BACKGROUND In young patients with nontraumatic femoral head osteonecrosis with extensive and collapsed lesions, joint preservation is a goal if total joint arthroplasty is to be avoided. We evaluated… Expand
Evaluation of the Amount of Nitrogen and Phosphorus Absorption by the Aquatic Plant (Zizania latifolia)
A recent development to control of eutrophication is the ecological engineering, which involves using plants for water purification. Specifically, aquatic plant, Zizania latifolia, is profitable for… Expand

Comparison between component designs with different femoral head size in metal-on-metal total hip arthroplasty; multicenter randomized prospective study.
BACKGROUNDS/AIMS We prospectively studied 78 prostheses with conventional femoral head and 86 prostheses with large head (Magnum) of metal-on-metal total hip arthroplasty (MoM THA) with two years… Expand
BIPOLAR ENDOPROSTHESIS FOR OSTEONECROSIS OF THE FEMORAL HEAD: A 12-YEAR FOLLOW-UP OF 29 HIPS
Introduction: The results of noncemented press-fit bipolar hip endoprostheses were reviewed in patients with osteonecrosis of the femoral head. Materials and Methods: Twenty-nine hips in 24 patients… Expand
