However, it remains unclear whether tissue damage is primarily caused by acetabular cartilage tears or inverted acetabular labrum
Matsumoto, "Inversion of the acetabular labrum
triggers rapidly destructive osteoarthritis of the hip: representative case report and proposed etiology," The Journal of Arthroplasty, vol.
The influence of the acetabular labrum
on hip joint cartilage consolidation: a poro-elastic finite element model.
Unlike SLAP tears in the shoulder, tears of the acetabular labrum
are more commonly seen as contrast tracking between the fibrocartilaginous labrum and the acetabular rim (Figure 16), rather than tracking into the substance of the labrum itself.
1,6) As the acetabular labrum
and articular cartilage degenerate, pain frequency increases.
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.
However, dislocation can lead to osteoarthritis due to the mechanical overload, while impingement causes injury to the acetabular labrum
and adjacent cartilage.
1 Anchors biowchlanialne made of osteokonduktywnego TCP and PLGA method to repair damaged mikrodyspersii acetabular labrum
of the shoulder joint.
As the hip joint becomes less stable, the acetabular labrum
initially hypertrophies in an attempt to maintain the femoral head within the acetabulum.
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
Pain in the hip region in dancers can be related to a variety of conditions, including injury to the acetabular labrum
and femoral cartilage as well as the tendons and bursae surrounding the hip.
