title: Current status of navigated cup replacement in dysplastic cases.
abstract: From the authors' experiences, several challenges exist in creating accurate cup positioning in patients with dysplastic hip due to anatomic abnormalities. B. Braun Aesculap (Tuttlingen, Germany) developed an advanced OrthoPilot software module for dysplastic cup positioning that has several advantages over the normal cup software as a solution to cup inaccuracies. The following study is a preliminary report on the new software version, which provides more specific functionality than the previous software system, a precondition or successful dysplastic cup navigation. This new functionality increase usefulness of navigation and the safety of the procedure.
