Partridge bands have been developed and marketed on the assumption that their ribbed under-surface would ensure less interference with periosteal and cortical blood flow than other cerclage systems. Three cases are reported of serious clinical complications from loss of cortical bone under the band, and interference with the external bridging callus response.

IL-17 is a T cell-derived proinflammatory cytokine in experimental arthritis and is a stimulator of osteoclastogenesis in vitro. In this study, we report the effects of IL-17 overexpression (AdIL-17) in the knee joint of type II collagen-immunized mice on bone erosion and synovial receptor activator of NF-kappa B ligand (RANKL)/receptor activator of NF-kappa B/osteoprotegerin (OPG) expression. ...

Bone destruction is the most difficult target in the treatment of rheumatoid arthritis (RA). Here, we report that local overexpression of IL-4, introduced by a recombinant human type 5 adenovirus vector (Ad5E1mIL-4) prevents joint damage and bone erosion in the knees of mice with collagen arthritis (CIA). No difference was noted in the course of CIA in the injected knee joints between Ad5E1mIL-...

PURPOSE We assessed whether MRI measures of synovitis, osteitis and bone erosion were associated with patient-reported outcomes (PROs) in a longitudinal clinical trial setting among patients with rheumatoid arthritis (RA). METHODS This longitudinal cohort of 291 patients with RA was derived from the MRI substudy of the GO-BEFORE randomised controlled trial of golimumab among methotrexate-naïv...

PURPOSE To review the CT and MR characteristics of temporal bone malignancy, and to evaluate the relationship between malignancies of the temporal bone and parotid gland. METHODS A group of 15 surgical patients with diagnosis of temporal bone malignancy were retrospectively reviewed. These included 11 cases of primary temporal bone malignancy and four cases of secondary carcinoma of the tempo...

OBJECTIVE To monitor size and shape changes of bone erosions and changes in BMD in the vicinity of the erosion and in the periarticular trabecular compartment of patients with RA using high-resolution peripheral quantitative CT (HR-pQCT) imaging and to compare an automated three-dimensional (3D) image processing technique with manual measurements of erosion width and depth. METHODS The shape ...

OBJECTIVES The authors recently demonstrated that extensive bone erosion correlated with a worse prognosis of the squamous cell carcinoma (SCC) of the temporal bone. The present objective was to investigate the expressions and the roles of epithelial-mesenchymal transition (EMT) in SCC of the temporal bone. STUDY DESIGN Retrospective patient file review and immunohistochemical study of tissue...

OBJECTIVES The aim of this study is to investigate the relationship between the thickness of the roof of the glenoid fossa in the temporomandibular joint (TMJ) and the existence and types of condylar bone change. MATERIALS AND METHODS Helical CT was used to measure the thickness of the roof of the glenoid fossa at its thinnest part in 37 orthodontic patients with temporomandibular disorders. ...

OBJECTIVE Osteopontin (OPN) is a secreted glycoprotein involved in a range of physiologic processes, including inflammation, immunity mediated by Th1 cells, and bone remodeling. It is expressed in the joints of rheumatoid arthritis patients and has been the subject of conflicting reports concerning its role in arthritis induced by antibodies against type II collagen. This study assessed the rol...
