A multicenter survey on profile of care for hip fracture: predictors of mortality and disability.

, 2010
Summary Because delay in time to surgery beyond 24–48 h has been observed in many studies to be associated with adverse outcomes, a survey in nine centers in Italy was undertaken to examine the impact of time to surgery on mortality and disability at 6 ...

Investigation on the Applicability of Several Fracture Criteria to the Mixed Mode Brittle Fractures

Advances in Mechanical Engineering, 2013
Mixed mode brittle fractures are very common failure behavior for cracked brittle materials under loading, and therefore, the prediction of the mixed mode brittle fractures is significant.

Numerical Modelling of Interaction between Hydraulic Fractures and Natural Fractures by Using the Extended Finite Element Method

Advances in Civil Engineering, 2020
Natural fractures usually develop in shale reservoirs. Thereby, in the process of hydraulic fracturing, it is inevitable that hydraulic fractures will intersect with natural fractures.

FRACTURE CRITERIA FOR COMBINED MODE CRACKS

, 1978
The complex variable method is employed to analyse the energy release rate for combined mode cracks. A functional integral equation, which contains no singularity, is derived for a branched crack problem by a functional transformation. The integrand φ_1'(z) is expanded in eigenfunctions. The energy fracture criterion for the combined mode (K_Ⅰ and K_Ⅱ)

Zoledronic Acid in Reducing Clinical Fracture and Mortality after Hip Fracture.

, 2007
BACKGROUND: Mortality is increased after a hip fracture, and strategies that improve outcomes are needed. METHODS: In this randomized, double-blind, placebo-controlled trial, 1065 patients were assigned to receive yearly intravenous zoledronic acid (at a
