Este trabajo propone y evalúa una trayectoria hipotética de aprendizaje (THA) para los conceptos conjunto generador espacio generado. La THA se diseñó siguiendo el planteamiento Simon (1995), la heurística diseño modelos emergentes mecanismo reflexión sobre relación actividad-efecto. Se realizó un experimento con estudiantes universitarios evaluar si contribuyó al esperado conceptos. Para ello,...

Total hip metal arthroplasty (THA) constitutes an important proportion of the standard clinical implant usage in Medical Physics and Biomedical Engineering. A computational nonlinear optimization is performed with two commonly materials Metal-on-Metal (MoM) THA. Namely, Cast Co-Cr Alloy Titanium. The principal result numerical determination K adimensional-constant parameter model. Results from ...

Performing sports after total hip arthroplasty (THA) may be associated with a risk of Trauma (fracture and dislocation)Shorter implant survivalThere is no proof that trauma occurs more often than in healthy individuals, but sequelae may be more severe.Shorter implant survival due to repetitive high contact forces is a fact, due to increased wear. The 15 year survival in highly active patients s...

PURPOSE To report the radiological and clinical results of revision total hip arthroplasty (THA) with femoral impaction bone grafting (IBG). METHODS 4 men and 9 women (15 hips) aged 38 to 84 years underwent revision THA with femoral IBG using Elite plus stems for aseptic loosening or infection. RESULTS The mean follow-up duration was 7.7 years. The Harris hip score improved from 61.7 to 83....

The use of an elevated-rim acetabular liner in total hip arthroplasty (THA) is widely accepted. We sought to determine quantitatively the amount of additional stability provided by the elevated-rim liner as compared to the standard non-elevated liner. Furthermore, the stability of the hip with a 32-mm femoral head was compared to the standard 28-mm head. Our results show that a 15° elevated-rim...

We describe our technique and rationale using hybrid fixation for primary total hip arthroplasty (THA) at the Hospital for Special Surgery. Modern uncemented acetabular components have few screw holes, or no holes, polished inner surfaces, improved locking mechanisms, and maximised thickness and shell-liner conformity. Uncemented sockets can be combined with highly cross-linked polyethylene lin...
