Weight-Bearing Hip MRI
Weight-Bearing Hip MRI applies body weight to the hip joints and to the supporting ligaments and acetabular labrum. The body weight compresses the hyaline cartilage of the hip joint and flattens and elongates the acetabular labrum along the lateral margin of the hip joint. Femoro-acetabular impingement occurs when the lateral margin of the acetabulum impinges against lateral margin of the head/neck junction of the proximal femur and produces hip pain during weight bearing and abduction of the hip.
• Body weight compresses cartilage and Labrum
• Evaluate stability of labral tears
• Diagnosis Femoro-Acetabular Impingement
• Stress loading of osteochondral lesions or subchondral collapse with avascular necrosis.
• Evaluation of internal femoro-acetabular impingement in the position of pain with weight-bearing.
• Stress testing of acetabular labral tears and diagnosis of labral instability.
• Evaluation of sports hernias and adductor mechanism injuries.
G2WB-MRI shows its greatest advantage over conventional high field strength MRI in the evaluation of Imaging following total hip arthroplasty or instrumentation. Low field strength MRI units produce very little metal artifact and metallic implants or THR can be evaluated during physiologic weight-bearing without the need for special Metal Artifact Reduction Sequence (MARS Protocol).
