Purpose: Management of anterior ring injuries is still a matter of discussion, and there are only few studies reporting anterior external fixator as definitive treatment for unstable pelvic injuries. This study aimed to describe the clinical and radiological outcomes of a consecutive series of mechanically unstable pelvic injuries that were treated with definitive anterior supra-acetabular external fixator for the anterior ring, and to identify risk factors for failure.
Methods: We included a consecutive series of patients with unstable pelvic ring fractures who underwent anterior supra-acetabular external fixation for definitive treatment, between January 2012 and January 2020.
Femoroacetabular impingement is the mechanical contact between the femur and the pelvis, frequently between the femur neck and the acetabular rim, whether due to a deformity of the former (cam type) or the latter (pincer type). However, there may be extraarticular causes of impingement. Together with the increased diagnosis of impingement, arthroscopic treatment is increasingly frequent and has become the standard treatment.
