摘要
目的:探讨舟状骨显示较为理想的X线DR投照体位,提高平片对舟状骨骨折的诊断准确性,降低舟状骨骨折并发症的发生率。方法:选取健康志愿者2例(男女各1例),分别对腕关节采用不同体位进行投照。根据舟状骨显示情况对投照体位进行评分,比较各投照体位对舟状骨的显示情况。另选取志愿者6例,进一步验证上述预实验所优化的投照体位。结果:舟状骨握拳尺偏位、旋前60°和旋后45°斜位片及侧位片可以从不同角度显示舟状骨。结论:舟状骨握拳尺偏位、旋前60°和旋后45°斜位片及侧位相结合是用于评价舟状骨骨折较为理想的X线投照体位。
Objective： To discuss the optimal radiographic positioning of the scaphoid bone of wrist,in order to improve the accuracy for the X-ray plain film diagnosis of scaphoid fracture. Methods： 2 heahhy volunteers with male and fe male for one each were included in this study. X ray fihns were undertaken in different positions and graded according to the demonstration of scaphoid. The optimal positions selected were further taken and evaluated in another 6 volunteers. Results： The positions including ulnar deviation of wrist with fist clenching,oblique view with anterior rotation of wrist in 60° as well as posterior rotation in ,15° and lateral view could display the scaphoid bone in various angles. Conclusion： Ulnar deviation of wrist with fist clenching in combination with lateral view, oblique view with anterior rotation of wrist in 60° and oblique view with posterior rotation of wrist in 45° are the optimal positions in evaluating scaphoid fracture.
