“…Mohd Yusof Baharuddin et al. of the University of Malaya, Kuala Lumpur, Malaysia, investigated the designing of a cementless femoral stem 316L stainless steel using the investment casting technique for their specific population. Using finite element analysis, they showed that the maximum von Mises stress was 66.88 MPa proximally with a safety factor of 2.39 against endosteal fracture, and micromotion was 4.73 μm, which promotes osseointegration.…”

In this Editor's Review, articles published in 2014 are organized by category and briefly summarized. We aim to provide a brief reflection of the currently available worldwide knowledge that is intended to advance and better human life while providing insight for continued application of technologies and methods of organ Replacement, Recovery, and Regeneration. As the official journal of the International Federation for Artificial Organs, the International Faculty for Artificial Organs, the International Society for Rotary Blood Pumps, the International Society for Pediatric Mechanical Cardiopulmonary Support, and the Vienna International Workshop on Functional Electrical Stimulation, Artificial Organs continues in the original mission of its founders "to foster communications in the field of artificial organs on an international level." Artificial Organs continues to publish developments and clinical applications of artificial organ technologies in this broad and expanding field of organ Replacement, Recovery, and Regeneration from all over the world. We take this time also to express our gratitude to our authors for offering their work to this journal. We offer our very special thanks to our reviewers who give so generously of time and expertise to review, critique, and especially provide meaningful suggestions to the author's work whether eventually accepted or rejected. Without these excellent and dedicated reviewers, the quality expected from such a journal could not be possible. We also express our special thanks to our Publisher, John Wiley & Sons, for their expert attention and support in the production and marketing of Artificial Organs. We look forward to reporting further advances in the coming years.

“…Besides, DMLS also permitted the fabrication of complex shapes of peculiar ASEAN hip morphological and reduced metal powder waste during fabrication [9]. The previous study by the researcher using the investment casting technique [10] and metal injection molding (MIM) technique [11] demonstrate a higher shrinkage rate compared to the DMLS technique.…”

Total hip replacement (THR) is the most popular surgery been performed in orthopedic surgery due to the inclination of musculoskeletal disorder and the aging population worldwide. However, the implant’s cost-burdened the patient, especially in the ASEAN region. The main objective of this study was to fabricate the low-cost hip implant using direct laser metal sintering (DMLS). The framework starts with the three dimensional of hip anthropometric datasets from computed tomography scanner, followed with the design of hip implant, computational analysis using finite element, and finally fabrication using DMLS technique. The morphological results demonstrated the value of neck-shaft angle was 130.46º, and the femoral head offset of 30.35 mm. The finite element analysis showed strain distribution was 65 MPa for the implant in metaphyseal region and 110 MPa for intact femur under staircase physiological loading which indicated inhibition of stress shielding at medical calcar region, and micromotion was 4.8 µm which prevent the formation of fibrous tissue and promoting osseointegration between implant-bone interfaces. This study proposed the fabrication using the DMLS technique, which produced accurate implant with low-cost, which suits the ASEAN hip morphology that prolongs implant lifetime.

“…In order to overcome this, many researchers have investigated different designs by finite element approach. These computational models have been successfully used to investigate the biomechanical responses due to external stimuli of tissues and implants [5][6][7][8][9][10][11][12][13]. Some studies have focused on modifying the hip stems using various materials and designs [4,14,15].…”

The objective of this study is to develop a design space for selecting porous titanium alloy femoral stems with different stiffnesses for fatigue applications. Finite element models of stems incorporating porous structure are constructed to provide different stem stiffness. The effective material properties obtained from compression tests of these porous structures are used to model simplified femoral solid stems with porosities of ranging from 20 – 90%. By using appreciate fatigue failure criterion, a fatigue design space is determined with factor of safety Nf >1.1. The developed design space provides designers means to design safe porous stems.
