PURPOSE Diagnosis of partial rotator cuff tears and tendonopathy using conventional MRI has proven variable. Quantitative T2 mapping may have application for assessing rotator cuff health. In order to evaluate the usefulness of T2 mapping for the rotator cuff, methods must be refined for mapping the supraspinatus tendon, and normative T2 values must first(More)
BACKGROUND The prevalence of abnormal magnetic resonance imaging (MRI) findings in an asymptomatic population has yet to be determined. PURPOSE The purpose of this study was to assess a cohort of asymptomatic people to determine the prevalence of hip lesions. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Forty-five volunteers with(More)
BACKGROUND Microfracture of full-thickness articular defects has been shown to significantly enhance the amount of repair tissue. However, there is a suggestion that leaving calcified cartilage inhibits this repair response. HYPOTHESIS Removal of the calcified cartilage with retention of subchondral bone enhances the amount of attachment of the repair(More)
Recent studies and consensus statements have expressed the need to involve palliative care services in the care of children with progressive neuromuscular diseases (PMD), yet there have been no reviews of the utilization of palliative care services by children who died on a palliative care program. We conducted a retrospective chart review of all children(More)
The purpose of this study was to investigate the relationship between femoral neck version and pre- and intraoperative findings in hips with femoroacetabular impingement (FAI). The authors retrospectively reviewed prospectively collected data on 188 patients (204 hips) who underwent hip arthroscopy for FAI and labral pathology. Femoral version was measured(More)
BACKGROUND It has been reported that relative to other sports participants, ice hockey players suffer from cam-type femoroacetabular impingement (FAI) in higher numbers. α angles have been reported to increase with the likelihood of symptomatic FAI. It is unclear how prevalent increased α angles, commonly associated with cam FAI, are in asymptomatic young(More)
BACKGROUND To date, stress injury of the proximal ulna has been infrequently reported as a cause of elbow pain in the throwing athlete. PURPOSE We describe a syndrome of osseous stress injury of the proximal ulna in the professional throwing athlete. STUDY DESIGN Retrospective review. METHODS We evaluated the clinical, radiographic, and magnetic(More)
BACKGROUND The tibial tubercle-trochlear groove (TTTG) distance is used to quantify the degree of lateralization of the patellar tendon insertion on the tibial tubercle relative to the deepest part of the trochlear groove. Disagreement exists as to whether the TTTG distance measured on computed tomography (CT) and magnetic resonance imaging (MRI) can be(More)
Quantitative MRI T2 mapping is a non-invasive imaging technique sensitive to biochemical changes, but no studies have evaluated T2 mapping in pathologic rotator cuff tendons. It was sought to evaluate the efficacy of T2 mapping in detecting differences in the supraspinatus tendon (SST) among patients with tendinosis, partial tears and minimally retracted(More)
We attempted to assess the accuracy of magnetic resonance imaging (MRI) in determining the size of recurrent cuff tears in correlation with size measured at surgery. Thirty-seven shoulders in 33 patients who had reoperation for a presumed failed rotator cuff repair were retrospectively evaluated. All patients had preoperative MRI, the results of which were(More)
