Abstract Background: Radiography is the most widely available imaging modality. Precise evaluations of wrist x-ray can help diagnosis and evaluate the prognosis of many wrist disorders. Methods: We measured length, angles and indices in 150 posteroanterior and lateral wrist x-rays to determine normal dimensions and variations according to age and sex. All x-rays were made with standar...

The launching of magnetohydrodynamic outflows from accretion disks is considered. We formulate a model for the local vertical structure of a thin disk threaded by a poloidal magnetic field of dipolar symmetry. The model consists of an optically thick disk matched to an isothermal atmosphere. The disk is supposed to be turbulent and possesses an effective viscosity and an effective magnetic diff...

The presence of an imposed external magnetic field may drastically influence the structure of thin accretion discs. The magnetic field energy is here assumed to be in balance with the thermal energy of the accretion flow. The vertical magnetic field, its toroidal component B tor at the disc surface (due to different rotation rates between disc and its magnetosphere), the turbulent magnetic Pran...

Using a volar approach to avoid the soft tissue problems associated with dorsal plating, we treated a consecutive series of 29 patients with 31 dorsally displaced, unstable distal radial fractures with a new fixed-angle internal fixation device. At a minimal follow-up time of 12 months the fractures had healed with highly satisfactory radiographic and functional results. The final volar tilt av...

BACKGROUND It is standard practice to closely monitor distal radial fractures treated nonoperatively to ensure that there is no fracture displacement. Patients are often asked to initially return weekly for radiographs. To our knowledge, nondisplaced distal radial fractures in adults have not been specifically evaluated to determine if this level of vigilance is required. If this subset of frac...

Background & Aims: Treatment of osteoporotic distal radius fracture with metaphyseal defect is often complicated by secondary displacement, because of posterior cortex comminution. The aim of this study was to investigate functional outcomes and advantages of injection of bone cement in stabilizing and maintaining this fracture reduction. Methods: This prospective study was performed on 20 ...

Background: Distal radius fractures are one of the most common fractures of skeletal system and because of the aging of population, its incidence is rising. The aim of the present research was to evaluate the close reduction and percutaneous pin fixation as a treatment option. Material and methods: 44 patients who were type 2 according to universal classification or type 2 or 3 according to Ol...

Distal radius fractures are one of the most common injuries and this incidence is likely to increase as the aging population increases. The type of operation and implant is a matter of discussion and randomized trials and meta analyses have failed to recommend the preferred implant. Internal fixation with volar locking plate and external fixation with supplementation with K wire have been succe...
