Most reports regarding hardware removal involve the violation of the cortex to allow a specialized to tool to extract a retained fragment. This leaves large, unfilled screw holes that act as stress risers for months postoperatively. This article describes a novel technique to remove a retained intracortical screw fragment during total hip arthroplasty. Conversion of an intertrochanteric osteoto...

CONTEXT Football helmet face-mask attachment design changes might affect the effectiveness of face-mask removal. OBJECTIVE To compare the efficiency of face-mask removal between newly designed and traditional football helmets. DESIGN Controlled laboratory study. SETTING Applied biomechanics laboratory. PARTICIPANTS Twenty-five certified athletic trainers. INTERVENTION(S) The independe...

IEEE 802.15.4 systems suffer from serious MAC unreliability problem due to contention based MAC protocol used for channel access and its default parameter values. Reliability issues arise on case of energy efficiency when power management is enabled; packet loss when number of contending nodes is increased. A method to use IEEE 802.15.4 MAC protocol with reduced unreliability as the number of n...

INTRODUCTION: Management of tibial fractures can be complicated by infection of internal fixation hardware, resulting in increased morbidity and amputation rate. When removal of infected internal hardware with external fixation is not possible, salvage of the lower extremity is attempted through debridement, antibiotics, and soft tissue coverage. The purpose of this study is to investigate salv...

Fistula formation between bowel and total hip arthroplasty or revision arthroplasty hardware is rare. We present a case of a 78-year-old woman with protrusio of left hip arthroplasty and acetabular reconstruction hardware that caused direct perforation of the sigmoid colon and fistula formation between the sigmoid colon and the left hip joint. The patient underwent several joint debridements, s...

Clear and wide-angle images are essential to detect and trace objects for applications such as CCTV and unmanned vehicles. Fog, haze, and rain causes problem in getting clear image and lowers the detection rate of objects. To remove haze, we use median dark channel prior which can reduce the complexity of hardware. Image stitching stitches a number of images from multiple cameras into single wi...
