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.
Structure and vascularization of the acetabular labrum
with regard to the pathogenesis and healing of labral lesions.
FAI results in maceration of the acetabular labrum
between the femoral neck and osseous rim of the superior acetabulum.
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
Not only could injury occur to the acetabular labrum
, but the repetitive rotational velocities may also be contributing to joint ROM adaptations.
Magnetic resonance arthrography of the acetabular labrum
Corresponding coronal MR image shows filling defect to be a degenerated, hypertrophied acetabular labrum
(arrows), a common consequence of dysplastic hip morphology.
This contact causes abnormal stress on the acetabular labrum
and articular cartilage.
Longitudinal ultrasound images demonstrate tiny calcifications (arrowhead) within the anterior acetabular labrum
(A= acetabulum, F = femoral head).
Hickman JM, Peters CL: Hip pain in the young adult: Diagnosis and treatment of disorders of the acetabular labrum
and acetabular dysplasia.
This review examines the structure and function of the acetabular labrum
, investigates the epidemiology and etiology of labral tears as well as the current conservative and surgical treatment.
This case report includes a description of the relevant examination and treatment procedures as well as a discussion of hip instability and the acetabular labrum
