Navigated femoral nailing using noninvasive registration of the contralateral intact femur to restore anteversion. Technique and clinical use.

摘要

The difficulty in assessing femoral rotation during intramedullary nailing is well-established. Navigation systems allow the surgeon to detect and set the version of the injured leg at the desired angle. We report the first cases of navigated femoral nailing using noninvasive registration of the contralateral uninjured leg to determine the patient's anatomy. This allows the desired femoral rotation, which is that of the healthy femur, to be statically locked to precisely match the contralateral limb.
