T he N M D A class of g lu tam ate receptors have the unique property of binding some agonists, including glutam ate, for a very long period of time. O ne manifestation of this is tha t brief (1 ms) application of g lu tam ate (1 him) produces a slowly decaying current, the m ajor com ponent of which has a time constant of approxim ately 200 ms.

Accurate placement of components is imperative for successful outcomes after total hip arthroplasty (THA). Although technology-assisted techniques offer the potential for greater accuracy in prosthesis positioning, the need for additional resources prevents their widespread use. The goal of this study was to compare primary THA procedures performed with and without intraoperative fluoroscopic g...

PURPOSE To compare the midterm outcome in 12 women who underwent total hip arthroplasty (THA) for rapidly destructive coxarthrosis (RDC) and in 12 controls who underwent THA for osteoarthritis. METHODS Records of 12 women aged 50 to 80 (mean, 72.3) years who underwent THA for RDC after a mean of 9 (range, 4-11) months since symptom onset were reviewed. They were compared with 12 age-and sex-m...

BACKGROUND Impingement can be a serious complication after total hip arthroplasty (THA), and is one of the major causes of postoperative pain, dislocation, aseptic loosening, and implant breakage. Minimally invasive THA and computer-navigated surgery were introduced several years ago. We have developed a novel, computer-assisted operation method for THA following the concept of "femur first"/"c...

Background According to the results of Russian studies, coxitis occurs in 56% patients (pts) with AS. At same time, need for total hip arthroplasty (THA) is only 8%, which associated use biologic disease-modifying anti-rheumatic drugs (bDMARDs). Objectives The aim study was compare macroscopic changes bone tissue femoral heads (FH) and acetabulums pts AS who received did not receive bDMARDs. Me...

Long-term administration of 9-amino-1,2,3,4-tetrahydroacridine (THA) has been reported to produce marked clinical improvement in patients suffering from Alzheimer's disease. The dramatic enhancement of cognitive function seen with THA contrasts sharply with the modest improvements seen with other forms of anticholinesterase therapy, suggesting that additional mechanisms might play a role in its...

The long-term durability of polyethylene lining total hip arthroplasty (THA) mainly depends on periprosthetic osteolysis due to wear particles, especially in young active patients. In hip simulator study, reports revealed significant wear reduction of the alumina ceramic-on-polyethylene articulation of THA compared with metal-on-polyethylene bearing surfaces. However, medium to long-term clinic...

We investigated the isokinetic performance of hip muscles and clinical outcomes after revision total hip arthroplasty (THA) via same anterolateral approach used in primary surgery. Thirty patients who had undergone previous THA via an anterolateral approach underwent both acetabular and femoral component revision after aseptic loosening. The Harris Hip Score (HHS) was evaluated during a minimum...

The aim of this study was to evaluate the incidence of early mortality and identify risk factors for early death following modern uncemented THA. Between 2000 and 2006, we identified patients who died within 90days of THA. Demographics, comorbidities, laboratory studies, and complications were analyzed as risk factors for mortality. 38 of 8261 patients undergoing THA (0.46%) died within 90days ...
