purpose: to determine the prevalence of intraocular injuries in patients with blow-out fracture and also to evaluate the etiologic mechanism of orbital blow-out fractures methods: this study is a consecutive case series analysis of 116 patients with orbital blow-out fractures. the patients were visited by an ophthalmologist within 24 hours of trauma. results: ninety-one men and twenty-five wome...

OBJECTIVES In the 18 month "alendronate or alfacalcidol in glucocorticoid-induced osteoporosis"-trial (STOP-trial) patients with rheumatic diseases who started glucocorticoids were randomised to anti-osteoporosis therapy with either daily alendronate (10 mg) or alfacalcidol (1 microg). In the present observational open follow-up study of the STOP-trial, we report the long-term effects of risk f...

PURPOSE To enhance the awareness of rare complications of pelvic fracture and describe the correct diagnosis and effective treatment. METHODS A total of 188 cases of pelvic fractures were retrospectively reviewed, and four patients who suffered from four types of rare pelvic fracture complications were described, namely ureteral obstruction caused by retroperitoneal hematoma-induced abdominal...

The technology of multiple hydraulic fracture stimulation in horizontal wells has trans‐ formed the business of oil and gas exploitation from extremely tight, unconventional hydro‐ carbon bearing rock formations. The fracture stimulation process typically involves placing multiple fractures stage-by-stage along the horizontal well using diverse well completion technologies. The effective design...

Background and purpose - Studies of fracture healing have mainly dealt with shaft fractures, both experimentally and clinically. In contrast, most patients have metaphyseal fractures. There is an increasing awareness that metaphyseal fractures heal partly through mechanisms specific to cancellous bone. Several new models for the study of cancellous bone healing have recently been presented. Thi...

As a result of negligible connected porosity—and thus, minimal matrix permeability—the fluid-transport characteristics crystalline rocks are strongly influenced by the fractures at all scales. Understanding flow behaviour fractured rock under extreme stress and temperature conditions is essential for safe effective deep geo-engineering applications, such as geothermal recovery, geological nucle...

Open reduction internal fixation (ORIF) metal plates provide exceptional support for unstable bone fractures; however, they often result in debilitating soft-tissue adhesions and their rigid shape cannot be easily customized by surgeons. In this work, a surgically feasible ORIF methodology, called AdhFix, is developed combining screws with polymer/hydroxyapatite composites, which are applied sh...

BACKGROUND Fall-induced injuries in persons aged 65 years and older are a major public health problem. Data regarding circumstances leading to specific injuries, such as traumatic brain injury (TBI) and hip fractures in older adults are scarce. OBJECTIVE To investigate the activity distributions leading to indoor and outdoor falls requiring an emergency department (ED) visit, and those result...

Summary While variations of seismic reflection amplitudes with incidence angle (AVA) and azimuth have been widely used to provide information on geometric characteristics fractures, this attribute has, as yet, not linked fracture interconnectivity, which tends govern the hydraulic property affected formation. This is due limitations forward models considered represent corresponding responses. B...
