in this paper attempts have been done to create a mortar with relatively high uniaxial compressive strength (ucs), easy casting, high flexibility, instant hardening, low cost and easy availability. the main use of this material is to physically model the mechanical behavior of jointed rock-like blocks. the effect of four parameters such as joint roughness coefficient (jrc), bridge length (l), b...

BACKGROUND AND PURPOSE In some patients, for unknown reasons pain persists after joint replacement, especially in the knee. We determined the prevalence of persistent pain following primary hip or knee replacement and its association with disorders of glucose metabolism, metabolic syndrome (MetS), and obesity. PATIENTS AND METHODS The incidence of pain in the operated joint was surveyed 1-2 y...

Background: Persistent wound leakage after joint arthroplasty is a scantily investigated topic, despite the claimed relation with a higher risk of periprosthetic joint infection. This results in a lack of evidence-based clinical guidelines for the diagnosis and treatment of persistent wound leakage after joint arthroplasty. Without such guideline, clinical practice in orthopaedic hospitals vari...

Background: The ultimate goal of the treatment of infectious knee arthritis is to protect the articular cartilage fromadverse effects of infection. Treatment, however, is not always hundred percent successful and has a 12% failurerate. Persistent infection is more likely to happen in elderly patients and those with underlying joint diseases,particularly osteoarthritis. Eradica...

PURPOSE The present study was undertaken to elucidate the factors responsible for the failure of arthrocentesis to cure persistent joint pain in patients with nonreducing articular disc displacement in the temporomandibular joint (TMJ). PATIENTS AND METHODS Thirty-six patients with internal derangement of the TMJ were selected. Magnetic resonance imaging was used to examine the configuration ...

Despite the lack of validation, synovial aspiration remains a common practice during 2-stage septic revision total knee arthroplasty (TKA). The goal of this study was to investigate the diagnostic validity of synovial polymethylmethacrylate (PMMA) spacer aspiration of temporary knee arthrodesis to detect persistent periprosthetic joint infection before TKA reimplantation. This retrospective coh...

BACKGROUND Persistent complaints are very common after a lateral ankle sprain. AIM To investigate possible associations between structural abnormalities on radiography and MRI, and persistent complaints after a lateral ankle sprain. DESIGN AND SETTING Observational case control study on primary care patients in general practice. METHOD Patients were selected who had visited their GP with ...
