Due to anatomical consideration, implant insertion is not risk free, and requires a steep learning curve. A robotic system has been successfully used in pedicle screws insertion and can be also used for iliosacral screws. The aim of the study was to demonstrate the use of the robot in the treatment of unstable sacral fractures.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Design:<\/jats:title>\n            <jats:p>Retrospective case series.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Setting:<\/jats:title>\n            <jats:p>An academic level I trauma center.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Patients:<\/jats:title>\n            <jats:p>Fourteen patients with sacral fractures were eligible for robotic assisted treatment.
