Abstract
Objective: To identify the radiographic correlate of the anatomic safe zone for tibial portal placement. Design: Cadaveric, anatomic, and radiographic study using twenty cadaveric knees. Kirschner wires were placed in the anatomic safe zone. Anteroposteri or and lateral radiographs were taken to evaluate the portal placement. Setting: Anatomy laboratory. Outcome measurements: Radiographic measurements of Kirschner wires placed i n the anatomic safe zone. Results: The safe zone for tibial nail placement as seen on radiographs is just medial to the lateral tibial spine on the anteroposterior radiograph a nd immediately adjacent and anterior to the articular surface as visualized on the lateral radiograph. There is some variance on the anteroposterior r adiograph but no variance on the lateral radiograph. Conclusions: The placement of tibial nails in the superior portion of the t ibia in the documented position generates the least risk to the intraarticu lar structures of the knee.
