Bucket-Handle Tear of Acetabular Labrum Accompanying Posterior Dislocation of the Hip

Acetabular Labral and Chondral Pathology

“…Labral pathology as a source of hip pain has only been widely recognised relatively recently. However, the first to mention a labral tear after an irreducible posterior hip dislocation was Peterson in 1957 [17], followed by Dameron in 1959 [18]. Altemberg [19] was the first to report two cases of a non-traumatic labral tear, which were treated by open resection of the torn fragments, and Suzuki et al [20] were the first to publish their experience of observing labral tears arthroscopically in five patients.…”

“…Trauma, in the form of an obvious acute major hip injury was primarily thought to be the main reason for labral tears [17,18]. It is now known that repetitive minor trauma, especially in athletes, may have the same effect.…”

Hip arthroscopy in athletes

“…39 An entrapped labrum has been reported as a cause of an irreducible posterior dislocation and a Bankart-type detachment of the posterior labrum has been identified as the cause of recurrent posterior instability. 40,41 These circumstances have only rarely been reported but may be recognized with increasing frequency as our understanding and intervention of hip injuries evolves.…”

Hip Biomechanics: Importance to Functional Imaging

“…Injury to labra may result from acute and chronic trauma, 48,51,[113][114][115][116][117][118][119][120][121][122][123][124] repetitive microtrauma and aging, 43,125 or hip dysplasia. 47,48,50,126,127 Reduced femoral neck anteversion or femoral head-neck offset lower clearance of the neck in flexion, especially when internal rotation is present, and may lead to impingement of the neck against the acetabular rim and labral injury.…”
