G-Beam Invention

The purpose the G-Beam is to act as a load-sharing member through the medical and lateral longitudinal arches of the foot, specifically, for arthrodesis of the midfoot and hindfoot and most especially indicated for individuals with pathologic bone disease.

1. The G-Beam has a core diameter larger than the standard orthopedic screw. Their core diameter is SMALLER than the threads. This is why they fail.
2. The standard orthopaedic screws fail at the run out. This is usually at the talonavicular joint where the Bending Moments are the Greatest!
3. The shaft of the standard orthopaedic screw is smooth; it can loosen readily especially if fusion doesn’t occur as is common with Charcot arthrodesis. The result is motion, possible infection, loosening and hardware failure.
4. The G-Beam is spiral grooved to favor in growth and load sharing. Fenestrations favor ability to shoot platelets, or stem cells or antibiotics thru the Beam. They also favor bone in growth/ load sharing.

Different end caps may be selected for particular situations

In place is a proposed end cap to act as an interference screw for the lateral column Beam. Others may be low profile or pitched to compress but BEAMS principle purpose is LOAD SHARING with pathological bone. If successful arthrodesis occurs it is from bent wire frame technique. The beams use is to serve to create a stable foot even if the bone is too
diseased to ever unite.

Compared to standard screw the head is very low profile. High profile standard heads DESTROY the integrity of the already diseased metatarsal cortex when placed.
