1 Cross infection risk: Healthcare associated infection is defined as an infection that occurred in a patient in the healthcare setting in whom the infection was not present, or incubating, at the time of admission [1]. The World Health Organization reported in 2002 that the problem of nosocomial-acquired infection affects 1.4 million people worldwide. Annually, in the United Kingdom approximat...

Mobile image intensifiers are more readily used to assess acetabular cup placement when performing a total hip arthroplasty through a direct anterior approach. However, patient positioning affects pelvic tilt and rotation, which in turn requires proper C-arm fluoroscopy adjustments for image interpretation. The authors provide insight into the interpretation of acetabular cup positioning based ...

Findings of scientists touching lifestyle issues or popular habits are often provokingly and controversially discussed. A behavior that is repeated over numerous years is likely to have profound implications on a person's life, and possibly on the society as a whole. while several customs are adopted region-ally—for example, ingestion of yerba mate in south America or of hot spices in Asia—drin...

Nanos (Nos) has at least five different functions during the development of Drosophila melanogaster. In the pre-cellular blastoderm embryo, maternally derived Nos is required for formation of abdominal segments (Wang and Lehmann, 1991). Subsequently, maternal Nos is required in the embryonic germline precursors, the pole cells, to inhibit their division and promote migration into the somatic go...

OBJECTIVES After total hip arthroplasty (THA), restoration of hip center of rotation (COR) is essential to ensure stability of the prosthetic hip and longevity of the prosthesis. Our aim was to determine whether, and how, the COR changed postoperatively compared to the native COR following implantation of a cementless acetabular component in anatomical position and to compare the accuracy of cu...

BACKGROUND Concerns have been raised about the sequelae of metal-on-metal (MoM) bearings in total hip arthroplasty (THA). However, retrieval studies, which offer the best insight into the clinically relevant mechanisms of MoM wear, have followed predictable trends to date such as indicting cobalt-chromium (CoCr) metallurgy, cup design, high conformity between the head and cup, "steep cups," "mi...
