In addition, the acetabular labrum
was found to absorb part of this load, which resulted in reduction of the cartilage pressure.
The labral plica is found at the inferomedial margin of the acetabular labrum
. The ligamentous and labral plicae are particularly problematic, since they can mimic tears of the ligamentum teres and acetabular labrum
Therefore, this study aimed to assess whether abnormal tissue embedded in the hip joint is avulsed acetabular cartilage, inverted acetabular labrum
, or other types of tissues such as aberrant ligamentum teres, we harvested the disk-like abnormal tissue from the hip joint during surgery and performed histological staining to investigate its property.
Arthroscopic debridement versus refixation of the acetabular labrum
associated with femoroacetabular impingement.
(17) With hip flexion and internal rotation in pincer FAI, the femoral neck abuts against the anterosuperior acetabular labrum
(which in this case acts as a buffer), compressing it into the articular cartilage and subchondral bone (see
The occurrences of tears in the athlete's acetabular labrum
have been reported in sports that place rotational demands on the hip (such as tennis, golf, and hockey) (Binningsley, 2003; Mason, 2001; McCarthy et al., 2003).
B, Axial magnetic resonance arthrogram demonstrating torn acetabular labrum
(white arrow) with anterior subluxation of the humeral head (black arrow).
Magnetic resonance (MR) arthrography of the hip is a well-proven and useful technique for the diagnosis of intra-articular lesions, especially of the acetabular labrum
. [sup],, Information about the safety of hip arthrography and about the patients' tolerance of the procedure has become more important, with an increase in the number of intra-articular contrast injections that are performed.
As indicated earlier, interest in the acetabular labrum
has grown in the medical community, and this has produced substantial kinematic and biomechanical research.
in 1995 and was shown to better depict the acetabular labrum
than conventional MR imaging.
Hip pain in the young adult: diagnosis and treatment of disorders of the acetabular labrum
and acetabular dysplasia.
Although the inverted acetabular labrum
was proposed to be the trigger of SIF , we could not detect an inverted labrum on MRI in our case.
