ONE IN FIVE PATIENTS REQUIRE CONVERSION TO ARTHROPLASTY AFTER NON-VASCULARIZED BONE GRAFTS IN PATIENTS WITH OSTEONECROSIS OF THE FEMORAL HEAD: A SYSTEMATIC REVIEW

Abstract Background Non-vascularized bone grafting (NVBG) icon track bar f250 has demonstrated to treat osteonecrosis of the femoral head (ONFH).There are a number of articles updating the use of NVBG to treat the ONFH, but the percentage of patients subsequently undergoing a total hip arthroplasty (THA) is controversial.Methods Several electronic

Many copepods display a swim-and-sink behaviour, which is not energetically efficient but probably aids in perceiving and capturing diatom chains.Here, computational fluid dynamics was employed to calculate the mechanical power required by a negatively buoyant, self-propelled copepod in swim-and-sink versus hovering.The results show that upward swi

Submarine pipelines are important resource delivery devices between land and ocean.For safety reasons, pipelines are often embedded beneath the seabed at a certain depth, to reduce the risk of direct damage to the pipeline.In the past, various kinds of detection equipment have been used for pipeline inspection, to ensure the normal operation of pip
