作者对14只尸腕分别采用标准的后前位、手向尺侧和桡侧偏斜的后前位及X 线管由尺侧向桡侧倾斜5°、10°及15°的后前位片。除5只因有疾病被淘汰外,其余9只均行连续的横断及冠状面CT 扫描。在X 线管由尺侧向桡侧倾斜10°、中心线对准腕中央上方的后前位片上,分别在舟月间隙的远部、近部及中部测量舟状骨和月状骨间的距离,这种方法可使X 线束与舟月间平行,使入投影最佳。在横断CT 扫描,为了不使舟骨和月骨重叠,需要测量X线束通过舟月间隙最小和最大间的角度。为评价舟月间隙精确的解剖,解剖了3只腕。作者见到横断及冠状CT 扫描象及标本的解部均说明舟骨和月骨虽有软骨复盖,使舟状骨的近端形成一小的半月状
The authors used a standard anteroposterior position on 14 dead bodies, posterior anterior and X-ray tubes skewed from the ulnar side to the radial side by 5 °, 10 ° and 15 ° to the ulnar and radial extents, respectively sheet. In addition to 5 were eliminated because of disease, the remaining 9 were performed continuous transection and coronal CT scan. The X-ray tube was tilted 10 ° to the radial side from the ulnar side, the center line was aligned with the posterior anteroposterior of the wrist center, and the distance between the scaphoid and the lunate was measured at the distal, proximal and middle of the scapholunate space Distance, this method allows the X-ray beam parallel to the boat during the month, so that the projection into the best. In a transection CT scan, in order not to overlap the scaphoid and the lunate bone, it is necessary to measure the angle between the minimum and maximum X-ray beam passing through the scapholunate gap. To evaluate the exact anatomy of the scapaculum, three wrists were dissected. The author saw the transected and coronal CT scans and specimens of the Ministry of Solutions are illustrated scaphoid and lunate although the cartilage covered, so that the proximal scaphoid form a small semilunar
