BACKGROUND The impact of a recurrent defect on the outcome after rotator cuff repair has been controversial. The purpose of this study was to evaluate the functional and anatomic results after arthroscopic repair of large and massive rotator cuff tears with use of ultrasound as an imaging modality to determine the postoperative integrity of the repair.

BACKGROUND Double-row arthroscopic rotator cuff repairs were developed to improve initial biomechanical strength of repairs to improve healing rates. Despite biomechanical improvements, failure of healing remains a clinical problem. PURPOSE To evaluate the anatomical results after double-row arthroscopic rotator cuff repair with ultrasound to determine(More)
The purpose of this study was to examine longitudinally the natural history of asymptomatic rotator cuff tears over a 5-year period and to assess the risk for development of symptoms and tear progression. Since 1985 through the present, bilateral sonograms were done on all patients. A review of consecutive sonograms done from 1989 to 1994 revealed 58(More)
BACKGROUND The purpose of this prospective study was to report the long-term risks of rotator cuff tear enlargement and symptom progression associated with degenerative asymptomatic tears. METHODS Subjects with an asymptomatic rotator cuff tear in one shoulder and pain due to rotator cuff disease in the contralateral shoulder enrolled as part of a(More)
BACKGROUND Very little comparative information is available regarding the demographic and morphological characteristics of asymptomatic and symptomatic rotator cuff tears. This information is important to provide insight into the natural history of rotator cuff disease and to identify which factors may be important in the development of pain. The purpose of(More)
BACKGROUND Partial-thickness rotator cuff tears are a common cause of shoulder pain, yet the appropriate surgical treatment is controversial. In particular, very little information is available regarding rotator cuff integrity after operative repair. The purpose of this study was to evaluate the functional outcome and anatomic healing rate after(More)
PURPOSE To determine and compare the diagnostic performance of computed tomography (CT), magnetic resonance (MR) imaging, ultrasonography (US), and positron emission tomography (PET) in the detection of hepatocellular carcinoma (HCC) or cholangiocarcinoma in liver transplant candidates and to determine interobserver variability between the readers.

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)
Ultrasound is the most commonly used imaging technique for the evaluation of thyroid nodules. Sonographic findings are often not specific, and definitive diagnosis is usually made through fine-needle aspiration biopsy or even surgery. In reviewing the literature, terms used to describe nodules are often poorly defined and inconsistently applied. Several(More)
We studied 25 patients with gangrenous cholecystitis and observed a new sonographic finding--striated thickening of the gallbladder wall--and three patterns of pericholecystic fluid collections. Heterogeneous thickening of the gallbladder wall was characterized by either multiple striations (alternating hypoechoic and hyperechoic layers) or irregular(More)
