The purpose of this comprehensive review of the literature is to collect as many cases of inferior dislocation as possible to determine better therapeutic strategies, outcome after reduction, complications, and prognostic factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>In April 2020, a literature search was performed in Pubmed, Medline, Scopus, Cochrane, and Embase databases.

This review of the literature has allowed us to differentiate 3 radiographic subtypes of inferior dislocations, which correspond to 3 different anatomical positions of the femoral head: \u201cobturator\u201d dislocation, \u201cproximal anterior-inferior\u201d dislocation, and \u201cdistal anterior-inferior\u201d dislocation. Our subtype classification yielded 39 obturator subtype inferior dislocations (32.8%), 66 proximal anteroinferior subtypes (55.4%), and 14 distal anteroinferior (11.8%). The obturator subtype is at risk of reduction failure and femoral neck fracture during the reduction manoeuver.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Our study identified 3 subtypes with different prognosis, with obturator and distal anteroinferior dislocations having a poorer prognosis because of their pre- and post-reduction complications. We were unable to determine the correct manoeuver to reduce inferior dislocations without taking the risk of femoral neck fracture, but each of these subtypes may require a different manoeuver.<\/jats:p>\n
