Patients undergoing primary total hip arthroplasty (THA) have historically been over-transfused. In a district general hospital setting, the authors observed a significant downward trend in blood transfusion requirements in these patients over 6 years after a change in transfusion policy. The purpose of this study was to retrospectively analyze the change in transfusion practice and present the...

The mean body weight was 6.5 kg, 9.2 kg. In group of THAs cats, capital physeal fracture reason performing a THA six cases (60...

PURPOSE To assess the medium-term outcome of titanium uncemented modular tapered stems in revision total hip arthroplasty (THA). METHODS A questionnaire was mailed to 421 patients who underwent revision THA using a titanium uncemented modular tapered stem. 66 of whom underwent re-revision THA. The questionnaire was composed to reveal the Charnley classification, the modified 12-item Oxford hi...

Eleven new 12-amino-6,7,10,11-tetrahydro-7, 11-methanocycloocta[b]quinoline derivatives [tacrine (THA)-huperzine A hybrids, rac-21-31] have been synthesized as racemic mixtures and tested as acetylcholinesterase (AChE) inhibitors. For derivatives unsubstituted at the benzene ring, the highest activity was obtained for the 9-ethyl derivative rac-20, previously prepared by our group. More bulky s...

in order to evaluate the efficiency of empirical competition models for simulation of sugar beet (beta vulgaris l.) yield at interference with redroot pigweed (amaranthus retroflexus l.), a factorial experiment based on randomized complete block design with three replications was carried out. factors were weed densities (d1=1, d2= 4, d3= 8, d4=12 and d5=16 plants m-1 of row) and relative time o...

<div class="WordSection1"><p><strong>Background: </strong>Incidence of dislocation is about 1% to 6% for primary total hip arthroplasty (THA) and 4.8% 13% revision THA. The diameter the femoral head one important variables under control a surgeon. Larger heads with modern necks improve head-to-neck ratio, increase jump distance, reduce component impingement, instability ...

The purpose was to investigate the test-retest reliability of the 50-Foot Timed Walk (50FWT), and 30-Second Chair Stand Test (30CST) in the patients with total hip arthroplasty (THA). The study was a test-retest study. Thirty-seven patients with THA performed two trials for both the 30CTS and 50FWT on the same day with one hour interval. To assess reliability, the intra-class correlation coeffi...

BACKGROUND The value of the Internet to deliver preoperative education would increase if there was variability in questions patients want answered. This study's goal was to have patients consulting an orthopedic surgeon about undergoing either a total hip arthroplasty (THA) or a total knee arthroplasty (TKA) rate the importance of different questions concerning their care. METHODS We assemble...
