BACKGROUND Normative data are essential to the evaluation of shoulder function. The purposes of this study were to establish a normative database of isometric shoulder strength measured in asymptomatic individuals verified to have intact rotator cuffs and to determine the effect of asymptomatic rotator cuff tears on shoulder strength. METHODS Two hundred(More)
The demographic and morphological features of rotator cuff disease: A comparison of asymptomatic and symptomatic shoulders." The Background: Very little comparative information is available regarding the demographic and morphological character
AIM Our aim was to investigate muscle architecture and size of the rectus femoris (RF) and vastus lateralis (VL) in children and adolescents with cerebral palsy (CP) compared with age-matched typically developing participants. METHOD Muscle architecture and size were measured with ultrasound imaging in 18 participants with spastic CP (9 females, 9 males;(More)
BACKGROUND It has been theorized that degenerative rotator cuff tears most commonly involve the supraspinatus tendon, initiating at the anterior portion of the supraspinatus insertion and propagating posteriorly. The purposes of this study were to determine the most common location of degenerative rotator cuff tears and to examine tear location patterns(More)
BACKGROUND Fatty degeneration of the rotator cuff muscles may have detrimental effects on both anatomical and functional outcomes following shoulder surgery. The purpose of this study was to investigate the relationship between tear geometry and muscle fatty degeneration in shoulders with a deficient rotator cuff. METHODS Ultrasonograms of both shoulders(More)
OBJECTIVE The purpose of this study was to analyze the sonographic appearance of a large series of pathologically proven ganglia. MATERIALS AND METHODS A computer search of sonography and pathology reports for hand and wrist ganglia was performed. All sonography reports and images were reviewed for ganglion size, location, presence of a neck,(More)
INTRODUCTION Little information exists regarding the long-term outcome after structural failure of rotator cuff repair. We previously reported clinical improvement, despite a 94% rate of failure of healing, at two years of follow-up in a cohort of eighteen patients who had undergone arthroscopic repair of massive rotator cuff tears. The purpose of the(More)
OBJECTIVE The purpose of this study was to determine the reliability of sonographic visualization of the normal extrapelvic vas deferens and to analyze its appearance and dimensions. METHODS Scans of the scrotum and spermatic cords were obtained in 25 fertile volunteers. Identification of the vas deferens was attempted bilaterally in the scrotal,(More)
BACKGROUND Diagnostic evaluation of rotator cuff muscle quality is important to determine indications for potential operative repair. Ultrasonography has developed into an accepted and useful tool for evaluating rotator cuff tendon tears; however, its use for evaluating rotator muscle quality has not been well established. The purpose of this study was to(More)
