Imaging of the acetabular labrum: a review

Introduction The acetabular labrum is a critical structure within the hip joint. Abnormality of the acetabular labrum is a significant cause of pain, and it plays an integral role in the development of osteoarthritis. This article reviews the normal anatomy and anatomical variants of the acetabular labrum and describes the technique for performing magnetic resonance arthrography. This article a...

Role of the acetabular labrum in load support across the hip joint.

The relatively high incidence of labral tears among patients presenting with hip pain suggests that the acetabular labrum is often subjected to injurious loading in vivo. However, it is unclear whether the labrum participates in load transfer across the joint during activities of daily living. This study examined the role of the acetabular labrum in load transfer for hips with normal acetabular...

Discrete mineralisation of the acetabular labrum: a novel marker of femoroacetabular impingement?

Femoroacetabular impingement (FAI) is increasingly thought to play a role in the development of hip osteoarthritis, but is difficult to define clinically and on imaging. This study investigates mineralisations of the acetabular labrum (MALs), which are small, discrete foci of dense radio-opacity within the region of the acetabular labrum. The study aims to characterise MALs and test the hypothe...

Acetabular labrum blood flow in developmental dysplasia of the hip: an intraoperative in vivo study using laser Doppler flowmetry

BACKGROUND The vascular supply to the acetabular labrum is important in the treatment of labral lesions. However, in vivo blood flow measurements in the acetabular labrum have not been described in the literature. The purpose of this study was to examine this blood flow in vivo using laser Doppler flowmetry (LDF) in patients with acetabular dysplasia. METHODS Periacetabular osteotomy combined...
