PURPOSE The aim of this study was to describe the dislocation rates, reoperation rates and mortality 30 day and one year following THA with AVANTAGE® dual mobility cup among dementia patients with an acute displaced intracapsular femoral neck fracture. PATIENTS AND METHODS From 2010 to 2014 we identified 20 hip fracture patients with dementia, who have had total hip arthroplasty with the AVAN...

Abstract Background Stress shielding after total hip arthroplasty (THA) leads to loss of bone mineral density (BMD) around the femoral implants, particularly in proximal area. Loss BMD implant is likely occur within 1 year THA; however, its severity depends on patient characteristics. This study evaluated preoperative factors correlated with zone 7 THA. Methods retrospective cohort included 48 ...

Tacrine (THA) and physostigmine (PHS) have been used in Alzheimer's disease therapy for their anticholinesterasic activity. Here we show that THA is taken up in rat lysosomes in an energy-dependent manner, and that it is also accumulated in acidic compartments of rat thymocytes and neuroblastoma cells. A concentration of THA less than 1 mM dissipated the pH gradient (delta pH) in all the above ...

BACKGROUND This meta-analysis compared clinical outcomes of arthroplasty vs. osteosynthesis for displaced femoral neck fractures. METHODS Meta-analysis was performed on the difference in revision rate and overall mortality between participants undergoing osteosynthesis vs. total hip arthroplasty (THA), osteosynthesis vs. hemiarthroplasty (HA), or THA vs. HA. RESULTS Pooled direct and indire...

OBJECTIVES To collect data of randomised controlled trials (RCTs) and clinical controlled trials (CCTs) for evaluating the effects of enhanced recovery after surgery on postoperative recovery of patients who received total hip arthroplasty (THA) or total knee arthroplasty (TKA). METHODS Relevant, published studies were identified using the following key words: arthroplasty, joint replacement,...

BACKGROUND Orthopaedic surgeons frequently encounter patients with ankylosing spondylitis who would benefit from various types of lower limb operations; however, some of these patients present challenges for anesthesiologists. CASE DESCRIPTION We report the case of a 65-year-old patient with a fractured femoral component 30 years after a cemented THA. The patient had severe tracheal stenosis ...

High-performance multistage data converters and sub-sampling frequency downconverters typically require track and hold amplifiers (THAs) with high sampling rates and high linearity. This paper presents a THA for sub-sampling communications applications based on a diode bridge design with high-speed Schottky diodes and an improved current source approach for enhanced linearity. Implemented in a ...

Abstract Objective To provide guidelines for surgery and reduce the incidence of fracture, this study analyzed relationship between femoral fracture related factors in direct anterior approach (DAA) total hip arthroplasty (THA) lateral decubitus position. Method A retrospective series 273 consecutive patients who underwent THA with DAA position was analyzed. Each performed by same surgeon a con...

BACKGROUND Failure of THA or TKA to meet a patient's expectations may result in patient disappointment and litigation. However, there is little evidence to suggest that surgeons can consistently anticipate which patients will benefit from those interventions. QUESTIONS/PURPOSES To determine the ability of surgeons to identify, in advance of surgery, patients who will benefit from THA or TKA a...

Concerns about the effects of global warming on crop yields have been raised due to stagnating yield progress in recent years. However, an understanding changes temperature and rainfall throughout cycle historical is lacking Europe (EU). In this study, positive wheat, barley, rice, maize EU (1961–2019) was significant, with rates 0.05, 0.04, 0.07 Tha?1year?1, for four crops respectively. Much h...
