Distinctive to volar fixed-angle plating of the distal radius, the optimal position of the distal fixed-angle support is in the subchondral bone immediately proximal to the articular surface. Standard intraoperative radiographic imaging of the distal radius during placement of a volar fixed-angle plate does not provide adequate visualization of the subchondral bone-distal support interface. A 45 degrees pronated oblique view is described to address this specific issue of whether volar hardware placed at the immediate subchondral bone level has effectively avoided the radiocarpal joint. This is a quite important radiographic consideration when pursuing the strategy of volar fixed-angle plating of distal radius fractures.
对于桡骨远端掌侧固定角度钢板而言,其独特之处在于,远端固定角度支撑的最佳位置是在紧邻关节面的软骨下骨中。在放置掌侧固定角度钢板时,桡骨远端的标准术中放射成像无法充分显示软骨下骨-远端支撑界面。一种45度旋前斜位视图被描述用于解决在紧邻软骨下骨水平放置掌侧硬件是否有效避开桡腕关节这一特定问题。在采用桡骨远端骨折掌侧固定角度钢板固定策略时,这是一个相当重要的放射学考量因素。
