The development of radiographic systems for the grading of osteoarthritis requires knowledge of the reproducibility of their individual component features. This paper reports the reproducibility, both within and between observers, for five commonly used radiographic features of osteoarthritis in the tibiofemoral and patellofemoral compartments of the knee joint. The results suggest that assessm...

OBJECTIVES To evaluate the influences of radiographic severity, quadriceps strength, knee pain, age, and gender on functional ability in patients with osteoarthritis of the knee. METHODS Equal numbers of knee pain positive and negative respondents to a survey of registrants aged more than 55 years at a general practice were invited to attend for knee radiographs and quadriceps femoris isometr...

Focal fibrocartilaginous dysplasia (FFCD) of the tibia is a rare tumor like lesion probably caused by a failure of differentiation in the pes anserinus area. The children usually present with unilateral tibia vara and conspicuous walking features. The radiographic appearance of FFCD is pathognomic. In most cases this benign condition undergoes spontaneous resolution. Curettage or corrective ost...

OBJECTIVE To describe a case of vitamin B(12) deficiency with classic and rare clinical features and novel radiographic features. DESIGN Case report. SETTING Johns Hopkins Hospital neurology service. PATIENT Middle-aged man with neuropathy, myelopathy,impaired cognition, and extrapyramidal signs. RESULTS The patient had neurologic and hematologic signs of vitamin B(12) deficiency, with ...

Objective: To familiarize the practitioner and specialist with the usual false features noticed in routine radiographs taken prior to surgery so that complicated treatment could be avoided. Materials and Methods: All the cases reported for lower third molar surgery underwent routine radiographic evaluation such as Intra-oral X-ray and OPG (Orthopantomograph) to assess the severity and the surgi...

BACKGROUND The features of pulmonary disease caused by rapidly growing mycobacteria (RGM) have not been sufficiently documented. OBJECTIVES To establish these features, we retrospectively evaluated 44 patients. METHODS We screened respiratory isolates at the National Toneyama Hospital (Osaka, Japan) between 2003 and 2007. Diagnosis was based on the latest guidelines of the American Thoracic...

BACKGROUND Radiographic sacroiliitis is the hallmark of ankylosing spondylitis (AS), and detection of acute sacroiliitis is pivotal for early diagnosis of AS. Although radiographic sacroiliitis is a distinguishing feature of AS, sacroiliitis can be seen in a variety of other disease entities. CASE PRESENTATION We present an interesting case of sacroiliitis in a patient with Paget disease; the...
