Mapping of Posterior Talar Dome Access Through Posteromedial Versus Posterolateral Approaches

Objective:

To evaluate the accessible area of the talar dome through 2 standard posterior approaches [posteromedial (PM) and posterolateral (PL)] with and without distraction.

Methods:

A standard PM or PL approach was performed with and without external fixator distraction on 12 through-knee cadaveric legs (6 matched pairs). The accessible area of the talar dome was outlined and imaged in a microcomputed tomography scanner to achieve 3D reconstructions of the accessible surface area. The study outcomes were accessible surface area of the talar dome in (1) total surface area and (2) sagittal plane distance of the talar dome at predetermined intervals.

Results:

The PM approach provided significantly more access to the talar dome than did the PL approach both with and without distraction (P
