Abstract: A method of placing an implant for intervertebral fusion between adjacent vertebral bodies in a patient includes inserting the implant in a space between the adjacent vertebral bodies such that both a first intervertebral spacer body and a second intervertebral spacer body contact each of the adjacent vertebral bodies. The first intervertebral spacer body is spaced apart from the second intervertebral spacer body. An expandable container portion of the implant disposed between the first intervertebral spacer body and the second intervertebral spacer body is filled with fill material such that the expandable container expands to contact each of the adjacent vertebral bodies.

Abstract: Methods and systems are provided for rearranging content within resized sub-regions of a web page. First, resizing of a first sub-region of the webpage is detected by a user dragging a slidable border of the sub-region. A span value associated with dimensions of the first resized sub-region is determined and defining minimum dimensions of the first resized sub-region are defined. A subset of the dimensions of the first resized sub-region that fit within the span value is defined based on the minimum dimensions of the resized sub-region. The dimensions of the first resized sub-region include a fixed parameter and a dynamic parameter. The contents of a second sub-region of the webpage are rearranged in response to the resizing of the first resized sub-region and displaying displayed.
