 ± 4.6, the index of the medullary cavity was 8.9 ± 2 .7, the curvature of the medullary cavity of the tibia was 2 .7 ° ± 0 .4 °. CONCLUSION: There are no gender differences in the parameters of the tibial medullary cavity in Uygur normal adults, with racial differences; ethnic differences should be considered in the selection of intramedullary nailing for the treatment of tibial fractures.
