PURPOSE. To evaluate the chromium level of the salvaged blood in patients undergoing revision total hip arthroplasty (THA). METHODS. Records of 7 women and one man aged 54 to 83 (mean, 64.3) years who underwent revision THA for aseptic loosening of the acetabular component (n=6), osteolysis of the acetabulum (n=1), or migration of the outer head (n=1) were reviewed, as were 2 controls who under...

I n t r o d u c t i o n . In this paper, we s tudy the following quest ion: How long a cycle must there be in a 3-connected 3-regular graph on n vertices? For planar graphs this question goes back to T a i t [6], who conjectured tha t any planar 3-connected 3-regular graph is hamiltonian. T u t t e [7] disproved this conjecture by finding a counterexample on 46 vertices. Using Tu t t e ' s exam...

BACKGROUND Total hip arthroplasty (THA) for poliomyelitis is a problematic procedure due to difficulty in positioning the cup of the prosthesis in the true acetabulum and the risk of dislocation after THA due to the low muscle tone. METHODS We herein present a case of bilateral hip pain with a history of poliomyelitis. Radiograph showed bilateral hip osteoarthritis caused by hip dysplasia due...

BACKGROUND All patients with total hip arthroplasty (THA), especially those with metal-on-metal (MM) THA, are exposed to metallic particles and ions, which may cause total or site-specific mortality. We analyzed the causes of total and site-specific mortality among a cohort of patients with MM and with metal-on-polyethylene (MP) THA after a long follow-up time. METHODS Standardized mortality ...

This study was designed to evaluate trends in incidence and treatment patterns for intracapsular hip fractures and to evaluate risk factors for complications and mortality. Patients with an intracapsular hip fracture who underwent internal fixation, hemiarthroplasty, or total hip arthroplasty (THA) were identified from a 5% nationwide sample of Medicare data (1998-2007). The authors identified ...

'Fast-track' surgery was introduced more than 20 years ago and may be defined as a co-ordinated peri-operative approach aimed at reducing surgical stress and facilitating post-operative recovery.The fast-track programmes have now been introduced into total hip arthroplasty (THA) surgery with reduction in post-operative length of stay, shorter convalescence and rapid functional recovery without ...

UNLABELLED Hip osteoarthritis (OA) is a degenerative disease, and total hip arthroplasty (THA) is one of the surgical procedures of choice to improve the OA patient's quality of life. Without a rehabilitation program, THA patients will develop functional limitations. A randomized double-blind trial was performed between July 2009 and October 2011 to compare in a short follow-up time two groups ...

BACKGROUND Tranexamic acid (TXA) has been associated with decreased blood loss and transfusion after total hip arthroplasty (THA) and total knee arthroplasty (TKA). The purpose of this study was to examine both transfusion utilization and the economic impact of a Process Improvement Project implementing TXA for THA and TKA. METHODS After standardization of TXA administration in THA and TKA pa...

L-threo-3-Hydroxyaspartate dehydratase (L-THA DH, EC 4.3.1.16), which catalyses the cleavage of L-threo-3-hydroxyaspartate (L-THA) to oxalacetate and ammonia, has been purified from the soil bacterium Pseudomonas sp. T62. In this report, the gene encoding L-THA DH was cloned and expressed in Escherichia coli, and the gene product was purified and characterized in detail. A 957-bp nucleotide fra...
