PURPOSE To evaluate the sonographic findings of plantar fasciitis. MATERIALS AND METHODS Both feet of 15 patients who had a clinical diagnosis of plantar fasciitis were evaluated with ultrasound (US) by using a 7.0-MHz linear-array transducer. Heel pain was unilateral in 11 patients and bilateral in four. Sagittal sonograms were obtained, and the(More)
Endogenous Cushing's syndrome can result from excess adrenocorticotropic hormone (ACTH; corticotropin) production by a pituitary adenoma (Cushing's disease) or by ectopic tumors secreting ACTH or corticotro- pin-releasing hormone (CRH). ACTH-independent Cushing's syndrome is caused by adrenocortical tumors or hyperplasias. Initial diagnosis is performed(More)
Twenty-two adult patients, aged 18 and over, with Ewing's sarcoma of bone, were evaluated clinically and radiographically. They had clinical findings similar to younger patients with Ewing's sarcoma, except that they presented with fewer systemic symptoms. The radiographic characteristics included a preponderance of flat bone involvement (54%) over long(More)
Ultrasound is a low-cost, nonionizing, readily available diagnostic technique for the evaluation of tendons, muscles, soft tissue masses, cysts, and other fluid collections. Ultrasound is also a valuable tool for guiding a variety of musculoskeletal interventions. Procedures that can be performed under ultrasound guidance include aspiration of fluid for(More)
To describe radiographic features of gout that may mimic infection. We report five patients with acute bacterial gout who presented with clinical as well as radiological findings mimicking acute bacterial septic arthritis or osteomyelitis. Three patients had delay in the appropriate treatment with the final diagnosis being established after needle(More)
We review the technique of double-contrast arthrotomography (DCAT) including reference to a new, superficial and bevel-oriented puncture and the use of a special density compensation filter. We have found it possible to demonstrate the varieties, size and exact location of rotator cuff tears in the coronal and sagittal planes. Adaptation of the method to(More)
Double-contrast arthrotomography of the shoulder appears extremely valuable; we have verified its accuracy in measurements of complete rotator cuff tears. The first 31 patients so investigated and explored surgically have been retrospectively evaluated. Accurate measurements were found in 85% of the coronal diameters and in 69% of the sagittal ones.
A 54-year-old man, a restaurant waiter, was seen at the orthopedic clinic for a history of pain in his left thumb resulting from a relatively minor trauma sustained at work in September 1990. Past medical history was noncontributory. A radiograph of the left thumb (Fig. 1) was normal. Physical examination revealed mild tenderness around the interphalangeal(More)
