BACKGROUND The incidence of distal femur fracture in the elderly has been increasing recently, and commonly occurs with osteoporosis. Retrograde intramedullary nailing has been considered a good surgical option for distal femur fracture. The purpose of the present study was to present our surgical results with retrograde intramedullary nailing for distal(More)
BACKGROUND The authors examined whether poor preoperative glucose control, as indicated by the hemoglobin A1c (HbA1c) level of more than 8%, is associated with postoperative wound and infectious complications in diabetic patients that have undergone total knee arthroplasty (TKA). METHODS One hundred and sixty-seven TKAs performed in 115 patients with type(More)
BACKGROUND Periprosthetic supracondylar fractures of the femur after total knee arthroplasty are not common but are usually difficult to treat due to the advanced age of patients and frequently accompanying osteoporosis. Retrograde intramedullary nailing can be effective in promoting healing of these fractures by providing sufficient stability, but the(More)
We propose a 3D gaze-tracking method that combines accurate 3D eye- and facial-gaze vectors estimated from a Kinect v2 high-definition face model. Using accurate 3D facial and ocular feature positions, gaze positions can be calculated more accurately than with previous methods. Considering the image resolution of the face and eye regions, two gaze vectors(More)
The purpose of this study was to analyze the anthropometric data from MRI images that were obtained from the non-arthritic knees in Asian adults, and to identify the existence of morphologic differences between age groups. This cross-sectional study included knee MR images of 535 patients (273 males, 262 females) taken for the evaluation of soft-tissue(More)
To the Editor: We read with great interest the manuscript by Kim et al. 1) entitled " Retrograde Intramedullary Nailing for Distal Femur Fracture with Osteoporosis " in the current issue of your journal. We must congratulate the authors for this study. However, we would like to elaborate on few points and would like to draw attention of authors and readers(More)
PURPOSE To identify the effects of using a Ti-Ni shape memory alloy ring shaped bone fixator (SMA-rBF) during the retrograde nailing of supracondylar femoral fractures. MATERIALS AND METHODS The authors reviewed 25 patients with a supracondylar femoral fracture treated by retrograde intramedullary nailing with or without SMA-rBF (group S, 12/25; group N,(More)
Experimental and clinical studies on the accuracy of the intramedullary alignment method have produced different results, and few have addressed accuracy in the sagittal plane. Reported deviations are not only attributable to the alignment method but also to radiological errors. The purpose of this study was to evaluate the accuracy of the intramedullary(More)
