BACKGROUND There have been reports both supporting and refuting an inverse relationship between hip fracture and hip osteoarthritis (OA). We explore this relationship using a case-control study design. METHODS Exclusion criteria were previous hip fracture (same side or contralateral side), age younger than 60 years, foreign nationality, pathological fracture, rheumatoid arthritis and cases we...

50% of postmenopausal women and 10%–20% of older men, causing substantial morbidity, mortality and cost to society. Prevention of osteoporotic fractures is an important component of health care that relies on the accurate prediction of who is likely to sustain a fracture. Although predicting events is not easy, models that predict fracture have been developed and then validated in external popu...

Identification of chemical reaction processes in subsurface environments is a key issue for reactive transport modeling because simulating different processes requires developing different chemical–mathematical models. In this paper, two sorption processes (equilibrium and kinetics) are considered for modeling neptunium and uranium sorption in fractured rock. Based on different conceptualizatio...

PURPOSE Osteoporotic fracture is the main complication of osteoporosis. The current management is to discharge patients as early as possible so they can get back to their daily activities. Once discharged, there are three main issues relating to morbidity, mortality, and risk of a subsequent fracture that need to be addressed and discussed. Therefore, the aim of this systematic review was to su...

BACKGROUND Spine immobilization is one of the most frequently performed prehospital procedures. If trauma patients without significant risk for spine injury complications can be identified, spine immobilization could be selectively performed. The purpose of this study was to evaluate five prehospital clinical criteria-altered mental status, neurologic deficit, spine pain or tenderness, evidence...

OBJECTIVE To identify whether facial fracture repair in patients with traumatic optic neuropathy results in visual deterioration. DESIGN A retrospective analysis was performed of all patients admitted from 1992 through 1997 with the diagnosis of facial fracture and traumatic optic neuropathy. Vision was recorded before and after fracture repair using logarithm of the minimum angle of resoluti...
