This is a cross-sectional study of bone densitometry in greater than 700 normal healthy white women ranging in age from 18 to 98 years. A modified procedure for single-photon bone density analysis of the distal radius is described and compared with dual-photon densitometric measurements of the second through fourth lumbar vertebrae. The distal radial site(More)
Cysts of the mesothelial investment of the round ligament are rare and occur in women in their late third or fourth decades. They are relatively painless, mobile, may be perceived to be reducible, and should be included in the differential diagnosis of groin masses in women. Differentiation of these cysts from a small indirect inguinal hernia, with which(More)
This study reports a new technique for the measurement of bone mineral content (BMC) in live rats. A single photon absorptiometric instrument has been adapted for rapid, reproducible measurement of BMC. Four bone sites were selected for use, based on ease of positioning and reproducibility of measurement; these were as follows: proximal femur, midfemur,(More)
Arthroscopy and arthroscopic surgery have gained tremendous popularity within the past several years with both physicians and the general public. Arthroscopic surgery is a dramatic aid in reducing soft tissue injury, rehabilitation time, and the costs associated with surgery when applied to the knee or other large joints of the body. Although this technique(More)
It is not uncommon to observe bone cement in the pelvis on radiographs after total hip replacement, a finding which is generally considered to be benign. This paper reviews some catastrophic late complications from intrapelvic methylmethacrylate. We also describe a case of progressive, unbearable dyspareunia beginning three years after total hip(More)
The femoral heads of 12 dogs with naturally occurring Legg-Calvé-Perthes disease were studied by light and electron microscopic techniques. In the early stages of the disease, the bony capital femoral epiphysis was necrotic, but the articular cartilage and growth plate cartilage were not affected. By the early stages of repair, the femoral head had(More)
This report describes the use of a new micro-thin resistive-based sensor to measure dynamic vertical loading of normal and osteoarthritic (OA) human knee cartilage repetitively under conditions of simulated knee joint loading. Articular cartilage discs were cultured in 3 DMEM +/- IL-1, lipopolysacharide (LPS) and trypsin over 7 days. Loading force, force(More)
Evidence is presented for the synthesis of Interleukin-1 (IL-1) by joint synovial tissue and chondrocytes. Purified preparations of mouse and human recombinant forms of this factor stimulate the synthesis of a secretory protease by cartilage. The IL-1 stimulated chondrocyte protease is capable of converting latent collagenase to its active form. Other(More)
Septic bursitis of the foot is a disorder infrequently reported in the medical literature. This infrequent reporting may represent a true low incidence of occurrence or may be a reflection of failure to recognize and diagnose this condition. This paper retrospectively reviews the presentation, clinical course, and outcome of patients presenting with septic(More)
