INTRODUCTION Proper imaging with radiographs plays an important role in preoperative planning and also assessing postoperative radiographic results. One of the major aims of any kind of lower limb corrective surgery such as corrective osteotomy or total knee arthroplasty, is restoration of the mechanical axis of the limb [1]. To achieve this, one needs to be able to assess the existing axis, pl...

The purpose of the present study was to compare lower limb alignment at initial ground contact between groups with normal and abnormal hip rotation range of motion. Male (n=8) and female (n=8) subjects performed an maximal drop jump diagonal side cut task ten to the left and ten to the right. Lower limb alignment was assessed through knee angle, hip angle, ankle angle, thigh rotation and shank ...

The diversity of surgical options for the management of distal femoral fractures reflects the challenges inherent in these injuries. These fractures are frequently comminuted and intra-articular, and they often involve osteoporotic bone, which makes it difficult to reduce and hold them while maintaining joint function and overall limb alignment. Surgery has become the standard of care for displ...

Despite the importance of maintaining good alignment to minimize resistive drag in swimming there is a paucity of literature relating to the effect of technique asymmetries on rotations of the body about a vertical axis (yaw). The purpose of this paper was to present an approach to analyzing the effect of technique asymmetries on rotations in swimming, exemplifying the process with a case study...

developing supernumerary limbs is a rare congenital condition that only a few cases have been documented. depending on the cause and developmental conditions, they may be single, multiple or complicated, and occur as a syndrome or associated with other anomalies. polymelia is defined as the presence of extra limb(s) which have been reported in human, mouse, chicken, calf and lamb. it seems that...

The visual alignment robot system for display and semiconductor fabrication process largely consists of multiaxes precision stage and vision peripherals. One of the central issues in a display or semiconductor mass production line is how to reduce the overall tact time by making a progress in the alignment technology between the mask and panel. In this paper, we suggest the kinematics of the 4P...

PURPOSE In total knee arthroplasty (TKA), it is important to restore neutral mechanical alignment. The purpose of this study was to assess whether the lower limb alignment is neutral in healthy Korean females and investigate the incidence of constitutional varus knees among them. MATERIALS AND METHODS Weight-bearing full-leg standing radiographs were obtained from 118 healthy females between ...

OBJECTIVE Osteoarthritis (OA) is a multifactorial condition. The progression of knee OA is determined in part by mechanical effects on local structures. One of the mechanical influences on cartilage loss is limb alignment. We explored the structural factors associated with malalignment in subjects with symptomatic OA. METHODS We conducted a cross-sectional assessment using The Boston Osteoart...
