Quantifying soft-tissue tension around the hip joint during total hip arthroplasty remains difficult. In this study, a three-dimensional computer-aided design model was developed to clarify how component position in total hip arthroplasty contribu...
There are many designs of the femoral stem of a cemented total hip arthroplasty, and mechanical failure of the stem is caused by several factors related to the cement, such as failure of the cement. Optimization of the shape of the stem, especiall...

The success of total hip arthroplasty (THA) in improving joint function and reducing pain is regarded as one of the great achievements of modern medicine. Today, most femoral stems with cementless fixation are made of either cobalt-chrome-molybden...

Titanium tends to seizure with other metals, so titanium unfits thread rolling for dental implant with φ3mm diameter or less. Therefore we lubricate the contact point and prevent the seizure by applying a textured surface on the die. We were exami...

This study is aimed to show if hip joint loads during walking could be reduced by a slight gait modification. Six healthy adult subjects (mean (SD) age 22 (0.0) years, mean (SD) height 1.68 (0.04) m, mean (SD) weight 60.2 (7.9) kg) took part in th...
