Ninety-two percent anterior and 8% posterior tears have been identified by Fitzgerald15; 62.2% anterior, 29.7% posterior, and 8.1% superior were recognized by Lage and coauthors.11 Conversely, Ikeda and coauthors17 found six posterior labral tears of the seven included in their report.
Differences in both morphology and location of the rupture reported by different authors11'15'17 are significant. This variation may be explained partially by the fact that most of the Fitzgerald15 cases were treated with open surgery, whereas Lage and coauthors11 always used an arthroscopic technique. The unusually high rate of posterosuperior tears recognized by Ikeda and coauthors17 has not found support in the litera-ture.11,15 Tears of the acetabular labrum seem most commonly to be located anteriorly.
