Pain felt to the rear of the ankle is the result of compression of the soft tissue or bone when 'plantar flexion' occurs, where the foot and ankle are angled away from the body. 57, No. FOIA Indirect MR arthrography of the shoulder: use of abduction and external rotation to detect full- and partial-thickness tears of the supraspinatus tendon, MR arthrographic depiction of tears of the rotator cuff: benefit of abduction and external rotation of the arm, Horizontal component of partial-thickness tears of rotator cuff: imaging characteristics and comparison of ABER view with oblique coronal view at MR arthrography initial results, Imaging findings in the dominant shoulder of throwing athletes: comparison of radiography, arthrography, CT arthrography, and MR arthrography with arthroscopic correlation, Magnetic resonance imaging evaluation of the rotator cuff tendons in the asymptomatic shoulder, Magnetic resonance imaging of the asymptomatic shoulder of overhead athletes: a 5-year follow-up study, The peel-back mechanism: its role in producing and extending posterior type II SLAP lesions and its effect on SLAP repair rehabilitation, Humeral torsion in the throwing arm of handball players, A comparison of glenoid morphology and glenohumeral range of motion between professional baseball pitchers with and without a history of SLAP repair, An analysis of 140 injuries to the superior glenoid labrum, SLAP lesions: a retrospective multicenter study, The Management of Superior Labrum Anterior-Posterior Tears in the Throwers Shoulder, Pathomechanics and Magnetic Resonance Imaging of the Throwers Shoulder, Diagnosis of superior labral lesions: comparison of noncontrast MRI with indirect MR arthrography in unexercised shoulders, Sensitivity and specificity of noncontrast magnetic resonance imaging reports in the diagnosis of type-II superior labral anterior-posterior lesions in the community setting, SLAP tears: diagnosis using 3-T shoulder MR arthrography with the 3D isotropic turbo spin-echo space sequence versus conventional 2D sequences, Labral injuries: accuracy of detection with unenhanced MR imaging of the shoulder, Noncontrast magnetic resonance imaging of superior labral lesions.
