Fractures through the disc or juxta-end plate region of the vertebra as well as the posterior elements have been observed in the thoracic and lumbar spine in ankylosing spondylitis. These are usually associated with increasing pain, usually do not produce neurologic deficit, and may require orthopedic fixation to heal. Irregularity and sclerosis at the(More)
Mycoplasma arthritidis and Mycoplasma pulmonis induced chronic arthritis in rabbits on intraarticular injection, characterized by joint swelling and histologic evidence of chronic active inflammation persisting at least one year. Cartilage and bone destruction was a prominent late feature of M arthritidis but not M pulmonis disease. Despite the progressive(More)
Twenty patients with 21 total joint replacements including 17 hips and 4 knees were studied by plain film radiography, radionuclide imaging, and subtraction arthrography to evaluate these procedures for assessing prosthetic complications. Surgery was performed in 14 patients and confirmed loosening of 8 femoral and 7 acetabular hip prosthesis components and(More)
Two cases of a craniotubular hyperostosis are presented. The radiographic features closely resemble Van Buchem disease (hyperostosis corticalis generalisata; endosteal hyperostosis, recessive type), including symmetrical and bilateral diaphyseal cortical thickening of the long and short tubular bones as well as sclerosis and thickening of the calvaria,(More)
Although synovial cysts are most commonly associated with rheumatoid arthritis and osteoarthritis, they may occur in many other conditions. The clinical manifestations of these cysts are numerous and may result from pressure, dissection or acute rupture. Vascular phenomena occur when popliteal cysts compress vessels, and result in venous stasis with(More)
Eighteen cases of long-standing rheumatoid arthritis and superimposed pyarthrosis were reviewed to determine the most distinguishing radiographic features. Soft-tissue changes allowed earlier diagnosis in the knee and ankle joints and consisted of large asymmetrical joint effusion and fat-pad edema. Bony articular changes were more helpful than soft-tissue(More)
Chondral fractures are a distinct clinical entity and should be distinguished from the more frequently recognized osteochondral fracture. They occur most often in the medial femoral condyle of young adults following a rotational injury or direct blow to the knee. Clinically, the chondral fracture mimics a torn meniscus and may or may not be associated with(More)
As total knee replacement becomes more successful due to advances in surgery and bioengineering, a greater number of patients will be offered this procedure as a viable alternative to arthrodesis. Radiologic consultation will be sought for evaluation of proper alignment as well as postoperative complications such as loosening, instability, dislocation,(More)
Previous reports have stressed the value of hip arthrography primarily in determining the presence of loosening of the total hip prosthesis. Although loosening is a common complication and frequently associated with infection, other complications producing a painful hip prosthesis exist and are demonstrable by arthrography. Since the etiologies of these are(More)
