SLOB

Angular pressure of the femur presses the acetabular back wall backward and flatter. The hip ball displaces within this advancing pocket that it plows. In surgery, this flattened pushed out area is re-contoured

& reinforced with bone wedges. Even so it is in a socket too shallow to take on, again, what has already battered it handily. The native socket is like a yarmulke on a head. The SLOB uses stimulated marrow derived new bone to create a

football helmet over and beyond this Yarmulke.
