BACKGROUND Patient age and comorbidity have been found to increase the length of hospital stay (LOS), readmissions, and mortality after surgery, including in elective primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). Whether the same applies in fast-track THA and TKA with early mobilization and an LOS aim of 2-4 days remains unanswered. METHOD A prospective study on pati...

BACKGROUND In our department, a vacuum bag with two lateral boards used to be utilized in order to maintain patients in the lateral decubitus position during THA. However, we recently changed this modality to a three-point fixation device for the pelvis in order to accurately control the position of the acetabular socket. The purpose of this study was to retrospectively compare the orientation ...

Phloracetophenone (2,4,6-trihydroxyacetophenone, THA) is a potent choleretic in the bile fistula rat, although the mechanism is unknown. In the present study, we examined how THA enhances bile secretion. Stepwise infusions of THA (1-4 micromol/min) in the isolated perfused rat liver resulted in an immediate and dose-dependent increase in bile flow (BF), which reached saturation. The increase in...

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...

The adul t ant ibody response is generally characterized by a marked degree of heterogeneity of affinity of the ant ibody for the antigenic de terminant (1, 2). With t ime after immunizat ion there appears to be a preferential selection of high affinity ant ibody-producing B lymphocytes resulting in an increase in the average affinity of the serum ant ibody (2-19). It is usually assumed tha t i...

BACKGROUND The use of total joint arthroplasties is increasing worldwide. In this work we aim to elucidate recent trends in demographics and perioperative outcomes of patients undergoing total hip (THA) or total knee arthroplasty (TKA). METHODS Data from the US Nationwide Impatient Sample between 1998 and 2008 were gathered for primary THAs and TKAs. Trends in patient age, comorbidity burden,...


 Tha?bit b. Qurra (d. 288/901), a Sabian of H?arra?n, and his descendants remained in their ancestral religion for six generations. Why did they persist despite pressure to convert? This article argues that religious self-identification as could be distinct advantage Baghdad’s elite circles. It focuses on Tha?bit’s great-grandson Abu?

BACKGROUND Our purpose was to evaluate outcome following arthroscopic treatment of femoroacetabular impingement (FAI) in middle-aged patients and to define risk factors for conversion to total hip arthroplasty (THA). METHODS This was a retrospective case series of 79 consecutive patients (40 to 65 years) undergoing arthroscopic treatment of FAI (follow-up ≥12 months). Outcome at follow-up was...

BACKGROUND The published data on pain and physical function before and after revision of total hip arthroplasty (THA) is scarce. The study reports the course and interrelationships of radiographic loosening, pain and physical function 5 year before and after a first revision THA. METHODS The study was based on the IDES-THA database. All patients with their first THA revision for aseptic loose...

Hip arthroscopy is considered one option in preserving the hip. Previous studies have shown age may be a predictor of failure; however, it unclear what factors lead to failure older patient. The purpose this study was determine associated with conversion total hip arthroplasty patient over 40 undergoing arthroscopy. 268 patients were identified who years age, had primary for FAI labral repair. ...
