subchondral insufficiency fracture of the femoral head (siffh) is characterized by acute onset hip pain without overt trauma. it appears as a low intensity band with bone marrow edema on t1-weighted mri. the most common course of treatment is protected weight bearing for a period of several weeks. total hip arthroplasty (tha) has been commonly used if the patient does not respond to the initial...

With the arrival of an aging society and progress surgical procedures, total hip arthroplasty (THA) has been carried out more more. However, postoperative pain severely affected patient’s recovery, there is currently no reliable analgesic method available. Evidence-based international expert consensus also recommends, compared to LIA, peripheral nerve block (PNB) as a central approach use in TH...

This paper shows that, with (partial) irreversibility, higher uncertainty reduces the impact effect of demand shocks on investment. Uncertainty increases real option values making firms more cautious when investing or disinvesting. This is confirmed both numerically for a model with a rich mix of adjustment costs, time-varying uncertainty, and aggregation over investment decisions and time, and...

The metabolic fate of tacrine [1,2,3,4-tetrahydro-9-acridinamine monohydrochloride monohydrate (THA)] was examined in rats, dogs, and humans. After administration of single oral doses of [14C]THA to rats, dogs, and humans, drug-derived material was well absorbed, with urinary excretion being the predominant route of radiolabel elimination. Metabolic profiling of plasma and urine from rats, dogs...

Purpose: Developmental dysplasia of the hip (DDH) increases the risk of secondary degenerative changes and subsequent total hip arthroplasty. The postoperative quality of life in patients with DDH who have been born and grown with this disability and adapted to it during the life, is one of the most challenging issues. This study aimed to compare the quality of life of patients with DDH before ...

(1) Background: Metal-on-metal (MoM) total hip arthroplasty (THA) and resurfacing (HRA) was presumed to provide superior functional outcomes compared metal-on-polyethylene (MoP) THA. (2) Methods: We muscle mass, power, step test asymmetry, patient-reported between MoM THA/HRA MoP A of 51 THA/HRAs 23 THAs participated in the cross-sectional study at a mean 6.5 (2.4–12.5) years postoperatively. M...

BACKGROUND Total hip arthroplasty (THA) is an increasingly common procedure among elderly individuals. Although conversion THA is currently bundled in a diagnosis related group (DRG) with primary THA, no study has identified whether patients undergoing conversion THA better resemble patients undergoing primary THA or revision THA. The American College of Surgeons National Surgical Quality Impro...
