Combining an implant and cement for prophylactic and/or preventative use for femoral neck augmention. A hole is drilled into the femoral neck. The hole is filled with an uncured filler cement after loose materials have been removed from the hole. Then, an open-ended tube, an implant, having openings through its walls is inserted into the hole and attached to the bone. Finally, additional filler cement is provided under pressure to the inside of the tubular implant. The filler cement flows into spaces in the bone structure via the tube wall openings. A sliding leak-tight fit between the implant and a cement injection tube permits delivery of cement at preselected locations along the implant length. Pressure is maintained until the filler cement has hardened. A strengthening factor up to 3 was measured when osteoporotic bone was strengthened.

The ski pole has normal strength when the pole is normally gripped at its handle and reduced strength when not gripped. The poles permanently deform when a predetermined level of excessive bending force is applied. The pole shaft is hollow with a short circumferential segment having reduced cross-section. When the handle is gripped, a plug slideable within the shaft spans the reduced cross-section and reinforces the pole at that region. When the handle is not gripped, the plug slides away from the reduced wall segment and reduces pole strength. A button on the handle connects to the plug by a rod, cable, hydraulics, pneumatics, etc. Alternatively, button actuation electrically drives a magnetic solenoid to move the plug. The weakened portion is replaceable so the pole is reusable.

Spinal modeling is based on a concept called spinal energy which assumes that the spine assumes a shape to minimize spinal energy. Spinal energy depends on parameters called stiffness coefficients. These parameters can be determined from human data which, by hypothesis, are universal for a large class of humans. The method adapts Newtons method to the manifold SO(3) to find a solution of model of the human spine. Where basins of attraction are small in Newtons method, homotopy methods are introduced to move from known solutions to unknown solutions. By setting the gradient of the spinal energy to zero, Newtons method is used to solve the inverse problem of finding stiffness coefficients from human data. A new approach to improving deformed spines uses the modeling method based on spinal energy. This approach preserves maximally the range of motion of the spine.

A spinal stabilization system for fixing vertebrae and sacrum having anterior and posterior aspects. The system comprises a plurality of rods or plates disposed over the vertebrae and/or sacrum, at least one rod or plate disposed anteriorly and at least one disposed posteriorly, and a plurality of bolts and nuts extending laterally through said vertebrae and/or sacrum and attached to the rods. A method for installing a spinal stabilization system to fix vertebrae and/or sacrum, comprising the steps of: exposing the spine anteriorly and posteriorly to reveal a level of vertebrae and/or sacrum, inserting a pair of beam means through the vertebrae and/or sacrum; repeating the exposing and inserting steps for a next level of vertebrae and/or sacrum; disposing column means over the anterior and posterior aspects of the two levels of vertebrae and/or sacrum; and connecting the ends of the beam means at each vertebrae and/or sacrum level to the column means.
