PURPOSE The purpose of this study was to assess the functional results of arthroscopic repair of massive rotator cuff tears in patients who had stage 3 and 4 fatty degeneration of the rotator cuff musculature, according to the Goutallier scale. METHODS From January 1997 to December 2001, 22 patients with massive rotator cuff tears and Goutallier stage 3(More)
OBJECTIVE The typical bone bruise pattern involving the anterolateral femoral condyle and inferomedial patella after transient lateral dislocation of the patella is a well-described MRI finding. In our study, however, we sought to determine the incidence and location of lateral femoral condyle osteochondral injuries after transient lateral dislocation of(More)
Magnetic resonance imaging (MRI) has been shown in the literature to have high accuracy for the diagnosis of superior labrum anterior-to-posterior (SLAP) lesions. However, these studies have been performed at specialized institutions and have not been evaluated for community settings. Our hypothesis was that MRI diagnosis of SLAP lesions in the community(More)
OBJECTIVE The purpose of this study was to assess the diagnostic correlation between indirect MR arthrography, conventional MRI, and arthroscopy in acetabular labral and cartilage lesions of the hip. MATERIALS AND METHODS Fourteen patients who underwent conventional and indirect MR arthrography with arthroscopic correlation were studied over the course of(More)
Six patients with clinical histories and physical examination results consistent with iliotibial band friction syndrome (ITBFS) were examined with magnetic resonance (MR) imaging. Ill-defined decreased signal intensity on T1-weighted images and increased signal intensity on T2-weighted images was present deep to the iliotibial band, adjacent to the lateral(More)
PURPOSE To conduct a multi-center assessment of the use of a 0.2-T, extremity MR system (E-scan; General Electric Lunar Corp. and Esaote, Genoa, Italy) for identifying tears of the rotator cuff and glenoid labrum. MATERIALS AND METHODS A retrospective study was performed involving 160 patients (age range, 15-84 years old) from five facilities in the(More)
The in vivo and ex vivo microanatomic appearance of early disc degeneration were identified by magnetic resonance imaging and correlated with their respective histopathologic findings. Five cadaver spines (18 discs) and 25 patient studies (122 discs) all imaged at 1.5 Tesla were studied. Two signs of early degenerative disc disease were found: infolding and(More)
The sensitivity, specificity, and predictive value of magnetic resonance imaging in the diagnosis of lesions of the rotator cuff, glenohumeral capsule, and glenoid labrum were evaluated in ninety-one patients and fifteen asymptomatic volunteers. Magnetic resonance imaging demonstrated 100 per cent sensitivity and 95 per cent specificity in the diagnosis of(More)
To determine the diagnostic performance of magnetic resonance (MR) imaging in the evaluation of suspected rotator cuff tears, eight asymptomatic volunteers and 32 patients with rotator cuff tendonopathy who underwent surgery were examined with MR imaging. Twenty-four of these patients also underwent contrast arthrography. The ability of MR imaging to depict(More)
OBJECTIVE MR imaging of the shoulder was performed in an asymptomatic population to determine the prevalence of MR-evident peritendinous and bone abnormalities. Findings were correlated with subject age and rotator cuff abnormalities. SUBJECTS AND METHODS Dual-echo T2-weighted oblique coronal MR images of the shoulder were evaluated for 100 asymptomatic(More)
