Summary: This paper presents the authors’ technique for evaluation of possible abductor tears with MRI.

Abstract:
This paper presents the authors’ technique for evaluation of possible abductor tears with MRI. By utilizing T2 fat saturated coronal and axial slices of the hip and T1 coronal images of the pelvis the author demostrates how to visualize all tears of the abductor tendons and signs of chronic abductor deficiency. After diagnosis has been made signs that may help the surgeon determine if open or arthroscopic surgery would be best utilized are reviewed. Finally the author reviews indications for a gluteus medius repair with concomitant gluteus maximus reconstruction. The technique described is an algorithmic approach to evaluating the abductor tendons with MRI that will allow providers to accurately diagnose and determine the best method for surgical treatment of a patient with an abductor tear. The advantages of this technique are that by systematically utilizing this method the chance of a missed abductor injury are very slight. The authors also describe the MRI signs that may preclude an arthroscopic approach. If treating surgeons are able to decisively know whether an open or an arthroscopic approach are best suited for an abductor tear, this saves them from having to change from an arthroscopic to open approach mid-case, which can be time intensive.
