Tibial Portal Placement: The Radiographic Correlate of the Anatomic Safe Zone

McConnell, Casey, et al.·J Orthop Trauma·2001·109 citations·Anatomic study

DOI·PubMed

Purpose

To identify the radiographic correlate of the anatomic safe zone for tibial portal placement.

Methods

Design:

Cadaveric, anatomic, and radiographic study using 20 cadaveric knees.
Kirschner wires were placed in the anatomic safe zone.
Anteroposterior and lateral radiographs were taken to evaluate the portal placement.

Setting: Anatomy laboratory.

Outcome Measures: Radiographic measurements of Kirschner wires placed in 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 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.

Conclusions

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.
