MRI of failed total hip replacement caused by abductor muscle avulsion.
OBJECTIVE
Our purpose is to describe the use of MRI and associated metal artifact reduction techniques to detect abductor muscle avulsion from the greater trochanter, a complication unusual to the anterolateral approach for total hip replacement.


CONCLUSIONS
MRI facilitates the detection of abductor muscle avulsion in patients who have undergone the anterolateral approach during total hip replacement. MRI is considered a valuable diagnostic tool when this condition is suspected.
