To identify the radiographic correlate of the anatomic safe zone for tibial portal placement.
Cadaveric, anatomic, and radiographic study using twenty cadaveric knees. Kirschner wires were placed in the anatomic safe zone. Anteroposterior and lateral radiographs were taken to evaluate the portal placement.
Anatomy laboratory.
Radiographic measurements of Kirschner wires placed in the anatomic safe zone.
The safe zone for tibial nail placement as seen on radiographs is just medial to the lateral tibial spine on the anteroposterior radiograph and immediately adjacent and anterior to the articular surface as visualized on the lateral radiograph. There is some variance on the anteroposterior radiograph but no variance on the lateral radiograph.
The placement of tibial nails in the superior portion of the tibia in the documented position generates the least risk to the intraarticular structures of the knee.
确定胫骨入口放置解剖学安全区的影像学相关因素。
使用20具尸体膝关节进行尸体、解剖学和影像学研究。克氏针放置在解剖学安全区内。拍摄前后位和侧位X线片以评估入口放置情况。
解剖实验室。
放置在解剖学安全区内的克氏针的影像学测量。
X线片上可见的胫骨钉放置安全区，在前后位X线片上位于胫骨外侧棘内侧，在侧位X线片上紧邻关节面且位于关节面前方。前后位X线片上存在一定差异，但侧位X线片上无差异。
在记录的位置将胫骨钉放置在胫骨上部，对膝关节关节内结构产生的风险最小。
