BACKGROUND Infections of bone and joint tissues following arthroplasty surgeries remain a major challenge in orthopaedic settings. Methicillin resistant Staphylococcus aureus (MRSA) is recognised as an established pathogen in such infections. Combination therapy using linezolid and bacteriophage impregnated in biopolymer was investigated in the present study as an alternative strategy to preven...

Artificial prostheses for joint replacement are indispensable in orthopedic surgery. Unfortunately, the implanted surface is attractive to not only host cells but also bacteria. To enable better osteointegration, a mechanically stable porous structure was created on titanium using laser treatment and metallic silver particles were embedded hydrophilic oxide layer top. The structuring resulted u...

background: effects of estrogen on bone metabolism and its protective role on prevention of osteoporosis are well   documented. however, the efficacy of estrogen treatment on bone healing is not well investigated. the drug can be delivered both systemically or locally to the bone with differences in concentrations and side effects. the aim of this study was to investigate the effect of local an...

Study Design. In vivo analysis in an ovine model.Objective. To evaluate the feasibility of radiopaque UHMWPE sublaminar wires in a growth-guidance spinal system by assessing stability, biocompatibility and growth potential.Summary of Background Data. Several growth-guidance systems have been developed for the treatment of early onset scoliosis (EOS). The use of gliding pedicle screws and metal ...

background: the advantages of coated orthodontic wires such as esthetic and their effectson reduced friction, corrosion and allergic reaction and the signifi cant consequences of plaque accumulation on oral health encouraged us to assess bacterial colonization on these wires. materials and methods: a total of 18 (9 upper and 9 lower) epoxy resin coated 16 × 22 nickeltitanium wires (spectra, gac...

Orthodontic tooth movement is a physiologic response to externally applied forces; the motive forces are primarily mechanical. The optimal application of orthodontic force enables maximum movement of teeth with minimal irreversible damage of the periodontal ligament (PDL), alveolar bone, and teeth. Since arch wires are the main force system in orthodontics, it is important in clinical practice ...

PURPOSE To assess the effectiveness of Brooks' posterior stabilisation and fusion for the unstable atlantoaxial joint due to congenital dysplastic dens and trauma. METHODS We retrospectively studied records of 54 patients (36 males and 18 females; age range, 3-58 years) who underwent Brooks' posterior stabilisation procedure between March 1975 and December 1999, at the Catholic University of ...

This case illustrates the importance of a thorough clinical history and the benefit of histopathologic examination. The history of contact allergy to jewelry provided an early clue, and the microscopic features confirmed the clinical impression of allergic stomatitis.
