Pre- and Post-Operative Analysis of Planar Radiographs in Total Hip Replacement
Computed-Tomography scans represent the gold standard for accuracy when preoperatively templating and postoperatively assessing the hip. However, planar radiographs are used as standard, sacrificing accuracy. In this work, a method is proposed to more accurately assess femoral offset and neck-shaft angle from two planar radiographs (frontal and lateral), allowing more reliable templating of a modular stem. A second method is proposed to accurately assess postoperative stem version from planar frontal radiographs.
